bashnpx tsc --noEmit --pretty npx tsc --noEmit --pretty --incremental false # Show all errors npm run build npx eslint . --ext .ts,.tsx,.js,.jsx
npx tsc --noEmit --pretty to get all type errorsFor each error:
| Error | Fix | |-------|-----| | implicitly has 'any' type | Add type annotation | | Object is possibly 'undefined' | Optional chaining ?. or null check | | Property does not exist | Add to interface or use optional ? | | Cannot find module | Check tsconfig paths, install package, or fix import path | | Type 'X' not assignable to 'Y' | Parse/convert type or fix the type | | Generic constraint | Add extends { ... } | | Hook called conditionally | Move hooks to top level | | 'await' outside async | Add async keyword |
DO:
DON'T:
| Level | Symptoms | Action | |-------|----------|--------| | CRITICAL | Build completely broken, no dev server | Fix immediately | | HIGH | Single file failing, new code type errors | Fix soon | | MEDIUM | Linter warnings, deprecated APIs | Fix when possible |
