setup-bun

Download, install, and setup Bun in GitHub Actions.

Usage

- uses: oven-sh/setup-bun@v2
  with:
    bun-version: latest

Using version file

- uses: oven-sh/setup-bun@v2
  with:
    bun-version-file: ".bun-version"

Using custom registries

You can configure multiple package registries using the registries input. This supports both default and scoped registries with various authentication methods.

Registry configuration

- uses: oven-sh/setup-bun@v2
  with:
    registries: |
      https://registry.npmjs.org/
      @myorg:https://npm.pkg.github.com/|$GITHUB_TOKEN
      @internal:https://username:$INTERNAL_PASSWORD@registry.internal.com/

- name: Install dependencies
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    INTERNAL_PASSWORD: ${{ secrets.INTERNAL_PASSWORD }}
  run: bun install

Registry format options

Type Format
Default registry https://registry.example.com/
Default registry with token https://registry.example.com/|$TOKEN
Scoped registry @scope:https://registry.example.com/
Scoped registry with token @scope:https://registry.example.com/|$TOKEN
Scoped registry with URL credentials @scope:https://username:$PASSWORD@registry.example.com/

Important

When using authentication, make sure to set the corresponding environment variables in your workflow steps that need access to the registries.

For more information about configuring registries in Bun, see the official documentation.

Override download url

If you need to override the download URL, you can use the bun-download-url input.

- uses: oven-sh/setup-bun@v2
  with:
    bun-download-url: "https://github.com/oven-sh/bun/releases/latest/download/bun-linux-x64.zip"

Node.js not needed

In most cases, you shouldn't need to use the setup-node GitHub Action.
