Run/Debug Configuration: NPM

Last modified: 26 June 2023

Required plugins:

JavaScript and TypeScript - The plugin is bundled with GoLand and enabled by default.

Node.js - Install the plugin on the Settings | Plugins page, tab Marketplace.

Create: Run | Edit Configurations | Add New Configuration | NPM

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

Before you start

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 the Browse button and choose the required package.json in the dialog box 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, GoLand will automatically use the project default interpreter from the Node interpreter field . In most cases, GoLand detects the project default interpreter and fills in the field itself.

You can also choose another configured local interpreter or click the Browse button 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.

  • Use --inspect or --inspect-brk parameter when you are using Node.js v7 for Chrome Debugging Protocol support. Otherwise, by default the debug process will use V8 Debugging Protocol.

Package manager

In this field. specify the package manager to use. If you choose the Project alias, GoLand 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 the Browse button 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 the Add button and specify the variable name and value.

  • To discard a variable definition, select it in the list and click the Remove button.

  • 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 the Expand button to open the command preview.

Check Docker container settings

Docker Compose

In this area, specify the commands and options to be passed to Docker Compose. Accept the default settings or click the Expand button 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.

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, GoLand 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 GoLand stores run configuration settings in .idea/workspace.xml.

Toolbar

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.

Move into new folder / Create new folder

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 Folder, 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 Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.
