Course Management System

This is a simple Course Management System built with Node.js, Express, and MongoDB. It provides separate routes for administrators and users, allowing course creation, user registration, and course purchases.

Features

• User authentication (signup and signin)
• Admin authentication (signup and signin)
• Course creation and listing (admin only)
• Course purchasing (users)
• Viewing purchased courses (users)

Setup

Prerequisites

Ensure you have Node.js installed on your system. You can download it from nodejs.org.

Installation

1. Clone the repository:

   git clone <repository-url>

2. Navigate to the project directory:

   cd <project-directory>

3. Install the required dependencies:

   npm install

Database Setup

1. Set up your MongoDB database:

   • This project uses MongoDB Atlas. Make sure you have a MongoDB Atlas account and a cluster set up.
   • In the db/index.js file, replace the connection string with your own:

     mongoose.connect("mongodb+srv://<username>:<password>@<your-cluster-url>/<database-name>")

   • Replace <username>, <password>, <your-cluster-url>, and <database-name> with your actual MongoDB Atlas credentials and chosen database name.

2. Configure the JWT secret:

   • The project uses a hardcoded JWT secret. In a production environment, it's recommended to use an environment variable instead. You can set it up in a .env file:

     JWT_SECRET=manish12

Running the Server

Start the server with:

node index.js

The server will run on port 3000 by default.

Database Schema

The project uses the following MongoDB schemas:

Admin Schema

const AdminSchema = new mongoose.Schema({
  username: String,
  password: String
});

Course Schema

const CourseSchema = new mongoose.Schema({
  title: String,
  description: String,
  price: Number,
  imgLink: String
});

User Schema

const UserSchema = new mongoose.Schema({
  username: String,
  password: String,
  courses: [CourseSchema]
});
