Top 6 Must‑Have VS Code Extensions for 2024 Developers

Visual Studio Code Overview

Visual Studio Code (VS Code) is a free, open‑source, cross‑platform code editor released by Microsoft in 2015. It runs on Windows, macOS and Linux and provides a built‑in extension marketplace that lets developers add language support, formatting tools, version‑control integration, themes, and many other capabilities.

Essential Extensions for 2024

1. Live Server

Live Server creates a local development server that automatically reloads the browser whenever HTML, CSS, or JavaScript files change. After installing the extension from the marketplace, you can start the server with the command Live Server: Open with Live Server (available via the Command Palette Ctrl+Shift+P). The server runs on http://127.0.0.1:5500 by default and supports custom ports, proxy settings, and HTTPS configuration.

4. Code Spell Checker

Code Spell Checker scans source files for English spelling errors in identifiers, comments, strings, and documentation. It provides suggestions and can be configured through the settings.json file to:

Ignore specific words or patterns (e.g., technical acronyms).

Set the language dictionary (default is US English).

Enable/disable checking for particular file types.

5. Beautify

Beautify formats JavaScript, JSON, CSS, Sass, and HTML according to configurable style rules. After installation, you can format a file with Shift+Alt+F or by selecting Format Document from the context menu. Custom settings (e.g., indentation size, line wrap) are stored in a .jsbeautifyrc file at the workspace root.

Note: The extension is no longer actively maintained, so compatibility with newer language features may be limited.

6. Better Comments

Better Comments helps organize code annotations by assigning colors to specific tags. Typical tags include: // TODO: – highlighted in blue. // ! – highlighted in red for warnings. // ? – highlighted in orange for questions. // * – highlighted in green for highlights.

The extension works out‑of‑the‑box; you can customize tag colors and add new tags via the better-comments.tags setting.
