|
|
|
|
Priority levels and response times for Bulletproof React audit findings.
|
|
|
|
## Severity Levels
|
|
|
|
### Critical (P0)
|
|
**Fix immediately (within 24 hours)**
|
|
|
|
#### Criteria
|
|
- Security vulnerabilities (tokens in localStorage, XSS risks)
|
|
- Breaking architectural violations that prevent scalability
|
|
- No testing framework in production app
|
|
- TypeScript strict mode disabled with widespread `any` usage
|
|
|
|
#### Examples
|
|
- Authentication tokens stored in localStorage
|
|
- No error boundaries in production app
|
|
- Zero test coverage on critical paths
|
|
- Multiple cross-feature dependencies creating circular imports
|
|
|
|
#### Impact
|
|
- Security breaches possible
|
|
- Application instability
|
|
- Cannot safely refactor or add features
|
|
- Technical debt compounds rapidly
|
|
|

|
|
|
### High (P1)
|
|
**Fix this sprint (within 2 weeks)**
|
|
|
|
#### Criteria

|
- Major architectural misalignment with Bulletproof React
|
|
- No data fetching library (manual API state management)
|
|
- Test coverage < 80%
|
|
- Large components (> 400 LOC) with multiple responsibilities
|
|

|
|
- Scattered fetch calls throughout components
|
|
- No React Query/SWR for server state
|
|
- Components with 15+ props

|
|
|
|
#### Impact
|
|
- Difficult to maintain and extend
|
|

|
|
|
|
#### Impact

|
#### Criteria
|
|
- Minor deviations from Bulletproof React patterns
|
|
- Stylistic improvements
|
|
- Missing nice-to-have features

|
|
|
|
#### Examples

|
|
- Missing some recommended directories
|
|
- Test naming doesn't follow "should X when Y"

|
|
|
|
#### Impact
|
|
- Minimal impact on development
|
|
- Minor inconsistencies
|
|

|
|
