Wipro-NGA-MERN-24th-Oct

Enterprise-grade MERN Stack learning repository created as part of the
Wipro NGA (Next Gen Associate) Program – Oct Batch.

This repository captures a structured, day-wise progression from web fundamentals to full-stack application development and is actively used as a trainer reference, mentoring base, and foundation accelerator for early-career engineers.

🎯 Program Objective

To enable learners to:

• Build strong frontend fundamentals
• Understand modern JavaScript & TypeScript
• Develop RESTful backends using Node.js & Express
• Work with SQL & MongoDB
• Apply real-time communication, authentication, validation, and middleware
• Transition confidently into full-stack MERN development

---

🛠️ Tech Stack

Frontend

• HTML5, CSS3
• Bootstrap
• JavaScript (ES6+)
• React (CLI-based setup)

Backend

• Node.js
• Express.js
• REST APIs
• JSON Server (Mock Backend)
• Socket.IO (Real-time communication)

Databases

• MySQL
• MongoDB

Validation & Security

• Client-side validation
• Joi validation
• Middleware-based request handling
• Authentication concepts

---

🧱 Architecture Overview

The repository follows a trainer-driven modular learning architecture:

• Day-wise folders → Progressive concept buildup
• Frontend-first approach → HTML → JS → React
• Backend layering → Node → Express → Middleware → APIs
• Data handling → SQL → MongoDB → Validation
• Real-world patterns → Auth, sockets, REST, validation

Each folder represents a teachable unit that can be independently reused for classroom delivery, mentoring, or revision.
