The idea behind the example

Relay Modern is a new version of Relay designed from the ground up to be easier to use, more extensible and, most of all, able to improve performance on mobile devices. Relay Modern accomplishes this with static queries and ahead-of-time code generation.

In this simple example, we integrate Relay Modern seamlessly with Next by wrapping our pages inside a higher-order component (HOC). Using the HOC pattern we're able to pass down a query result data created by Relay into our React component hierarchy defined inside each page of our Next application. The HOC takes options argument that allows to specify a query that will be executed on the server when a page is being loaded.

This example implements a simple graphql server using express, showing a custom graphql server integrated to next.js and relay modern.
