How to Format TSX/TypeScript React Code - Step by Step Guide

Step 1

Input Your TSX/TypeScript React Code

Let's get your TSX code into the formatter! Whether you're working with TypeScript React components, building type-safe applications, or want to ensure consistent code style, you have several convenient options:

•
Paste directly: Copy your TypeScript React component or TSX code and paste it into the input editor
•
Upload a file: Click "Upload" to select a .tsx, .ts, or .txt file from your computer
•
Try the sample: Click "Sample" to load example TypeScript React component code and see how the formatter works

Example: Unformatted TSX Input

Here's what messy, unformatted TSX looks like:

interface Props{user:User}const UserCard:React.FC<Props>=({user})=>{return (<div className="card"><img src={user.avatar} alt={user.name}/><h2>{user.name}</h2><p>{user.email}</p></div>)}
Step 2

Automatic Formatting & Type Validation

The magic happens instantly! As soon as you input TSX, the formatter automatically:

•
Validates TypeScript syntax: Checks for TSX errors and type issues with helpful suggestions
•
Adds proper indentation: Makes typed components and TSX elements easy to read
•
Syntax highlighting: Color-codes TypeScript types, interfaces, and elements for better readability

Example: Beautifully Formatted Output

The same TSX, now properly formatted and readable with type annotations:

interface Props {
  user: User;
}

const UserCard: React.FC<Props> = ({user}) => {
  return (
    <div className="card">
      <img
        src={user.avatar}
        alt={user.name}
      />
      <h2>{user.name}</h2>
      <p>{user.email}</p>
    </div>
  )
}
Step 3

Export Your Formatted TSX

Get your perfectly formatted TSX code ready for use! Multiple export options make it easy to integrate into your TypeScript React workflow:

•
Copy to clipboard: One-click copying for quick pasting into your code editor or IDE
•
Download as file: Save as a .tsx file for later use or sharing with your team
•
Minify option: Click "Minify" to compress TSX for production builds (removes unnecessary whitespace)
•
Real-time validation: Green checkmark confirms your TSX is valid and ready to use in TypeScript React

Frequently Asked Questions

What is TSX and why do I need a formatter?

TSX is TypeScript's version of JSX, allowing you to write React components with full type safety. A formatter ensures consistent code style, proper indentation, and readability across your TypeScript React components, making code maintenance easier and team collaboration smoother while preserving type annotations.

Does this formatter preserve TypeScript type annotations?

Yes! The formatter preserves all TypeScript type annotations, interfaces, generics, and type assertions. It formats your TSX while maintaining complete type safety, ensuring your TypeScript React code remains fully typed and validated.

Can I format React Hooks with TypeScript?

Absolutely! The formatter fully supports typed React Hooks including useState, useEffect, useCallback, useMemo, and custom hooks with full TypeScript generic support. It properly formats all modern TypeScript React patterns and best practices.

Does the formatter validate TypeScript syntax errors?

Yes! The formatter validates TSX syntax and displays clear error messages if there are issues like unclosed tags, invalid TypeScript syntax, or type errors. This helps catch bugs early before compiling your TypeScript React app. Also check out this TSX Validator.

Can I minify TSX for production builds?

Yes! Click the "Minify" button to compress your TSX code by removing unnecessary whitespace and formatting while preserving TypeScript types. This is useful for reducing file size, though modern build tools like Vite or Webpack typically handle this automatically during compilation.

Is the TSX formatter completely free?

Yes, completely free with no limitations on file size, usage frequency, or features. No registration required, and you can format unlimited TSX/TypeScript React files with full syntax highlighting and type validation. Perfect for TypeScript React developers of all levels!
