Priority: P1 (OPERATIONAL)
Essential tooling for JavaScript development.
Implementation Guidelines
- Linting: ESLint (Rec + Prettier). Fix on save.
- Formatting: Prettier. Run on save/commit.
- Testing: Jest/Vitest. Co-locate tests. >80% cov.
- Build: Vite (Apps), Rollup (Libs).
- Pkg Manager: Sync versions (
npm/yarn/pnpm).
Anti-Patterns
- No Formatting Wars: Prettier rules.
- No Untested Code: TDD/Post-code tests.
- No Dirty Commits: Lint before push.

};
// .prettierrc
