FAQ

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') }
).toJSON();

Development

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.
