Run/Debug Configuration: NPM

Create: Run | Edit Configurations | | NPM

In this dialog, create configurations for running npm and Yarn scripts locally. "Locally" in the current context means that PhpStorm itself starts Node.js installed on your computer, whereupon initiates script execution.

Learn more from npm, pnpm, and Yarn.

If a script launches an application in the development mode, you can modify the configuration, so it also starts a debugging session. To do that, go to the Browser / Live Edit tab and specify there the URL address at which the application will run. Learn more from Run and debug an Angular application with a single npm run/debug configuration, Run and debug a Vue.js application with a single npm run/debug configuration, and Run and debug a Vite application with a single npm run/debug configuration.

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.

Configuration tab

Item	Description
package.json	In this field, specify the package.json file to run the scripts from. Choose the file from the drop-down list which shows all the package.json files detected in the current project or click and choose the required package.json in the dialog that opens.
Command	From this list, choose the npm CLI command to execute, by default `run-script` is selected. Learn more at npm documentation, under the section CLI Commands.
Scripts	From this drop-down list, choose the script to which the chosen command will be applied. The list contains all the scripts defined within the `scripts` property in the package.json file.
Arguments	In this field, specify the command-line arguments to execute a script with. Learn more from the npm official website.
Node interpreter	In this field, specify the Node.js interpreter to use. If you choose the Project alias, PhpStorm will automatically use the project default interpreter from the Node interpreter field on the Node.js page . In most cases, PhpStorm detects the project default interpreter and fills in the field itself. You can also choose another configured local or remote interpreter or click and configure a new one.
Node Options	In this field, type the Node.js-specific command-line options to be passed to the Node.js executable file. The acceptable options are: Use `--require coffeescript/register` to have CoffeeScript files compiled into JavaScript on the fly during run. This mode requires that the register.js file, which is a part of the `coffeescript` package, is located inside your project. Therefore, make sure you have the `coffeescript` package installed locally as described in Install the CoffeeScript compiler. Use `--inspect` or `--inspect-brk` parameter for Chrome Debugging Protocol support.
Package manager	In this field. specify the package manager to use. If you choose the `Project` alias, PhpStorm 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.
Environment Variables	In this field, specify the environment variables for the Node.js executable file, if applicable. Click Browse to the right of the field and configure a list of variables in the Environment Variables dialog, that opens: To define a new variable, click and specify the variable name and value. To discard a variable definition, select it in the list and click . Click OK, when ready The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators, for example: `NODE_PATH`: A `:`-separated list of directories prefixed to the module search path. `NODE_MODULE_CONTEXTS`: Set to 1 to load modules in their own global contexts. `NODE_DISABLE_COLORS`: Set to 1 to disable colors in the REPL.
Docker container settings	This read-only field shows port and volume bindings. Click to open the command preview. This field only appears when a Docker-based remote interpreter is selected.
Docker Compose	In this area, specify the commands and options to be passed to Docker Compose. Accept the default settings or click and specify custom ones, for example, custom Docker Compose flags, like `--rm` or `--service-ports`. Learn more from the Docker official website. Check the Command Preview. This field only appears when a remote interpreter via Docker Compose is selected.

Common settings

When you edit a run configuration (but not a run configuration template), you can specify the following options:

Item	Description
Name	Specify a name for the run configuration to quickly identify it among others when editing or running.
Allow multiple instances	Allow running multiple instances of this run configuration in parallel. By default, it is disabled, and when you start this configuration while another instance is still running, PhpStorm suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.
Store as project file	Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project. By default, it is disabled, and PhpStorm stores run configuration settings in .idea/workspace.xml.

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow multiple instances

Allow running multiple instances of this run configuration in parallel.

By default, it is disabled, and when you start this configuration while another instance is still running, PhpStorm suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.

By default, it is disabled, and PhpStorm stores run configuration settings in .idea/workspace.xml.

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Item	Shortcut	Description
	`Alt+Insert`	Create a run/debug configuration.
	`Alt+Delete`	Delete the selected run/debug configuration. Note that you cannot delete default configurations.
	`Ctrl+D`	Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
		The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
		Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders. To create a folder, select the configurations within a category, click , and specify the folder name. If only a category is in focus, an empty folder is created. Then, to move a configuration into a folder, between the folders or out of a folder, use drag or and buttons. To remove grouping, select a folder and click .
		Click this button to sort configurations in the alphabetical order.
