Format Code with Extensions in VSCode

In the world of coding, efficiency, and readability are paramount. Being able to format your code seamlessly can save you countless hours of debugging and make your codebase much more maintainable. Learn here how to Format Code with Extensions in VSCode.

Visual Studio Code (VSCode), one of the most popular code editors, offers built-in formatting options, but its true power lies in its extensibility through a wide range of extensions. In this article, we’ll explore the art of how to format code with extensions in VSCode, providing you with the tools to enhance your coding experience.

Why Code Formatting Matters

Before diving into the world of extensions, let’s understand why code formatting matters. Well-formatted code is easier to read and understand, both for yourself and for your collaborators.

It reduces the chances of introducing bugs and makes debugging a smoother process. Additionally, consistent formatting is crucial when working in a team, ensuring that everyone follows the same coding style. That’s why it’s important to learn how to Format Code with Extensions in VSCode.

Extensions vs. VSCode Built-In Formatter

When it comes to Format Code with Extensions in VSCode (Visual Studio Code), developers have a crucial decision to make: should they rely on the built-in formatter in VSCode or opt for a dedicated VS Code extension like Prettier? Both options offer code formatting capabilities, but they come with distinct features and considerations.

There are two ways to Format Code with Extensions in VSCode editor for beginners:

1. Using VSCode built-in code formatting shortcuts
2. Dedicated VS Code formatting extensions

Now, let’s talk about the above-mentioned two ways to format code in the VSCode editor in detail.

Basic Code Formatting Shortcuts

Efficiency is paramount for developers, and Visual Studio Code (VSCode) offers a plethora of keyboard shortcuts to streamline your coding workflow. When it comes to code formatting, these shortcuts can save you precious time and ensure your code adheres to your chosen style.

Here are some essential code formatting shortcuts in VSCode that every developer should know:

1. Format Document: Shift + Alt + F
   • This shortcut will format the entire document based on your configured formatting settings.
2. Format Selection: Ctrl + K followed by Ctrl + F
   • Highlight a portion of your code and use this shortcut to format only the selected text.
3. Toggle Word Wrap: Alt + Z
   • While not a code formatter per se, toggling word wrap can help make your code more readable when lines are too long.

Language-Specific Shortcuts

4. JavaScript/TypeScript Specific: Shift + Alt + F
   • When working with JavaScript or TypeScript, this shortcut formats your code according to the configured ESLint rules.
5. HTML Format Document: Shift + Alt + F
   • When editing HTML files, this shortcut formats the entire document, ensuring clean and well-structured markup.
6. JSON Format Document: Shift + Alt + F
   • When dealing with JSON files, this shortcut ensures your JSON objects are properly indented and formatted.

Custom Shortcuts

8. Create Your Own Shortcut: File > Preferences > Keyboard Shortcuts
   • VSCode allows you to create custom keyboard shortcuts for specific formatting needs or extensions. Define your preferred key combination in the user or workspace settings.
