React - set focus on input after rendering

3 points
Created by:

In this article we would like to show you how in React set focus on input element immediately after component rendering.

In below example we use two React hooks:

  • useRef which stores refference to an input element,
  • useEffect in which .focus() method is called to get focus on the input element when App component is ready.

Runnable example:

// ONLINE-RUNNER:browser;

// Note: Uncomment import lines during working with JSX Compiler.
// import React from 'react';
// import ReactDOM from 'react-dom';

const App = () => {
    const inputRef = React.useRef();
    React.useEffect(() => {
        if (inputRef.current) {
    }, []);
    return (
          <label>Search: </label>
          <input ref={inputRef} />

const root = document.querySelector('#root');
ReactDOM.render(<App />, root );
