GraphQL Chat App

Welcome to my GraphQL chat application, a real-time messaging web application built with modern web technologies. This project demonstrates my skills as a full-stack developer, focusing on creating a secure and scalable chat application.

Features

• Real-Time Messaging: Instant messaging with GraphQL subscriptions.
• Backend: NestJS with a GraphQL API for handling CRUD operations and real-time communication.
• Distributed Messaging: Redis integration for handling a large number of concurrent users and messages.
• Data Persistence: MongoDB for efficient storage of chat data and user information.
• Frontend: React with Material UI for a responsive and visually appealing user interface.
• State Management: Apollo Client for interacting with the GraphQL API and caching data.
• User Profile: Ability to update user icons, stored securely on Amazon S3.
• Deployment: Deployed on AWS Elastic Beanstalk and Amplify with HTTPS configuration for security.

Getting Started

To get started with this project, clone the repository and install the dependencies:

• git clone https://github.com/LouisC00/chatter-backend.git
• cd chatter-backend

Running the Application

To run the application in development mode, use the following commands:

Start the backend server

• cd chatter-backend
• pnpm install

Environment Variables

Create a .env file in the root of the backend directory and add the following variables:

• MONGODB_URI: The URI for connecting to your MongoDB database.
• DB_NAME: The name of your database.
• JWT_SECRET: A secret key for JWT authentication.
• JWT_EXPIRATION: The expiration time for the JWT token (e.g., 1d for 1 day).
• PORT: The port number on which the backend server should run.
• AWS_ACCESS_KEY: Your AWS access key.
• AWS_SECRET_ACCESS_KEY: Your AWS secret access key.
• AWS_REGION: The AWS region for your services.

Example /sample.env:

MONGODB_URI=mongodb://localhost:27017
