FAQ
How to focus
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)
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 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.
