Fusion Electronics: A MERN-Stack E-commerce Application

Welcome to Fusion Electronics, a MERN-Stack E-commerce Application! This project is a working demo of a full-stack web application that was built using the MERN stack (MongoDB, Express.js, React.js, Node.js). It aims to provide a comprehensive example of building a modern e-commerce platform, covering frontend user interface, backend server logic, database management, and integration with third-party libraries.

Introduction

This project is a demonstration of building an e-commerce application using the MERN stack, which consists of MongoDB (database), Express.js (server), React.js (frontend), and Node.js (runtime environment). The application allows users to browse products, add them to a shopping cart, proceed to checkout, and simulate the order processing. It includes basic validations for user inputs and simulates the checkout process on the backend.

Live Deployment

The application is deployed live on Vercel. You can access it at the following URL: Fusion Electronics.

The backend server is deployed on Render and can be accessed at the following URL: Fusion Electronics API.

Note: The backend server may take a few seconds to wake up if it has been inactive for a while. For your information, it is hosted on the free tier of Render, with 0.1 CPU and 512 MB of memory only, so it may take a bit longer to respond to requests, especially after periods of inactivity.

Getting Started

Prerequisites

Before running this project, ensure you have the following installed:

• Node.js (with npm)
• MongoDB (with either local or remote instance)
• Git

Installation

1. Clone the repository:

   git clone https://github.com/hoangsonww/MERN-Stack-Ecommerce-App.git
   cd MERN-Stack-Ecommerce-App  # Fix the path if necessary

2. Install project dependencies:

   # Install server (backend) dependencies
   cd backend
   npm install
   
   # Install client (frontend) dependencies
   cd ..
   npm install

3. Set up the backend:

   • Create a .env file in the backend/ directory and add the following environment variable (replace the URI with your MongoDB connection string):

     MONGO_URI=mongodb://localhost:27017/Ecommerce-Products
     JWT_SECRET=your_secret_key
     

     For your information, I am using MongoDB Atlas for this project. You can create a free account and get your connection string from there if you want to deploy the application to the cloud.

   • Ensure that your MongoDB server is running. If you're using Mac, you can start the MongoDB server with the following command:

   brew services start mongodb-community

   • Seed the database with sample data:

     cd backend/seed
     node productSeeds.js dev

   • Run the backend server: (first cd into the backend directory)

     cd ..
     npm start

4. Set up the frontend:

   • First, cd into the root directory if you are not already there:

     cd ..

     Or

     cd fullstack-ecommerce

   • Start the frontend development server:

     npm start

   • Note: The frontend server will run on http://localhost:3000 by default. If you encounter any errors when starting related to the react-credit-cards-2 package, it is OK to just ignore them as the application will still run correctly.

Running the Application

• Open your browser and navigate to http://localhost:3000 to view the application.

Testing the APIs

• Simply open your browser and navigate to http://localhost:5000/api/products to view the list of products.
• You can also change the sample data by navigating to backend/seed/productSeeds.js and modifying the data there.

Swagger API Documentation

• The backend server includes Swagger API documentation that can be accessed at http://localhost:5000/api-docs.
• Before accessing the above URL, ensure that the backend server is running.
• The Swagger UI provides a detailed overview of the API endpoints, request/response schemas, and example requests.
• If you have everything set up correctly, you should see the Swagger UI documentation page:

Deployment

To deploy the application:

• Configure deployment settings for both frontend (React) and backend (Node.js) according to your chosen hosting provider (e.g., AWS, Heroku, Netlify).

Containerization

This project can be containerized using Docker. First, ensure that Docker Desktop is running on your system. Then, to create a Docker image, run the following command:

docker compose up --build

This command will create a Docker image for the frontend and backend, and run the application in a containerized environment.
