## About

# TypeScript Tooling

## **Priority: P1 (OPERATIONAL)**

## Implementation Guidelines

- **Compiler**: Use `tsc` for CI builds; `esbuild` or `ts-node` for development.
- **Linting**: Enforce `ESLint` with `@typescript-eslint/recommended`. Enable strict type checking.
- **Formatting**: Mandate `Prettier` via `lint-staged` and `.prettierrc`.
- **Testing**: Use `Vitest` (or `Jest`) for unit/integration testing. Target > 80% line coverage.
- **Builds**: Use `tsup` (library bundling) or `Vite` (web applications).
- **TypeScript Config**: Aim for `strict: true` long-term. For existing projects, migrate incrementally: start with `strictNullChecks`, then `noImplicitAny`, `strictFunctionTypes`. Do NOT flip `strict: true` in one step.
- **CI/CD**: Always run `tsc --noEmit` in build pipeline to catch type errors.
- **Error Suppression**: Favor `@ts-expect-error` over `@ts-ignore` for documented edge-cases.

## ESLint Configuration

Enable `@typescript-eslint/recommended` at minimum. When `strict: false` in tsconfig, `no-unsafe-*` rules may produce excessive noise — suppress selectively with `@ts-expect-error` rather than disabling globally.

See [reference](references/REFERENCE.md) for common linting issues (request typing, unused params, test mock typing) and tsconfig migration examples.

## Verification Workflow (Mandatory)

After editing any `.ts` / `.tsx` file:

1. Call `getDiagnostics` (typescript-lsp MCP tool) — surfaces type errors in real time.
2. Run `tsc --noEmit` in CI — catches project-wide errors LSP may miss.
3. Run `eslint --fix` — auto-fix formatting and lint violations.

> **Fallback when typescript-lsp MCP unconfigured**: run `tsc --noEmit` directly.

`getDiagnostics` fastest feedback loop. Use it before every commit on modified files. Use `getHover` to inspect inferred types, `getReferences` before renaming symbols.

## Anti-Patterns

- **No `@ts-ignore`**: Use `@ts-expect-error` — self-documents intent, fails if error disappears.
- **No `any` for request objects**: Import centralized interfaces from `src/common/interfaces/`.
- **No `eslint-disable` (global)**: Suppress per-line; fix root cause instead.
- **No atomic `strict: true` flip** on existing repos: migrate incrementally starting with `strictNullChecks`.
