 For automated component registry, [`react_component`](../api/view-helpers-api.md#react_component) and [`react_component_hash`](../api/view-helpers-api.md#react_component_hash) view helper method tries to load generated bundle for component from the generated directory automatically per `auto_load_bundle` option. `auto_load_bundle` option in `config/initializers/react_on_rails` configures the default value that will be passed to component helpers. The default is `false`, and the parameter can be passed explicitly for each call.

 ### Server Rendering and Client Rendering Components
 
-If server rendering is enabled, the component will be registered for usage both in server and client rendering. To have separate definitions for client and server rendering, name the component files `ComponentName.server.jsx` and `ComponentName.client.jsx`. The `ComponentName.server.jsx` file will be used for server rendering and the `ComponentName.client.jsx` file for client rendering. If you don't want the component rendered on the server, you should only have the `ComponentName.client.jsx` file.

 Once generated, all server entrypoints will be imported into a file named `[ReactOnRails.configuration.server_bundle_js_file]-generated.js`, which in turn will be imported into a source file named the same as `ReactOnRails.configuration.server_bundle_js_file`. If your server bundling logic is such that your server bundle source entrypoint is not named the same as your `ReactOnRails.configuration.server_bundle_js_file` and changing it would be difficult, please let us know.
