NOTHS Global Components

Frontend global components used at www.notonthehighstreet.com

Components included

• NOTHS Header
• NOTHS Footer
• NOTHS Copyright statement

Background & context

Global components are components which will be on most pages of the site.

These components use mainly vanilla javascript and do not use any framework. This is to reduce the footprint on the consuming application.

The components are written in ES2015 and use Rollup for compilation and minification.

Component usage

Consuming

HTML

The NPM module includes pre bundled HTML files for Header, Navigation, Footer and Copyright components. To include these copy the file contents from node_modules/noths-global-components/compiled/dist/[header|navigation|footer|copyright].html and insert into your page where required.

React

import React from 'react';
import { Header, Navigation, Footer, Copyright } from 'noths-global-components';

export class App extends React.Component {
  render() {
    return (
      <div id="app">
        <Header />
        <Navigation />
          <h1>hello world</h1>
        <Footer />
        <Copyright />
      </div>
    );
  }
}

NOTE: These components are created using dangerouslySetInnerHTML of their counterpart HTML component. There is no JS logic in them, it's simply a wrapper to aid integrating components into React apps.

Triggering the Mobile Navigation

The Header components handles triggering the Mobile navigation when the burger menu is click by default. But if you need to toggle the Mobile navigation from another element you will need to fire a TOGGLE_NAVIGATION event.

Here is an example:

  const event = document.createEvent('Event');
  event.initEvent('TOGGLE_NAVIGATION', true, true):
  document.dispatchEvent(event);

Tracking / GTM / Analytics

A Google Tag Manager (GTM) container has been set up to track global component events (Global Components - GTM-WJKV2N3). To ensure that these events continue to track in your service, you will need to push a dataLayer variable with the environment your service is running on as soon as possible on the page. This allows us to know which Google Analytics account to send the tracked event to.

You will need something like the following in your service:

<script>
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({ environment: '<development|staging|production>' });
</script>
