20 Powerful VS Code Extensions for Front-End Developers

Visual Studio Code, Microsoft’s powerful code editor, has quickly become a favorite in the developer community. The editor’s versatility is significantly enhanced by a wide array of extensions available in the Visual Studio Code Marketplace. These extensions are particularly beneficial for web developers, offering tools and features that streamline various aspects of coding and development.

In this post, we delve into the world of VS Code extensions, specifically focusing on front-end development. After exploring numerous extensions, I’ve curated a list of those that stand out for their intuitiveness, ease of use, and convenience. While this list is informative, the marketplace is constantly evolving with new and improved extensions, so I encourage you to explore it further and discover the tools that best suit your development needs.

How to Install VS Code Extensions?

Installing an extension is pretty straightforward in Visual Studio Code, as you can do it within the code editor. In the VS Code Marketplace every extension has its own page, and you can find the command you can install the given extension with on top of this page.

The command always begins with the ext install term. To install an extension, just press CTRL+P inside VS Code to start the Quick Open panel, copy-paste this command into it, and finally restart the code editor to make the new extension work.

Useful VS Code Extensions for Developers

HTML Snippets

If you want to frequently write HTML in Visual Studio Code, the HTML Snippets extension can come as a handy tool, as it adds elaborate support for HTML. Although VS Code has basic support for HTML, such as syntax colouring, the HTML Snippets extension knows much more.

HTML Snippets

Probably the most useful feature of this extension is that when you begin to type the name of an HTML tag (without the starting angle bracket), HTML Snippets quickly displays a list of the available options with a short information about each.

HTML Snippets Anchor Tag

When you click on the element you need, HTML Snippets adds the full HTML5 tag with its most common properties. For instance, if you want to add a link (anchor tag) to your document, just type an a into VS Code, choose the right option in the popup box, and HTML Snippets will insert the necessary <a href=""></a> snippet into your editor without any hassle.

The author of this extension also pays attention to remove deprecated elements, so if you want to use an HTML tag that you can’t find in the popup list, it’s worth to check out whether it’s still valid or not.


Ever found logging messages a bit tedious? The turbo-console-log extension is here to help. It makes creating log messages a breeze. Just choose the variable you want to check and hit Control + Alt + L.

Turbo Console Log Demo

Voila! A detailed log message appears right after. It’s not just about adding messages; you can quickly comment, uncomment, or delete all logs in your document, making your coding smoother and more productive.


Meet Prettier, the code formatter that cares about consistency. It’s like having a strict editor for your code, ensuring everything looks uniform. As you save, Prettier takes over, parsing and reformatting your code to follow set rules.

It considers line length, wraps code neatly, and lets you choose which languages to format. Say goodbye to style inconsistencies in your code!

HTML CSS Class Completion

HTML CSS Class Completion can be a helpful extension if you need to use many CSS classes in your project. It frequently happens to us developers, that we are not completely sure in the exact name of a class, but it just sits at the back of our mind as passive knowledge.

This smart extension gives a solution for this problem, as it fetches the names of all CSS classes in the current workspace, and displays a list about them.

HTML CSS Class Completion

Let’s say, you want to create a site using Zurb Foundation, and you want to use the small grid. You don’t remember how the classes are exactly named, but you know they have semantic names.

With HTML CSS Class Completion you only need to start to type the word small, and the available options appear on your screen at once, so you can easily select the one you need.

HTML CSS Class Completion Example
Import Cost

Concerned about your code’s performance? The Import Cost extension is like a vigilant assistant, keeping an eye on performance as you code. It might not analyze your entire bundle, but it alerts you to heavy imports before they bog down your users.

Import Cost Extension Display

As you bring in a third-party library, Import Cost shows its size right next to your code, helping you maintain a lean, efficient project.

It can facilitate front-end development by allowing you to have a quick look at the result of your work in the browser while coding. You can open your HTML file in your default browser directly from VS Code by pressing the CTRL + F1 keyboard shortcut.

Note that View in Browser only supports HTML, so if you want to see your site you need to have the HTML file open. You can’t directly access the browser from a CSS or JavaScript file.

Debugger for Chrome

The extension has every feature a decent debugger needs, such as breakpoint setting, variable watching, stepping, a handy debug console, and many others (see the feature list of the first release).

This tool uses a color-coded system to indicate the level of harm these characters pose. It also marks lines with a Gremlins icon and provides detailed hints about these characters when you hover over them, helping you maintain clean and error-free code.


Visual Studio Code’s JSHint extension integrates the popular JSHint JavaScript linter right into the code editor, so you can be informed about your errors as soon as you commit them. By default, the JSHint extension uses the default options of the linter that you can customize with the help of a configuration file.


The usage of this extension is quite straightforward, as JSHint marks the errors with red, and the notifications with a green underline. If you want more information on the issues, just hover over the underlined parts, and JSHint will float a label with the description of the problem at once.
