Visual Studio Code dominates the web development editor market for good reason. The extension ecosystem turns a lightweight text editor into a full development environment. But with over 40,000 extensions available, finding the ones that actually improve your workflow takes time. These are the extensions we use daily.
Essential Extensions
ESLint
Integrates ESLint into VS Code for real-time JavaScript and TypeScript linting. Shows errors inline as you type, supports auto-fix on save, and works with custom configurations. If you write JavaScript, this is non-negotiable.
Prettier
Opinionated code formatter that supports JavaScript, TypeScript, CSS, HTML, JSON, Markdown, and more. Set it as your default formatter and enable format-on-save. Eliminates all code style discussions in team projects.
GitLens
Supercharges the built-in Git support with inline blame annotations, commit history per file, and visual diff comparisons. The file history and line history views are invaluable for understanding why code changed. The free version covers everything most developers need.
Live Server
Launches a local development server with hot reload for static HTML, CSS, and JavaScript files. One click to start, automatic browser refresh on save. Essential for front-end prototyping and testing form interactions without a build tool.
REST Client
Send HTTP requests directly from VS Code without switching to Postman or curl. Write requests in .http files with variables, authentication, and response handling. Great for API testing during development.
Code Quality
Error Lens
Displays diagnostic messages (errors, warnings, info) inline at the end of the line where they occur. No more hovering over squiggly underlines to read error messages. Makes problems immediately visible.
Code Spell Checker
Catches typos in code, comments, and strings. Supports camelCase and snake_case splitting, custom dictionaries, and multiple languages. Prevents embarrassing variable name typos from making it to production.
Productivity
Auto Rename Tag
Automatically renames the paired HTML/XML tag when you edit one. Edit the opening tag and the closing tag updates instantly. Saves time and prevents mismatched tags in templates.
Path Intellisense
Autocompletes file paths in import statements, HTML src attributes, and CSS url() values. Works with relative and absolute paths. Reduces typos in file references and speeds up imports.
