Add a peer dependency

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.

{
  "peerDependencies": {
+   "@types/bun": "^$BUN_LATEST_VERSION"
  }
}

---

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

{
  "peerDependencies": {
    "@types/bun": "^$BUN_LATEST_VERSION"
  },
  "peerDependenciesMeta": {
+   "@types/bun": {
+     "optional": true
+   }
  }

}
