TypeScript Tooling

Priority: P1 (OPERATIONAL)

Essential tooling for TypeScript development and maintenance.

Implementation Guidelines

• Compiler: tsc for CI. ts-node/esbuild for dev.
• Lint: ESLint + @typescript-eslint. Strict type checking.
• Format: Prettier (on save + commit).
• Test: Jest/Vitest > 80% coverage.
• Build: tsup (libs), Vite/Webpack (apps).
• Check: tsc --noEmit in CI.

Anti-Patterns

• No Disable: Avoid // eslint-disable.
• No Skip: Avoid skipLibCheck: true if possible.
• No Ignore: Use @ts-expect-error > @ts-ignore.

Configuration

// tsconfig.json
{
  "compilerOptions": {
    "strict": true,
    "noImplicitReturns": true,
    "noUnusedLocals": true
  }
}
