🤖 Create your Discord bot by using TypeScript and decorators!

#typescript #discord #tutorial #javascript

Hello all, Today, I will demonstrate how to create a discord bot using typescript and manage it easily with discordx.

I will show you the fastest way to setup your bot in this post, then in a subsequent post I will show you how to set it all up from scratch.

before we start, I assume you have some familiarity with discord bots, typescript decorators, and node.js.

Let's start

Step 1: Clone starter bot



git clone https://github.com/oceanroleplay/discord.ts-example



cd discord.ts-example

Step 2: Install dependencies



npm install

Step 3: Set bot token
In case you don't have a bot token yet, you can get it from the Discord developer portal



set BOT_TOKEN=<your bot token>

Step 4: build your bot



npm run build

Step 5: Start your bot



npm run start

And you're done, everything has been done for you! 🚀

What's behind?

Steps above seem straight forward, let's discuss in depth.

we are using package called discordx to create the bot with decorators.

📔Decorators

There is a whole system that allows you to implement complex slash/simple commands and handle interactions like button, select menu, contextmenu etc.

General

Commands

GUI Interactions

Here are the source files for the project and important configurations
