Real-time Database System using Node.js and Socket.io

This project is a tutorial on how to create a real-time database system using Node.js and Socket.io, similar to Firebase. The tutorial covers subscribing to single documents, collections, and sub-collections using a query.

Getting Started

YouTube Video is not a bad place to start

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Node.js npm Socket.io Express

Installing

1. Clone the repository

git clone https://github.com/aawssm/realtime-socketio.git

2. Install the dependencies

npm install

3. Start the server

npm start

The server will start on port 3000. You can change the port number in the server.js file.

TODO

• Real-time updates for a single document
• Real-time updates for a collection of documents
• Real-time updates for a query of a collection
• Add a persistent database (any SQL NoSQL)
• Optimize the query comparison function
• Add Redis for horizontal scaling
• Add additional filtering logic to optimize emit events
• Add other techniques for client-side and server-side optimization: Techniques such as pagination, caching, incremental updates, batching updates, and aggregation can be added to improve the performance and functionality of the project.

Built With

• Node.js - JavaScript runtime
• Socket.io - Real-time communication engine
• Express - Web application framework for Node.js
