Export Your Realm Application

To enable wire protocol connections with realm-cli you need to export an application directory for your application.

You can export your application from the Import/Export App tab of the Deploy page in the Realm UI, or by running the following command from an authenticated instance of realm-cli:

realm-cli export --app-id=<App ID>

The config.json configuration file in the linked cluster’s service directory configures wire protocol connections.

In the configuration file, set config.wireProtocolEnabled to true:

  "config": { "wireProtocolEnabled": true }

Import Your Application Directory

Save the cluster configuration file, then navigate to the root of the exported application directory and run the following command to import the directory:

realm-cli import
