This project contains a basic example of a game integration for Discord written in JavaScript, built for the Developing a User-Installable App tutorial.
Below is a basic overview of the project structure:
├── .env.sample -> sample .env file
├── app.js -> main entrypoint for the app
├── commands.js -> slash command payloads + helpers
├── game.js -> logic specific to the fake game
├── utils.js -> utility functions and enums
├── package.json
├── README.md
└── .gitignore
Configuring the app is covered in detail in the tutorial.
Before you start, you'll need to install NodeJS and create a Discord app with the proper configuration:
Click on the Installation page in your app's settings and go to the Default Install Settings section.
For user install:
applications.commands
For guild install:
applications.commandsbot(with Send Messages enabled)
This sample app uses a privilege intent to create a fake leaderboard. In production, you probably wouldn't need this.
Click on the Bot page in your app's settings and go to the Privileged Gateway Intents section.
Toggle Server Members Intent.
First clone the project:
git clone https://github.com/discord/user-install-example.git
Then navigate to its directory and install dependencies:
cd user-install-example
npm install
Fetch the credentials from your app's settings and add them to a .env file (see .env.sample for an example). You'll need your app ID (APP_ID), bot token (DISCORD_TOKEN), and public key (PUBLIC_KEY).
Fetching credentials is covered in detail in the tutorial.
🔑 Environment variables can be added to the
.envfile in Glitch or when developing locally, and in the Secrets tab in Replit (the lock icon on the left).
The commands for the example app are set up in commands.js. All of the commands in the ALL_COMMANDS array at the bottom of commands.js will be installed when you run the register command configured in package.json:
npm run register
After your credentials are added, go ahead and run the app:
node app.js
⚙️ A package like
nodemon, which watches for local changes and restarts your app, may be helpful while locally developing.
The project needs a public endpoint where Discord can send requests. To develop and test locally, you can use something like ngrok to tunnel HTTP traffic.
Install ngrok if you haven't already, then start listening on port 3000:
ngrok http 3000
You should see your connection open:
Tunnel Status online
Version 2.0/2.0
Web Interface http://127.0.0.1:4040
Forwarding http://1234-someurl.ngrok.io -> localhost:3000
Forwarding https://1234-someurl.ngrok.io -> localhost:3000
Connections ttl opn rt1 rt5 p50 p90
0 0 0.00 0.00 0.00 0.00
Copy the forwarding address that starts with https, in this case https://1234-someurl.ngrok.io, then go to your app's settings.
On the General Information tab, there will be an Interactions Endpoint URL. Paste your ngrok address there, and append /interactions to it (https://1234-someurl.ngrok.io/interactions in the example).
Click Save Changes, and your app should be ready to run 🚀
