Discord Proxy Bot (Rust)

A simple Discord bot built with Serenity framework that acts as a proxy, forwarding user queries to another service and returning the responses.

Features

• Slash command /bot that forwards user queries to a specified endpoint
• Dockerized for easy deployment
• Ready for DigitalOcean App Platform

Setup

Prerequisites

• Rust (latest stable)
• Discord Bot Token
• Endpoint URL for forwarding requests

Environment Variables

Create a .env file in the root directory with the following variables:

DISCORD_TOKEN=your_discord_bot_token
TARGET_URL=https://your-target-service.com/api/endpoint

Discord Bot Setup

1. Go to the Discord Developer Portal
2. Create a new application
3. Navigate to the "Bot" tab and create a bot
4. Enable the following Privileged Gateway Intents:
   • Message Content Intent
5. Copy the bot token and add it to your .env file
6. Use the OAuth2 URL Generator with the following scopes:
   • bot
   • applications.commands
7. Invite the bot to your server

Local Development

1. Clone this repository
2. Set up your .env file with the required variables
3. Run the bot:

cargo run

Building the Docker Image

docker build -t discord-proxy-bot .

Running with Docker

docker run -e DISCORD_TOKEN=your_token -e TARGET_URL=your_url discord-proxy-bot

Deploying to DigitalOcean App Platform

1. Fork or push this repository to GitHub
2. In the DigitalOcean dashboard, create a new App
3. Select your repository
4. Configure the environment variables:
   • DISCORD_TOKEN: Your Discord bot token
   • TARGET_URL: The URL to forward requests to
5. Deploy the app

Using the App Spec

You can also use the included app.yaml file to deploy directly with the DigitalOcean CLI:

doctl apps create --spec app.yaml

Usage

Once the bot is running and added to your server, you can use the slash command:

/bot your query here

The bot will forward "your query here" to the target service and respond with the result.

Expected API Response Format

The target service should return a JSON response with the following structure:

{
  "response": "This is the response text that will be sent back to Discord."
}

Adding Health Check (Optional)

For a more robust deployment, you can add a simple health check endpoint:

1. Add the warp package to your dependencies
2. Implement a simple HTTP server with a /health endpoint
3. Make sure your app listens on the port specified in the App Platform config (default: 8080)
