Artifactory allows you to define any layout for your npm registries. In order to upload packages according to your custom layout, you need to package your npm files using the
npm pack command. This creates the .tgz file for your package which you can then upload to any path within your local npm repository.
Remote npm Registry
A Remote Repository defined in Artifactory serves as a caching proxy for a registry managed at a remote URL such as
. Artifacts (such as TGZ files) requested from a remote repository are cached on demand. You can remove downloaded artifacts from the remote repository cache, however, you can not manually deploy artifacts to a remote npm registry.
To define a remote repository to proxy a remote npm registry:
- In the Admin module, under Repositories | Remote, click New.
- In the New Remote Repository dialog:
a. Set the Package Type to npm and the Repository Key value.
b. Specify the URL to the remote registry in the URL field.
- Click Save & FInish.
Virtual npm Registry
A Virtual Repository defined in Artifactory aggregates packages from both local and remote repositories.
This allows you to access both locally hosted npm packages and remote proxied npm registries from a single URL defined for the virtual repository.
To define a virtual npm registry:
- Create a virtual repository, set the Package Type to npm.
- Select the underlying local and remote npm registries to include in the Basic settings tab.
- Click Save & Finish to create the repository.
The fields under External Dependency Rewrite are connected to automatically rewriting external dependencies for npm packages that require them.

Using the npm Command Line
When accessing an npm repository through Artifactory, the repository URL must be prefixed with api/npm in the path. This applies to all npm commands including
For example, if you are using Artifactory standalone or as a local service, you would access your npm repositories using the following URL:
Or, if you are using Artifactory SaaS, the URL would be:
To use the npm command line you need to make sure npm is installed. Npm is included as an integral part of recent versions of
Please refer to
Once you have created your npm repository, you can select it in the Tree Browser and click Set Me Up to get code snippets you can use to change your npm registry URL, deploy and resolve packages using the npm command line tool.
Setting the Default Registry
For your npm command line client to work with Artifactory, you first need to set the default npm registry with an Artifactory npm repository using the following command (the example below uses a repository called
npm config set registry http://<ARTIFACTORY_SERVER_DOMAIN>:8081/artifactory/api/npm/npm-repo/
For scoped packages, use the following command:
npm config set @<SCOPE>:registry http://<ARTIFACTORY_SERVER_DOMAIN>:8081/artifactory/api/npm/npm-repo/
We recommend referencing a Virtual Repository URL as a registry. This gives you the flexibility to reconfigure and aggregate other external sources and local repositories of npm packages you deployed.
Note that if you do this, you need to use the
Authenticating the npm Client
Once you have set the default registry, you need to authenticate the npm client to Artifactory in one of two ways:
- Running the
- Using basic authentication.
Using npm login
npm login was introduced in version 5.4.
Run the following command in your npm client. When prompted, provide your Artifactory login credentials:
Upon running this command, Artifactory creates a non-expirable access token which the client uses for authentication against Artifactory for subsequent and
npm publish actions.
If the token is removed from Artifactory, the client will have to log in again to receive a new token.
Using Basic Authentication
To support basic authentication, edit your
.npmrc file and enter the following:
- Your Artifactory username and password (formatted
Newtablink Text Base64 URL http://www.base64encode.org/
- Your email address (
npm publishwill not work if your email is not specified in
always-auth = true
Run the following command to retrieve these strings directly from Artifactory:
Where <CREDENTIAL> is your Artifactory password or API Key
Here is an example of the response:
If, in addition, you are also working with scoped packages, you also need to run the following command:
curl -uadmin:<CREDENTIAL> http://<ARTIFACTORY_SERVER_DOMAIN>:8081/artifactory/api/npm/npm-repo/auth/<SCOPE>
Where <CREDENTIAL> is your Artifactory password or API Key.
Paste the response to this command in the
~/.npmrc file on your machine (in Windows,
Resolving npm Packages
Once the npm command line tool is configured, every
npm install command will fetch packages from the npm repository specified above.
$ npm install request npm http GET http://localhost:8081/artifactory/api/npm/npm-repo/request npm http 200 http://localhost:8081/artifactory/api/npm/npm-repo/request npm http GET http://localhost:8081/artifactory/api/npm/npm-repo/request/-/request-2.33.0.tgz npm http 200 http://localhost:8081/artifactory/api/npm/npm-repo/request/-/request-2.33.0.tgz
Artifactory now supports
npm audit, allowing you to get vulnerabilities on your npm projects’ dependencies tree.
Audit reports contain information about security vulnerabilities of dependencies and can help fix a vulnerability by providing npm commands and recommendations for further troubleshooting.
This functionality will be enabled by default on npm virtual repositories that aggregate at least one remote repository that supports npm audit. For example, a remote repository that points to https://registry.npmjs.org or Artifactory Smart Remote repository.
JFrog Xray users with Artifactory Pro X / Enterprise / Enterprise+ license, will get an enhanced audit report that includes security vulnerabilities from Xray's database. When Xray is configured to work with Artifactory, an audit report can be generated from scratch even without connecting to any remote repository.
Users with Read Permission on the npm virtual repository can use the following npm commands:
|Returns a vulnerability report based on the dependency tree sent by the npm client that is generated by https://npmjs.com/ and optionally enhanced by Jfrog Xray.|
|Fetches the same report as |
In order to change the source of the npm audit reports, set the "npm.default.audit.provider" system property (default "https://registry.npmjs.org") to your desired audit provider url.
npm Publish (Deploying Packages)
Setting Your Credentials
The npm command line tool requires that sensitive operations, such as
publish are authenticated as described under Authenticating the npm Client above.
Deploying Your Packages
There are two ways to deploy packages to a local repository:
- Edit your
package.jsonfile and add a publishConfig section to a local repository:
- Provide a local repository to the
npm publish --registry
Specifying the Latest Version
By default, the "latest" version of a package in an npm registry in Artifactory is the one with the highest
artifactory.npm.tag.tagLatestByPublish = true
Working with Artifactory without Anonymous Access
By default, Artifactory allows anonymous access to npm repositories. This is defined in the Admin module under Security | General. For details, please refer to Allow Anonymous Access.
If you want to trace how users interact with your repositories you need to disable the Allow Anonymous Access setting. This means that users will be required to enter their username and password as described in Setting Your Credentials above.
Using OAuth Credentials
Artifactory uses GitHub Enterprise as its default OAuth provider. If you have an account, you may use your GitHub Enterprise login details to be authenticated when using the
npm login command.
Artifactory supports a variety of ways to search artifacts. For details, please refer to Searching Artifacts.
Artifactory also supports
npm search [search terms ...]. However, these packages may not be available immediately after being published for the following reasons:
- Local Repositories: When publishing a package to a local repository, Artifactory calculates the search index asynchronously.
- Virtual repositories: Since a virtual repository may contain local repositories, a newly published package may not be available immediately for the same reason.
In the case of remote repositories, a new package will only be found once Artifactory checks for it according to the Retrieval Cache Period setting.
Artifactory annotates each deployed or cached npm package with two properties:
You can use the Property Search to search for npm packages according to their name or version.
Cleaning Up the Local npm Cache
The npm client saves cached packages that were downloaded, as well as the JSON metadata responses (named
The JSON metadata cache files contain URLs which the npm client uses to communicate with the server, as well as other ETag elements sent by previous requests.
We recommend removing the npm caches (both packages and metadata responses) before using Artifactory for the first time. This is to ensure that your caches only contain elements that are due to requests from Artifactory and not directly from
The default cache directory on Windows is
%APPDATA%\npm-cache while on Linux it is
npm Scope Packages
Artifactory fully supports
By default, the npm client encodes slash characters ('/') to their ASCII representation ("%2f") before communicating with the npm registry. If you are running Tomcat as your HTTP container (the default for Artifactory), this generates an "HTTP 400" error since Tomcat does not allow encoded slashes by default. In order to work with npm scoped packages, you can override this default behavior by defining the following property in the
You can also add -Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true to the $ARTIFACTORY_HOME/etc/default for service installations or $ARTIFACTORY_HOME/bin/artifactory.default file. Note that since Artifactory version 4.4.3, the bundled Tomcat is configured by default to enable encoded slashes. If you are using a previous version you will need to adjust the Tomcat property above.
If Artifactory is running behind a reverse proxy, make sure to disable URL decoding on the proxy itself in order to work with npm scope packages.
For Apache, add the "AllowEncodedSlashes NoDecode" directive inside the <VirtualHost *:xxx> block.
Configuring the npm Client for a Scope Registry
Using Login Credentials
Scopes can be associated with a separate registry. This allows you to seamlessly use a mix of packages from the public npm registry and one or more private registries.
For example, you can associate the scope
@jfrog with the registry
http://localhost:8081/artifactory/api/npm/npm-local/ by manually altering your
~/.npmrc file and adding the following configuration:
@jfrog:registry=http://localhost:8081/artifactory/api/npm/npm-local/ //localhost:8081/artifactory/api/npm/npm-local/:_password=cGFzc3dvcmQ= //localhost:8081/artifactory/api/npm/npm-local/:username=admin //localhost:8081/artifactory/api/npm/npm-local/:email@example.com //localhost:8081/artifactory/api/npm/npm-local/:always-auth=true
From Artifactory 3.5.3, you can use the following command to get these strings directly from Artifactory:
$ curl -uadmin:password "http://localhost:8081/artifactory/api/npm/npm-local/auth/jfrog"
When using scope authentication, npm expects a valid email address. Please make sure you have included your email address in your Artifactory user profile.
The password is just a base64 encoding of your Artifactory password, the same way used by the old authentication configuration.
While npm scope packages have been available since version 2.0 of the npm command line tool, we highly recommend using npm scope packages with Artifactory only from version 2.1.9 of the npm command line tool.
Automatically Rewriting External Dependencies
Packages requested by the npm client frequently use external dependencies as defined in the packages'
package.json file. These dependencies may, in turn, need additional dependencies. Therefore, when downloading an npm package, you may not have full visibility into the full set of dependencies that your original package needs (whether directly or transitively). As a result, you are at risk of downloading malicious dependencies from unknown external resources.
To manage this risk, and maintain the best practice of consuming external packages through Artifactory, you may specify a "safe" whitelist from which dependencies may be downloaded, cached in Artifactory and configure to rewrite the dependencies so that the npm client accesses dependencies through a virtual repository as follows:
- Select the Enable Dependency Rewrite checkbox in the npm virtual repository advanced configuration.
- Specify a whitelist pattern of external resources from which dependencies may be downloaded.
- Specify the remote repository in which those dependencies should be cached.
It is preferable to configure a dedicated remote repository for that purpose so it is easier to maintain.
In the following example, the external dependencies are cached in the "npm" remote repository and only the package from
https://github.com/jfrogdev is allowed to be cached.
Artifactory supports all possible shorthand resolvers including the following:
git+ssh://user@hostname:project.git#commit-ish git+ssh://user@hostname/project.git#commit-ish git+https://firstname.lastname@example.org/<user>/<filename>.git
When downloading an npm package, Artifactory analyzes the list of dependencies required by the package.
If any of the dependencies are hosted on external resources (e.g. on
github.com), and those resources are specified in the whitelist,
Artifactory will download the dependency from the external resource.
Artifactory will cache the dependency in the remote repository configured to cache the external dependency.
Artifactory will then modify the dependency's entry in the package's package.json file indicating its new location in the Artifactory remote repository cache before returning it to the Npm client.
Consequently, every time the npm client needs to access the dependency, it will be provisioned from its new location in the Artifactory remote repository cache.
Viewing Individual npm Package Information
Artifactory lets you view selected metadata of an npm package directly from the UI.
In the Tree Browser, drill down to select the TGZ file you want to inspect. The metadata is displayed in the npm Info tab.
npm Build Information
You may store exhaustive build information in Artifactory by running your npm builds with JFrog CLI.
JFrog CLI collects build-info from your build agents and then publishes it to Artifactory. Once published, the build info can be viewed in the
Newtablink Text Build Browser URL https://www.jfrog.com/confluence/display/RTF/Build+Integration#BuildIntegration-InspectingBuilds
For more details on npm build integration using JFrog CLI, please refer to Building npm Packages in the JFrog CLI User Guide.
