Open Live Preview

Designed for Production Migration

Accurate, secure translation tailored for modern React ecosystems.

AST prop inference

Extracts TypeScript prop types and state generics automatically from usage patterns using Babel AST parser.

Type-safe output

No guess-work or hallucinations. Accurate TypeScript interfaces representing real component structures.

Zero lag processing

Instantly handles components with over 5,000 lines, custom React hooks, contexts, and imports.

Secure & private

Runs completely in-memory server-side under authenticated HTTPS. We never store your source code.

How Type Inference Works

Three steps from plain JavaScript to fully typed TypeScript.

Paste JSX component

Drop any React JSX component — functional, with hooks, context, or external packages. Both plain and arrow functions work.

AST analysis

Babel parses your code into an AST. Props, useState calls, refs, and callbacks are analyzed to infer exact TypeScript types.

Get typed TSX

Type annotations and interfaces are injected automatically. Copy the output or use it directly in your TypeScript project.

Before & After Examples

See how plain JSX patterns translate to strict TypeScript.

Prop DestructionMaps component arguments to interface definitions

Before (JSX)

function ActionButton({ title, onClick }) {
  return <button onClick={onClick}>{title}</button>;
}

After (TSX)

interface ActionButtonProps {
  title: string;
  onClick: () => void;
}

const ActionButton: FC<ActionButtonProps> = ({ title, onClick }) => {
  return <button onClick={onClick}>{title}</button>;
};

Hook TypesExtracts correct generic signatures based on default states

Before (JSX)

const [id, setId] = useState('');
const [items, setItems] = useState([]);

After (TSX)

const [id, setId] = useState<string>('');
const [items, setItems] = useState<any[]>([]);

Frequently Asked Questions

How does the JSX to TSX conversion work?▼

The converter parses your JavaScript JSX component into an Abstract Syntax Tree (AST) using Babel. It then analyzes React useState hooks, destructured props, and reference variables to infer correct TypeScript type definitions and injects prop interfaces before rendering the typed TSX output.

Is my code secure and private?▼

Absolutely. We do not store, log, or share your source code. The translation is processed entirely in-memory during the secure API call and immediately discarded.

Does the converter infer useState generics?▼

Yes. For example, if you have `useState(0)`, it infers `useState<number>(0)`. If you have object structures, it sets up basic type structures accordingly.

How are destructured props handled?▼

Destructured parameters like `function Button({ label, onClick })` are analyzed to construct a corresponding `ButtonProps` interface containing matching type annotations.
