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 the 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 contacting support for help. When this limit is enforced, our documentation will be updated with a way to work around it. For more information, see "AUTOTITLE" or "AUTOTITLE." {% 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 %}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 namespace that hosts the package (the personal account or organization {% ifversion packages-npm-v2 %}to which the package is scoped{% else %}that owns the repository where the package is hosted{% endif %}) when you authenticate to {% data variables.product.prodname_registry %}.

{% ifversion ghes %} If your instance has subdomain isolation enabled: {% endif %}

$ npm login --scope=@NAMESPACE --auth-type=legacy --registry=https://{% ifversion fpt or ghec %}npm.pkg.github.com{% else %}npm.HOSTNAME/{% 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 "AUTOTITLE."

You can connect a package to a repository as soon as the package is published by including a repository field in the package.json file. You can also use this method to connect multiple packages to the same repository. For more information, see "Publishing multiple packages to the same repository." {% else %} By default, your package is published in the {% data variables.product.prodname_dotcom %} repository that 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. You can publish multiple packages to the same {% data variables.product.prodname_dotcom %} repository by including a repository field in the package.json file. For more information, see "Publishing multiple packages to the same repository." {% endif %}

{% data reusables.package_registry.auto-inherit-permissions-note %}

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 @NAMESPACE/PACKAGE-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, if you're the user octocat and your package is named test, you would assign the scoped package name as follows: "name": "@octocat/test".

{% 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 %}

1. 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 it to the "My-org" {% data variables.product.prodname_dotcom %} organization, the name 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.

1. 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 {% ifversion packages-npm-v2 %}and link them {% endif %}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. For more information, see "Creating a package.json file" and "Creating Node.js modules" in the npm documentation.

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 personal account or organization on {% data variables.product.prodname_dotcom %} that owns the repository.

{% data variables.product.prodname_registry %} will match the repository based on the URL{% ifversion packages-npm-v2 %}{% else %}, instead of based on the package name{% endif %}.

"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 go through {% data variables.product.prodname_registry %}. 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.

{% data reusables.package_registry.authenticate-step %} {% data reusables.package_registry.create-npmrc-owner-step %} {% data reusables.package_registry.add-npmrc-to-repo-step %}

1. 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"
     }
   }

2. 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 %}HOSTNAME with the host name of {% data variables.location.product_location %} and {% endif %}NAMESPACE with the name of the personal account or organization {% ifversion packages-npm-v2 %}to which the package is scoped{% else %}that owns the repository containing the project{% endif %}.
