}
}
```
## Common Scenarios
### Scenario 1: New UI5 Project Setup
1. Install linter
2. Create configuration (use template)
3. Add npm scripts to package.json
4. Run initial lint
5. Fix auto-fixable issues
6. Review remaining issues
### Scenario 2: Preparing for UI5 2.x Migration
1. Run linter to find all issues
2. Focus on critical issues first
3. Apply automatic fixes
4. Review autofix limitations document
5. Manually fix unsupported APIs
6. Address Core API issues (#619, #620)
7. Update manifest to v2
8. Fix no-outdated-manifest-version, no-removed-manifest-property issues
9. Verify all issues resolved
## Troubleshooting
### Common Issues
**Symptom**: Linter reports parsing errors
**Solution**: Check for syntax errors in config files
**Symptom**: Autofix doesn't work
**Solution**: Check autofix limitations in `references/autofix-complete.md`
**Symptom**: Performance issues on large codebase
**Solution**: Add ignore patterns, use targeted linting
### Known Limitations
- Cannot convert synchronous to async patterns
- Limited Core/Configuration API autofix (~50 APIs)
- jQuery.sap API support limited to basic methods
- Node.js modules not automatically discovered
## Best Practices
### 1. Run Linter Early and Often
- Add pre-commit hook for instant feedback
- See templates/husky-pre-commit.template
### 2. Use Configuration File for Persistent Settings
- Environment-specific configurations
- Project-wide ignore patterns
### 3. Fix Issues Incrementally
1. Fix errors first
2. Then fix warnings
3. Review and test after each step
### 4. Document Suppressed Rules
- Document team-wide suppressions with explanations
- Use sparingly and with clear justifications
### 5. Integrate with CI/CD
- Fail builds on errors, allow warnings
- Generate reports for stakeholders
### 6. Monitor Performance
- Track linting performance over time

# UI5 Linter - Advanced CI/CD Integration
**Source**: [https://github.com/UI5/linter/blob/main/.github/workflows/ci.yml](https://github.com/UI5/linter/blob/main/.github/workflows/ci.yml)
**Last Updated**: 2025-11-21
**UI5 Linter Version**: 1.20.5
---
## Overview
This guide covers advanced CI/CD integration patterns for UI5 Linter, including the UI5 Linter project's own CI workflow, coverage reporting, license checking, dependency analysis, and multi-environment strategies.
---
## UI5 Linter's Own CI Workflow (Real-World Example)
The UI5 Linter project itself uses a comprehensive CI pipeline that demonstrates best practices.
### Complete Workflow
**File**: `.github/workflows/ci.yml`
**Note**: This is the actual CI workflow used by the UI5 Linter project itself, demonstrating production best practices.
```yaml
name: CI
on:
push:
branches: [ main ]
pull_request:
branches: [ main ]
permissions: {}
jobs:
test:
name: Test
runs-on: ubuntu-24.04
steps:
- name: Checkout code
uses: actions/checkout@v6
- name: Setup Node.js
uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
- name: Install dependencies
run: npm ci --engine-strict
- name: Run linter
run: npm run lint
- name: Check licenses
run: npm run check-licenses
- name: Check dependencies
run: npm run depcheck
- name: Build
run: npm run build-test
- name: Run tests with coverage
run: npm run coverage
- name: Report coverage
uses: coverallsapp/github-action@v2.3.6
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
continue-on-error: true
```
### Key Patterns Demonstrated
**1. Engine-Strict Installation**
```yaml
- name: Install dependencies
run: npm ci --engine-strict
```
**Why**: Fails fast if Node.js version is incompatible, preventing hidden issues.
---
**2. Multi-Step Quality Checks**
```yaml
- run: npm run lint # Code quality
- run: npm run check-licenses # Legal compliance
- run: npm run depcheck # Dependency health
- run: npm run build-test # Build verification
- run: npm run coverage # Test coverage
```
**Why**: Layered validation catches different types of issues.
---
**3. Coverage Reporting**
```yaml
- uses: coverallsapp/github-action@v2.3.6
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
continue-on-error: true
```
**Why**: `continue-on-error` prevents workflow failure if Coveralls is down.
---
**4. Minimal Permissions**
```yaml
permissions: {}
```
**Why**: Security best practice - grant only necessary permissions.
---
## Advanced GitHub Actions Patterns
### Multi-Platform Testing
Test across operating systems:
```yaml
name: Cross-Platform Lint
on: [push, pull_request]
jobs:
lint:
strategy:
matrix:
os: [ubuntu-24.04, macos-latest, windows-latest]
node: ['24', '22']
runs-on: ${{ matrix.os }}
steps:
- uses: actions/checkout@v6
- name: Setup Node.js
uses: actions/setup-node@v6
with:
node-version: ${{ matrix.node }}
cache: 'npm'
- run: npm ci
- name: Run UI5 Linter
run: npm run lint
```
**Use Cases**:
- Ensure linter works on all platforms
- Catch platform-specific path issues
- Verify compatibility with multiple Node versions
---
### Multi-Job Workflow with Dependencies
Organize checks into separate jobs:
```yaml
name: Complete Validation
on: [push, pull_request]
jobs:
lint-ui5:
name: UI5 Linter
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
- run: npm ci
- run: npm run lint
lint-js:
name: ESLint
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
- run: npm ci
- run: npm run eslint
test:
name: Tests
needs: [lint-ui5, lint-js] # Only run if linting passes
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
- run: npm ci
- run: npm test
deploy:
name: Deploy
needs: test # Only deploy if tests pass
if: github.ref == 'refs/heads/main'
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- run: echo "Deploy to production"
```
**Benefits**:
- Parallel execution (faster)
- Clear separation of concerns
- Conditional deployment
---
### Caching for Performance
Optimize workflow performance with caching:
```yaml
jobs:
lint:
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- name: Setup Node.js
uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm' # Automatic npm cache
- name: Cache UI5 Linter results
uses: actions/cache@v4
with:
path: .ui5lint-cache
key: ui5lint-${{ hashFiles('webapp/**/*.js', 'webapp/**/*.xml', 'ui5lint.config.*') }}
restore-keys: |
ui5lint-
- run: npm ci
- name: Run UI5 Linter
run: npm run lint
```
**Performance Gain**: 30-50% faster on cache hit
---
### Diff-Based Linting (Lint Only Changed Files)
Lint only files changed in PR:
```yaml
name: Incremental Lint
on: [pull_request]
jobs:
lint-changed:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v6
with:
fetch-depth: 0 # Fetch all history for diff
- uses: actions/setup-node@v6
with:
node-version: '20'
cache: 'npm'
- run: npm ci
- name: Get changed files
id: changed-files
run: |
echo "files=$(git diff --name-only --diff-filter=ACMRT ${{ github.event.pull_request.base.sha }} ${{ github.sha }} | grep -E '\.(js|xml|json)$' | tr '\n' ' ')" >> $GITHUB_OUTPUT
- name: Lint changed files
if: steps.changed-files.outputs.files != ''
run: |
npx ui5lint ${{ steps.changed-files.outputs.files }}
```
**Benefits**:
- Faster on large codebases
- Immediate feedback on changes
---
## Coverage Reporting Integration
### Coveralls Integration
**Setup**:
```bash
npm install --save-dev nyc
```
**package.json**:
```json
{
"scripts": {
"test": "ava",
"coverage": "nyc npm test",
"lint": "ui5lint"
},
"nyc": {
"reporter": ["lcov", "text"],
"include": ["src/**/*.js"],
"exclude": ["test/**"]
}
}
```
**GitHub Actions**:
```yaml
- name: Run tests with coverage
run: npm run coverage
- name: Upload to Coveralls
uses: coverallsapp/github-action@v2.3.6
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
continue-on-error: true
```
---
### Codecov Integration
```yaml
- name: Run tests with coverage
run: npm run coverage
- name: Upload to Codecov
uses: codecov/codecov-action@v3
with:
files: ./coverage/lcov.info
flags: unittests
name: codecov-umbrella
fail_ci_if_error: true
```
---
## License Checking
Ensure all dependencies have acceptable licenses:
**package.json**:
```json
{
"scripts": {
"check-licenses": "license-checker --onlyAllow 'MIT;Apache-2.0;BSD-2-Clause;BSD-3-Clause;ISC'"
},
"devDependencies": {
"license-checker": "^25.0.1"
}
}
```
**GitHub Actions**:
```yaml
- name: Check licenses
run: npm run check-licenses
```
**Why**: Legal compliance, prevent GPL contamination
---
## Dependency Checking
Identify unused or missing dependencies:
**package.json**:
```json
{
"scripts": {
"depcheck": "depcheck --ignores='@types/*,eslint-*'"
},
"devDependencies": {
"depcheck": "^1.4.3"
}
}
```
**GitHub Actions**:
```yaml
- name: Check dependencies
run: npm run depcheck
```
**Why**: Keep dependencies clean, reduce bundle size
---
## Security Scanning
### npm audit
```yaml
- name: Security audit
run: npm audit --audit-level=moderate
continue-on-error: true # Don't fail on low/moderate
```
---
### Snyk Integration
```yaml
- name: Run Snyk
uses: snyk/actions/node@master
env:
SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
with:
args: --severity-threshold=high
```
---
## Artifact Management
Save lint results as artifacts:
```yaml
jobs:
lint:
runs-on: ubuntu-24.04
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
- run: npm ci
- name: Run UI5 Linter (JSON output)
run: npm run lint -- --format json 2> lint-diagnostics.log | tee lint-results.json
continue-on-error: true
- name: Run UI5 Linter (HTML report)
run: npm run lint -- --format html 2> lint-diagnostics.log | tee lint-report.html
continue-on-error: true
- name: Upload JSON results
uses: actions/upload-artifact@v5
if: always()
with:
name: lint-results-json
path: lint-results.json
retention-days: 30
- name: Upload HTML report
uses: actions/upload-artifact@v5
if: always()
with:
name: lint-report-html
path: lint-report.html
retention-days: 30
- name: Check for errors
run: |
if [ ! -f lint-results.json ]; then
echo "❌ Lint results file not found"
exit 1
fi
if ! jq '[.[].errorCount] | add' lint-results.json > /tmp/error_count 2>/dev/null; then
echo "❌ Failed to parse lint-results.json"
exit 1
fi
ERROR_COUNT=$(cat /tmp/error_count)
ERROR_COUNT=${ERROR_COUNT:-0}
if [ "$ERROR_COUNT" -gt 0 ]; then
echo "❌ Found $ERROR_COUNT linting errors"
exit 1
fi
```
**Benefits**:
- Download reports for review
- Historical tracking
- Share with non-technical stakeholders (HTML)
---
## Pull Request Comments
Add lint results as PR comments:
```yaml
jobs:
lint-pr:
runs-on: ubuntu-latest
if: github.event_name == 'pull_request'
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '20'
cache: 'npm'
- run: npm ci
- name: Run UI5 Linter
id: lint
run: |
npm run lint -- --format markdown > lint-results.md || true
echo "results<<EOF" >> $GITHUB_OUTPUT
cat lint-results.md >> $GITHUB_OUTPUT
echo "EOF" >> $GITHUB_OUTPUT
- name: Comment PR
uses: actions/github-script@v6
with:
script: |
github.rest.issues.createComment({
issue_number: context.issue.number,
owner: context.repo.owner,
repo: context.repo.name,
body: '## UI5 Lint Results\n\n${{ steps.lint.outputs.results }}'
})
```
---
## GitLab CI Integration
**File**: `.gitlab-ci.yml`
```yaml
stages:
- lint
- test

return results.sum { it.errorCount } == 0
}
}
steps {
sh 'npm test'
}
}
}
}
```
---
## Pre-Commit Hooks (Advanced)
### Lint-Staged with Auto-Fix
**package.json**:
```json
{
"husky": {
"hooks": {
"pre-commit": "lint-staged"
}
},
"lint-staged": {
"webapp/**/*.{js,xml}": [
"ui5lint --fix",
"ui5lint",
"git add"
],
"webapp/manifest.json": [
"ui5lint --fix",
"ui5lint"
]
}
}
```
**Setup**:
```bash
npm install --save-dev husky lint-staged
npx husky install
npx husky add .husky/pre-commit "npx lint-staged"
```
---
### Commit Message Linting
Enforce conventional commits (like UI5 Linter):
**package.json**:
```json
{
"devDependencies": {
"@commitlint/cli": "^17.0.0",
"@commitlint/config-conventional": "^17.0.0"
}
}
```
**commitlint.config.mjs**:
```javascript
export default {
extends: ['@commitlint/config-conventional'],
rules: {
'type-enum': [2, 'always', [
'feat', 'fix', 'docs', 'style', 'refactor', 'test', 'chore'
]],
'scope-enum': [2, 'always', [
'linter', 'autofix', 'docs', 'ci'
]]
}
};
```
**Husky Hook**:
```bash
npx husky add .husky/commit-msg "npx commitlint --edit $1"
```
---
## Monorepo Integration
For monorepos with multiple UI5 apps:
```yaml
name: Monorepo Lint
on: [push, pull_request]
jobs:
find-apps:
runs-on: ubuntu-24.04
outputs:
matrix: ${{ steps.set-matrix.outputs.matrix }}
steps:
- uses: actions/checkout@v6
- id: set-matrix
run: |
APPS=$(find apps -name "ui5.yaml" -exec dirname {} \; | jq -R -s -c 'split("\n")[:-1]')
echo "matrix=$APPS" >> $GITHUB_OUTPUT
lint:
needs: find-apps
runs-on: ubuntu-24.04
strategy:
matrix:
app: ${{ fromJson(needs.find-apps.outputs.matrix) }}
steps:
- uses: actions/checkout@v6
- uses: actions/setup-node@v6
with:
node-version: '24'
cache: 'npm'
cache-dependency-path: '${{ matrix.app }}/package-lock.json'
- name: Install dependencies
run: npm ci
working-directory: ${{ matrix.app }}
- name: Lint ${{ matrix.app }}
run: npm run lint
working-directory: ${{ matrix.app }}
```
---
## Environment-Specific Configurations
Use different configs for dev vs CI:
**ui5lint.config.js** (dev):
```javascript
export default {
ignores: ["webapp/thirdparty/**"]
};
```
**.ui5lint.ci.config.js** (CI):
```javascript
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**" // More aggressive ignores for CI
]
};
```
**GitHub Actions**:
```yaml
- name: Lint (CI config)
run: npm run lint -- --config .ui5lint.ci.config.js
```
---

# UI5 Linter - Complete Autofix Reference
**Source**: [https://github.com/UI5/linter/blob/main/docs/Scope-of-Autofix.md](https://github.com/UI5/linter/blob/main/docs/Scope-of-Autofix.md)
**Last Updated**: 2025-11-21
**UI5 Linter Version**: 1.20.5
---
## Overview
The UI5 Linter's autofix feature (`--fix` flag) can automatically correct certain categories of issues. However, the documentation explicitly states: **"This list is not exhaustive; there are more APIs that are currently not replaced automatically."**
This reference provides comprehensive coverage of what can and cannot be automatically fixed.
---
## Using Autofix
### Basic Usage
```bash
# Apply fixes to all files
ui5lint --fix
# Fix specific files
ui5lint --fix "webapp/**/*.js"
# Preview fixes without applying (dry-run mode)
UI5LINT_FIX_DRY_RUN=true ui5lint --fix
```
### Dry-Run Mode
Before applying fixes, preview changes using the environment variable:
```bash
UI5LINT_FIX_DRY_RUN=true ui5lint --fix
```
This shows what would be changed without modifying any files.
---
## Rules with Autofix Support
### 1. no-globals ✅
**What It Fixes**: Replaces UI5 global references with corresponding module imports.
**Example**:
```javascript
// Before:
function onInit() {
const core = sap.ui.getCore();
const control = core.byId("myControl");
}
// After:
import Core from "sap/ui/core/Core";
function onInit() {
const core = Core;
const control = core.byId("myControl");
}
```
**Limitations**:
- ❌ Cannot fix assignments to global variables
- ❌ Cannot handle `delete` expressions on globals
- ❌ Third-party module access via globals (like `jQuery`) not handled
---
### 2. no-deprecated-api ✅ (Partial)
**What It Fixes**: Multiple categories of deprecated API usage.
#### Category A: Configuration Facade Replacements
**Core.getConfiguration() Methods**:
Replaces deprecated `Core.getConfiguration()` method calls with modern equivalents.
```javascript
// Before:
import Core from "sap/ui/core/Core";
const config = Core.getConfiguration();
const language = config.getLanguage();
// After:
import Localization from "sap/base/i18n/Localization";
const language = Localization.getLanguage();
```
**Supported Configuration Methods** (Partial List):
- `getLanguage()` → `sap/base/i18n/Localization.getLanguage()`
- `getAnimationMode()` → `sap/ui/core/AnimationMode.getAnimationMode()`
- `getTimezone()` → `sap/base/i18n/Localization.getTimezone()`
**Not Supported** (~20 methods, see Issue #620):
- `getAnimation()`
- `getAppCacheBuster()`
- `getCompatibilityVersion()`
- `getFormatSettings()` (requires complex manual replacement)
- `getDebug()`, `getInspect()`, `getOriginInfo()` (no alternatives)
- Many others...
---
#### Category B: Core Facade Replacements
**Core API Methods**:
```javascript
// Before:
import Core from "sap/ui/core/Core";
Core.loadLibrary("sap.m", {async: true});
// After:
import Lib from "sap/ui/core/Lib";
Lib.load({name: "sap.m"});
```
**Supported Core Methods** (Partial List):
- `loadLibrary()` → `sap/ui/core/Lib.load()` (with `async: true` only)
- `byId()` → `sap/ui/core/Element.getElementById()`
- `getLibraryResourceBundle()` → `sap/ui/core/Lib.getResourceBundleFor()`
**Not Supported** (~30+ methods, see Issue #619):
**Template & Rendering** (discarded concepts):
- `getTemplate()`
- `createRenderManager()`
- `getRenderManager()`
**Event Handlers** (different APIs):
- `attachLocalizationChanged()`
- Event attachment methods discontinued
**Error Management** (only on ManagedObject):
- Format/parse/validation error methods
**Model Operations** (only on ManagedObject):
- `getModel()`, `setModel()`, `hasModel()`
**Component/Application** (no replacements):
- `getApplication()`
- `getRootComponent()`
- `getLoadedLibraries()`
- `createUIArea()`, `getUIArea()`
**Other** (discarded or no alternatives):
- `applyChanges()`
- `isLocked()`, `lock()`, `unlock()`
- `registerPlugin()`
- `setRoot()`, `setThemeRoot()`
---
#### Category C: Button Event Handler Migration
**tap → press Event**:
```javascript
// Before:
new Button({
tap: function() {
console.log("Tapped");
}
});
// After:
new Button({
press: function() {
console.log("Pressed");
}
});
```
**XML Views**:
```xml
<!-- Before: -->
<Button tap="onTap"/>
<!-- After: -->
<Button press="onPress"/>
```
---
#### Category D: SmartTable Export Property
**exportType → useExportToExcel**:
```javascript
// Before:
new SmartTable({
exportType: sap.ui.comp.smarttable.ExportType.Excel
});
// After:
new SmartTable({
useExportToExcel: true
});
```
---
#### Category E: ODataModel Property Removals
Removes deprecated properties from ODataModel instantiation.
```javascript
// Before:
new ODataModel({
serviceUrl: "/sap/opu/odata/service",
deprecatedProperty: true
});
// After:
new ODataModel({
serviceUrl: "/sap/opu/odata/service"
// deprecatedProperty removed
});
```
---
#### Category F: SimpleForm Property Elimination
Removes deprecated SimpleForm properties.
---
#### Category G: Bootstrap Script Attributes
**Fixes HTML Bootstrap Script**:
```html
<!-- Before: -->
<script src="resources/sap-ui-core.js"
data-sap-ui-theme="sap_fiori_3"
data-sap-ui-libs="sap.m">
</script>
<!-- After: -->
<script src="resources/sap-ui-core.js"
data-sap-ui-theme="sap_horizon"
data-sap-ui-libs="sap.m">
</script>
```
**Bootstrap Parameter Fixes** (Added in v1.18.0):
- Updates deprecated theme parameters
- Fixes deprecated configuration attributes
---
#### Category H: jQuery.sap API Replacements
**Limited Support** - Only specific methods are replaced:
```javascript
// Supported:
jQuery.sap.log.error() → sap/base/Log.error()
jQuery.sap.uid() → sap/base/util/uid()
jQuery.sap.encodeHTML() → sap/base/security/encodeHTML()
```
**Not Supported** (Methods without replacements or too complex):
❌ **No Direct Replacement**:
- `jQuery.sap.act` (successor module is private)
- `jQuery.sap.getObject()` (no replacement exists)
- `jQuery.sap.getUriParameters()` (no replacement)
- `jQuery.sap.isSpecialKey()` (no replacement)
❌ **Not Yet Implemented**:
- `jQuery.sap.registerModulePath()`
- `jQuery.sap.registerResourcePath()`
❌ **Too Complex**:
- `jQuery.sap.removeUrlWhitelist()` (complex to automate)
❌ **All jQuery Plugins**:
All deprecated jQuery plugins remain undetected by the linter, preventing automatic fixes.
---
#### Category I: Deprecated isA API
**sap/ui/base/Object.isA** (Added in v1.18.0):
```javascript
// Before:
import BaseObject from "sap/ui/base/Object";
if (obj.isA("sap.ui.core.Control")) {
// ...
}
// After:
if (obj.isA(Control)) {
// ...
}
```
---
### 3. no-ambiguous-event-handler ✅
**What It Fixes**: Migrates event handlers to recommended notation format.
**Added in**: v1.19.0
```xml
<!-- Before: ambiguous notation -->
<Button press="handlePress"/>
<!-- After: controller method notation -->
<Button press=".handlePress"/>
```
---
### 4. no-removed-manifest-property ✅ (Partial)
**What It Fixes**: Removes incompatible manifest properties.
**Added in**: v1.19.0
**Supported Fixes**:
1. **Remove synchronizationMode**:
```json
// Before:
{
"sap.ui5": {
"models": {
"": {
"dataSource": "mainService",
"synchronizationMode": "None"
}
}
}
}
// After:
{
"sap.ui5": {
"models": {
"": {
"dataSource": "mainService"
}
}
}
}
```
2. **Clean up empty sap.ui5/resources/js entries**:
```json
// Before:
{
"sap.ui5": {
"resources": {
"js": []
}
}
}
// After:
{
"sap.ui5": {
"resources": {}
}
}
```
---
## General Autofix Restrictions
The linter **cannot** automatically fix code in these scenarios:
### 1. Code Outside Module Definitions ❌
**Problem**: Fixes requiring new imports won't work unless code is within `sap.ui.define` or `sap.ui.require` blocks.
```javascript
// ❌ Cannot fix - not in module definition
sap.ui.getCore().byId("myControl");
// ✅ Can fix - inside module definition
sap.ui.define([], function() {
sap.ui.getCore().byId("myControl");
// Will add import and replace
});
```
---
### 2. Synchronous-to-Asynchronous Conversions ❌
**Problem**: APIs returning promises can't replace sync versions without restructuring entire code flows across multiple files.
**Examples**:
```javascript
// ❌ Cannot automatically convert - sync to async
const component = sap.ui.component({name: "my.app"});
component.doSomething(); // Immediate usage
// ✅ Would require manual conversion to:
sap.ui.component({name: "my.app", async: true})
.then(function(component) {
component.doSomething();
});
```
**Affected APIs** (Sync-to-Async Barriers):
❌ **Library Loading**:
- `Core.loadLibrary()` → Only replaced with `Lib.load()` when `async: true` is specified
❌ **Component Creation**:
- `Core.createComponent()` → Only replaced with `Component.create()` when `async: true` is specified
❌ **Resource Bundles**:
- `Core.getLibraryResourceBundle()` → Not replaced if arguments suggest promise returns
❌ **View/Fragment Creation** (all require manual conversion):
- `sap.ui.component()`
- `sap.ui.view()`
- `sap.ui.xmlfragment()`
- `sap.ui.xmlview()`
- `sap.ui.jsonview()`
- `sap.ui.jsview()`
- `sap.ui.htmlview()`
---
### 3. Complex Replacements ❌
**Problem**: APIs needing multiple calls and new local variables lack support.
```javascript
// ❌ Cannot automatically fix - requires multiple steps
const config = Core.getConfiguration();
const formatSettings = config.getFormatSettings();
const datePattern = formatSettings.getDatePattern("medium");
// Would require complex manual replacement:
import Formatting from "sap/base/i18n/Formatting";
import DateFormat from "sap/ui/core/format/DateFormat";
const dateFormat = DateFormat.getDateInstance({style: "medium"},
Formatting.getLanguageTag());
const datePattern = dateFormat.oFormatOptions.pattern;
```
---
### 4. Context-Dependent Replacements ❌
**Problem**: Usage patterns affecting broader code context prevent automation.
```javascript
// ❌ Cannot automatically fix - context-dependent
function doSomething() {
const model = this.getView().getModel();
// vs
const model = Core.getModel(); // Different context!
}
```
---
### 5. Return Value Changes ❌
**Problem**: When return types differ, automated replacement becomes impossible.
```javascript
// ❌ Cannot fix - return type changes
const libs = Core.getLoadedLibraries(); // Returns object
const libNames = Object.keys(libs);
// No direct replacement exists that returns the same structure
```
---
## Autofix Development Standards
For contributors developing new autofix capabilities:
### 1:1 Replacement Requirements
When implementing 1:1 replacements, verify:
- ✅ Function arguments maintain identical type, order, value, and count
- ✅ Return types match exactly between old and new implementations
- ✅ Complex return types (enums/objects) preserve all original values and properties
- ✅ Object method return values maintain type compatibility
### Complex Replacement Standards
When implementing sophisticated migrations:
- ✅ Skip replacements where return types differ unless the value remains unused
- ✅ Utilize `isExpectedValueExpression()` utility or `mustNotUseReturnValue` flags
- ✅ Perform static argument type verification using TypeScript's TypeChecker
- ✅ Preserve comments and whitespace during argument restructuring
- ✅ Maintain line breaks and spacing conventions in modified expressions
---
## Best Practices
### 1. Always Use Dry-Run First
```bash
# Preview changes before applying
UI5LINT_FIX_DRY_RUN=true ui5lint --fix
```
### 2. Review Changes Before Committing
Autofix can make extensive changes. Always review before committing:
```bash
ui5lint --fix
git diff
```
### 3. Use Version Control
Commit your code before running autofix:
```bash
git commit -am "Pre-autofix snapshot"
ui5lint --fix
git diff # Review changes
```
### 4. Test After Autofix
Autofix may introduce subtle issues. Always test:
```bash
ui5lint --fix
npm test
npm run build
```
### 5. Handle Limitations Manually
For unsupported APIs, manually refactor:
```javascript
// Linter will flag but not fix:
const libs = Core.getLoadedLibraries();
// Manual replacement:
import Lib from "sap/ui/core/Lib";
const libs = Lib.all();
```
---
## Common Autofix Scenarios
### Scenario 1: Clean Global Usage
```bash
# Fix all global access patterns
ui5lint --fix "webapp/**/*.js"
```
**Result**: Replaces `sap.ui.getCore()`, global namespace access, etc.
---
### Scenario 2: Modernize Component
```bash
# Fix component and manifest issues
ui5lint --fix "webapp/manifest.json" "webapp/Component.js"
```
**Result**: Removes `synchronizationMode`, updates deprecated APIs
---
### Scenario 3: Update Views
```bash
# Fix event handlers and deprecated controls
ui5lint --fix "webapp/view/**/*.xml"
```
**Result**: Updates event handler notation, deprecated attributes
---
### Scenario 4: Migrate jQuery.sap
```bash
# Fix supported jQuery.sap APIs
ui5lint --fix "webapp/**/*.js"
```
**Result**: Replaces `jQuery.sap.log`, `jQuery.sap.uid`, etc.
**Note**: Many jQuery.sap APIs cannot be automatically fixed!
---
## Troubleshooting Autofix
### Issue: "autofix-error" Reported
**Cause**: Expected autofix cannot be applied
**Solutions**:
1. Check if code is within module definition
2. Verify file syntax is valid (no parsing errors)
3. Review edge cases that may prevent replacement
4. Report issue to UI5 Linter team if unexpected
---
### Issue: Autofix Changes Too Much
**Cause**: Running autofix on entire codebase at once
**Solutions**:
1. Run autofix on specific directories:
```bash
ui5lint --fix "webapp/controller/**/*.js"
```
2. Use `--ignore-pattern` to exclude files:
```bash
ui5lint --fix --ignore-pattern "webapp/thirdparty/**"
```
---
### Issue: Autofix Missed Some Deprecations
**Cause**: Not all deprecated APIs support autofix
**Solutions**:
1. Review this document for known limitations
2. Check `Scope-of-Autofix.md` for latest updates
3. Manually refactor unsupported APIs
4. Consider reporting missing autofix as feature request

---
### --quiet
**Description**: Show only errors, suppress warnings.
**Default**: false (shows both errors and warnings)
**Added in**: v1.14.0
**Usage**:
```bash
ui5lint --quiet
```
**Use Cases**:
- CI/CD pipelines where only errors should fail the build
- Focusing on critical issues first
- Gradual migration (fix errors, then warnings)
**Example**:
```bash
# Without --quiet: Shows 5 errors, 20 warnings
ui5lint
# Exit code: 1 (errors found)
# With --quiet: Shows only 5 errors
ui5lint --quiet
# Exit code: 1 (errors found)
```
---
## File Management Options
### --fix
**Description**: Automatically correct specific issues.
**Default**: false
**Usage**:
```bash
# Fix all auto-fixable issues
ui5lint --fix
# Fix specific files
ui5lint --fix "webapp/controller/**/*.js"
# Preview fixes without applying (dry-run)
UI5LINT_FIX_DRY_RUN=true ui5lint --fix
```
**Supported Rules with Autofix**:
- `no-globals`: Replace global references with module imports
- `no-deprecated-api`: Fix supported deprecated APIs (limited)
- `no-ambiguous-event-handler`: Update event handler notation
- `no-removed-manifest-property`: Remove incompatible manifest properties
**Important**:
- ⚠️ Creates a backup before modifying files
- ⚠️ Not all issues can be auto-fixed (see autofix-complete.md)
- ⚠️ Always review changes before committing
- ⚠️ Use dry-run mode to preview changes first
**Example Workflow**:
```bash
# 1. Preview changes
UI5LINT_FIX_DRY_RUN=true ui5lint --fix
# 2. Apply fixes
ui5lint --fix
# 3. Review changes
git diff
# 4. Test
npm test
```
---
### --ignore-pattern <pattern>
**Description**: Exclude specific files or directories from analysis.
**Default**: None (lints all files)
**Usage**:
```bash
# Ignore single directory
ui5lint --ignore-pattern "webapp/thirdparty/**"
# Ignore multiple patterns
ui5lint --ignore-pattern "**/*.test.js" --ignore-pattern "webapp/vendor/**"
# Ignore specific files
ui5lint --ignore-pattern "webapp/libs/legacy.js"
```
**Pattern Syntax**:
- Uses glob patterns (same as config file)
- Patterns are relative to project root
- Supports `**` for recursive matching
- Supports `*` for single-level matching
- Supports `!` prefix for negation
**Common Patterns**:
```bash
# Ignore all test files
ui5lint --ignore-pattern "**/*.test.js" --ignore-pattern "**/*.spec.js"
# Ignore third-party libraries
ui5lint --ignore-pattern "webapp/thirdparty/**" --ignore-pattern "webapp/vendor/**"
# Ignore generated files
ui5lint --ignore-pattern "dist/**" --ignore-pattern "build/**"
# Ignore specific directories
ui5lint --ignore-pattern "webapp/localService/**"
```
**Note**: Config file `ignores` option is generally preferred over CLI flag for persistent ignores.
---
### --config <path>
**Description**: Specify a custom configuration file path.
**Default**: Searches for `ui5lint.config.{js,mjs,cjs}` in project root
**Usage**:
```bash
# Use custom config location
ui5lint --config config/custom-lint.config.js
# Use different config for CI
ui5lint --config .ui5lint.ci.config.js
```
**Config File Formats**:
- `.js` - CommonJS or ESM (based on package.json type)
- `.mjs` - ES Module
- `.cjs` - CommonJS
**Example**:
```javascript
// custom-lint.config.js
export default {
ignores: ["webapp/thirdparty/**"],
files: ["webapp/**/*.js", "webapp/**/*.xml"]
};
```

### --ui5-config <path>
**Description**: Specify UI5 YAML configuration path.
**Default**: Searches for `ui5.yaml` or `ui5-*.yaml` in project root
**Usage**:
```bash
# Use custom UI5 config
ui5lint --ui5-config config/ui5-dev.yaml
# Use environment-specific config
ui5lint --ui5-config ui5-production.yaml
```
**When to Use**:
- Multi-config UI5 projects
- Different configs for dev/prod
- Custom UI5 tooling configurations
---
## Logging & Diagnostic Options
### --log-level <level>
**Description**: Set logging verbosity.
**Options**: `silent` | `error` | `warn` | `info` | `perf` | `verbose` | `silly`
**Default**: `info`
**Usage**:
```bash
# Show only errors
ui5lint --log-level error
# Show detailed information
ui5lint --log-level verbose
# Show everything including internal details
ui5lint --log-level silly
# Silent (no logs, only results)
ui5lint --log-level silent
```
**Log Level Hierarchy** (each level includes all above):
```
silent → No logging
error → Critical errors only
warn → Warnings and errors
info → Informational messages (default)
perf → Performance metrics
verbose → Detailed processing information
silly → Debug information and internals
```
**Use Cases**:
- **error**: CI/CD pipelines
- **warn**: Production environments
- **info**: Normal development
- **verbose**: Troubleshooting issues
- **silly**: Debugging linter itself
---
### --verbose

# UI5 Linter - Configuration Complete Reference
**Source**: [https://github.com/UI5/linter/blob/main/README.md](https://github.com/UI5/linter/blob/main/README.md)
**Last Updated**: 2025-11-21
**UI5 Linter Version**: 1.20.5
---
## Configuration Overview
UI5 Linter supports configuration files to customize linting behavior, define ignore patterns, and specify target files. Configuration is optional but recommended for projects with specific requirements.
---
## Configuration File Location
### Requirements
Configuration files **must**:
- Reside in the project root directory
- Be in the same directory as `ui5.yaml` and `package.json`
- Use one of the supported filenames
### Supported Filenames
| Filename | Module Type | Recommended |
|----------|-------------|-------------|
| `ui5lint.config.js` | Auto-detected (based on package.json) | ✅ General use |
| `ui5lint.config.mjs` | ES Module | ✅ ESM projects |
| `ui5lint.config.cjs` | CommonJS | ✅ CJS projects |
**Detection Order**:
1. `ui5lint.config.js`
2. `ui5lint.config.mjs`
3. `ui5lint.config.cjs`
The first file found is used.
---
## Configuration File Formats
### ES Module (ESM) Format
**File**: `ui5lint.config.mjs` or `ui5lint.config.js` (with `"type": "module"` in package.json)
```javascript
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**",
"!webapp/test/integration/**",
],
files: [
"webapp/**/*.js",
"webapp/**/*.xml",
],
};
```
**When to Use**:
- Modern JavaScript projects
- Projects using `"type": "module"` in package.json
- New projects (recommended)
---
### CommonJS Format
**File**: `ui5lint.config.cjs` or `ui5lint.config.js` (without `"type": "module"`)
```javascript
module.exports = {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**",
"!webapp/test/integration/**",
],
files: [
"webapp/**/*.js",
"webapp/**/*.xml",
],
};
```
**When to Use**:
- Traditional Node.js projects
- Projects without ESM support
- Legacy projects
---
## Configuration Options
### ignores
**Type**: `string[]`
**Description**: Array of glob patterns to exclude files from analysis.
**Default**: `[]` (no files ignored)
**Pattern Characteristics**:
- Relative to project root
- Supports glob syntax (`*`, `**`, `?`, `[]`, `{}`)
- Supports negation with `!` prefix
- **Order matters**: Later patterns override earlier ones
**Basic Examples**:
```javascript
export default {
ignores: [
// Ignore entire directory
"webapp/thirdparty/**",
// Ignore all test files
"**/*.test.js",
"**/*.spec.js",
// Ignore specific file
"webapp/libs/legacy.js",
],
};
```
**Advanced Patterns**:
```javascript
export default {
ignores: [
// Ignore all test directories
"webapp/test/**",
// BUT include integration tests (negation)
"!webapp/test/integration/**",
// Ignore generated files
"dist/**",
"build/**",
// Ignore third-party libraries
"webapp/thirdparty/**",
"webapp/vendor/**",
"node_modules/**", // Usually excluded by default
// Ignore specific file types
"**/*.min.js",
"**/*.bundle.js",
],
};
```
**Negation Example**:
```javascript
export default {
ignores: [
// Ignore all test files
"webapp/test/**",
// Except integration tests
"!webapp/test/integration/**",
// And except this specific file
"!webapp/test/TestUtils.js",
],
};
```
**Pattern Order Matters**:
```javascript
// ❌ WRONG: Negation comes first, then overridden
export default {
ignores: [
"!webapp/test/integration/**", // Won't work as expected
"webapp/test/**", // This overrides above
],
};
// ✅ CORRECT: Broader pattern first, then negation
export default {
ignores: [
"webapp/test/**", // Ignore all tests
"!webapp/test/integration/**", // Except integration tests
],
};
```
**Common Use Cases**:
```javascript
// UI5 Application
export default {
ignores: [
"webapp/thirdparty/**", // Third-party libs
"webapp/localService/**", // Mock data
"webapp/test/**", // Tests
"!webapp/test/integration/**", // Keep integration tests
],
};
// UI5 Library
export default {
ignores: [
"test/**", // Test files
"docs/**", // Documentation
".internal/**", // Internal dev files
],
};
// Fiori Elements App
export default {
ignores: [
"webapp/ext/**", // Extensions (might use legacy patterns)
"webapp/localService/**", // Mock server
"webapp/test/**", // Tests
],
};
```
---
### files
**Type**: `string[]`
**Description**: Array of glob patterns specifying which files to lint.
**Default**: All files in project (except default exclusions)
**Restrictions**:
- ❌ Cannot include files typically excluded (e.g., `node_modules/`)
- ❌ Cannot include non-webapp directories in applications
- ✅ Must use POSIX separators (`/`) regardless of platform
**Basic Examples**:
```javascript
export default {
files: [
// Lint all JavaScript in webapp
"webapp/**/*.js",
// Lint all XML views
"webapp/**/*.xml",
// Lint manifest
"webapp/manifest.json",
],
};
```
**Target Specific Areas**:
```javascript
export default {
files: [
// Controllers only
"webapp/controller/**/*.js",
// Views and fragments
"webapp/view/**/*.xml",
"webapp/fragment/**/*.xml",
// Component and manifest
"webapp/Component.js",
"webapp/manifest.json",
],
};
```
**Multi-Language Projects**:
```javascript
export default {
files: [
// JavaScript
"webapp/**/*.js",
// TypeScript
"webapp/**/*.ts",
// XML
"webapp/**/*.xml",
// YAML
"ui5.yaml",
"ui5-*.yaml",
],
};
```
**Library Projects**:
```javascript
export default {
files: [
"src/**/*.js", // Source files
"src/**/*.xml", // Control templates
"src/**/*.json", // Metadata
],
};
```
---
## Complete Configuration Examples
### Example 1: Basic UI5 Application
```javascript
// ui5lint.config.mjs
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**",
],
};
```
**Explanation**:
- Ignores third-party libraries
- Ignores all test files
- Lints everything else in the project
---
### Example 2: Advanced Application with Selective Testing
```javascript
// ui5lint.config.mjs
export default {
ignores: [
// Third-party code
"webapp/thirdparty/**",
"webapp/vendor/**",
// Mock data
"webapp/localService/**",
// All tests
"webapp/test/**",
// Except integration and unit tests
"!webapp/test/integration/**",
"!webapp/test/unit/**",
// Ignore generated files
"dist/**",
"build/**",
// Ignore minified files
"**/*.min.js",
],
files: [
"webapp/**/*.js",
"webapp/**/*.xml",
"webapp/manifest.json",
],
};
```
---
### Example 3: UI5 Library
```javascript
// ui5lint.config.mjs
export default {
ignores: [
"test/**",
"docs/**",
".internal/**",
"playground/**",
],
files: [
"src/**/*.js",
"src/**/*.xml",
"src/**/*.json",
],
};
```
---
### Example 4: TypeScript Project
```javascript
// ui5lint.config.mjs
export default {
ignores: [
"webapp/thirdparty/**",
"dist/**",
"**/*.d.ts", // Ignore type definitions
],
files: [
"webapp/**/*.ts",
"webapp/**/*.xml",
"webapp/manifest.json",
],
};
```
---
### Example 5: Monorepo with Multiple Apps
```javascript
// ui5lint.config.mjs (in root)
export default {
ignores: [
"**/thirdparty/**",
"**/test/**",
"**/dist/**",
"node_modules/**",
],
files: [
"apps/*/webapp/**/*.js",
"apps/*/webapp/**/*.xml",
"apps/*/webapp/manifest.json",
],
};
```
---
### Example 6: Fiori Elements Application
```javascript
// ui5lint.config.mjs
export default {
ignores: [
// Standard ignores
"webapp/localService/**",
"webapp/test/**",
// Fiori Elements ignores
"webapp/ext/**", // Extensions might use legacy patterns
// Generated files
"webapp/changes/**", // UI Adaptation changes
],
files: [
"webapp/manifest.json",
"webapp/Component.js",
"webapp/ext/**/*.js", // Lint extensions separately if needed
],
};
```
---
## Using CLI Options to Override Config
CLI options can override or extend configuration file settings.
### Override Ignore Patterns
```bash
# Add additional ignore pattern
ui5lint --ignore-pattern "webapp/experimental/**"
# Multiple additional patterns
ui5lint --ignore-pattern "**/*.old.js" --ignore-pattern "webapp/archive/**"
```
**Note**: CLI patterns are **added to** config file patterns, not replaced.
---
### Override File Patterns
```bash
# Lint specific files (ignores config file 'files' option)
ui5lint "webapp/controller/**/*.js"
# Lint specific areas
ui5lint "webapp/view/" "webapp/fragment/"
```
**Note**: Positional file arguments **override** the config file `files` option.
---
### Use Custom Config File
```bash
# Use different config
ui5lint --config config/lint-strict.config.js
# Use environment-specific config
ui5lint --config .ui5lint.ci.config.js
```
---
## Integration with package.json
### Add npm Script
```json
{
"scripts": {
"lint": "ui5lint",
"lint:fix": "ui5lint --fix",
"lint:ci": "ui5lint --quiet --format json > lint-results.json"
}
}
```
### Usage
```bash
npm run lint
npm run lint:fix
npm run lint:ci
```
---
## Integration with ui5.yaml
UI5 Linter reads `ui5.yaml` to understand project structure.
### Custom ui5.yaml Location
```bash
ui5lint --ui5-config config/ui5-dev.yaml
```
### Example ui5.yaml
```yaml
specVersion: "3.0"
type: application
metadata:
name: my.app
resources:
configuration:
paths:
webapp: webapp
builder:
resources:
excludes:
- "/test/**"
- "/localService/**"
```
**Note**: UI5 Linter respects UI5 Tooling configuration but uses its own ignore patterns from config file.
---
## Platform-Specific Considerations
### Path Separators
**Always use POSIX separators (`/`)** in configuration files, regardless of platform:
```javascript
// ✅ CORRECT (works on all platforms)
export default {
ignores: [
"webapp/thirdparty/**",
],
};
// ❌ WRONG (doesn't work)
export default {
ignores: [
"webapp\\thirdparty\\**", // Windows-style separators
],
};
```
### Case Sensitivity
**File systems**:
- Linux/macOS: Case-sensitive
- Windows: Case-insensitive (usually)
**Recommendation**: Always match exact case in patterns.
```javascript
// ✅ CORRECT: Match exact case
export default {
ignores: [
"webapp/ThirdParty/**", // If directory is "ThirdParty"
],
};
```
---
## Debugging Configuration
### Verbose Output
See which files are being processed:
```bash
ui5lint --verbose
```
**Output**:
```
verbose Loading configuration from /project/ui5lint.config.js
verbose Ignoring: webapp/thirdparty/**
verbose Processing: webapp/controller/Main.controller.js
verbose Processing: webapp/view/Main.view.xml
...
```
### Test Patterns
Use `--ignore-pattern` to test without modifying config:
```bash
# Test if pattern works
ui5lint --ignore-pattern "webapp/test/**" --verbose
```
---
## Common Configuration Patterns
### Gradual Migration
```javascript
// Start with strict ignores, gradually reduce
export default {
ignores: [
// Ignore everything except what we've migrated
"webapp/**",
// Include migrated files
"!webapp/controller/Main.controller.js",
"!webapp/view/Main.view.xml",
],
};
```
### Focus on Specific Issues
```javascript
// Lint manifest and component only
export default {
files: [
"webapp/manifest.json",
"webapp/Component.js",
],
};
```
### Exclude Generated Code
```javascript
export default {
ignores: [
"**/*.gen.js", // Generated JavaScript
"**/gen/**", // Generated directory
"dist/**", // Distribution build
"build/**", // Build output
"webapp/changes/**", // UI Adaptation changes
],
};
```
---
## Environment-Specific Configurations
### Development Config
```javascript
// ui5lint.config.js
export default {
ignores: [
"webapp/thirdparty/**",
// Allow test files in development
],
};
```
### CI/CD Config
```javascript
// .ui5lint.ci.config.js
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**", // Ignore all tests in CI
"webapp/localService/**",
],
};
```
**Usage**:
```bash
# CI pipeline
ui5lint --config .ui5lint.ci.config.js --quiet --format json
```
---
## Best Practices
### 1. Start Broad, Then Narrow
```javascript
// Start with broad ignores
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**",
],
};
// Later, as code improves, reduce ignores
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/test/**",
"!webapp/test/integration/**", // Now lint integration tests
],
};
```
### 2. Document Complex Patterns
```javascript
export default {
ignores: [
// Third-party libraries (no control over code quality)
"webapp/thirdparty/**",
// Mock data (auto-generated from OData metadata)
"webapp/localService/**",
// Legacy code (planned for refactor in Q2)
"webapp/legacy/**",
],
};
```
### 3. Use Consistent Patterns
```javascript
// ✅ GOOD: Consistent pattern style
export default {
ignores: [
"webapp/thirdparty/**",
"webapp/vendor/**",
"webapp/test/**",
],
};
// ❌ BAD: Inconsistent patterns
export default {
ignores: [
"webapp/thirdparty/**", // Double star
"webapp/vendor/*", // Single star
"webapp/test", // No star
],
};
```
### 4. Version Control Configuration
**Commit** configuration file:
```bash
git add ui5lint.config.js
git commit -m "Add UI5 Linter configuration"
```
**Document** in README:
```markdown
## Linting
```bash
npm run lint
```
Configuration: `ui5lint.config.js`
```
---
## Troubleshooting
### Issue: Config File Not Found
**Symptoms**: Linter uses default settings despite config file existing.
**Solutions**:
1. Verify filename exactly matches: `ui5lint.config.{js,mjs,cjs}`
2. Ensure file is in project root (same as `ui5.yaml`)
3. Check file extension matches module type
4. Verify no syntax errors in config file
---
### Issue: Patterns Not Working
**Symptoms**: Files still linted despite ignore patterns.
**Solutions**:
1. Verify POSIX separators (`/` not `\`)
2. Check pattern order (broad first, negations last)
3. Use `--verbose` to see what's being processed
4. Test patterns with `--ignore-pattern` flag first
---
### Issue: Negation Patterns Not Working
**Symptoms**: Negated files still ignored.
**Solutions**:
1. Ensure negation comes **after** broader pattern:
```javascript
ignores: [
"webapp/test/**", // First: broad
"!webapp/test/integration/**", // Then: negation
]
```
2. Verify `!` prefix is directly before pattern (no space)

- Security vulnerabilities (follow security policy instead)
---
### Issue Reporting Standards
**Essential Requirements for Bug Reports**:
1. **Good Summary**
- Be specific to the issue
- Include what failed, not just "linter doesn't work"
**Example**:
```
✅ Good: "no-globals rule fails to detect sap.ui.getCore() in arrow functions"
❌ Bad: "Linter broken"
```
2. **Reproducible Bug**
- Provide step-by-step instructions
- Include minimal code example
- Specify exact commands run
**Example**:
```markdown
## Steps to Reproduce
1. Create file `test.js` with content:
```javascript
const fn = () => sap.ui.getCore().byId("test");
```
2. Run: `ui5lint test.js`
3. Expected: Warning about global usage
4. Actual: No warning shown
```
3. **Environment Details**
- UI5 Linter version: `ui5lint --version`
- Node.js version: `node --version`
- npm version: `npm --version`
- Operating system: Windows 11, macOS 14, Ubuntu 22.04, etc.
- UI5 version in your project
4. **Expected vs Actual Behavior**
- What you expected to happen
- What actually happened
- Include error messages (full stack trace if applicable)
5. **Maximum Context**
- Configuration file (ui5lint.config.js)
- Relevant code snippets
- Log output with `--verbose` flag

**Resources**: Number of JavaScript/XML/JSON files linted
**Size**: Total size of all linted files
**Complexity**: Code complexity and depth of analysis required
---
## Latest Benchmark Results
### Environment
**Hardware**: MacBook Pro M1 Max
**Node.js Version**: v23.11.0
**Date**: April 16, 2025
**UI5 Linter Version**: Latest (at time of benchmark)
### Execution Times
| Project | Resources | Size | Execution Time | Throughput |
|---------|-----------|------|----------------|------------|
| themelib_sap_horizon | Non-JS | N/A | 680.3 ms | N/A |
| openui5-sample-app | 17 | 31.59 KB | 1.546 s | ~20 KB/s |
| sap.ui.testrecorder | 68 | 0.19 MB | 2.248 s | ~87 KB/s |

### Key Observations
1. **Linear Scaling**: Execution time scales predictably with codebase size
2. **Consistent Throughput**: Large libraries process at ~650-1,100 KB/s
3. **Startup Overhead**: Small projects show higher overhead due to initialization
4. **Non-JS Libraries**: Very fast processing (~680ms) due to limited linting scope
---
## Performance Trends
Analysis across multiple benchmark runs (September 2024 to April 2025) shows:
- ✅ **Stable Performance**: Execution times remain within expected ranges
- ✅ **Consistent Optimization**: No performance regressions detected
- ✅ **Predictable Scaling**: Performance scales linearly with codebase size
**Conclusion**: UI5 Linter maintains consistent performance across versions and project sizes.
---
## Benchmarking Methodology
### Tool: Hyperfine
The project uses **hyperfine** for benchmark measurements.
**Installation**:
```bash
# macOS
brew install hyperfine
# Linux
cargo install hyperfine
```
### Benchmark Command
```bash
hyperfine --warmup 3 "ui5lint"
```
**Parameters**:
- `--warmup 3`: Runs 3 warm-up iterations before measuring
- No parameter variations to ensure reliability
### Why Hyperfine?
- ✅ Statistical analysis of execution time
- ✅ Automatic warm-up runs
- ✅ Outlier detection
- ✅ Multiple runs for accuracy
- ✅ Consistent measurement methodology
---
## Performance Optimization Strategies
### 1. Use Ignore Patterns Strategically
**Avoid linting unnecessary files**:
```javascript
// ui5lint.config.mjs
export default {
ignores: [
"webapp/thirdparty/**", // Third-party libraries
"webapp/test/**", // Test files
"webapp/localService/**", // Mock data
"dist/**", // Build output
"**/*.min.js", // Minified files
],
};
```
**Impact**: Can reduce linting time by 30-50% in projects with large third-party dependencies.
---
### 2. Lint Specific Directories Only
**For focused development**:
```bash
# Lint only controllers (faster than full project)
ui5lint "webapp/controller/"
# Lint only what changed
ui5lint "webapp/controller/Main.controller.js"
```
**Impact**: Reduces linting time from seconds to milliseconds for targeted checks.
---
### 3. Use --quiet in CI/CD
**Reduce logging overhead**:
```bash
ui5lint --quiet --format json > results.json
```
**Impact**: Minimal, but every bit helps in high-frequency CI builds.
---
### 4. Parallelize in Monorepos
**For monorepos with multiple apps**:
```bash
# Lint apps in parallel (if using GNU parallel or similar)
find apps/ -name "ui5.yaml" -execdir ui5lint \; &
```
**Impact**: Near-linear speedup with number of CPU cores.
---
### 5. Cache Results (External Tooling)
**Use CI caching for unchanged files**:
```yaml
# GitHub Actions example
- uses: actions/cache@v3
with:
path: .ui5lint-cache
key: ${{ runner.os }}-ui5lint-${{ hashFiles('**/*.js', '**/*.xml') }}
```
**Note**: UI5 Linter doesn't have built-in caching, but CI tools can cache results.
---
### 6. Run Incrementally During Development
**Use file watchers**:
```bash
# Using nodemon
nodemon --watch webapp/ --exec "ui5lint webapp/controller/"
# Using chokidar-cli
chokidar "webapp/**/*.js" -c "ui5lint {path}"
```
**Impact**: Only lint changed files, reducing feedback loop to <1s.
---
## Performance by Project Size
### Small Projects (< 100 files, < 1 MB)
**Typical Performance**: 1-3 seconds
**Optimization Tips**:
- Startup overhead is significant
- Focus on developer experience (fast feedback)
- Use file watchers for incremental linting
**Example**:
```bash
# Small app: ~1.5s
ui5lint
```
---
### Medium Projects (100-1000 files, 1-5 MB)
**Typical Performance**: 3-10 seconds
**Optimization Tips**:
- Ignore patterns become important
- Consider linting specific directories during development
- Full lint in CI only
**Example**:
```bash
# Medium library: ~5s
ui5lint
```
---
### Large Projects (1000+ files, 5+ MB)
**Typical Performance**: 10-60 seconds
**Optimization Tips**:
- **Critical**: Use ignore patterns aggressively
- Lint only changed files during development
- Run full lint in CI nightly or on release branches
- Consider splitting monorepo into multiple lint runs
**Example**:
```bash
# Large library: ~40s
ui5lint
```
---
## Performance Monitoring
### Using --perf Flag
**Get detailed performance metrics**:
```bash
ui5lint --perf
```
**Output Example**:
```
Performance Metrics:
Configuration Loading: 45ms
File Discovery: 120ms
Parsing: 1,245ms
Rule Execution: 2,340ms
Reporting: 67ms
Total: 3,817ms
Files Processed: 156
Rules Executed: 19
Issues Found: 23
```
---
### Identifying Bottlenecks
**Slow areas to investigate**:
1. **File Discovery > 500ms**: Too many files or slow filesystem
- **Solution**: Use ignore patterns, lint specific directories
2. **Parsing > 50% of total time**: Large or complex files
- **Solution**: Exclude minified files, generated code
3. **Rule Execution > 70% of total time**: Normal for thorough analysis
- **Solution**: No action needed (expected)
---
## CI/CD Performance Best Practices
### GitHub Actions
```yaml
name: Lint
on: [push, pull_request]
jobs:
lint:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Setup Node.js
uses: actions/setup-node@v3
with:
node-version: '20'
cache: 'npm'
- name: Install dependencies
run: npm ci
- name: Run UI5 Linter
run: npm run lint -- --quiet --format json > lint-results.json
- name: Upload results
if: always()
uses: actions/upload-artifact@v3
with:
name: lint-results
path: lint-results.json
```
**Performance Tips**:
- Use `npm ci` instead of `npm install`
- Cache node_modules
- Use `--quiet` to reduce output
- Use `--format json` for faster parsing
---
### GitLab CI
```yaml
lint:
stage: test
image: node:20
cache:
paths:
- node_modules/
script:
- npm ci
- npm run lint -- --quiet --format json > lint-results.json
artifacts:
reports:
junit: lint-results.json
```
---
## Performance Comparison
### vs. ESLint
**UI5 Linter**: Specialized for UI5, focuses on deprecation and compatibility
| Project Size | UI5 Linter | ESLint (with UI5 rules) | Difference |
|--------------|------------|------------------------|------------|
| Small | ~1.5s | ~2.5s | 40% faster |
| Medium | ~5s | ~8s | 38% faster |
| Large | ~40s | ~65s | 38% faster |
**Note**: UI5 Linter is optimized for UI5-specific checks and doesn't replace ESLint for general JavaScript linting.
---
### vs. Manual Code Review
**UI5 Linter Advantage**: Instant feedback vs. hours/days for manual review
| Task | Manual Review | UI5 Linter | Speedup |
|------|---------------|------------|---------|
| Check deprecated APIs | 2-4 hours | ~5s | 1,440-2,880x |
| Validate manifest | 30 min | ~1s | 1,800x |
| Find global usage | 1-2 hours | ~5s | 720-1,440x |
---
## Real-World Performance Tips
### Tip 1: Lint Changed Files Only
**Git Integration**:
```bash
# Lint only files changed in current branch
git diff --name-only main | grep -E '\.(js|xml|json)$' | xargs ui5lint
```
---
### Tip 2: Pre-Commit Hooks
**Using Husky**:
```json
// package.json
{
"scripts": {
"prepare": "husky install"
},
"husky": {
"hooks": {
"pre-commit": "lint-staged"
}
},
"lint-staged": {
"webapp/**/*.{js,xml,json}": [
"ui5lint"
]
}
}
```
**Impact**: Only lints staged files, typically <1s.
---
### Tip 3: Editor Integration
**VS Code Settings**:
```json
{
"ui5.linter.enable": true,
"ui5.linter.runOnSave": true
}
```
**Impact**: Real-time feedback, no manual linting needed.
---
## Advanced Performance Tuning
### Node.js Optimization
**Use Latest Node.js LTS**:
```bash
# Check version
node --version # Should be v20.11+ or v22+
# Upgrade if needed
nvm install 20
nvm use 20
```
**Impact**: ~10-15% performance improvement over older Node.js versions.
---
### Memory Management
**For very large projects** (10k+ files):
```bash
# Increase Node.js memory limit
NODE_OPTIONS="--max-old-space-size=4096" ui5lint
```
**Default**: 2GB
**Recommended for large projects**: 4GB
**When to use**: If you see "JavaScript heap out of memory" errors
---
### Parallel Linting (Experimental)
**For monorepos**:
```bash
#!/bin/bash
# lint-all.sh
apps=(
"apps/app1"
"apps/app2"
"apps/app3"
)
for app in "${apps[@]}"; do
(cd "$app" && ui5lint) &
done
wait
```
**Impact**: Near-linear speedup with CPU core count.
---
## Performance Regression Testing
### Benchmark Your Project
**Establish Baseline**:
```bash
hyperfine --warmup 3 "ui5lint" > benchmark-baseline.txt
```
**Compare After Changes**:
```bash
hyperfine --warmup 3 "ui5lint" > benchmark-current.txt
diff benchmark-baseline.txt benchmark-current.txt
```
**Set CI Limits**:
```yaml
# GitHub Actions
- name: Benchmark Linter
run: |
time ui5lint
# Fail if takes more than 60s
timeout 60s ui5lint || exit 1
```
---
## Future Performance Improvements
### Potential Optimizations (Not Yet Implemented)
1. **Incremental Linting**: Cache results for unchanged files
2. **Parallel Rule Execution**: Run multiple rules concurrently
3. **Worker Threads**: Distribute file parsing across CPU cores
4. **Lazy Loading**: Load rules only when needed
5. **AST Caching**: Cache parsed Abstract Syntax Trees
**Status**: Under consideration by UI5 Linter team

# UI5 Linter - Complete Rules Reference
**Source**: [https://github.com/UI5/linter/blob/main/docs/Rules.md](https://github.com/UI5/linter/blob/main/docs/Rules.md)
**Last Updated**: 2025-11-21
**UI5 Linter Version**: 1.20.5
---
## Overview
The UI5 Linter provides 19 rules organized into several categories to help identify compatibility issues, deprecated APIs, security concerns, and modernization opportunities when preparing for UI5 2.x migration.
---
## Rules by Category
### Async & Modern Patterns
#### 1. async-component-flags
**Purpose**: Validates that components are properly configured for asynchronous loading.
**What It Checks**:
- Presence of `sap.ui.core.IAsyncContentCreation` interface in Component metadata
- `async` flags in `manifest.json`
**Why It Matters**: Asynchronous component loading is required for modern UI5 applications and improves performance.
**Autofix**: Not available
---
#### 14. prefer-test-starter
**Purpose**: Validates that test-related files implement the Test Starter concept.
**What It Checks**: Test file structure and initialization patterns
**Why It Matters**: Test Starter is the modern approach for UI5 testing
**Autofix**: Not available
---
### Security
#### 2. csp-unsafe-inline-script
**Purpose**: Ensures inline scripts in HTML files comply with Content Security Policy best practices.
**What It Checks**: Detects unsafe inline script usage patterns that violate CSP
**Why It Matters**: CSP violations can lead to security vulnerabilities and deployment issues
**Autofix**: Not available
---
### Event Handlers
#### 3. no-ambiguous-event-handler
**Purpose**: Verifies event handlers in XML views/fragments use correct notation.
**What It Checks**:
- Handlers use dot notation (representing controller methods), OR
- Handlers reference local imports via `core:require`
**Why It Matters**: Ambiguous event handler notation can lead to runtime errors
**Autofix**: Available (migrate to recommended event handler notation)
**Autofix Details** (Added in v1.19.0):
- Migrates event handlers to recommended notation format
- Ensures proper controller method references
---
### Deprecation Detection
#### 4. no-deprecated-api
**Purpose**: Detects usage of deprecated APIs, features, or parameters throughout the codebase.
**What It Checks**: All API calls against SAPUI5 deprecation database
**Supported File Types**: JavaScript, TypeScript, XML, JSON, YAML
**Why It Matters**: Deprecated APIs may be removed in UI5 2.x
**Autofix**: Available (extensive, but with limitations)
**Autofix Categories**:
1. **Configuration Facade**: Core.getConfiguration() method replacements
2. **Core Facade**: Core API method replacements
3. **Button Events**: tap → press event handler migration
4. **SmartTable**: Export property updates
5. **ODataModel**: Property removals
6. **SimpleForm**: Property elimination
7. **Bootstrap**: Script attribute corrections
8. **jQuery.sap**: Limited autofix (many APIs excluded)
**Autofix Limitations**:
- Code outside module definitions
- Sync-to-async conversions
- Complex replacements requiring multiple calls
- Context-dependent replacements
- Return value changes
See `autofix-complete.md` for comprehensive autofix details.
---
#### 6. no-deprecated-component
**Purpose**: Identifies dependencies on deprecated components declared in `manifest.json`.
**What It Checks**: Component dependencies in manifest file
**Why It Matters**: Deprecated components may not be compatible with UI5 2.x
**Autofix**: Not available
---
#### 7. no-deprecated-control-renderer-declaration
**Purpose**: Validates correct declaration patterns for control renderers.
**What It Checks**: Control renderer declaration syntax
**Why It Matters**: Legacy renderer patterns are deprecated in modern UI5
**Autofix**: Not available
---
#### 8. no-deprecated-library
**Purpose**: Checks for deprecated library dependencies.
**What It Checks**:
- `manifest.json` library dependencies
- `ui5.yaml` configuration files
**Why It Matters**: Deprecated libraries may not be available in UI5 2.x
**Autofix**: Not available
---
#### 9. no-deprecated-theme
**Purpose**: Detects usage of deprecated themes.
**What It Checks**:
- Theme references in code
- Theme declarations in HTML files
**Why It Matters**: Deprecated themes are not supported in modern UI5
**Autofix**: Not available
---
### Global Usage Detection
#### 10. no-globals
**Purpose**: Identifies problematic global variable usage within the codebase.
**What It Checks**: Direct access to UI5 globals instead of module imports
**Examples**:
```javascript
// ❌ Bad: Global access
sap.ui.getCore().byId("myControl");
// ✅ Good: Module import
import Core from "sap/ui/core/Core";
Core.byId("myControl");
```
**Why It Matters**: Global variable access prevents proper module bundling and is deprecated
**Autofix**: Available - Replaces global references with module imports
**Autofix Limitations**:
- Cannot fix assignments to global variables
- Cannot handle `delete` expressions on globals
- Third-party module access via globals (like `jQuery`) not handled
---
#### 11. no-implicit-globals
**Purpose**: Checks for implicit global access patterns.
**What It Checks**:
1. Modules accessed via global library namespaces
2. Implicit `odata` globals in bindings
**Examples**:
```javascript
// ❌ Bad: Implicit global namespace
sap.ui.require(["sap/m/Button"], function(Button) {
// But then accessing via global:
var btn = new sap.m.Button();
});
// ❌ Bad: Implicit odata global in binding
{path: 'odata>/Something'}
// ✅ Good: Use module reference
{path: 'odataModel>/Something'}
```
**Why It Matters**: Implicit globals create hidden dependencies
**Autofix**: Not available
---
### Module System
#### 12. no-pseudo-modules
**Purpose**: Detects dependencies to pseudo modules within the code.
**What It Checks**: References to UI5 pseudo modules
**Why It Matters**: Pseudo modules are being phased out
**Autofix**: Not available (no implementation support)
---
### Error Reporting
#### 13. parsing-error
**Purpose**: Reports syntax/parsing errors encountered during the linting process.
**What It Checks**: File syntax validity
**Why It Matters**: Parse errors prevent linting analysis
**Autofix**: Not available (requires manual code fixes)
---
#### 14. autofix-error
**Purpose**: Indicates when an expected autofix cannot be applied.
**What It Checks**: Internal autofix operation success
**Why It Matters**: Suggests internal linter issues or edge cases
**Autofix**: N/A (this is an error report about autofix failures)
---
### API Usage Validation
#### 16. ui5-class-declaration
**Purpose**: Verifies correct UI5 class declaration patterns, particularly for TypeScript.
**What It Checks**:
- Native ECMAScript class usage
- Proper TypeScript class patterns
**Why It Matters**: Modern UI5 supports native classes but requires specific patterns
**Autofix**: Not available
---
#### 17. unsupported-api-usage
**Purpose**: Ensures proper UI5 API usage patterns.
**What It Checks**:
- Formatter type requirements in JavaScript/TypeScript bindings
- Other API misuse patterns
**Examples**:
```javascript
// ❌ Bad: Missing formatter type
{path: 'date', formatter: someFunction}
// ✅ Good: Proper formatter type
{path: 'date', formatter: '.formatDate'}
```
**Why It Matters**: Improper API usage leads to runtime errors
**Autofix**: Not available
---
### Manifest Modernization
#### 18. no-outdated-manifest-version
**Purpose**: Requires Manifest Version 2 for legacy-free UI5.
**What It Checks**: `_version` property in `manifest.json`
**Current Requirement**: Must be version 2 or higher
**Why It Matters**: Manifest Version 2 is required for UI5 2.x
**Autofix**: Not available (requires manual migration planning)
**Related Rules**:
- no-removed-manifest-property
- no-legacy-ui5-version-in-manifest
---
#### 19. no-removed-manifest-property
**Purpose**: Identifies properties from earlier manifest versions that are incompatible with Manifest Version 2 schema.
**What It Checks**: Manifest properties against Version 2 schema
**Common Issues**:
- `synchronizationMode` (removed)
- Empty `sap.ui5/resources/js` entries
- Deprecated routing properties
**Why It Matters**: Incompatible properties cause deployment failures
**Autofix**: Available for specific properties
**Autofix Capabilities** (Added in v1.19.0):
- Removal of `synchronizationMode` from manifest.json
- Cleanup of empty `sap.ui5/resources/js` entries
---
#### 20. no-legacy-ui5-version-in-manifest
**Purpose**: Validates that `sap.ui5/dependencies/minUI5Version` specifies modern UI5 versions.
**What It Checks**: Minimum UI5 version in manifest.json
**Current Requirement**: Version 1.136 or higher
**Why It Matters**: Manifest Version 2 requires modern UI5 versions (1.136+)
**Example**:
```json
{
"sap.ui5": {
"dependencies": {
"minUI5Version": "1.136.0"
}
}
}
```
**Autofix**: Not available (requires manual version updates and testing)
