Learn Node.js From Basics to Production

Node.js is what turns JavaScript into a backend language — and MERN and MEAN stack roles are among the most advertised fresher jobs in India. This free course runs from the event loop and core modules through Express APIs, MongoDB, authentication, testing, performance and deployment.

Node.js Tutorial — Frequently Asked Questions

Is this Node.js tutorial free?+

Yes — every lesson is free with no sign-up. The course covers Node from the event loop and core modules through Express, MongoDB, authentication, testing and production deployment.

Do I need to know JavaScript before learning Node.js?+

Yes. You should be comfortable with functions, objects, array methods, promises and async/await. Node adds server-side APIs rather than new language syntax, so JavaScript gaps show up immediately.

Is Node.js single-threaded?+

Your JavaScript runs on a single thread, but Node offloads file, network and crypto work to a thread pool and to operating-system async APIs. That is how one process handles thousands of concurrent connections.

Node.js or Python for backend development?+

Node if you already know JavaScript and want full-stack or MERN roles, which are widely advertised in India. Python if you are heading towards data science, machine learning or Django-based companies. Both are strong backend choices.

How long does it take to learn Node.js?+

About two to three months of consistent daily practice to reach job-ready level. The roadmap lesson sets out a ten-week plan ending with a deployed API.

Do I need to learn Express, or is plain Node enough?+

Learn the http module first so you understand what a framework does, then learn Express — almost every Node job posting mentions it, and it removes a large amount of boilerplate around routing, body parsing and error handling.
