Setup

Wrangler Install & Login

To install wrangler, ensure you have npm installed, preferably using a Node version manager like Volta or nvm to avoid permission issues or to easily change Node.js versions, then run:

$ npm install -g wrangler

$ wrangler login

Create Discord Bot

To start, you need to create a discord app through the Discord Developer Dashboard:

Visit https://discord.com/developers/applications
Click New Application, and choose a name
Copy your Application ID and Public Key, and put them in the file wrangler.toml.
Now click on the Bot tab on the left sidebar, and create a bot! You can choose the same name as your app.
Grab the token for your bot, and store it somewhere safe. (For security reasons, you can only view your bot token once. If you misplace your token, you'll have to generate a new one.)

DISCORD_APPLICATION_ID = "YOUR_DISCORD_APPLICATION_ID"
DISCORD_PUBLIC_KEY = "YOUR_DISCORD_PUBLIC_KEY"
