Wrap The Root Of A Gatsby App In A Component

Each component that is defined in the pages directory of a Gatsby app will be generated into a separate static page. Each of these pages is meant to stand on its own. Nevertheless, there is still a behind-the-scenes root component above all of these pages. There are cases where’d you like to wrap this root component with some other component, such as a Redux Provider.

This can be done using the wrapRootElement hook from the Browser API in the gatsby-browser.js file.

// gatsby-browser.js
import React from 'react';
import { Provider } from 'react-redux';

import store from './src/store';

export const wrapRootElement = ({ element }) => {
  return (

Each page and each component in your Gatsby app will now be downstream from a Redux provider meaning that they can connect to the Redux store as needed. You can use this technique for any top-level component that need to be wrapped around the entire app.
