Course Selling App (Backend)

This repository contains the backend implementation of a course selling app built using Node.js, Express, and MongoDB. The API enables admins to manage courses, including creating, updating, deleting, and archiving courses to a deleted records collection.

Features

1. Admin Authentication:

   • Signup and login for admins with secure password hashing using bcrypt.
   • Authentication using JWT tokens for secure access.

2. Course Management:

   • Create new courses.
   • Update existing courses.
   • Delete courses and transfer them to a separate DeletedCourses collection.

3. Middleware:

   • Admin middleware to protect routes and ensure only authenticated admins can access them.

Setup Instructions

Prerequisites

• Node.js installed (v16 or later recommended).
• MongoDB database instance (local or cloud-based).
• Environment variables configured in a .env file.

Installation

1. Clone the repository:

   git clone <repository-url>
