The default registry is `registry.npmjs.org`. This can be globally configured in `bunfig.toml`:

```toml
[install]
# set default registry as a string
registry = "https://registry.npmjs.org"
# set a token
registry = { url = "https://registry.npmjs.org", token = "123456" }
# set a username/password
registry = "https://username:password@registry.npmjs.org"
```

To configure a private registry scoped to a particular organization:

```toml
[install.scopes]
# registry as string
"@myorg1" = "https://username:password@registry.myorg.com/"

# registry with username/password
# you can reference environment variables
"@myorg2" = { username = "myusername", password = "$NPM_PASS", url = "https://registry.myorg.com/" }

# registry with token
"@myorg3" = { token = "$npm_token", url = "https://registry.myorg.com/" }
```

### `.npmrc`

Bun does not currently read `.npmrc` files. For private registries, migrate your registry configuration to `bunfig.toml` as documented above.
