Run/Debug Configuration: NW.js
In this dialog, create configurations for running NW.js applications and debugging their main processes.
To debug background and additional main processes, use the Attach to Node.js/Chrome run/debug configuration as described in Debugging a running Node.js application.
Before you start
Install NW.js. If you are going to debug your application, make sure you are using the SDK build of NW.js.
Install the Node.js plugin on the Settings | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains repository.
NW.js-specific configuration settings
In this field, specify the application to launch. You can select an entire directory that contains a package.json file or the same directory packed into an archive with the .nw extension.
In this field, specify the arguments to be passed to NW.js. If necessary, click and type the arguments in the textual editor that opens.
In this field, specify the working directory of the application. By default, the Working directory field shows the project root folder. To change this predefined setting, specify the path to the desired folder.
In this field, specify the environment variables for the executable file, if applicable.
Specify the path to the NW.js executable file.
When you edit a run configuration (but not a run configuration template), you can specify the following options:
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, PyCharm 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 PyCharm 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.
Create a run/debug configuration.
Delete the selected run/debug configuration. Note that you cannot delete default configurations.
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.
In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Click this icon to add one of the following available tasks:
Click this icon to remove the selected task from the list.
Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
Click these icons to move the selected task one line up or down in the list. The tasks are performed in the order that they appear in the list.
Show this page
Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.
Activate tool window
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.
