MERN Stack Training in Nepal — Complete Guide
MERN stands for MongoDB, Express, React, and Node.js — the most popular JavaScript full-stack combination for web apps. Digital Pathshala’s MERN3.0 bootcamp teaches this stack end-to-end with two portfolio projects and deployment.
Read guide - Week 1
Node.js & Express API Development for MERN
The backend of MERN runs on Node.js with Express. MERN3.0 Week 1 covers how websites work, HTTP methods, status codes, npm, Express setup, GET APIs, and the request/response cycle — before any database work.
Read guide - Week 2–3
MongoDB & Mongoose for MERN Developers
MongoDB stores JSON-like documents; Mongoose adds schemas and validation in Node.js. MERN3.0 Week 2 covers Atlas connection, models, create operations, and validation. Week 3 adds file uploads with Multer and full blog CRUD APIs.
Read guide - Week 4–5
React Fundamentals for Full-Stack Developers in Nepal
React powers the frontend in MERN. MERN3.0 Week 4 introduces why React beats plain HTML for SPAs, Vite setup, JSX transpilation, React Router, components, and props. Week 5 adds hooks and API integration.
Read guide - Week 5–6
React Hooks — useState & useEffect in MERN Projects
Hooks manage state and side effects in functional React components. MERN3.0 covers useState, useEffect types, Tailwind styling, CORS/CSRF/SOP concepts, and full blog UI integrated with your Express APIs.
Read guide - Week 6–7
TypeScript & OOP for MERN Stack Developers
Before the e-commerce project, MERN3.0 covers TypeScript basics, OOP fundamentals (inheritance, polymorphism, encapsulation), and WebSockets for realtime features — used later for live order status updates.
Read guide - Week 8–9
JWT Authentication in MERN Stack Apps
Secure apps need authentication. MERN3.0 Project 2 uses PostgreSQL with register/login, bcrypt hashing, cookies, JWT generation, forgot-password email, OTP verification, and role-based middleware.
Read guide - Week 13
Redux Toolkit for React State Management
Large React apps need centralized state. MERN3.0 Week 13 teaches Redux Toolkit — slices, reducers, actions, useDispatch, useSelector, async thunks, and API calls inside slices — then wires login and cart flows.
Read guide - Week 8–16
Full-Stack E-commerce Project with MERN
MERN3.0’s capstone is a full e-commerce platform: PostgreSQL backend, product/category APIs, cart, orders, admin dashboard, payments, WebSockets, and online hosting — a portfolio piece you can show employers in Nepal.
Read guide - Week 12
Khalti Payment Integration in MERN Apps
Nepal-specific payment skills matter for local products. MERN3.0 Week 12 covers Khalti payment integration in the order flow — a practical differentiator on your resume for Nepali startups and clients.
Read guide - Week 6, 16–17
Deploy MERN Projects & Docker Basics
Building locally is not enough — MERN3.0 teaches hosting MERN projects online multiple times and finishes with Docker & dockerizing the full MERN stack so you can ship and share portfolio URLs with recruiters.
