Build, Validation, And Repo Layout

Common commands

• Install dependencies: yarn install
• Run tests: yarn test
• Run tests in CI mode: yarn test:ci
• Type check: yarn typecheck
• Lint source files: yarn lint
• Check formatting: yarn format:check
• Validate the main package: yarn validate
• Build the package: yarn build

Command notes

• yarn lint runs ESLint on src.
• yarn validate runs typecheck, tests, lint, and oxfmt checks for the main package.
• yarn build cleans dist/, transpiles source with Babel, and emits TypeScript declarations.

Repo layout

• src/: source code
• src/pure.ts: core logic without side effects
• src/index.ts: main entry point with auto-cleanup side effects
• examples/: example React Native apps
• website/: documentation site
• codemods/: codemod implementations and tests
