VS Code Extensions That Actually Make Me More Productive

My curated list of VS Code extensions that earn their place. No fluff, just tools that improve my daily workflow.

5 min read Tools

I’ve tried hundreds of VS Code extensions. Most got uninstalled after a day. These are the ones that stuck because they genuinely make me faster and happier.

The Essential Ones

1. Prettier - Code Formatter

Why: Never think about formatting again.

Settings I use:

{
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "editor.formatOnSave": true,
  "prettier.singleQuote": true,
  "prettier.trailingComma": "es5"
}

Format on save = zero effort, perfect consistency.

2. ESLint

Why: Catch errors before they become bugs.

Works with Prettier. Configure once, forget about it.

{
  "eslint.autoFixOnSave": true,
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact"
  ]
}

3. GitLens

Why: Git superpowers built-in.

Features I use:

  • Blame annotations (who wrote this line?)
  • File history viewer
  • Compare branches
  • Rich commit search

The blame lens in particular saves me daily.

Language-Specific

4. ES7+ React/Redux/React-Native snippets

Why: Type less boilerplate.

rafce → React Arrow Function Component Export
useS → useState hook
useE → useEffect hook

Massive time saver for React work.

5. TypeScript Error Translator

Why: Makes TS errors actually readable.

Turns this:

Type 'string | undefined' is not assignable to type 'string'.
  Type 'undefined' is not assignable to type 'string'.

Into plain English explanations. Life-changing for beginners.

6. Tailwind CSS IntelliSense

Why: Autocomplete for Tailwind classes.

If you use Tailwind, this is non-negotiable. Autocomplete, linting, and hover previews.

Quality of Life

7. Auto Rename Tag

Why: Change opening tag, closing tag updates automatically.

<div>...</div>
<!-- Change div to section -->
<section>...</section>  <!-- Updates automatically! -->

Small thing, huge time saver.

8. Bracket Pair Colorizer (Built-in now!)

Why: Match brackets visually.

Actually built into VS Code now:

{
  "editor.bracketPairColorization.enabled": true,
  "editor.guides.bracketPairs": "active"
}

Makes nested code readable.

9. Better Comments

Why: Highlight different comment types.

// TODO: Fix this bug
// ! IMPORTANT: Security issue
// ? Should this be async?
// * Key feature here

Color-coded comments are easier to scan.

10. Error Lens

Why: See errors inline.

Instead of hovering over red squiggles, see the error message right in your code:

const x: number = "string";  // ← Type 'string' not assignable to 'number'

Controversial extension (some find it noisy), but I love it.

Navigation & Search

11. Path Intellisense

Why: Autocomplete file paths.

import './components/Button' // Autocompletes as you type

Especially useful for deep folder structures.

12. Advanced-new-file

Why: Create files fast.

Cmd+N → Type path → File created with directories

components/Button/Button.tsx  // Creates directories if needed

13. Bookmarks

Why: Mark important lines.

Toggle bookmarks with Cmd+Alt+K, jump between them with Cmd+Alt+L.

Great for navigating large files.

Testing & Debugging

14. Jest Runner

Why: Run tests directly in editor.

Click gutter icon to run a single test. See results inline. No terminal switching.

test('adds numbers', () => { // ← Click to run
  expect(add(1, 2)).toBe(3);
});

15. Thunder Client

Why: Postman alternative inside VS Code.

Test APIs without leaving your editor. Lighter than Postman, perfect for quick tests.

Appearance

16. Material Icon Theme

Why: Beautiful file icons.

Makes the file tree actually pleasant to look at. Different icons for .tsx, .test.ts, etc.

17. GitHub Theme (or your favorite)

Why: Easy on the eyes.

My current theme. Changes with the seasons (literally, I switch themes).

Other favorites:

  • Dracula Official
  • Night Owl
  • Nord
  • Catppuccin

Productivity Hacks

18. Paste JSON as Code

Why: Generate types from JSON.

Copy JSON, run command, get TypeScript interfaces. Magic.

{ "name": "Kevin", "age": 30 }

Becomes:

interface Root {
  name: string;
  age: number;
}

19. TODO Highlight

Why: Never lose track of TODOs.

Highlights TODO, FIXME, HACK in your code. Can list all TODOs in a sidebar.

20. Import Cost

Why: See bundle impact of imports.

import _ from 'lodash';  // 72.5kb (gzipped: 24.7kb)
import debounce from 'lodash/debounce';  // 2.3kb (gzipped: 1.1kb)

Helps me make better import decisions.

Remote Development

21. Remote - SSH

Why: Edit files on remote servers.

Connect to any server via SSH, edit files like they’re local. Full VS Code experience.

22. Dev Containers

Why: Develop inside Docker containers.

Full development environment in a container. Everyone on the team has identical setup.

The Settings I Actually Changed

{
  // Editor
  "editor.fontSize": 14,
  "editor.lineHeight": 1.6,
  "editor.fontFamily": "JetBrains Mono, Menlo, Monaco, monospace",
  "editor.fontLigatures": true,
  "editor.tabSize": 2,
  "editor.minimap.enabled": false,
  "editor.renderWhitespace": "boundary",
  
  // Files
  "files.autoSave": "onFocusChange",
  "files.trimTrailingWhitespace": true,
  "files.insertFinalNewline": true,
  
  // Terminal
  "terminal.integrated.fontSize": 13,
  "terminal.integrated.fontFamily": "JetBrains Mono",
  
  // Workbench
  "workbench.startupEditor": "none",
  "workbench.editor.enablePreview": false,
  
  // Git
  "git.autofetch": true,
  "git.confirmSync": false,
  
  // Emmet
  "emmet.includeLanguages": {
    "javascript": "javascriptreact"
  }
}

Extensions I Uninstalled

Auto Import - Too aggressive, broken imports Code Spell Checker - Too many false positives Live Share - Rarely used, resource heavy Settings Sync - Now built-in

Keyboard Shortcuts I Actually Use

{
  // My custom shortcuts
  "key": "cmd+shift+e",
  "command": "workbench.view.explorer"  // Toggle file explorer
},
{
  "key": "cmd+shift+f",
  "command": "workbench.action.findInFiles"  // Search in files
},
{
  "key": "cmd+shift+d",
  "command": "editor.action.duplicateLine"  // Duplicate line
}

Performance Tips

Too many extensions = slow VS Code.

Check what’s slow:

  1. Cmd+Shift+P → “Developer: Show Running Extensions”
  2. Sort by activation time
  3. Uninstall slowest ones you don’t use

My rule: If I haven’t used an extension in a month, it’s gone.

Theme-Based Workflow

I use different themes for different modes:

  • Day: GitHub Light
  • Night: GitHub Dark
  • Focus: Night Owl (minimal distractions)

Switch with Cmd+K Cmd+T

The Setup Process

New machine? Here’s my checklist:

  1. Install VS Code
  2. Sign in to sync settings
  3. Extensions auto-install
  4. Configure terminal (oh-my-zsh)
  5. Set up Git config
  6. Ready in 10 minutes

Extension Packs I Avoid

“React Extension Pack” with 20 extensions? No thanks.

I prefer installing only what I need. Keeps VS Code fast.

What I Use Outside VS Code

  • Warp - Terminal
  • Raycast - Launcher
  • Rectangle - Window management
  • Obsidian - Notes

VS Code is for coding. Other tools for other tasks.

Conclusion

Extensions should enhance your workflow, not complicate it. Start minimal, add as you find pain points.

My core setup:

  • Prettier + ESLint (code quality)
  • GitLens (git visibility)
  • Language-specific intellisense
  • A theme I like looking at

Everything else is optional. Find what works for you.

What extensions do you use? Always curious about hidden gems!

Happy coding! 🚀
