  +A set of convenience utilities for using `urql` with Next.js.
  ### Motivation
  Using GraphQL with server-side rendering in React is a challenging problem. Currently, React has no support for `Suspense` for data fetching on the server. To get around this, a prepass step can be used to walk the tree (or a subsection of the tree) of your React application and suspend when it encounters thrown `Promise`s. For more information, check out [`react-ssr-prepass`](https://github.com/FormidableLabs/react-ssr-prepass).
  -`next-urql` handles integrating this prepass step for you, such that your NextJS application using `urql` will prefetch your GraphQL queries on the server before sending down markup to the Client.
