bun add
Add packages to your project with Bun's fast package manager
To add a particular package:
bun add preact
To specify a version, version range, or tag:
bun add zod@3.20.0
bun add zod@^3.0.0
bun add zod@latest
--dev
Alias — --development, -d, -D
To add a package as a dev dependency ("devDependencies"):
bun add --dev @types/react
bun add -d @types/react
--optional
To add a package as an optional dependency ("optionalDependencies"):
bun add --optional lodash
--peer
To add a package as a peer dependency ("peerDependencies"):
bun add --peer @types/bun
--exact
Alias — -E
To add a package and pin to the resolved version, use --exact. This will resolve the version of the package and add it to your package.json with an exact version number instead of a version range.
bun add react --exact
bun add react -E
This will add the following to your package.json:
{
"dependencies": {
// without --exact
"react": "^18.2.0", // this matches >= 18.2.0 < 19.0.0
// with --exact
"react": "18.2.0" // this matches only 18.2.0 exactly
}
}

bun add --help
--global
To install a package globally, use the -g/--global flag. This will not modify the package.json of your current project. Typically this is used for installing command-line tools.
bun add --global cowsay # or `bun add -g cowsay`
cowsay "Bun!"

## Trusted dependencies
Unlike other npm clients, Bun does not execute arbitrary lifecycle scripts for installed dependencies, such as `postinstall`. These scripts represent a potential security risk, as they can execute arbitrary code on your machine.
To tell Bun to allow lifecycle scripts for a particular package, add the package to `trustedDependencies` in your package.json.
```json package.json icon="file-json" theme={"theme":{"light":"github-light","dark":"dracula"}}
{
"name": "my-app",
"version": "1.0.0",
"trustedDependencies": ["my-trusted-package"] // [!code ++]
}
Bun reads this field and will run lifecycle scripts for my-trusted-package.
Git dependencies
To add a dependency from a public or private git repository:
bun add git@github.com:moment/moment.git
Bun supports a variety of protocols, including github, git, git+ssh, git+https, and many more.
{
"dependencies": {
"dayjs": "git+https://github.com/iamkun/dayjs.git",
"lodash": "git+ssh://github.com/lodash/lodash.git#4.17.21",
"moment": "git@github.com:moment/moment.git",
"zod": "github:colinhacks/zod"
}
}
Tarball dependencies
A package name can correspond to a publicly hosted .tgz file. During installation, Bun will download and install the package from the specified tarball URL, rather than from the package registry.
bun add zod@https://registry.npmjs.org/zod/-/zod-3.21.4.tgz
This will add the following line to your package.json:
{
"dependencies": {
"zod": "https://registry.npmjs.org/zod/-/zod-3.21.4.tgz"
}
}
CLI Usage
bun add <package> <@version>
