React Formatter

Q: What is JSX and why does it need formatting?

JSX is a syntax extension for JavaScript that lets you write HTML-like code inside your JavaScript files. Because it mixes two syntaxes, it can become messy. A formatter applies consistent rules for indentation and line breaks to keep it clean and readable.

Q: What is a code formatter?

A code formatter automatically rewrites source code to conform to a set of style rules without changing its functionality. It helps teams maintain a consistent coding style, making code easier to read and review.

Q: Will this tool fix my broken React code?

No, this is a formatter, not a debugger. It will not fix logic errors. However, it can help you find syntax errors, because the formatter will fail if the code is not syntactically correct.

Q: What is 'Print Width'?

'Print Width' specifies the maximum number of characters allowed on a single line. The formatter will try to break long lines of code that exceed this width into multiple, more readable lines.

About the React Formatter

Our React Formatter is a tool we built to help developers write clean and consistent code. It takes your messy or unformatted React and JSX code and instantly makes it readable and organized. So, this helps you and your team maintain a high-quality codebase that is easy to understand and work on.

Working with JSX can be tricky because it mixes HTML-like syntax inside JavaScript. This tool, powered by the industry-standard Prettier engine, understands that syntax and formats it perfectly every time. You can just paste in your code, adjust a few settings like indentation and quote style, and get clean code back. It's a simple way to keep your components looking professional.

How to Use the Tool

Paste your React or JSX code into the "Input JSX" editor on the left.
Use the "Formatting Options" to customize the output, like changing the indentation size or quote style.
The beautifully formatted code will appear instantly in the "Formatted JSX" editor on the right.
If there is a syntax error in your code, the tool will let you know so you can fix it.
Use the buttons to copy the clean code to your clipboard or download it as a `.jsx` file.

Frequently Asked Questions

What is JSX and why does it need formatting?

JSX is a syntax extension for JavaScript, which is mainly used with React. It lets you write HTML-like code inside your JavaScript files. Because it mixes two different syntaxes, it can quickly become messy and hard to read. A formatter helps by applying consistent rules for indentation and line breaks, making the code clean and easy to follow.

What is a code formatter?

A code formatter is a tool that automatically rewrites source code to conform to a set of style rules. It doesn't change what the code does, but it changes how it looks. Using a formatter helps teams maintain a consistent coding style, which makes the code easier to read and review. This tool uses Prettier, one of the most popular code formatters in the world.

Will this tool fix my broken React code?

No, this is a formatter, not a debugger or a linter. It will not fix logical errors in your code. However, if your code has a syntax error (like a missing bracket or a typo), the formatter will fail and show an error. This can be a very quick way to find out that something is wrong with your code's syntax.

What is "Print Width"?

"Print Width" is an option that specifies the maximum number of characters allowed on a single line. The formatter will try to break long lines of code that exceed this width into multiple, more readable lines. The standard value is usually 80 characters, which is a historical convention that still helps with readability.

Is the code I paste into this tool private?

Yes, your code is 100% private. This tool runs entirely in your web browser. All the formatting is done on your own computer, and none of your code is ever sent to our servers. We believe your code is your own, and we respect your privacy completely.
