Demo & Examples

Live demo: jedwatson.github.io/react-input-autosize

To run the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.

Installation

The easiest way to use React-Input-Autosize is to install it from NPM and include it in your own React build process (using Browserify, rollup, webpack, etc).

You can also use the umd build by including dist/AutosizeInput.js in your page. If you use this, make sure you have already included a umd React build.

npm install react-input-autosize --save

Usage

React-Input-Autosize generates an input field, wrapped in a <div> tag so it can detect the size of its value. Otherwise it behaves very similarly to a standard React input.

import AutosizeInput from 'react-input-autosize';

<AutosizeInput
	name="form-field-name"
	value={inputValue}
	onChange={function(event) {
		// event.target.value contains the new value
	}}
/>

Gotchas

Custom font sizes

If your input uses custom font sizes, you will need to provide the custom size to AutosizeInput.

<AutosizeInput
	name="form-field-name"
	value={inputValue}
	style={{ fontSize: 36 }}
	onChange={function(event) {
		// event.target.value contains the new value
	}}
/>

Uncontrolled input

AutosizeInput is a controlled input and depends on the value prop to work as intended. It does not support being used as an uncontrolled input.
