Basic listeners setup

Listeners are a way of getting events and running code on them

this guide assumes that you are already using the intro bot

//mod.ts
//Set the directory of the listener handler
...
    listenerHandler: NaticoListenerHandler = new NaticoListenerHandler(this, {
        directory: './listeners',
    });

    async start(token: string) {
        //Set the emitters
        //Emitter must be set before loading any listeners otherwise it will cause errors
        this.listenerHandler.setEmitters({
            commandHandler: this.commandHandler,
        });
        //Loading the stuff
        await this.listenerHandler.loadALL();
        await this.commandHandler.loadALL();
        return this.login(token);
    }
...

Creating a listener#

//listeners/ready.ts
import { NaticoListener } from '../deps.ts';
export default class ready extends NaticoListener {
    constructor() {
        super('ready', {
            //The emitter of the event
            emitter: 'client',
            //THe event your listening for
            event: 'ready',
        });
    }

    exec() {
        console.log('Bot has started');
    }
}

This a listener for the command handler but you can also listen to other events, For example the commandStarted event:

import {
    ConvertedOptions,
    discordenoMessage,
    NaticoCommand,
    NaticoListener,
} from '../deps.ts';
export default class commandStarted extends NaticoListener {
    constructor() {
        super('commandStarted', {
            //In this example we are using the commandHandler that was specified in the mod.ts
            emitter: 'commandHandler',
            event: 'commandStarted',
        });
    }

    exec(
        message: discordenoMessage,
        command: NaticoCommand,
        args: ConvertedOptions
    ) {
        console.log('command:', command.id, 'started with args', args);
    }
}
