A Discord Music Bot written in TypeScript using Sapphire, discord.js, Next.js and React

System dependencies

Node.js LTS or latest
Java 13 (other versions have some issues with Lavalink)

Setup bot

Create an application.yml file root folder.

Download the latest Lavalink jar from here and also place it in the root folder.

PostgreSQL

Linux

Either from the official site or follow the tutorial for your distro.

MacOS

Get brew, then enter 'brew install postgresql'.

Windows

Getting Postgres and Prisma to work together on Windows is not worth the hassle. Create an account on heroku and follow these steps:

Open the dashboard and click on 'New' > 'Create new app', give it a name and select the closest region to you then click on 'Create app'.
Go to 'Resources' tab, under 'Add-ons' search for 'Heroku Postgres' and select it. Click 'Submit Order Form' and then do the same step again (create another postgres instance).
Click on each 'Heroku Postgres' addon you created, go to 'Settings' tab > Database Credentials > View Credentials and copy the each one's URI to either DATABASE_URL or SHADOW_DB_URL in the .env file you will be creating in the settings section.
Done!

Redis

MacOS

brew install redis.

Windows

Download from here.

Linux

Follow the instructions here.

Settings (env)

Create a .env file in the root directory and copy the contents of .env.example to it. Note: if you are not hosting postgres on Heroku you do not need the SHADOW_DB_URL variable.

Gif features

If you have no use in the gif commands, leave everything under 'Other APIs' empty. Same applies for Twitch, everything else is needed.

DB URL

Change 'john' to your pc username and 'doe' to some password, or set the name and password you created when you installed Postgres.

Bot Token

Generate a token in your Discord developer portal.

Next Auth

You can leave everything as is, just change 'yourclientid' in NEXT_PUBLIC_INVITE_URL to your Discord bot id.

Next Auth Discord Provider

Go to the OAuth2 tab in the developer portal, copy the Client ID to DISCORD_CLIENT_ID and generate a secret to place in DISCORD_CLIENT_SECRET. Also, set this as the URL under 'Redirects': http://localhost:3000/api/auth/callback/discord.

Lavalink

You can leave this as long as the values match your application.yml.

Spotify and Twitch

Create an application in each platform's developer portal and paste the relevant values.

Running the bot

If you followed everything right, hit npm i in the root folder. When it finishes make sure prisma didn't error.
Open a separate terminal in the root folder and run 'java -jar Lavalink.jar'.
Wait a few seconds and hit npm run dev.
If everything works, your bot should be running and the dashboard should be on localhost:3000.
Enjoy!
