# setup-bun
Download, install, and setup [Bun](https://bun.sh) in GitHub Actions.
## Usage
```yaml
- uses: oven-sh/setup-bun@v2
with:
bun-version: latest
```
## Using version file
```yaml
- uses: oven-sh/setup-bun@v2
with:
bun-version-file: ".bun-version"
```
### Using a custom NPM registry
```yaml
- uses: oven-sh/setup-bun@v2
with:
registry-url: "https://npm.pkg.github.com/"
scope: "@foo"
```
If you need to authenticate with a private registry, you can set the `BUN_AUTH_TOKEN` environment variable.
```yaml
- name: Install Dependencies
env:
BUN_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
run: bun install --frozen-lockfile
```
### Override download url
If you need to override the download URL, you can use the `bun-download-url` input.
```yaml
- 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](https://github.com/actions/setup-node) GitHub Action.
