Add a peer dependency with Bun

To add an npm package as a peer dependency, use the --peer flag.

bun add @types/bun --peer

This will add the package to peerDependencies in package.json.

json

{
  "peerDependencies": {
    "@types/bun": "^1.3.3"
  }
}

Running bun install will install peer dependencies by default, unless marked optional in peerDependenciesMeta.

json

{
  "peerDependencies": {
    "@types/bun": "^1.3.3"
  },
  "peerDependenciesMeta": {
    "@types/bun": { 
      "optional": true
    } 
  }
}
