Alistair Smith 1d50af7fe8 @types/bun: Update to @types/node@25, fallback to PropertyKey in test expect matchers when keyof unknown is used (#25460)
more accurately, developers cannot pass a value when expect values
resolve to never. this is easy to fall into when using the
`toContainKey*` matchers. falling back to PropertyKey when this happens
is a sensible/reasonable default

TypeScript types for Bun

Logo

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.

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