Full-Stack Development with Modern Stacks is a project-based course designed for learners aiming to build complete web applications using popular front-end and back-end technologies. The course introduces three widely used stacks—MERN (MongoDB, Express.js, React, Node.js), MEAN (MongoDB, Express.js, Angular, Node.js), and Next.js (React-based server-side rendering). Learners begin by creating RESTful APIs and GraphQL endpoints with Express.js and integrating them with NoSQL databases like MongoDB. Back-end concepts include routing, middleware, authentication (JWT, OAuth2), role-based access control, and CRUD operations. On the front-end, students build responsive UIs using React or Angular, managing state with Redux or RxJS, and styling with Tailwind CSS or Bootstrap. The Next.js module focuses on server-side rendering, API routes, static site generation, and performance optimization. Learners also implement third-party integrations such as payment gateways (Stripe), email services (SendGrid), and cloud storage (Firebase, Cloudinary). DevOps concepts like containerization with Docker and deployment to platforms like Vercel, Netlify, Heroku, or AWS are covered. Security practices, error handling, and accessibility are emphasized throughout. By the end, learners will have built and deployed full-stack applications, demonstrating proficiency in both client and server technologies, and preparing them for real-world web development roles.
