<h1>The Idea Behind This Example</h1>
|
|
<p>
|
|
<a href='https://www.apollographql.com/client/'>Apollo</a> is a GraphQL client that
|
|
allows you to easily query the exact data you need from a GraphQL
|
|
server. In addition to fetching and mutating data, Apollo analyzes your
|
|
queries and their results to construct a client-side cache of your data,
|
|
which is kept up to date as further queries and mutations are run,
|
|
fetching more results from the server.
|
|
</p>
|
|
<p>
|
|
In this simple example, we integrate Apollo seamlessly with{' '}
|
|
<a href='https://github.com/zeit/next.js'>Next</a> by wrapping our pages
|
|
inside a{' '}
|
|
<a href='https://facebook.github.io/react/docs/higher-order-components.html'>
|
|
higher-order component (HOC)
|
|
</a>. Using the HOC pattern we're able to pass down a central store of
|
|
query result data created by Apollo into our React component hierarchy
|
|
defined inside each page of our Next application.
|
|
</p>
|
|
<p>
|
|
On initial page load, while on the server and inside getInitialProps, we
|
|
invoke the Apollo method,{' '}
|
|
<a href='https://www.apollographql.com/docs/react/features/server-side-rendering.html#getDataFromTree'>
|
|
getDataFromTree
|
|
</a>. This method returns a promise; at the point in which the promise
|
|
resolves, our Apollo Client store is completely initialized.
|
|
</p>
|
|
<p>
|
|
This example relies on <a href='http://graph.cool'>graph.cool</a> for
|
|
its GraphQL backend.
