A library of React components for ONS registers projects, using the external ONS pattern library.

import React from 'react';
import PropTypes from 'prop-types';
import Loader from 'halogen/PulseLoader';

class Button extends React.Component {
  componentDidMount() {
    // some logic here - we only test if the method is called
  }
  render() {
    const spinner = (<Loader id="spinner" color="#FFFFFF" size="8px" margin="0px" />);
    return (
      <button
