Add a peer dependency

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

terminal

bun add @types/bun --peer

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

package.json

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

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

package.json

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

See Docs > Package manager for complete documentation of Bun’s package manager.
