Visual Studio Code extensions for Javascript developers

Recommended Visual studio code extensions for Javascript developers

In this article, we’ll be looking at awesome vscode extensions for Javascript developers.

Vscode is a free open-source text editing tool by Microsoft with support for developing applications using different programming languages. It has built-in Git functionality.

Install extensions to add new languages, themes, and debuggers, and connect to additional services. Extensions run in separate processes, ensuring they won’t slow down your editor.

It has a desktop app for Windows, Linux and macOS. Find out more about Vscode

Vscode is one of the best editors a developer should’ve.

The following are a few amongst many extensions out there to smoothen your development experience in building Javascript apps.

ES lint

Is a linting extension tool that automatically checks and analyzes codes for syntax, semantics, bugs, programmatic and stylistic errors and raises a flag. It ensures the codes are following the javascript standard guidelines. This is useful as it helps to inform and/or fix errors that will occur. This extension can be customized.

The extension uses the ESLint library installed in the opened workspace folder. If the folder doesn’t provide one the extension looks for a global install version. If you haven’t installed ESLint either locally or globally do so by running npm install eslint in the workspace folder for a local install or npm install -g eslint for a global install.

On new folders you might also need to create a .eslintrc configuration file. You can do this by either using the VS Code command Create ESLint configuration or by running the eslint command in a terminal. If you have installed ESLint globally (see above) then run eslint — init in a terminal. If you have installed ESLint locally then run .\node_modules.bin\eslint — init under Windows and ./node_modules/.bin/eslint — init under Linux and Mac.


Quokka.js is a developer productivity tool for rapid JavaScript / TypeScript prototyping. Runtime values are updated and displayed in your IDE next to your code, as you type.

Prettier — Code formatter

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.


Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file’s path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.
