Welcome to unlock-protocol-discord-bot 👋

A Discord bot which prompts the user to enter their DID, and creates a new challenge for them.

Whats included

• Discord bot w/ docker container in /bot
• API server RedwoodJS API in /api
• (incomplete) Frontend RedwoodJS web app in /web

Local Development

Setup the backend + frontend

yarn

# Initialize SQL-lite and perform initial migrations
yarn rw db save
yarn rw db up

# Start the API service and Frontend
yarn rw dev

Start the bot

cd bot && yarn
yarn start

Going to Production

The easiest way to deploy is using Vercel for the frontend and backend, and Heroku for the bot and postgres database. Hosting this way is free, and can be setup in about 10 minutes.

In order to collect all the required environment variables, you'll need to deploy all three parts (bot, FE+BE, discord app), and go back and update as necessary.

Vercel - Backend + Frontend

Point vercel to your repo, and deploy. Redwood build commands should be auto-configured.

Update the environment variables for what you see in the root .env file. The only new one is DATABASE_URL which you need from your Heroku database in the next step.

Heroku - Bot

Heroku doesn't like apps that aren't in the root folder. To get around this, I added a heroku-prebuild script which installs the bot dependencies. The Procfile runs the bot.js

Once deployed, head to the "Resources" tab, turn off the web Dyno, and turn on the worker Dyno. This Dyno is defined in the repo root Procfile.

Update the environment variables in "Settings" tab to reflect what you see in the .env here.

Add a new postgres add-on and add the url to the Vercel environment.

Discord

Create a new application at https://discord.com/developers. Don't worry about naming here.

Now in your app, navigate to "Bot" and create a bot. Choose a username and Icon for your bot here.

Leave "Bot Permissions" alone.

Copy the TOKEN and add it to your bot app.

Now add the bot to your server. In the Discord Application, in "General Information", copy the CLIENT ID. Insert it in this URL, and have the server administrator open it.

# Add the bot with role management permissions
https://discord.com/oauth2/authorize?client_id=<clientID>&scope=bot&permissions=268435456

Docker option

If you want to avoid Heroku for the bot, you can use docker. If you've made changes to the bot, you'll need to generate a new Docker image.

# Build
docker build -t <your username>/unlock-protocol-discord-bot .

# Test it out
docker run -p 8080:8080 -d <your username>/unlock-protocol-discord-bot

# Publish it when ready!

When you're ready to host the container, clone this repo on your server and navigate to this package. If you published your own version, the update the image name in docker-compose.yml. Be sure to update your .env file on the new machine as well.

# Load the .env file
source .env

# Start in "detached" mode
docker-compose up -d

Notes

• If you have permissions errors, try giving the bot a higher role. Bots can only give roles to members in a lower position than their own highest role. See https://discord.com/developers/docs/topics/permissions#permission-hierarchy
• Helpful discord docs for making a "emoji-reaction" menu https://discordjs.guide/popular-topics/reactions.html#awaiting-reactions
