FAQs
The two-day Developing Node.js Web Applications Node.js live virtual classroom course is designed for developers who already understand JavaScript and want to apply those skills beyond front-end development. It is particularly relevant if you need to contribute to back-end services, API development or full-stack application work using Node.js.
What experience should I have before attending?
You should have JavaScript fundamentals and a basic understanding of HTML and CSS before joining the course. Prior completion of JavaScript Developer training is recommended as a useful starting point, but the confirmed requirement is existing knowledge of JavaScript, HTML and CSS.
How practical is the course?
The course includes interactive live labs and practical exercises, so you can apply Node.js concepts as you learn them. This helps you move beyond theory and build confidence with the workflows used to create back-end services, work with data and develop APIs.
How will this course help me at work?
You’ll build practical skills for creating server-side JavaScript applications, managing data, defining routes, connecting to databases and applying API authentication. These capabilities can help you contribute more effectively to web application delivery and support teams working with connected digital services.
What will I learn about APIs?
You’ll learn how Node.js and Express are used to create web servers, configure routes, handle requests and responses, and build REST applications. This gives you a clearer understanding of how APIs connect application components, front-end interfaces and external systems.
Does the course cover databases?
Yes. The course covers connecting Node.js applications to SQL databases and MongoDB. It also includes schema management and transaction handling, helping you understand how back-end applications store, organise and manage data as part of wider application workflows.
Do we cover security topics during the course?
The course teaches you about password protection, JSON Web Tokens and authenticated endpoints. These topics help you understand how Node.js applications manage access to APIs and protect routes that should only be available to authorised users.
