# Build & Deployment Best Practices
## Build Process
### Running Builds
- Use `pnpm build` from project root for full build
- Monitor for React hooks warnings and fix them immediately
- Ensure all TypeScript errors are resolved before deployment
### Common Build Issues & Fixes
#### React Hooks Warnings
- Capture ref values in variables within useEffect cleanup
- Avoid accessing `.current` directly in cleanup functions
- Pattern for fixing ref cleanup warnings:
```typescript
useEffect(() => {
const currentRef = myRef.current;
return () => {
if (currentRef) {
currentRef.cleanup();
}
};
}, []);
```
#### Test Failures During Build
- Ensure all test mocks include required constants like `SESSION_MAX_AGE`
- Mock Next.js navigation hooks properly: `useParams`, `useRouter`, `useSearchParams`
- Remove unused imports and constants from test files
- Use literal values instead of imported constants when the constant isn't actually needed
### Test Execution
- Run `pnpm test` to execute all tests
- Use `pnpm test -- --run filename.test.tsx` for specific test files
- Fix test failures before merging code
- Ensure 100% test coverage for new components
### Performance Monitoring
- Monitor build times and optimize if necessary
- Watch for memory usage during builds
- Use proper caching strategies for faster rebuilds
### Deployment Checklist
1. All tests passing
2. Build completes without warnings
3. TypeScript compilation successful
4. No linter errors
5. Database migrations applied (if any)
6. Environment variables configured
### EKS Deployment Considerations
- Ensure latest code is deployed to all pods
- Monitor AWS RDS Performance Insights for database issues
- Verify environment-specific configurations
- Check pod health and resource usage
