Ideal for developers looking to build back-end skills, this Node.js course shows you how to develop fast, scalable web apps with JavaScript. You’ll learn how Node.js handles requests, manages data, and connects to databases.
Developing Node.js Web Applications
Create scalable web applications with Node.js
Over two interactive days, our expert trainers will take you through core Node.js concepts like asynchronous processing, module management, REST APIs (Application Programming Interface) and security. Designed for developers with a JavaScript background, you’ll learn how to use Node.js to build web servers, manage data flow, and create secure applications.
Learning objectives
- Configure a Node.js environment
- Use modules and NPM (Node Package Manager)
- Write async code with callbacks and promises
- Stream and buffer data
- Handle files and errors
- Build RESTful APIs
- Route requests with Express
- Secure endpoints with JWT (JSON web token)
- Connect to SQL and MongoDB (open-source NoSQL database)
What you’ll learn
Use Node.js to build and secure network applications. Explore real-time data handling, learn to structure APIs using Express, and manage persistence through SQL or MongoDB. Once complete, you’ll have the confidence to build full-stack JavaScript apps from the ground up.
Introduction to Node.js
Discover how Node.js brings JavaScript to the server, enabling you to build fast, scalable network applications. You’ll gain a clear understanding of its event-driven architecture and non-blocking I/OD model, and how these features help manage high volumes of concurrent connections. This foundation will help you write efficient code and prepare you for more advanced techniques later in the course.
Mastering asynchronous programming
Learn how to write efficient, non-blocking code using asynchronous techniques that are central to Node.js development. You’ll discover how to manage the flow of execution with callbacks, promises, and the async/await syntax, making your code cleaner and easier to maintain. By the end of the course, you’ll understand how to build responsive applications that can handle multiple operations simultaneously without slowing down.
The Express.js framework
Discover how Express.js streamlines web application development by handling routing, middleware, and server-side logic with ease. You’ll learn how to structure applications using RESTful principles, define routes to manage requests and responses, and integrate features like file uploads. The course covers best practices for building scalable APIs, demonstrating how Express helps you keep your code clean and maintainable as your application grows.
Securing Node.js APIs
Protect your applications with industry-standard authentication techniques. This course teaches you how to securely store and manage user credentials using password hashing, and how to generate and validate JSON Web Tokens (JWT) to maintain session integrity. These practical skills are essential for developing secure, production-ready APIs that meet modern security expectations.

FAQs
Learn to create scalable, secure Node.js applications. This course teaches you how to use tools like Express and MongoDB, covering async patterns, APIs and modern security practices through hands-on exercises.
Do I need prior knowledge of JavaScript to join this course?
Yes, a solid understanding of JavaScript is essential. You should be confident with functions, objects and basic logic.
Don’t have any prior experience working with JavaScript? Don’t worry, our JavaScript Developer course is a great alternative course for beginners.
Will I build a working Node.js application during the course?
This course takes a hands-on approach to learning, making it easier to apply what you’ve learnt in your own projects or at work. By the end of the course, you’ll have built components of a functioning web application, including setting up a server, handling requests with Express, integrating a database, and applying authentication.
What’s the difference between using callbacks, promises and async/await?
Callbacks, promises and async/await are all techniques used in Node.js to handle asynchronous operations.
- Callbacks are functions passed into another function to run once an operation is complete. While effective, they can become difficult to manage as complexity grows
- Promises offer a more readable alternative. They represent a value that may be available in the future and let you chain actions and handle errors, making your code easier to follow
- Async/await builds on promises and brings asynchronous code closer to a synchronous style, using async functions and await expressions. This structure improves readability and helps you handle errors more cleanly using try/catch blocks
All three are covered in the course, so you can learn when and how to use them effectively in different development scenarios.
