npm version npm


Drop-in replacement for the textarea component which automatically resizes textarea as content changes. A native React version of the popular jQuery Autosize!

This module supports IE9 and above.

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


npm install react-textarea-autosize



How to test it with jest and react-test-renderer

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. You can do it like this (more can be read here):

const tree = renderer
  .create(<Textarea />, {
    createNodeMock: () => document.createElement("textarea")


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 lib/, es/ and 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.
