TypeScript types for Bun

These are the type definitions for Bun's JavaScript runtime APIs.

Installation

Install the @types/bun npm package:

# yarn/npm/pnpm work too
# @types/bun is an ordinary npm package
bun add -D @types/bun

That's it! VS Code and TypeScript automatically load @types/* packages into your project, so the Bun global and all bun:* modules should be available immediately.

Contributing

The @types/bun package is a shim that loads bun-types. The bun-types package lives in the Bun repo under packages/bun-types. It is generated via ./scripts/bundle.ts.

To add a new file, add it under packages/bun-types. Then add a triple-slash directive pointing to it inside ./index.d.ts.

+ /// <reference path="./newfile.d.ts" />

./bundle.ts merges the types in this folder into a single file. To run it:

bun build
