Where Can I Learn Node.js and Express for Free in 2025?

If you're looking to break into backend development, two names will come up again and again: Node.js and Express.js. Together, they power thousands of web applications, APIs, and services. The good news? You don’t need to enroll in an expensive bootcamp to learn them.

In 2025, there are plenty of high-quality, free resources to learn Node.js and Express from scratch. Whether you're aiming to build your first API or pursue a career in backend development, this article will guide you to the best free platforms—and show how one self-taught developer used them to land a full-time job.

Why Learn Node.js and Express?

Node.js is a runtime that allows you to write JavaScript for server-side applications. It’s fast, scalable, and widely used.

Express.js is a lightweight framework built on top of Node.js that simplifies routing, middleware, and server-side logic. It’s perfect for building RESTful APIs, microservices, and full-stack applications.

Skills in Node.js and Express are highly in-demand for roles such as:

• Backend Developer
  
  

• Full-Stack Developer
  
  

• API Engineer
  
  

• DevOps and SRE roles
  
  

Real Use Case: From YouTube Course to Backend Developer

One developer with basic JavaScript knowledge decided to dive deeper into backend development. Rather than paying for a course, they followed The Net Ninja's Node.js & Express.js tutorials on YouTube.

Here’s how they structured their learning:

1. Completed “Node.js Crash Course” followed by “Express.js Tutorial Series”
   
   

2. Built several mini-projects like a blog API, note-taking app, and authentication module
   
   

3. Developed a complete restaurant management API that included:
   
   

• CRUD operations for menus, orders, and users
  
  

• Middleware for logging and validation
  
  

• RESTful structure with proper routing
  
  

• MongoDB integration
  
  

They deployed the API using Heroku and documented the entire project on GitHub. The finished portfolio helped them secure interviews, and eventually a full-time backend developer job offer.
