Controllers

In Sword, a controller is an entry point to your application.

In practice, a controller receives external events or requests and transforms them into calls to your modules' internal logic.

Some examples:

• A web controller that receives an HTTP request.
• A Socket.IO controller that listens for real-time events.

How are they registered?

Controllers are registered within a module using register_controllers.

impl Module for UsersModule {
    fn register_controllers(controllers: &ControllerRegistry) {
        controllers.register::<UsersController>();
    }
}

This is the standard flow: each module declares its controllers, and Application::builder().with_module::<...>() takes care of the rest.

Available Controller Types

• Web Controllers
• Socket.IO Controllers
• gRPC Controllers
