Bun supports loading configuration options from .npmrc files, allowing you to reuse existing registry/scope configurations.
{% callout %}
NOTE: We recommend migrating your .npmrc file to Bun's bunfig.toml format, as it provides more flexible options and can let you configure Bun-specific options.
{% /callout %}
Supported options
registry: 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:
registry=http://localhost:4873/
The equivalent bunfig.toml option is install.registry:
install.registry = "http://localhost:4873/"
@<scope>:registry: Set the registry for a specific scope
Allows you to set the registry for a specific scope:
@myorg:registry=http://localhost:4873/
The equivalent bunfig.toml option is to add a key in install.scopes:
[install.scopes]
myorg = "http://localhost:4873/"
//<registry_url>/:<key>=<value>: Configure options for a specific registry
Allows you to set options for a specific registry:
# 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:
_authTokenusername_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:
[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:
link-workspace-packages=true
The equivalent bunfig.toml option is install.linkWorkspacePackages:
[install]
linkWorkspacePackages = true
save-exact: Save exact versions
Always saves exact versions without the ^ prefix:
save-exact=true
The equivalent bunfig.toml option is install.exact:
[install]
exact = true
