In this area, choose the platform for which the application is intended. Depending on your choice, IntelliJ IDEA will run the bundler with

|Browser for debugging||In debugging React Native applications, IntelliJ IDEA relies on the Chrome runtime, which is used by React Native itself. You can also use DevTools together with IntelliJ IDEA. When you initiate a debugging session, IntelliJ IDEA starts a new Chrome instance and attaches to it. If you don’t want to see any new Chrome windows, use the Chrome Headless mode.|
In this field, specify the host where the bundler runs, the default value is localhost.
If you are using Expo, you may need to change the default bundler host to ensure successful connection with the debugger. This connection may fail because IntelliJ IDEA by default uses localhost to start debugging while Expo expects 127.0.0.1 or an external IP address depending on what is selected in Connection field of the Metro bundler configuration. See Debugging a React Native application that uses Expo for details.
In this field, specify the port on which the bundler runs.
|React Native package||In this field, specify the path to react-native-cli.|
|Working directory||specify the working directory of the application. By default, the field shows the project root folder.|

When you edit a run configuration (but not a run configuration template), you can specify the following options:
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, IntelliJ IDEA 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 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.
|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.|
|View and edit the template (that is, the default run/debug configuration settings). The templates are displayed under the Templates node and used for newly created configurations.|
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 button to sort configurations in the alphabetical order.|
In this area you can specify tasks that must 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:
|Alt+Delete||Click this icon to remove the selected task from the list.|
|Enter||Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.|

|Show this page||Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.|
|Activate tool window|
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.
