TypeScript Config

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,

ESLint Setup

Fix linting errors with nr lint --fix. Do NOT add a separate lint:fix script.

For detailed configuration options: antfu-eslint-config

Git Hooks

{
  "simple-git-hooks": {
    "pre-commit": "pnpm i --frozen-lockfile --ignore-scripts --offline && npx lint-staged"
  },
  "lint-staged": { "*": "eslint --fix" },
  "scripts": { "prepare": "npx simple-git-hooks" }
}

Vitest Conventions

• Test files: foo.ts → foo.test.ts (same directory)
• Use describe/it API (not test)
• Use toMatchSnapshot for complex outputs
• Use toMatchFileSnapshot with explicit path for language-specific snapshots

pnpm Catalogs

Use named catalogs in pnpm-workspace.yaml for version management:

Avoid the default catalog. Catalog names can be adjusted per project needs.
