[abutterworth]

Usage

To install frontend-component-footer-edx into your project

   npm i --save @edx/frontend-component-footer-edx

Component Usage

   import Footer from '@edx/frontend-component-footer-edx';
   import footerMessages from '@edx/frontend-component-footer-edx/src/i18n/index';

   ...

   <Footer
      handleAllTrackEvents={(eventName, properties) => {/* track click event */}}
      onLanguageSelected={(languageCode) => {/* set language */}}
      supportedLanguages={[
         { label: 'English', value: 'en'},
         { label: 'Español', value: 'es' },
      ]}
   />

• handleAllTrackEvents (required)
• onLanguageSelected (optional)
• supportedLanguages (optional)

For what it's worth, you should be able to use frontend-base in this example app, like the header repos. (I don't feel strongly)

I figure this is just as easy.
