Build SVG Icon components with React (bicolor and fade state)

IconComponent.js

import { Component } from 'react';
import PropTypes from 'prop-types';

class IconComponent extends Component {
  render() {
    const { size, faded } = this.props;

    const colors = {
      primaryColor: faded ? '#dfdfe7' : '#00cc99',
      secondaryColor: faded ? '#dfdfe7' : '#f5a623',
    };

    return this.renderSvgIcon({ ...colors, size });
  }
}

IconComponent.defaultWidthSize = 32;

IconComponent.getDimensions = (width, height, size = IconComponent.defaultWidthSize) => ({
  width: width >= height ? size : size / height * width,
  height: height >= width ? size : size / width * height,
  viewBox: `0 0 ${width} ${height}`,
});

IconComponent.defaultProps = {
  faded: false,
  size: IconComponent.defaultWidthSize,
};

IconComponent.propTypes = {
  faded: PropTypes.bool,
  size: PropTypes.number,
};

export default IconComponent;

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import PictureIcon from './PictureIcon';

ReactDOM.render(
  <PictureIcon faded size={128} />,
  mountNode
);

PictureIcon.js

import React from 'react';
import IconComponent from './IconComponent';

class PictureIcon extends IconComponent {
  // eslint-disable-next-line class-methods-use-this
  renderSvgIcon({ primaryColor, secondaryColor, size }) {
    const dimensions = IconComponent.getDimensions(37, 37, size);

    return (
      <svg {...dimensions} xmlns="http://www.w3.org/2000/svg">
        <g fill="none" fillRule="evenodd">
          <g transform="translate(1 1)" strokeLinejoin="round" strokeWidth="2">
            <path
              stroke={secondaryColor}
              d="M23.068 23.068l-4.773-11.932-3.977 8.75-3.977-4.772-4.773 7.954M.795 23.068h27.046"
            />
            <circle stroke={secondaryColor} cx="7.955" cy="7.955" r="2.386" />
            <path stroke={primaryColor} d="M.795.795H27.84V27.84H.795z" />
            <path stroke={primaryColor} strokeLinecap="round" d="M31.035 10.152l3.17.288-2.169 23.765-23.765-2.169" />
          </g>
          <path d="M-1-1h38v38H-1z" />
        </g>
      </svg>
    );
  }
}

export default PictureIcon;

@DaPo I use a svgo (npm cli package) also used by SVGOMG 😃.
