Generate React PropTypes from JSON objects or TypeScript interfaces. Perfect for adding runtime type checking to your components.

Input Format:

JSON Object

Make all props required (.isRequired)

Generated PropTypes

import PropTypes from 'prop-types';

const ComponentName = (props) => {
  // Component implementation
};

ComponentName.propTypes = {
name: PropTypes.string,
age: PropTypes.number,
email: PropTypes.string,
isActive: PropTypes.bool,
hobbies: PropTypes.arrayOf(string),
address: PropTypes.shape({
  street: PropTypes.string,
  city: PropTypes.string
}),
onClick: PropTypes.func
};

export default ComponentName;

PropTypes Mapping:

Basic Types:

string → PropTypes.string
number → PropTypes.number
boolean → PropTypes.bool
function → PropTypes.func

Complex Types:

array → PropTypes.array
object → PropTypes.shape()
string[] → PropTypes.arrayOf()

💡 Tip: PropTypes provide runtime type checking in development mode. For production apps, consider using TypeScript for compile-time type safety.
