title: .npmrc support
|

|
Bun supports loading configuration options from [`.npmrc`](https://docs.npmjs.com/cli/v10/configuring-npm/npmrc) files, allowing you to reuse existing registry/scope configurations.
|
|
|
|
<Note>
|
|
We recommend migrating your `.npmrc` file to Bun's [`bunfig.toml`](/runtime/bunfig) format, as it provides more
|
|
flexible options and can let you configure Bun-specific options.
|
|
</Note>

## Supported options
|
|
|
|
### Set the default registry
|
|
|
|
The default registry is used to resolve packages, its default value is `npm`'s official registry (`https://registry.npmjs.org/`).
|
|
|
|
To change it, you can set the `registry` option in `.npmrc`:
|
|
|
|
```ini .npmrc icon="npm"
|
|
registry=http://localhost:4873/
|
|
```
|
|
|
|
The equivalent `bunfig.toml` option is [`install.registry`](/runtime/bunfig#install-registry):
|
|
|
|
```toml bunfig.toml icon="settings"
|
|
install.registry = "http://localhost:4873/"
|
|
```
|
|
|
|
### Set the registry for a specific scope
|
|
|
|
`@<scope>:registry` allows you to set the registry for a specific scope:
|
|
|
|
```ini .npmrc icon="npm"
|
|
@myorg:registry=http://localhost:4873/
|
|
```
|
|
|
|
The equivalent `bunfig.toml` option is to add a key in [`install.scopes`](/runtime/bunfig#install-registry):
|
|
|
|
```toml bunfig.toml icon="settings"
|
|
[install.scopes]
|
|
myorg = "http://localhost:4873/"
|
|
```
|
|
|
|
### Configure options for a specific registry
|
|
|
|
`//<registry_url>/:<key>=<value>` allows you to set options for a specific registry:
|
|
|
|
```ini .npmrc icon="npm"
|
|
# set an auth token for the registry
|
|
# ${...} is a placeholder for environment variables
|
|
//http://localhost:4873/:_authToken=${NPM_TOKEN}
|
|
|
|
|
|
# or you could set a username and password
|
|
# note that the password is base64 encoded
|
|
//http://localhost:4873/:username=myusername
|
|
|
|
//http://localhost:4873/:_password=${NPM_PASSWORD}
|
|
|
|
# or use _auth, which is your username and password
|
|
# combined into a single string, which is then base 64 encoded
|
|
//http://localhost:4873/:_auth=${NPM_AUTH}
|
|
```
|
|
|
|
The following options are supported:
|
|
|
|
- `_authToken`
|
|
- `username`
|
|
- `_password` (base64 encoded password)
|
|
- `_auth` (base64 encoded username:password, e.g. `btoa(username + ":" + password)`)
|
|
|
|
The equivalent `bunfig.toml` option is to add a key in [`install.scopes`](/runtime/bunfig#install-registry):
|
|
|
|
```toml bunfig.toml icon="settings"
|
|
[install.scopes]
|
|
myorg = { url = "http://localhost:4873/", username = "myusername", password = "$NPM_PASSWORD" }
|
|
```
|
|
|
|
### `link-workspace-packages`: Control workspace package installation
|
|
|
|
Controls how workspace packages are installed when available locally:
|
|
|
|
```ini .npmrc icon="npm"
|
|
link-workspace-packages=true
|
|
```
|
|
|
|
The equivalent `bunfig.toml` option is [`install.linkWorkspacePackages`](/runtime/bunfig#install-linkworkspacepackages):
|
|
|
|
```toml bunfig.toml icon="settings"
|
|
[install]
|
|
linkWorkspacePackages = true
|
|
```
|
|
|
|
### `save-exact`: Save exact versions
|
|
|
|
Always saves exact versions without the `^` prefix:
|
|
|
|
```ini .npmrc icon="npm"
|
|
save-exact=true
|
|
```
|
|
|
|
The equivalent `bunfig.toml` option is [`install.exact`](/runtime/bunfig#install-exact):
|
|
|
|
```toml bunfig.toml icon="settings"
|
|
[install]
|
|
exact = true
|
|
```
