The `bun` CLI contains a Node.js-compatible package manager designed to be a dramatically faster replacement for `npm`, `yarn`, and `pnpm`. It's a standalone tool that will work in pre-existing Node.js projects; if your project has a `package.json`, `bun install` can help you speed up your workflow.

**⚡️ 25x faster** — Switch from `npm install` to `bun install` in any Node.js project to make your installations up to 25x faster.

{% details summary="For Linux users" %}
|
|
The minimum Linux Kernel version is 5.1. If you're on Linux kernel 5.1 - 5.5, `bun install` should still work, but HTTP requests will be slow due to a lack of support for io_uring's `connect()` operation.
|
|
|
|
If you're using Ubuntu 20.04, here's how to install a [newer kernel](https://wiki.ubuntu.com/Kernel/LTSEnablementStack):
|
|
|
|
```bash
|
|
# If this returns a version >= 5.6, you don't need to do anything
|
|
uname -r
|
|
|
|
# Install the official Ubuntu hardware enablement kernel
|
|
sudo apt install --install-recommends linux-generic-hwe-20.04
|
|
```

## Manage dependencies
|
|
|
|
### `bun install`
|
|
|
|
To install all dependencies of a project:
|
|
|
|
```bash
|
|
$ bun install
|
|
```
|
|
|
|
On Linux, `bun install` tends to install packages 20-100x faster than `npm install`. On macOS, it's more like 4-80x.
|
|
|
|
|
|
|
|
Running `bun install` will:
|
|
|
|
- **Install** all `dependencies`, `devDependencies`, and `optionalDependencies`. Bun does not install `peerDependencies` by default.
|
|
- **Run** your project's `{pre|post}install` scripts at the appropriate time. For security reasons Bun _does not execute_ lifecycle scripts of installed dependencies.
|
|
- **Write** a `bun.lockb` lockfile to the project root.
|
|
|
|
To install in production mode (i.e. without `devDependencies`):
|
|
|
|
```bash
|
|
$ bun install --production
|
|
```
|
|
|
|
To install dependencies without allowing changes to lockfile (useful on CI):
|
|
|
|
```bash
|
|
$ bun install --frozen-lockfile
|
|
```
|
|
|
|
To perform a dry run (i.e. don't actually install anything):
|
|
|
|
```bash
|
|
$ bun install --dry-run
|
|
```
|
|
|
|
To modify logging verbosity:
|
|
|
|
```bash
|
|
$ bun install --verbose # debug logging
|
|
$ bun install --silent # no logging
|
|
```
|
|
|
|
{% details summary="Configuring behavior" %}
|
|
The default behavior of `bun install` can be configured in `bun.toml`:
|
|
|
|
```toml
|
|
[install]
|
|
|
|
# whether to install optionalDependencies
|
|
optional = true
|
|
|
|
# whether to install devDependencies
|
|
dev = true
|
|
|
|
# whether to install peerDependencies
|
|
peer = false
|
|
|
|
# equivalent to `--production` flag
|
|
production = false
|
|
|
|
# equivalent to `--frozen-lockfile` flag
|
|
frozenLockfile = false
|
|
|
|
# equivalent to `--dry-run` flag
|
|
dryRun = false
|
|
```
|
|
|
|
{% /details %}
|
|
|
|
### `bun add`
|
|
|
|
To add a particular package:
|
|
|
|
```bash
|
|
$ bun add preact
|
|
```
|
|
|
|
To specify a version, version range, or tag:
|
|
|
|
```bash
|
|
$ bun add zod@3.20.0
|
|
$ bun add zod@^3.0.0
|
|
$ bun add zod@latest
|
|
```
|
|
|
|
To add a package as a dev dependency (`"devDependencies"`):
|
|
|
|
```bash
|
|
$ bun add --development @types/react
|
|
$ bun add -d @types/react
|
|
```
|
|
|
|
To add a package as an optional dependency (`"optionalDependencies"`):
|
|
|
|
```bash
|
|
$ bun add --optional lodash
|
|
```
|
|
|
|
To install a package globally:
|
|
|
|
```bash
|
|
$ bun add --global cowsay # or `bun add -g cowsay`
|
|
$ cowsay "Bun!"
|
|
______
|
|
< Bun! >

{% details summary="Configuring global installation behavior" %}
|
|
|
|
```toml
|
|
[install]
|
|
# where `bun install --global` installs packages
|
|
globalDir = "~/.bun/install/global"
|
|
|
|
# where globally-installed package bins are linked
|
|
globalBinDir = "~/.bun/bin"
|
|
```
|
|
|
|
{% /details %}
|
|
To view a complete list of options for a given command:
|
|
|
|
```bash
|
|
$ bun add --help
|
|
```
|
|
|
|
### `bun remove`
|
|
|
|
To remove a dependency:
|
|
|
|
```bash
|
|
$ bun remove preact
|
|
```
|
|
|
|
## Local packages (`bun link`)
|
|
|
|
Use `bun link` in a local directory to register the current package as a "linkable" package.
|
|
|
|
```bash
|
|
$ cd /path/to/cool-pkg
|
|
$ cat package.json
|
|
{
|
|
"name": "cool-pkg",
|
|
"version": "1.0.0"
|
|
}
|
|
$ bun link
|
|
bun link v0.5.7 (7416672e)
|
|
Success! Registered "cool-pkg"
|
|
|
|
To use cool-pkg in a project, run:
|
|
bun link cool-pkg
|
|
|
|
Or add it in dependencies in your package.json file:
|
|
"cool-pkg": "link:cool-pkg"
|
|
```
|
|
|
|
This package can now be "linked" into other projects using `bun link cool-pkg`. This will create a symlink in the `node_modules` directory of the target project, pointing to the local directory.
|
|
|
|
```bash
|
|
$ cd /path/to/my-app
|
|
$ bun link cool-pkg
|
|
```
|
|
|
|
In addition, the `--save` flag can be used to add `cool-pkg` to the `dependencies` field of your app's package.json with a special version specifier that tells Bun to load from the registered local directory instead of installing from `npm`:
|
|
|
|
```json-diff
|
|
{
|
|
"name": "my-app",
|
|
"version": "1.0.0",
|
|
"dependencies": {
|
|
+ "cool-pkg": "link:cool-pkg"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Git dependencies
|
|
|
|
To add a dependency from a git repository:
|
|
|
|
```bash
|
|
$ bun install git@github.com:moment/moment.git
|
|
```
|
|
|
|
Bun supports a variety of protocols, including [`github`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#github-urls), [`git`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#git-urls-as-dependencies), `git+ssh`, `git+https`, and many more.
|
|
|
|
```json
|
|
{
|
|
"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 publically hosted `.tgz` file. During `bun install`, Bun will download and install the package from the specified tarball URL, rather than from the package registry.
|
|
|
|
```json#package.json
|
|
{
|
|
"dependencies": {
|
|
"zod": "https://registry.npmjs.org/zod/-/zod-3.21.4.tgz"
|
|
}
|
|
}
|
|
```
|
|
|
|
## CI/CD
