Advanced tools
Package description
The react-textarea-autosize package is a React component that automatically adjusts the height of a textarea to fit the content. It is useful for creating text input areas in web applications where the amount of text is dynamic and can grow or shrink.
Auto-resizing textarea
This feature allows the textarea to automatically resize between a minimum and maximum number of rows based on the content.
<TextareaAutosize minRows={3} maxRows={6} />
Minimum and maximum height
You can set a minimum and maximum height for the textarea, which will be respected during auto-resizing.
<TextareaAutosize style={{ minHeight: '100px', maxHeight: '300px' }} />
Controlled component
The component can be used as a controlled component, with its value being managed by the state of the enclosing component.
<TextareaAutosize value={this.state.text} onChange={this.handleChange} />
Uncontrolled component
The component can also be used as an uncontrolled component, where it maintains its own state.
<TextareaAutosize defaultValue='Initial content' />
Ref forwarding
React refs can be forwarded to the underlying textarea element, allowing for direct DOM access if needed.
const ref = React.createRef();
<TextareaAutosize ref={ref} />
This is a standalone script that can be applied to any textarea element to make it automatically adjust its height. It is not specifically designed for React and requires manual integration.
A similar React component that also resizes textareas to fit the content. It is an alternative to react-textarea-autosize with a slightly different API and feature set.
This package provides a text field component that automatically adjusts its size. It is similar to react-textarea-autosize but is designed for single-line input fields rather than multi-line textareas.
Readme
Drop-in replacement for the textarea component which automatically resizes textarea as content changes. A native React version of the popular jQuery Autosize! Weighs 1.65KB (minified & gzipped).

import Textarea from 'react-textarea-autosize';
// If you use CommonJS syntax:
// var Textarea = require('react-textarea-autosize').default;

<Textarea />
</div>,
document.getElementById('element')
);
npm install react-textarea-autosize

prop | type | description |
---|---|---|
inputRef | func | Function invoked with DOM node as argument. Default: () => {} |
maxRows | number | Maximum number of rows upto which the textarea can grow |
minRows | number | Minimum number of rows to show for textarea |
onHeightChange | func | Function invoked on textarea height change, with height as first argument and React component instance (this ) as second. Default: () => {} |
useCacheForDOMMeasurements | boolean | Use object cache when computing height of textarea. Default: false |
Apart from these, the component accepts all props that are accepted by <textarea/>
, like style
, onChange
, value
, etc.
Get a ref to inner textarea:
<Textarea inputRef={tag => (this.textarea = tag)} />
And then call a focus on that ref:
this.textarea.focus();
To autofocus:
<Textarea autoFocus />
(all HTML attributes are passed to inner textarea)
Because jest provides polyfills for DOM
objects by requiring jsdom and
react-test-renderer doesn't
provide refs for rendered components out of the box (calling ref callbacks with
null
), you need to supply a mocked ref in your tests in you need it for your tests.
You can do it like this (more can be read
here):
const tree = renderer
.create(<Textarea />, {
createNodeMock: () => document.createElement('textarea')
})
.toJSON();
To release patch, minor or major version:
% npm run release:patch
% npm run release:minor
% npm run release:major
This will run eslint, compile sources from src/
to dist/
, bump a version in
package.json
and then create a new git commit with tag. If tests or linter
fails — commit won't be created. If tasks succeed it publishes to npm and pushes
a tag to github.
