Frontend developers often live in VS Code—and for good reason. Since 2015, it’s become the go-to editor: fast, free, cross-platform, and dependable.
But what really makes VS Code shine isn’t just the core editor—it’s the extensions. The right ones transform it from a simple editor into a powerhouse for frontend development—automating tasks, catching bugs early, and streamlining your workflow.
Whether you’re building a new setup or refining an existing one, here are 10 essential VS Code extensions for frontend developers in 2025.
1. Prettier - Code formatter
Formats your code automatically on save. Works with HTML, CSS, JavaScript, Markdown, GraphQL, and more.
Why Frontend Devs Need It
No more formatting debates. Prettier enforces consistent styling across your codebase, which means cleaner git diffs and code reviews focused on logic, not whitespace.
Pro-Tip
Enable "Format On Save" in settings and drop a .prettierrc config file in your project root. Your whole team stays in sync without thinking about it.
2. ESLint
Analyzes your JavaScript in real-time, flagging bugs and enforcing code quality standards.
Why Frontend Devs Need It
ESLint catches the gotchas unused variables, missing dependencies in hooks, accessibility issues before they become runtime errors. Think of it as pair programming with a detail-obsessed teammate.
Pro-Tip
Pair it with Prettier using eslint-config-prettier to prevent rule conflicts. Enable auto-fix on save to let ESLint clean up your code as you work.
3. Live Server
Spins up a local development server with automatic browser refresh when file changes are saved.
Why Frontend Devs Need It
Hit save, see changes instantly. No manual refreshing, no context switching. Perfect for dialing in CSS animations or testing responsive breakpoints.
Pro-Tip
Point it at your build output folder (/dist or /build) if you're running a bundler. You can also customize the port and default browser in settings.
4. Path Intellisense
Automatically suggests file and folder names as you type paths.
Why Frontend Devs Need It
Stop guessing file paths. Path Intellisense suggests files as you type, eliminating "module not found" errors and speeding up navigation in deep folder structures.
Pro-Tip
If you use path aliases (@/components, ~/utils), configure them in settings so autocomplete works seamlessly with your custom imports.
5. GitLens
Supercharges Git with inline blame annotations, commit history, and code authorship details.
Why Frontend Devs Need It
Ever wonder "who wrote this and why?" GitLens answers that without leaving your editor. Essential for tracking down bugs, understanding legacy code, or collaborating effectively.
Pro-Tip
The inline blame can get noisy disable it and rely on hover tooltips instead. Use the file history view (GitLens: Open File History) to visualize changes over time.
6. Auto Rename Tag
Updates the closing tag automatically when you modify an opening tag.
Why Frontend Devs Need It
Change <div> to <section>, and the closing tag updates instantly. Sounds minor, but it prevents mismatched tags that break layouts especially in deeply nested JSX.
Pro-Tip
Make sure it's activated for JSX and TSX files by checking the activationOnLanguage setting.
7. ES7+ React/Redux/React-Native snippets
Provides smart snippets that can be quickly inserted into your code using short prefixes.
Why Frontend Devs Need It
Stop retyping boilerplate. Type rafce → get a full React component. Type useState → get a complete hook setup. It's faster than copy-pasting and more consistent.
Pro-Tip
Memorize the big ones: rafce (arrow function component), imr (import React), clg (console.log). You can also create custom snippets for patterns your team uses repeatedly.
8. vscode-icons
Replaces default file icons with colorful, file-type-specific icons.
Why Frontend Devs Need It
Your brain processes icons faster than text. Distinct visuals for .js, .jsx, .scss, .json, and config files make scanning large projects effortless.
Pro-Tip
Activate it via File → Preferences → File Icon Theme. Customize icon saturation and size to match your aesthetic preferences.
There's also the Material Icon Theme
9. Import Cost
Displays the size of imported packages directly within your editor.
Why Frontend Devs Need It
Performance starts with awareness. Import Cost displays how much each library adds to your bundle, helping you make smarter decisions before shipping bloated code.
Pro-Tip
When you see a surprisingly large import, investigate tree-shaking or lighter alternatives. Importing specific functions (lodash/debounce) instead of entire libraries can slash bundle size.
10. CSS Peek
Lets you peek at CSS definitions by hovering over class names in your markup.
Why Frontend Devs Need It
Stop jumping between files. Hover over a className → see the styles. Click to jump to the definition. It's a game-changer for debugging styles and refactoring CSS.
Pro-Tip
Use Cmd/Ctrl+Click on a class name to jump straight to its definition, or Cmd/Ctrl+Shift+F12 to peek without losing your place. Works with CSS, SCSS, LESS, and CSS Modules.
Wrapping Up
These extensions turn VS Code into an optimized tool for frontend development. They take care of tedious tasks such as formatting, linting, and path autocompletion, so you can focus on creating great UIs. The best part is that these extensions work together seamlessly. Prettier combined with ESLint helps maintain clean code, Live Server provides instant feedback, and GitLens offers useful context. Together, they create a workflow that feels effortless.
