bun update – Package manager

To update all dependencies to the latest version:

bun update

To update a specific dependency to the latest version:

bun update [package]

`--latest`

By default, bun update will update to the latest version of a dependency that satisfies the version range specified in your package.json.

To update to the latest version, regardless of if it's compatible with the current version range, use the --latest flag:

bun update --latest

For example, with the following package.json:

{
  "dependencies": {
    "react": "^17.0.2"
  }
}

bun update would update to a version that matches 17.x.
bun update --latest would update to a version that matches 18.x or later.
