Run/Debug Configuration: 运行/调试配置：NPM

Run | Edit Configurations | Add New Configuration | NPM

This page describes the configuration-specific items as well as options that are common for all run/debug configurations. 此页面描述了特定于配置的项目以及所有运行/调试配置的常见选项。To learn how to use this configuration, see npm, pnpm, and Yarn.要了解如何使用此配置，请参阅npm、pnpm和Yarn。

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

Learn more from npm, pnpm, and Yarn.从npm、pnpm和Yarn中了解更多信息。

Before you start开始之前

  1. Download and install Node.js. 下载并安装Node.js。Note that npm is also installed so if you are going to use it you are through with the preliminary steps.请注意，还安装了npm，所以如果您打算使用它，您就完成了初步步骤。

  2. To use Yarn, install it as described on the Yarn official website.要使用Yarn，请按照Yarn官方网站上的说明进行安装。

Description描述
package.jsonIn 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.
CommandFrom 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.
ScriptsFrom 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.
ArgumentsIn 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. This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux.

Node Options节点选项

In this text box, type the Node.js-specific command-line options to be passed to the Node.js executable file. 在此文本框中，键入要传递到Node.js可执行文件的Node.js特定命令行选项。The acceptable options are:可接受的选择是：

  • 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. 此模式要求register.js文件位于项目内部，它是coffeescript包的一部分。Therefore make sure you have the coffeescript package installed locally as described in Install the CoffeeScript compiler.

  • 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 managerIn this field. specify the package manager to use. If you choose the Project alias, WebStorm 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准备好后，单击“确定”

The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators, for example:变量的定义以分号作为分隔符显示在环境变量只读字段中，例如：

  • 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.

Common

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/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10.

Allow parallel run

Select to 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, WebStorm suggests to stop the running instance and start another one. This is helpful when a run/debug 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 WebStorm 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.

the Add buttonAlt+InsertCreate a run/debug configuration.
the Remove buttonAlt+DeleteDelete the selected run/debug configuration. Note that you cannot delete default configurations.
CopyCtrl+DCreate a copy of the selected run/debug configuration. Note that you create copies of default configurations.
Save configurationThe 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

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.

Sort configurations Click this button to sort configurations in the alphabetical order.单击此按钮可按字母顺序对配置进行排序。

Before launch发射前

In this area, you can specify tasks to be performed before starting the selected run/debug configuration. 在此区域中，可以指定在启动所选运行/调试配置之前要执行的任务。The tasks are performed in the order they appear in the list.任务将按照它们在列表中的显示顺序执行。
