Build A Bot (DiscordJS) — Javascript Chatbots made easy


There is not much that you need to start writing a bot for Discord using Javascript and while you could theoretically compose everything with copy and paste code snippets written by other people, I highly suggest some prior Javascript knowledge. Here is what you need apart from that.

  • A Discord Account & (desktop or web) Client
  • A Discord Server with “manage server” permission
  • Basic Terminal KnowHow
  • NodeJS version 10 or higher

First Steps — Discord Developer Portal

To write and use a bot, you need to register it as a new application/bot user with your Discord account. Go to the Discord Developers Portal (sign in) and create a “New Application”.

Project Setup

To get you started, I have prepared a small setup with a few simple commands and the basics on GitHub to start your development with the most useful default tools. You can grab the code from my repository and put it in a new folder for your own project.


The initial code, diving into DiscordJS

Without changing a single line of code, you could now start the bot by either calling node src/index.js to execute the file or run the script from the package.json file npm start which basically does the same.

1) ping

2) check the prefix

3) !who am I

4) !whois asking?

Wrapping up

I think we’ve covered a lot of ground here today and you learned a few basic commands and ways to interact with user messages in addition to the setup process using the discord developer portal.
