Custom Emitters

Watching Process

As shown in the first listener tutorial, we can have custom emitters.
Listeners can run on more than Akairo-related things.
To add a custom emitter, use the setEmitters method available on the listener handler.

this.listenerHandler.setEmitters({
  process: process,
  anything: youWant
});

Note: You have to call setEmitters before load or loadAll so that Akairo will be able to resolve your emitters.

The key will be the emitter's name, and the value is the emitter itself.
Now, we can use a listener on the process:

import { Listener } from "discord-akairo";

export default class UnhandledRejectionListener extends Listener {
  constructor() {
    super("unhandledRejection", {
      event: "unhandledRejection",
      emitter: "process"
    });
  }

  exec(error: Error): void {
    console.error(error);
  }
}
