In debugging React Native applications, GoLand relies on the Chrome runtime, which is used by React Native itself. You can also use DevTools together with GoLand. When you initiate a debugging session, GoLand starts a new Chrome instance and attaches to it.
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 GoLand 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.
In this field, specify the port on which the bundler runs.
In this field, specify the Node.js interpreter to use.
If you choose the Project alias, GoLand will automatically use the project default interpreter from the Node interpreter field . In most cases, GoLand detects the project default interpreter and fills in the field itself.
You can also choose another configured local interpreter or click and configure a new one.

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, GoLand 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 GoLand 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.
