react-pseudostyler

Allows a React component to be rendered with pseudo-class styles applied

Why does this component exist?

Have you ever wanted to take a visual snapshot of a component in a certain state, say, with a hover style applied? Looking for a way to apply styles defined by a pseudo-class using JavaScript, only to find out you can't?

We've got your back.

Install

npm install --save react-pseudostyler

Usage

Wrap your component in PseudoStyler.

Props:

• selector: the pseudo-class you'd like to applied, for example :active or :hover
• target: a function that allows you to target a specific html element. The function is passed a single argument with queries from dom-testing-library. The function should return the element you wish to apply pseudo-classes to.

import React, { Component } from 'react';
import PseudoStyler from 'react-pseudostyler';

class Example extends Component {
  render() {
    return (
      <PseudoStyler
        selector=":hover"
        target={({ getByText }) => getByText(/I have hover styles!/i)}
      >
        <MyCoolComponent>I have hover styles!</MyCoolComponent>
      </PseudoStyler>
    );
  }
}

The bulk of the logic in this component was pilfered from https://github.com/TSedlar/pseudo-styler, with a few small changes to provide easier usage from React.
