AppExtras component#

The AppExtras component is a general use insertion point for things like analytics, general purpose code spanning the whole application or third party services code. AppExtras component inserts will be rendered by the App component.

How to use it#

You can either use it by overriding it via component shadowing by placing a custom src/customizations/components/theme/AppExtras/AppExtras.jsx...

Or you can use the new key of config.settings, the appExtras. This is a list of registrations, each registration is an object with:

  • match: The match key is for objects compatible with react-router's matchPath, so it can be either a simple string or a match object.

  • component. Use the component to link the component to be used.

  • props: Extra props to be inject to the actual component used.

For example:

import { settings as defaultSettings } from '@plone/volto/config'

export settings = {
  appExtras: [
      match: '',
      component: GoogleAnalyticsPing
      props: {
        'google-tag': '123456'
      match: {
        path: '/blogs',
        exact: true,
      component: WordClouds
      path: '/blog/**/edit',
      component: ExtraToolbarButton,

You can use this to render, for example, <Portal> components to be inserted somewhere in the website.
