Ping Pong

Now that your bot is receiving messages, you can respond to them.

Launching the Proxy​

The proxy will handle all of your outgoing HTTP requests to Discord. To launch the Spectacles proxy:

docker run \
    --rm -it \
    --network host \
    spectacles/proxy:latest

Installing Dependencies​

Add the Spectacles proxy client library.

npm i @spectacles/proxy

Modifying The Handler​

Update your command handler to send a "pong" back when it receives a "ping".

note

Replace your bot token with your Discord bot token.

import { Redis } from '@spectacles/brokers';
import Rest from '@spectacles/proxy';
import RedisClient from 'ioredis';

const client = new RedisClient();
const gatewayBroker = new Redis('gateway', client);
const proxyBroker = new Redis('proxy', client);
const rest = new Rest(proxyBroker, 'your bot token');

gatewayBroker.on('MESSAGE_CREATE', async (msg, { ack }) => {
    await ack();
    console.log(msg);

    if (msg.content === 'ping') {
        await rest.post(`/channels/${msg.channel_id}/messages`, { content: 'pong' });
    }
});

gatewayBroker.subscribe('MESSAGE_CREATE');

Next Steps​

You have a fully functioning and scalable Discord bot now. The possibilities are endless:

  • Continue developing your command handler
  • Add a completely new application (a website?)
