RubyMine 2023.3 Help

npm, pnpm, and Yarn

RubyMine integrates with the npm, pnpm, Yarn, Yarn 2, and Yarn 3, so you can install, locate, update, and remove packages of reusable code from inside the IDE, in the built-in Terminal.

RubyMine also lets you run and debug npm, Yarn, and pnpm scripts. RubyMine parses package.json files, recognizing definitions of scripts, shows scripts in a tree view, and lets you navigate between a script in the tree and its definition in the package.json file. For more information, refer to npm, Yarn, and pnpm official websites.

RubyMine detects projects with Yarn workspaces and indexes all the dependencies that are listed in the package.json files of the workspaces but are located in the root node_modules folder.

Before you start

  • Download and install Node.js. Note that npm is also installed, so if you are going to use it, you are through with the preliminary steps.

  • To use Yarn, install it as described on the Yarn official website.

  • To use pnpm, open the embedded Terminal (Alt+F12) and type:

    npm install --g pnpm

    Learn more from the pnpm official website.

Choose a project package manager

With RubyMine, you can choose whether to use npm, Yarn, Yarn 2, or pnpm in a project.

By default, RubyMine suggests npm. However, if you open a project with a yarn.lock file and Yarn is installed on your computer, RubyMine automatically changes the package manager for this project to Yarn.

Accordingly, if you open a project with a pnpm-lock file and pnpm is installed on your computer, RubyMine automatically changes the package manager for this project to pnpm.

You can also set Yarn 1 or pnpm as default RubyMine package manager.

  1. In the Settings dialog (Control+Alt+S), go to Languages & Frameworks | Node.js. The Node.js page opens.

  2. In the Package manager field, specify the package manager for your project.

    Select project package manager: choose the system default installation
    • Select npm, yarn, or pnpm to use the system default installation.

    • To use a custom installation of a package manager, click Select, and select the installation folder of the relevant package manager.

      Select project package manager: choose a custom installation

    RubyMine automatically uses the chosen package manager when you select the Project alias from the Package manager list in the Run/Debug Configuration: NPM dialog. RubyMine also uses the path to the chosen package manager every time you invoke the Run 'npm install'/Run 'yarn install'/Run 'pnpm install' command or run an npm/Yarn/pnpm script. For more information, refer to Running and debugging scripts.

Set up Yarn 2 in your project

  1. Make sure you have Yarn 1 installed globally and enable Yarn 2 in your project as described on the Yarn official website. Use the embedded Terminal Alt+F12 to type the commands.

  2. In the Settings dialog (Control+Alt+S), go to Languages & Frameworks | Node.js and select the path to the Yarn 2 package in your project from the Package manager list.

Set Yarn 1 or pnpm as the default RubyMine package manager

  1. Open the Settings for New Projects dialog (File | New Projects Setup | Settings for New Projects) and go to Languages & Frameworks | Node.js.

  2. On the Node.js and NPM page that opens, select yarn or pnpm from the Package manager list.

After that, RubyMine will suggest the selected package manager (Yarn or pnpm) as default every time you create a new project.

Edit package.json

Install and update packages

As you may know, npm can install packages both globally or as project dependencies or development dependencies, learn more from the npm official website.

pnpm also installs packages globally or as project dependencies or development dependencies, learn more from the pnpm official website.

With Yarn, you can install packages globally or as project dependencies. For more information, refer to Yarn official website.

In RubyMine, packages can be installed in the editor, from a package.json file, in the built-in Terminal Alt+F12, or on the Node.js page.

From package.json

Install your project dependencies

  • Click the Run 'npm install', Run 'yarn install', or Run 'pnpm install' link in the popup:

    Install dependencies popup

    RubyMine shows this popup when the dependencies are not installed yet or when they have changed. If you close the popup or turn it off by choosing Don't ask again, you can still install the dependencies using the Run '<package_manager> install' action or in the built-in terminal.

    If you have accidentally dismissed this notification and now want to get it back, press Control+Shift+A, start typing Enable notifications, and select Enable Notifications about Installing Dependencies from package.json from the list.

  • Alternatively, open the relevant package.json file in the editor or select it in the Project tool window and choose Run 'npm install' from the context menu.

Update your project dependencies

  • Click Run '<package manager> install' in the popup.

    Update dependencies: popup

    RubyMine shows this popup every time you open a project, update it from the version control, or edit a package.json.

  • RubyMine also runs an inspection that checks whether the packages from dependencies or devDependencies are installed and their versions match the specified range. If the inspection detects any mismatch, it suggests a quick-fix. To apply it, click the Run '<package manager> install' link.

    Installed version of a package is not up to date
  • RubyMine also detects packages for which later versions are available and provides a quick-fix when you hover over the package version.

    Update package to latest version: tooltip

    Alternatively, press Alt+Enter and select Update <package> to the latest version from the list:

    Update package to latest version: quick-fix

In the built-in Terminal

In the embedded Terminal (Alt+F12) , type one of the following commands:

  • For global installation:

    • npm install --global <package_name>

    • yarn global add <package_name>

    • pnpm --global add <package_name>

  • To install a package as a project dependency or a development dependency:

    • npm install --save <package_name> or npm install --save-dev <package_name>

    • yarn add <package_name> --dev

    • pnpm add --save-dev <package_name>

Install all dependencies listed in a package.json file

In the embedded Terminal (Alt+F12) , type one of the following commands:

  • npm install

  • yarn install

  • pnpm install

As a result you get all the dependencies listed in the package.json from the current folder. Learn more from Editing package.json.

Detect vulnerable packages

RubyMine detects vulnerabilities in the packages used in your projects by checking across the Checkmarx SCA Database and the National Vulnerability Database. Vulnerability check is handled by Security code inspections.

As you write your code, the IDE highlights packages that are considered vulnerable, provides descriptions for them, and suggests fixes where available.

Detect vulnerable packages and fix them in the editor

In the Problems tool window, you can view a list of detected vulnerable packages.

  • To solve package vulnerability problems in the editor, hover over the highlighted package in a package.json file. The popup tool window shows a description of the detected vulnerability.

    To apply a quick-fix, click More actions Alt+Enter and select the relevant suggestion.

  • To view vulnerable packages in the Problems tool window, click the Problems icon in the inspection widget.

    • The File tab of the Problems tool window lists all the vulnerable packages from the package.json that is open in the active editor tab. Each item is supplied with a description.

      To solve a problem, select the vulnerable package in the list, click the Yellow bulb icon on the toolbar or press Alt+Enter, and then select the relevant suggestion.

    • The Vulnerable Dependencies tab lists all the vulnerable packages detected in your project.

      Problems tool window: Vulnerable Dependencies tab

      To fix a problem, select the vulnerable package in the list, click the Copy safe version to clipboard link on the right-hand pane, and then paste the copied version to your package.json.

    Learn more from Get results and fix problems.

  • By default, package vulnerability check is enabled. To turn it off, open the Settings dialog (Control+Alt+S), go to Editor | Inspection, and clear the checkboxes next to the relevant inspections under the Security node.

Run and debug scripts

You can launch npm, Yarn, or pnpm scripts from a package.json file in the editor, from a tree of scripts in the dedicated npm tool window, according to a dedicated run configuration, or automatically, as a start-up or a before-launch task.

The results of script execution are displayed in the Run tool window. The tool window shows the npm or Yarn script output, reports the errors occurred, lists the packages or plugins that have not been found, etc. The name of the last executed script is displayed on the title bar of the tool window.

Running a script: Run tool window

If you launch a script debugging session, RubyMine opens the Debug tool window.

Debugging a script: Debug tool window

During a script debugging session, you can step through the script, stop and resume the script execution, examine it when suspended, run JavaScript code snippets in the Debugger Console, and so on.

Run and debug scripts from package.json

RubyMine lets you quickly launch single scripts from package.json files. To run or debug several scripts, use a run configuration or the npm tool window.

  • Open the package.json file in the editor, click the Run button in the gutter next to the script, and choose Run <script_name> or Debug <script_name> from the context menu.

    Run/debug a script from package.json
  • You can also run a script by pressing Control+Shift+F10.

The script output is shown in the Run tool window.

If you launch a script in the debug mode, RubyMine opens the Debug tool window, where you can step through the script, stop and resume the script execution, examine it when suspended, run JavaScript code snippets in the Debugger Console, and so on.

Run and debug scripts from the npm tool window

The npm tool window opens when you select a package.json file in the Project tool window or open it in the editor and select Show npm Scripts from the context menu.

As soon as you invoke npm, pnpm, or Yarn, the tool starts building a tree of scripts defined within the scripts property of the package.json file on which it was invoked.

If you have several package.json files in your project, you can build a separate script tree for each of them and run scripts without dropping the previously built trees. Each tree is shown under a separate node.

Open the npm tool window if it is not opened yet

  • Select the required file in the Project tool window or open it in the editor and choose Show npm Scripts from the context menu.

    Open the nmp tool window

    The npm tool window opens showing the scripts tree built according to the selected or opened package.json file.

Build a tree of scripts in an already opened npm tool window

  1. In the npm tool window, click the Add button on the toolbar and choose the required package.json file from the list. By default, RubyMine shows the package.json file in the root of your project.

  2. If you have another package.json file, click Choose package.json and select the package.json file you need in the dialog that opens. RubyMine adds a new node with the path to the chosen package.json file on its title and builds a scripts tree under the new node.

  • Use the multiselect mode: hold Shift (for adjacent items) or Control (for non-adjacent items) keys and select the required scripts, then choose Run or Debug from the context menu of the selection.

    Run multiple scripts

Run and debug scripts by a run configuration

When you run or debug scripts from the editor or from the npm tool window, RubyMine automatically creates temporary run configurations. Besides using them, you can create and launch your own npm run configurations.

Create an NPM run/debug configuration

  1. Go to Run | Edit Configurations. Alternatively, select Edit Configurations from the list on the toolbar.

    Open the Edit Configurations dialog
  2. In the Edit Configurations dialog that opens, click the Add button (the Add button) on the toolbar and select npm from the list. The Run/Debug Configuration: npm dialog opens.

  3. Specify the CLI command to execute, the scripts to run (use blank spaces as separators), and the location of the package.json file where these scripts are defined. Optionally, type the command-line arguments for executing the scripts.

  4. Specify the Node.js interpreter to use.

    If you choose the Project alias, RubyMine will automatically use the project default interpreter from the Node interpreter field on the Node.js page . In most cases, RubyMine detects the project default interpreter and fills in the field itself.

    You can also choose another configured local or remote interpreter or click the Browse button and configure a new one.

    Optionally specify the Node.js-specific option parameters and the environment variables to be passed to Node.js.

  5. Specify the package manager to use. If you choose the Project alias, RubyMine will use the default project package manager from the Node.js page. You can also choose the relevant package alias (npm or yarn) or specify an explicit path to a custom installation of a package manager.

  6. If you are using a remote Node.js interpreter in a Docker container, check the port and volume bindings values in the Docker container settings field.

    Check Docker container settings
