React Autosize Textarea

A light replacement for built-in <textarea /> component which automatically adjusts its height to match the content.

NB: It does not require any polyfill

import ReactDOM from 'react-dom';
import TextareaAutosize from 'react-autosize-textarea';

ReactDOM.renderComponent(
  <TextareaAutosize {...textareaProps} onResize={(e) => {}} />,
  document.body
);

Install

npm install --save react-autosize-textarea

Usage

You can pass any prop you're allowed to use with the default React textarea (valueLink too).

You can also pass the optional callback onResize which will be triggered at any resize with the autosize:resized event object:

function onResize(event) {
  console.log(event.type); // -> "autosize:resized"
}

<TextareaAutosize onResize={onResize} />

Set min/max height

You can set minHeight and maxHeight through CSS or inline-style as usual:

<TextareaAutosize style={{ minHeight: 20, maxHeight: 80 }} /> // min-height: 20px; max-height: 80px;

NB: you may need to take into account borders and/or padding.

In addition to minHeight, you can force TextareaAutosize to have a minimum number of rows by passing the prop rows:

<TextareaAutosize rows={3} /> // minimun height is three rows
