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

Install the bun-types npm package:

# yarn/npm/pnpm work too, "bun-types" is an ordinary npm package
bun add -d bun-types

Add this to your tsconfig.json or jsconfig.json:

  {
    "compilerOptions": {
+     "types": ["bun-types"]
      // other options...
    }

    // other options...
  }

bun-types 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
