Amazon Clone Backend

This project is the backend service for an Amazon clone application. It handles user authentication, song management (CRUD operations), and other essential features using Node.js, SQL, and Prisma.

Features

• User Authentication: Signup and Signin with JWT-based authentication.
• CRUD for Songs: Create, read, update, and delete song entries.
• Password Security: Secure password hashing using bcrypt.
• Prisma ORM: Simplifies database operations with SQL databases.
• JWT Tokens: Used for user authentication and authorization.

Technologies Used

• Node.js: Backend runtime environment.
• Express: Web framework for Node.js.
• Prisma: ORM for interacting with SQL databases.
• SQL Database: MySQL or SQLite (or any SQL-compatible DB).
• JWT: For managing authentication tokens.
• Bcrypt: For password encryption.

Getting Started

Prerequisites

• Node.js installed.
• A SQL Database (e.g., MySQL, SQLite, etc.).
• Prisma installed and configured.
• npm or yarn for package management.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/amazon-clone-backend.git
   cd amazon-clone-backend

2. Install dependencies:

   npm install

3. Set up environment variables: Create a .env file:

   touch .env

   Add the following variables to the .env file:

   DATABASE_URL="mysql://user:password@localhost:3306/your-database"
   JWT_SECRET="your-secret-key"

4. Set up Prisma and the database: Initialize Prisma and apply migrations:

   npx prisma init
   npx prisma migrate dev --name init

5. Start the server:

   npm start

   The server will run on http://localhost:3000.
