Run/Debug Configuration: Attach to Node.js/Chrome

Host

In this field, specify the host where the application is running.

Port

In this field, specify the port passed to --inspect, --inspect-brk, or --debug when starting the Node.js process to connect to. Copy this port number from the information message in the Run tool window that controls the running application.

Attach to

In this area, choose the debugging protocol to use:

• Chrome or Node.js > 6.3 started with --inspect: choose this option to use the Chrome Debugging Protocol.

• Node.js < 8 started with --debug: choose this option to use the V8 Debugging Protocol (also known as Legacy Protocol).

Reconnect automatically

Select this checkbox to enable the PyCharm built-in debugger to re-attach to a running Node.js process after the code of the application is changed. This lets you debug Node.js applications that use the nodemon utility, which automatically reloads your Node.js process when the code is updated. See Debugging an application that uses nodemon for details.

Remote URLs of local files

In this area, specify the remote paths for the project folders. This is helpful if the root folder of the running application is different from the name of you PyCharm project root folder. In the example below, the PyCharm project root folder /Users/WsProjects/express is mapped to /usr/src/app on the server.

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.

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 PyCharm stores run configuration settings in .idea/workspace.xml.

Move the selected run/debug configuration up and down in the list.

The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.

Default templates of run/debug configurations are always sorted alphabetically.

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 icon to add one of the following available tasks:

• Run External tool: select to run an external application. In the dialog that opens, select one or multiple applications you want to run. If it is not defined in PyCharm yet, add its definition. For more information, see External tools and External Tools.

• Run Another Configuration: select to execute another run/debug configuration. In the dialog that opens, select the configuration to be run.

• Launch Web Browser: select this option to have a browser started. In the dialog that opens, select the type of the browser and provide the start URL. Also, specify if you want the browser be launched with JavaScript debugger.

• Run File Watchers: select this option to have PyCharm apply all the currently active File Watchers.

• Run Grunt task: select this option to run a Grunt task.

  In the Grunt task dialog that opens, specify the Gruntfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.

  Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the grunt-cli package.

• Run Gulp task: select this option to run a Gulp task.

  In the Gulp task dialog that opens, specify the Gulpfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Gulp tool.

  Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the gulp package.

• Run npm Script: select this option to execute an npm script.

  In the NPM Script dialog that opens, specify the npm run/debug configuration settings.

• Compile TypeScript: select to run the built-in TypeScript compiler and thus make sure that all the changes you made to your TypeScript code are reflected in the generated JavaScript files. In the TypeScript Compile Settings dialog that opens, select or clear the Check errors checkbox to configure the behaviour of the compiler in case any errors are detected:

  • If the Check errors checkbox is selected, the compiler will show all the errors and the run configuration will not start.

  • If the Check errors checkbox is cleared, the compiler will show all the detected errors but the run configuration still will be launched.

• Generate CoffeeScript Source Maps: select this option to generate the source maps for your CoffeeScript sources. In the dialog that opens, specify where your CoffeeScript source files are located.

• Run Remote External tool: adds a remote SSH external tool.

By default this checkbox is selected and the Run or the Debug tool window opens when you start the run/debug configuration.

Otherwise, if the checkbox is cleared, the tool window is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
