Master server-side JavaScript with Node.js through hands-on practice. Learn modules, file system operations, HTTP servers, npm, async patterns, and REST APIs. Build real backend applications with interactive exercises in your browser.
This free interactive Node.js basics course is designed for developers who already know JavaScript and want to move from the browser to the server. You will work through nine hands-on modules covering the core building blocks of back-end development: Node's module system (both CommonJS and ES Modules), file system operations, HTTP server creation, npm and package management, environment variables, and configuration patterns.
The course goes deeper than syntax. You will build a solid understanding of asynchronous JavaScript by working through callbacks, Promises, async/await, and the event loop in sequence, so each concept reinforces the last. The final two modules put it all together: you will construct a REST API with CRUD endpoints and middleware patterns, then learn how to handle errors and apply Node.js best practices in real projects. All exercises run directly in your browser, so there is no local setup required to get started.
By the time you finish, you will be equipped to build and structure back-end applications using Node.js from scratch. Every exercise runs in the browser, and completing the course and its final exam earns you a certificate of completion you can add to your LinkedIn profile or resume.

The course walks through nine modules: the Node.js runtime itself, the CommonJS and ES Module systems, file system operations, HTTP servers, npm and package management, environment variables and configuration, async patterns (callbacks, Promises, async/await, and the event loop), building a REST API, and error handling with best practices. Each topic builds on the previous one so you finish with a complete picture of back-end JavaScript.
Yes, the entire course is free and no account is required to start learning. If you complete all the modules and pass the final exam, you receive a certificate of completion at no cost.
The course is rated intermediate, so a working knowledge of JavaScript (variables, functions, arrays, and objects) is expected. You do not need any prior back-end or server-side experience, and no local installation is needed because all exercises run in the browser.
The exercises focus on core Node.js built-in modules such as fs and http, along with npm for package management. You will also work with JSON configuration, environment variables, and REST API design patterns. No external frameworks are required, keeping the focus on Node.js fundamentals.
Yes. Completing the course and passing the final exam earns you a certificate of completion that you can share on LinkedIn or include in your resume or portfolio.
