Each component in the mappings object will receive the following props:

• attrs - an object with all the attributes of the tag
• style - styles for the component

Example

For quick working demo, use Expo app to preview the example: https://expo.io/@usrbowe2/jumbo-html

import * as React from 'react';
import { StyleSheet } from 'react-native';
import { HTMLRenderer } from 'react-native-jumbo-html';
import CustomImage from './CustomImage';

const html = `
  <p>Hello world</p>
`;

const mappings = {
  img: CustomImage
};

export default function App() {
  return (
    <HTMLRenderer
      html={html}
      sheet={styles}
      mappings={mappings}
    />
  );
}

const styles = StyleSheet.create({
  a: {
    color: 'blue'
  },
  '.red': {
    color: 'red'
  }
});

RendererMappings

The default list of mappings. You can reuse the mappings when adding additional functionality and don't have to re-implement the components.
