Definitely Typed is the central repository of high-quality TypeScript type definitions (.d.ts files) for thousands of popular JavaScript packages without bundled types. Definitions are published to npm under the @types scope and validated by CI type-checking and linting.
Use cases
- add TypeScript types for a JavaScript npm package
- install @types definitions for a library
- fix type errors when using an untyped JS dependency
- contribute type definitions for a package I use
- find typings for express or react
When to choose
- you use TypeScript with npm packages that lack their own type declarations
- you want community-maintained, CI-validated typings installed via @types packages
When to avoid
- the library already ships its own TypeScript types
- you need types for a niche package not accepted into the repo
