Visual Studio Code is a popular code editor develop by Microsoft. It has a wide range of features, that make it an excellent tool for web development. Including syntax highlighting, code completion, and debugging capabilities. In addition to these built-in features, Visual Studio Code also has a vast ecosystem of extensions. That can enhance its functionality and help developers work more efficiently.
One of the key benefits, of Visual Studio Code extensions. Is that they allow developers to tailor the code editor to their specific needs and preferences. Whether you are a front-end developer working with HTML, CSS, and JavaScript. Or a back-end developer using languages, such as Python or PHP. There is likely an extension that can help you work more effectively.
In this article, we will highlight the top 5 must-have Visual Studio Code extensions for web developers. These extensions have been select base on their popularity, usefulness, and overall value for web development tasks. We will cover the features, and capabilities of each extension. As well as provide examples of how they can be use in real-world web development scenarios.
Prettier
Extension #1: Prettier
Prettier, is a popular code formatter for Visual Studio Code. That can help developers improve the readability and consistency of their code.

- Debugging web applications: Debugger for Chrome, can be use to debug web applications. Built with technologies such as React, Angular, and Vue.js.
Debugger for Chrome is similar to other debugging tools such as the Firefox Debugger and the Edge Debugger. However, it is specifically design for debugging web applications in the Chrome browser. And includes features such as variable inspection and a console that are not available in other debugging tools.
Live Server
Extension #3: Live Server
Live Server, is a Visual Studio Code extension. That allows developers to quickly spin up a local development server to test their web applications. It supports live reloading, which means that any changes made to the code. Will be automatically reflect in the browser without the need to manually refresh the page. This can help developers save time and work more efficiently.
Features of Live Server include:
- Quick setup: Live Server, can be easily set up with a single click. Without the need to install additional software or configure server settings.
