The below code is an example of a React. You have to import React and set minLength={5} in <input/> to add minlength in react js.

App.js

import React, { useState } from 'react';

const App = () => {
  const [inputValue, setInputValue] = useState('');

  const handleChange = (event) => {
    setInputValue(event.target.value);
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    // Handle form submission
    console.log('Form submitted with value:', inputValue);
  };

  return (
    <form onSubmit={handleSubmit}>
      <label>
        Enter text (minimum 5 characters):
        <input
          type="text"
          value={inputValue}
          onChange={handleChange}
          minLength={5}
          required
        />
      </label>
      <button type="submit">Submit</button>
    </form>
  );
};

export default App;
