SideHub_bot

Overview

This project demonstrates running multiple bot instances concurrently in a single Node.js application. Each bot instance is configurable via environment variables and runs its own HTTP server while sharing common resources such as the Moralis connection.

Features

• Run two (or more) bot instances concurrently.
• Shared Moralis connection using static properties to prevent duplicate initializations.
• Each bot has its own HTTP server configuration.
• Configurable via a single .env file.

Prerequisites

• Node.js (v14 or later)
• npm or yarn
• A running MongoDB instance
• A running Redis instance
• Valid credentials for Moralis (if used)

Setup Instructions

1. Clone the repository:

   git clone https://github.com/AmanUpadhyay1609/TG_SIDEHUB.git
   cd SideHub_bot

2. Install dependencies:

   npm install

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

   # Bot 1 Configuration
   BOT_TOKEN=YOUR_BOT_TOKEN
   BOT_SERVER_HOST=YOUR_BOT_SERVER_HOST
   BOT_SECRET=your_secret
   BOT_MODE=polling    # or "webhook"
   BOT_ALLOWED_UPDATES=message,callback_query
   HTTP_SERVER_HOST=localhost
   HTTP_SERVER_PORT=3003
   MORALIS_API_KEY=YOUR_MORALIS_API_KEY
   MONGO_URL=mongodb://localhost:27017/multichain-bot
   REDIS_URL=redis://localhost:6379
   BOT_USERNAME=YOUR_BOT_USERNAME
   CHAIN_NAME=solana
   WEBHOOK_URL=YOUR_WEBHOOK_URL
   WEB3_BACKEND_URL='https://api.sidebot.xyz' #Sidebot official Backend url
   
   # Bot 2 Configuration
   BOT_TOKEN_2=YOUR_BOT_TOKEN_2
   BOT_SERVER_HOST_2=YOUR_BOT_SERVER_HOST_2
   BOT_SECRET_2=your_secret_2
   BOT_MODE_2=polling    # or "webhook"
   BOT_ALLOWED_UPDATES=message,callback_query
   HTTP_SERVER_HOST_2=localhost
   HTTP_SERVER_PORT_2=3003   # Ensure this port is different from Bot 1 if needed
   MORALIS_API_KEY_2=YOUR_SECOND_MORALIS_API_KEY
   MONGO_URL_2=YOUR_MONGO_URL   # Optional: can be the same as Bot 1
   REDIS_URL_2=YOUR_REDIS_URL   # Optional: can be the same as Bot 1
   BOT_USERNAME_2=YOUR_BOT_USERNAME_2
   CHAIN_NAME_2=multichain
   WEBHOOK_URL_2=YOUR_WEBHOOK_URL_2
   WEB3_BACKEND_URL_2='https://api.sidebot.xyz'  #Sidebot official Backend url

   Note: Ensure that HTTP_SERVER_PORT and HTTP_SERVER_PORT_2 are unique if both bots start their own HTTP server.

4. Build and run the project:

   • To compile the TypeScript code:

     npx tsc

   • To run the compiled output:

     node dist/index.js

   • Alternatively, run directly with ts-node:

     npx ts-node src/index.ts

How It Works

• The project instantiates two BotApplication instances using different configuration objects (config and config_2).

• HTTP Server Configuration:

  • Each bot instance creates its own HTTP server which listens on the configured port.

• Moralis Connection:

  • A shared static property (isMoralisConnected) in BotApplication ensures that Moralis is only initialized once across all instances.
  • moralisInitPromise handles concurrent calls to Moralis initialization by sharing the promise.

• Bot Modes:

  • The bots support both polling and webhook modes, configurable via environment variables.

Adding Additional Bot Instances

To add another bot instance (e.g., Bot 3):

1. Create a new configuration object (e.g., config_3) in the code and add corresponding environment variables in your .env file (e.g., BOT_TOKEN_3, HTTP_SERVER_PORT_3, etc.).

2. Instantiate the new bot instance:

   const botApp3 = new BotApplication(config_3);
   botApp3.start().catch(error => {
     console.error("Fatal error:", error);
     process.exit(1);
   });

Troubleshooting

• Port Conflicts:

  • Make sure each bot instance is configured to use a unique HTTP_SERVER_PORT.

• Environment Variables:

  • Verify that all required variables are properly set in the .env file.

• Moralis Issues:

  • If you encounter errors related to Moralis, ensure you have a valid API key and that only one connection is established via the shared static properties in BotApplication.
