Getting Started app for Discord

This project contains a basic rock-paper-scissors-style Discord app written in JavaScript, built for the getting started guide.

Demo of app

✨ A version of this code is also hosted on Glitch 🎏.

Running app locally

Before you start, you’ll need to create a Discord app with the proper permissions:

  • applications.commands
  • bot (with Send Messages enabled)

Configuring the app is covered in detail in the getting started guide.

Setup project

First clone the project:

git clone https://github.com/discord/discord-example-app.git

Then navigate to its directory and install dependencies:

cd discord-getting-started
npm install

Get app credentials

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), server ID (GUILD_ID), bot token (DISCORD_TOKEN), and public key (PUBLIC_KEY).

Fetching credentials is covered in detail in the getting started guide.

Run the app

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.

Set up interactivity

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 🚀
