What is this

This repo contains the code for https://twitch.discord.barrycarlyon.co.uk, a Twitch Go Live Notification System for Discord

Languages

It's written in NodeJS

Documentation

It uses the following API reference documentation

Twitch OAuth authorization code flow for Authentication
Twitch Eventsub for Channel/Stream Notifications
Discord oAuth2 for Discord webhook Setup and Login
Discord Webhooks for talking to Webhooks

What does it look like?

Running it yourself

This system uses MySQL as a Database backend and Redis for session handling and message brokering between the two services

Import sql/barrys_discord_twitch.sql to your MySQL database
Copy .env.sample to .env
Revise the settings within, for your Discord Application and Twitch Applications.
Revise that database access settings
Make sure to update the URLs, and Twitch EventSub
npm install

It's expected to your PM2 as a process manager. So you can either use PM2 or run the two jobs another way

pm2 start app.json

or start the two jobs manually

node server.js
node utils/runner.js

Using TwitchCLI to test

You can use the Twitch-cli to test your Eventsub callback see https://github.com/twitchdev/twitch-cli/ and look under Events

Example:

twitch event verify-subscription stream.online -s "THESECRETISCOOL" -F "https://twitch.discord.barrycarlyon.co.uk/eventsub/"

You would naturally swap the URL to the URL for your instance of the project.

Nginx and Cookie Security

This is an example, so doesn't contain all the best security practices. Since this uses cookies to manage logins you should change the session code to something like. And the paired app.user to sanity check/enforce the right domain for cookies to behave

app.use(session({
    store: new RedisStore({
        client: redis_client
    }),
    secret,
    resave: true,
    saveUninitialized: false,
    cookie: {
        secure: true,
        httpOnly: true,
        domain: config.server.domain
    },
    rolling: true
}));

app.use((req, res, next) => {
    if (req.hostname != config.server.domain) {
        res.redirect(`https://${config.server.domain}/${req.originalUrl}`);
        return;
    }

Change the domain as needed!

If you are putting this nodeJS HTTP server beind NGINX, your NGINX declartion for the location will need additional fields:

server {
    listen IPv4:443;
    listen [::]:443;

    server_name example.com;
    root /some/path/to/files;

    ssl on;
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    location / {
        # Cookie Flags
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        # Cookie Flags
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        # Other

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;

        proxy_pass http://this_server_relay;
    }
}

upstream this_server_relay {
    server 127.0.0.1:5000;
    keepalive 8;
}
