Working with the npm registry |
You can configure npm to publish packages to {% data variables.product.prodname_registry %} and to use packages stored on {% data variables.product.prodname_registry %} as dependencies in an npm project. |
{% data reusables.gated-features.packages %} |
|
|
npm registry |
{% data reusables.package_registry.packages-ghes-release-stage %} {% data reusables.package_registry.packages-ghae-release-stage %}
{% data reusables.package_registry.admins-can-configure-package-types %}
{% ifversion packages-npm-v2 %} {% else %}
If you publish over 1,000 npm package versions to {% data variables.product.prodname_registry %}, you may see performance issues and timeouts occur during usage.
In the future, to improve performance of the service, you won't be able to publish more than 1,000 versions of a package on {% data variables.product.prodname_dotcom %}. Any versions published before hitting this limit will still be readable.
If you reach this limit, consider deleting package versions or contact Support for help. When this limit is enforced, our documentation will be updated with a way to work around this limit. For more information, see "Deleting and restoring a package" or "Contacting Support." {% endif %}
{% data reusables.package_registry.authenticate-packages %}
{% ifversion packages-npm-v2 %}
This registry supports granular permissions. {% data reusables.package_registry.authenticate_with_pat_for_v2_registry %}
{% data reusables.package_registry.v2-actions-codespaces %} {% endif %}
{% data reusables.package_registry.required-scopes %}
You can authenticate to {% data variables.product.prodname_registry %} with npm by either editing your per-user ~/.npmrc file to include your {% data variables.product.pat_v1 %} or by logging in to npm on the command line using your username and {% data variables.product.pat_generic %}.
To authenticate by adding your {% data variables.product.pat_v1 %} to your ~/.npmrc file, edit the ~/.npmrc file for your project to include the following line, replacing {% ifversion ghes or ghae %}HOSTNAME with the host name of {% data variables.location.product_location %} and {% endif %}TOKEN with your {% data variables.product.pat_generic %}. Create a new ~/.npmrc file if one doesn't exist.
{% ifversion ghes %} If your instance has subdomain isolation enabled: {% endif %}
//{% ifversion fpt or ghec %}npm.pkg.github.com{% else %}npm.HOSTNAME/{% endif %}/:_authToken=TOKEN
{% ifversion ghes %} If your instance has subdomain isolation disabled:
//HOSTNAME/_registry/npm/:_authToken=TOKEN
{% endif %}
To authenticate by logging in to npm, use the npm login
command, replacing USERNAME with your {% data variables.product.prodname_dotcom %} username, TOKEN with your {% data variables.product.pat_v1 %}, and PUBLIC-EMAIL-ADDRESS with your email address.
If you are using npm CLI version 9 or greater and are logging in or out of a private registry using the command line, you should use the --auth-type=legacy
option to read in your authentication details from prompts instead of using the default login flow through a browser. For more information, see npm-login
.
If {% data variables.product.prodname_registry %} is not your default package registry for using npm and you want to use the npm audit
command, we recommend you use the --scope
flag with the owner of the package when you authenticate to {% data variables.product.prodname_registry %}.
{% ifversion ghes %} If your instance has subdomain isolation enabled: {% endif %}
$ npm login --scope=@OWNER --auth-type=legacy --registry=https://{% ifversion fpt or ghec %}npm.pkg.github.com{% else %}npm.HOSTNAME/{% endif %}
> Username: USERNAME
> Password: TOKEN
{% ifversion ghes %} If your instance has subdomain isolation disabled:
$ npm login --scope=@OWNER --auth-type=legacy --registry=https://HOSTNAME/_registry/npm/
> Username: USERNAME
> Password: TOKEN
{% endif %}
{% ifversion packages-npm-v2 %} {% note %}
Note:
- Package names and scopes must only use lowercase letters.
- The tarball for an npm version must be smaller than 256MB in size.
{% endnote %} {% else %} {% note %}
Note: Package names and scopes must only use lowercase letters.
{% endnote %}
{% endif %}
{% ifversion packages-npm-v2 %} The {% data variables.product.prodname_registry %} registry stores npm packages within your organization or personal account, and allows you to associate a package with a repository. You can choose whether to inherit permissions from a repository, or set granular permissions independently of a repository.
{% data reusables.package_registry.publishing-user-scoped-packages %} For more information on linking a published package with a repository, see "Connecting a repository to a package." {% endif %}
By default, {% data variables.product.prodname_registry %} publishes a package in the {% data variables.product.prodname_dotcom %} repository you specify in the name field of the package.json file. For example, you would publish a package named @my-org/test
to the my-org/test
{% data variables.product.prodname_dotcom %} repository. If you're running npm v8.5.3 or later, you can add a summary for the package listing page by including a README.md file in your package directory. For more information, see "Working with package.json" and "How to create Node.js Modules" in the npm documentation.
You can publish multiple packages to the same {% data variables.product.prodname_dotcom %} repository by including a URL
field in the package.json file. For more information, see "Publishing multiple packages to the same repository."
You can set up the scope mapping for your project using either a local .npmrc file in the project or using the publishConfig
option in the package.json. {% data variables.product.prodname_registry %} only supports scoped npm packages. Scoped packages have names with the format of @owner/name
. Scoped packages always begin with an @
symbol. You may need to update the name in your package.json to use the scoped name. For example, "name": "@codertocat/hello-world-npm"
.
{% data reusables.package_registry.viewing-packages %}
You can use an .npmrc file to configure the scope mapping for your project. In the .npmrc file, use the {% data variables.product.prodname_registry %} URL and account owner so {% data variables.product.prodname_registry %} knows where to route package requests. Using an .npmrc file prevents other developers from accidentally publishing the package to npmjs.org instead of {% data variables.product.prodname_registry %}.
{% data reusables.package_registry.authenticate-step %} {% data reusables.package_registry.create-npmrc-owner-step %} {% data reusables.package_registry.add-npmrc-to-repo-step %}
- Verify the name of your package in your project's package.json. The
name
field must contain the scope and the name of the package. For example, if your package is called "test", and you are publishing to the "My-org" {% data variables.product.prodname_dotcom %} organization, thename
field in your package.json should be@my-org/test
. {% data reusables.package_registry.verify_repository_field %} {% data reusables.package_registry.publish_package %}
You can use publishConfig
element in the package.json file to specify the registry where you want the package published. For more information, see "publishConfig" in the npm documentation.
- Edit the package.json file for your package and include a
publishConfig
entry. {% ifversion ghes %} If your instance has subdomain isolation enabled: {% endif %}
"publishConfig": {
"registry": "https://{% ifversion fpt or ghec %}npm.pkg.github.com{% else %}npm.HOSTNAME/{% endif %}"
},
{% ifversion ghes %} If your instance has subdomain isolation disabled:
"publishConfig": {
"registry": "https://HOSTNAME/_registry/npm/"
},
{% endif %} {% data reusables.package_registry.verify_repository_field %} {% data reusables.package_registry.publish_package %}
To publish multiple packages to the same repository, you can include the URL of the {% data variables.product.prodname_dotcom %} repository in the repository
field of the package.json file for each package.
To ensure the repository's URL is correct, replace REPOSITORY with the name of the repository containing the package you want to publish, and OWNER with the name of the user or organization account on {% data variables.product.prodname_dotcom %} that owns the repository.
{% data variables.product.prodname_registry %} will match the repository based on the URL, instead of based on the package name.
"repository":"https://{% ifversion fpt or ghec %}github.com{% else %}HOSTNAME{% endif %}/OWNER/REPOSITORY",
You can install packages from {% data variables.product.prodname_registry %} by adding the packages as dependencies in the package.json file for your project. For more information on using a package.json in your project, see "Working with package.json" in the npm documentation.
By default, you can add packages from one organization. For more information, see "Installing packages from other organizations."
You also need to add the .npmrc file to your project so that all requests to install packages will {% ifversion ghae %}be routed to{% else %}go through{% endif %} {% data variables.product.prodname_registry %}. {% ifversion fpt or ghes or ghec %}When you route all package requests through {% data variables.product.prodname_registry %}, you can use both scoped and unscoped packages from npmjs.org. For more information, see "npm-scope" in the npm documentation.{% endif %}
{% ifversion ghae %}
By default, you can only use npm packages hosted on your enterprise, and you will not be able to use unscoped packages. For more information on package scoping, see "npm-scope" in the npm documentation. If required, {% data variables.product.prodname_dotcom %} support can enable an upstream proxy to npmjs.org. Once an upstream proxy is enabled, if a requested package isn't found on your enterprise, {% data variables.product.prodname_registry %} makes a proxy request to npmjs.org.
{% endif %}
{% data reusables.package_registry.authenticate-step %} {% data reusables.package_registry.create-npmrc-owner-step %} {% data reusables.package_registry.add-npmrc-to-repo-step %}
- Configure package.json in your project to use the package you are installing. To add your package dependencies to the package.json file for {% data variables.product.prodname_registry %}, specify the full-scoped package name, such as
@my-org/server
. For packages from npmjs.com, specify the full name, such as@babel/core
or@lodash
. Replace<organization_name>/<package_name>
with your package dependency.
{
"name": "@my-org/server",
"version": "1.0.0",
"description": "Server app that uses the <organization_name>/<package_name> package",
"main": "index.js",
"author": "",
"license": "MIT",
"dependencies": {
"<organization_name>/<package_name>": "1.0.0"
}
}
- Install the package.
$ npm install
By default, you can only use {% data variables.product.prodname_registry %} packages from one organization. If you'd like to route package requests to multiple organizations and users, you can add additional lines to your .npmrc file, replacing {% ifversion ghes or ghae %}HOSTNAME with the host name of {% data variables.location.product_location %} and {% endif %}OWNER with the name of the user or organization account that owns the repository containing your project.
