10 VS Code Extensions That Actually Make You a Better Developer

Most "best extensions" lists are just people listing the same 20 popular extensions everyone already knows about. This isn't that.

These are the 10 I can't work without — and more importantly, why each one earns its place.

1. Error Lens

What it does: Displays error and warning messages inline, right next to the problematic code.

Without Error Lens, you have to hover over red squiggles or check the Problems panel. With it, errors are visible at a glance without breaking your focus.

const user = getUser()
             ~~~~~~~~~ Object is possibly 'undefined'  ← shown inline

Install: usernamehw.errorlens

2. Pretty TypeScript Errors

What it does: Makes TypeScript's notoriously verbose errors readable.

TypeScript errors can span 40 lines and be nearly unreadable. Pretty TypeScript Errors collapses and formats them into something human-readable.

[!TIP] Pair this with Error Lens — you get inline errors that are also readable. Game changer for TypeScript-heavy codebases.

Install: yoavbls.pretty-ts-errors

3. GitLens

What it does: Supercharges VS Code's built-in Git support.

The killer feature: inline blame annotations. Every line shows who wrote it and when, without leaving the editor. Also adds a full commit history timeline, file annotations, and branch comparisons.

Install: eamodio.gitlens

4. GitHub Copilot

What it does: AI pair programming built into the editor.

Yes, everyone knows Copilot. But in 2026 the chat-based interface for explaining code, generating tests, and refactoring whole functions is genuinely useful. The inline suggestions remain hit-or-miss for complex logic, but for boilerplate and repetitive patterns it's excellent.

Install: GitHub.copilot

5. REST Client

What it does: HTTP requests directly in .http files — no Postman or Insomnia needed.

### Get user profile
GET https://api.example.com/users/1
Authorization: Bearer {{token}}

### Create post
POST https://api.example.com/posts
Content-Type: application/json

{
    "title": "Hello World",
    "body": "My first post"
}

Click "Send Request" and the response opens in a side panel. Check these .http files into source control alongside your code.

Install: humao.rest-client

6. Thunder Client

What it does: Lightweight Postman alternative, fully inside VS Code.

If you prefer a GUI over .http files, Thunder Client is the answer. Minimal, fast, and stores collections as JSON that you can commit to git.

Install: rangav.vscode-thunder-client

7. Turbo Console Log

What it does: ctrl+alt+L to instantly insert a console.log for the selected variable.

It generates a log message with the variable name, file name, and line number automatically:

console.log("user.js ~ line 47 ~ user:", user);

Sounds small. Saves enormous time during debugging sessions.

Install: ChakrounAnas.turbo-console-log

8. Auto Rename Tag

What it does: Automatically renames the paired HTML/JSX closing tag when you rename the opening tag.

Every JSX developer needs this. Renaming <div> to <section> without manually updating the closing tag is friction that adds up.

Install: formulahendry.auto-rename-tag

9. Path Intellisense

What it does: Autocompletes file paths in import statements and src attributes.

import { Button } from '../../../  // → autocomplete shows your file tree

Works with aliases (@/components/...) when configured with pathMappings.

Install: christian-kohler.path-intellisense

10. Todo Tree

What it does: Aggregates all TODO, FIXME, HACK, and NOTE comments across your codebase into a sidebar tree.

// TODO: Replace this with a proper caching layer
// FIXME: This breaks when the array is empty
// HACK: Temp workaround until API v2 ships

All of these show up in a browsable tree, searchable, filterable by type. Essential for keeping tech debt visible.

Install: Gruntfuggly.todo-tree

My Settings for a Clean Setup

{
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "esbenp.prettier-vscode",
    "errorLens.enabledDiagnosticLevels": ["error", "warning"],
    "gitlens.blame.format": "${author|10} ${date|14}",
    "todoTree.highlights.enabled": true
}

What I Deliberately Left Out

• Prettier — install it as a project dependency, not just an extension
• ESLint — same
• Bracket Pair Colorizer — VS Code has this built in now (editor.bracketPairColorization.enabled)
• Live Server — use Vite's dev server instead

The best extension list is a short one. Every extension you add is a startup time cost and a potential conflict surface.
