Project Information

• This project is a small version of any Exchange application like Binance, Backpack CoinDTX etc. Here I show the Realtime price, chart, trade, asks and bids of any currency like Bitcoin, Solana, Ethereum and many more.
• Here I try to implement my own backend Service for trade and RealTime logic. Use can Also see the Backend Architecture here.

for Reference I use the docs of Binance

Setup Guide

This Project contains following services and folders:

• Frontend: A Next application to see all data of Exchange and GUI for Trading.
• api-Server: An Express API Server for REST API's to interact with frontend.
• tradeEngine: A highly Scalabe NodeJs server which Contain the core Logic to perform all RealTime trade by using the Message Queue for high performance.
• wsSocketServer: A Web Socket server responsible for Realtime communication between the client and server. To scale the Web Socket I use the PUB/SUBS architecture.
• DataBase: A timeScale PostgesQL DataBase to store the market data and Trade information.
• Redis: Use to implement a Message queue and a Publisher/Subscriber architecture.

Local Setup

• This repo is create with TurboRepo. Because TurboRepo provides efficient monorepo management, enabling faster builds and streamlined workflows by sharing dependencies, caching results, and optimizing project configurations.

1. Run npm run build in root folder to build all the 5 serivces. TurboRepo start all service simultaneously.
2. SetUp all .env files in all service folders.
3. Run docker-compose up command to run the Redis and PostgresQL database in docker container.
4. Run npm run dev in root folder to up all service in development enviroment.

At this point following services would be up and running:

S.No	Service	PORT
1	Frontend	:3000
2	Api server	:4000
3	Web Socket server	:9000
