What is JS Beautifier?

JS Beautifier is a utility that reformats and re-indents your JavaScript code. It helps take ugly, unorganized code and presents it in a readable format, making it easier for developers to collaborate and maintain their projects.

Usage Guide

Now that you have installed JS Beautifier, it’s time to learn how to use it!

Using JS Beautifier in a Web Browser

You can beautify your JavaScript in your browser simply by visiting beautifier.io. You will find an interface with options to customize your beautification process.

Using JS Beautifier via Command-Line

  • For beautification via the command line on Node.js, use:
  • js-beautify file.js
  • To beautify a JavaScript string as a library:
  • var beautify = require('js-beautify').js;

Options Configuration

JS Beautifier allows you to specify options to customize how your code is beautified. Below are some common options:

  • preserve_newlines: Preserve existing line breaks
  • space_in_empty_paren: Add a space inside empty parentheses

Understanding the Code via Analogy

Think of your code as a messy room filled with scattered papers and clothes. When you beautify your code, it’s like cleaning that room up; you organize the papers, fold the clothes, and remove unnecessary items. Each beautifying option, such as indent_size or preserve_newlines, is akin to the decisions you make while cleaning, ensuring everything has its rightful place and is aesthetically pleasing.

Troubleshooting Tips

If you encounter any issues, consider the following troubleshooting ideas:

  • Ensure that you have properly installed the dependencies.
  • Check that the file you are trying to beautify exists and is accessible.
  • Review your options to ensure they are written correctly according to the expected structure.
