MERN Backend Starter Template

Tech Stack

Overview

This repository provides a MERN backend starter template featuring Express and MongoDB. It includes authentication (JWT-based) and authorization (role-based access control), making it easy to start building secure RESTful APIs for your application.

Features

• Express for handling API routes and middleware.
• MongoDB for database integration using Mongoose ORM.
• JWT Authentication to manage user login and sessions.
• Role-based Authorization to control access to certain routes (e.g., Admin, User).
• CORS support for development environments.
• Configured with Environment Variables for sensitive data management.

Prerequisites

Before you begin, ensure that you have the following tools installed:

• Node.js (v12 or higher)
• npm or yarn
• A MongoDB instance (local or cloud, e.g., MongoDB Atlas)
