# E-Learning SaaS Platform Backend

This is the backend for an E-Learning SaaS platform designed to provide hands-on experience for frontend, backend, and full-stack software developers. The platform allows users to work on dummy and real projects, receive mentorship, and get paid for successfully completing real projects.

## Getting Started

### Prerequisites

- Node.js
- Docker (optional, for running database in a container)

### Installation

1. Clone the repository:

   ```sh
   git clone https://github.com/your-repo/backend.git
   cd backend
   ```

2. Install dependencies:

   npm install

3. Create a .env file in the root directory with the following content:

   PORT=3000
   DB_HOST=localhost
   DB_USER=root
   DB_PASSWORD=password
   DB_NAME=elearning
   DB_PORT=3306

Running the Application

1. Start the application:

   npm start

2. The server should now be running at http://localhost:3000.

Running Tests

1. Run the tests:

   npm test

Database Migrations and Seeds

1. Create the database:

   npm run db:create

2. Run migrations:

   npm run migration:lts

3. Seed the database:

   npm run seed:all

Docker Commands
