Information and settings

Item	Description
Name	In this field, specify the name of the current run/debug configuration.
Server command	Use the following command on the server side to enable remote debug: `rdebug-ide --host 0.0.0.0 --port <port number> --dispatcher-port <port number> -- $COMMAND$` This read-only field shows the command that should be entered on the server side to launch the debug server. Port and dispatcher-port numbers here are taken from the Port and Local port fields. $COMMAND$ corresponds to the name of the script to be debugged.
Remote host	Specify URL of the host where remote debugging will take place.
Remote port	Specify the port number on the server side. Note that the number entered in this field, is automatically used in the `rdebug` command. As you type port number, the suggested command string changes accordingly.
Remote root folder	Specify the root directory on the server side, where the script to be debugged is located. This field defines mapping to the local root folder.
Local port	Specify the local port number. Note that the number entered in this field, is automatically used in the `rdebug` command. As you type the local port number, the suggested command string changes accordingly.
Local root folder	Specify the local root directory containing the script in question. Type the path, or click and find the desired root in the Select Path dialog box.

Common settings

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


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, IntelliJ IDEA 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 IntelliJ IDEA 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, IntelliJ IDEA 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 IntelliJ IDEA 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.

Before launch

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.

Item	Shortcut	Description
	`Alt+Insert`	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 IntelliJ IDEA yet, add its definition. For more information, see External tools and External tools settings. Run Another Configuration: select to execute another run/debug configuration and wait until it finishes before starting the current configuration. If you want to run several configurations in parallel, use a compound run/debug configuration. Build: select to compile the specified module. The Build Module command will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration. Build Project: select to compile the entire project. The Build Project command will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration. Build, no error check: the same as the Build option, but IntelliJ IDEA will try to start the run/debug configuration irrespective of the compilation results. Build Artifacts: select this option to build an artifact or artifacts. In the dialog that opens, select the artifact or artifacts that should be built. 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 Ant target: select this option to run an Ant target. In the dialog that opens, select the target to be run. 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 Maven Goal: select this option to run a Maven goal.

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. Upload files to Remote Host: select this option to have the application files automatically uploaded to the server according to the default server access configuration. Run Remote External Tool: adds a remote SSH external tool. Disconnect Data Source: select this option if you want to disrupt the connection to a data source before the run/debug configuration is run.
