Controllers
Controllers are responsible for handling incoming messages and returning replies. In order to create a basic controller, we use classes and decorator. Decorators associate classes with required metadata and enable Fastwa to map all interactions (tie interactions to the corresponding controllers).
Fastwa employs two different options for manipulating replies:
| Standard (recommended) | Using this built-in method, when it returns a JavaScript primitive type (e.g., string), however, Fastwa will send just the value. This makes messages handling simple: just return the value, and Fastwa takes care of the rest. |
| Platform-specific | We can use the socket instance, which can be injected using the @Socket() decorator. With this approach, you have the ability to use the native reply methods exposed by that object. For example, you can send a message using code like this.sock.sendMessage(). |
Socket
Occasionally, you may want to have a direct access to the native, baileys socket instance. You can use the @Socket() decorator. Fastwa will automatically assign the socket instance to this property once it is ready to use.

Good to know: The
@Socket()decorator is imported from the@fastwa/commonpackage.
