Apollo's getDataFromTree is supposed to be called during the server side rendering.
Being called in browser it fires an unnecessary fake render process and blocks components from rendering with loading=true.
Also there was a mistake in this code:
// `getDataFromTree` renders the component first, the client is passed off as a property.
// After that rendering is done using Next's normal rendering pipeline
this.apolloClient = props.apolloClient || initApollo(props.apolloState.data)
**Apollo** component is not rendered by getDataFromTree actually, it renders the **App** directly, thus props.apolloClient will always be undefined.
This example was discussed here: https://github.com/zeit/next.js/issues/387.
I had some trouble to get server side rendering with the AWSAppSyncClient working. I finally found a solution in https://github.com/awslabs/aws-mobile-appsync-sdk-js/issues/82 but it might be worth to share it here as well. Instead of adding a big code block to each file I'll just refer to this Pull Request.

In case you want to use the `AWSAppSyncClient` you just need to replace the `create()` function with this function:
```jsx
import AWSAppSyncClient from 'aws-appsync';
import { AUTH_TYPE } from 'aws-appsync/lib/link/auth-link';
function create(initialState) {
const client = new AWSAppSyncClient({
url: AWS_AppSync.graphqlEndpoint,
region: AWS_AppSync.region,
auth: {
type: AUTH_TYPE.API_KEY,
apiKey: AWS_AppSync.apiKey,
// Amazon Cognito Federated Identities using AWS Amplify
//credentials: () => Auth.currentCredentials(),
// Amazon Cognito user pools using AWS Amplify
// type: AUTH_TYPE.AMAZON_COGNITO_USER_POOLS,
// jwtToken: async () => (await Auth.currentSession()).getIdToken().getJwtToken(),
},
disableOffline: true,
}, {
cache: new InMemoryCache().restore(initialState || {}),
ssrMode: true
});
return client;
}
```
* Add new apollo example
* Update readme
* Update with-apollo to use _app.js
* Move withData to _app
* Make SSR work again
* Remove withData
* Use HOC to provide apolloClient
* Spread pageprops
This was causing react-apollo to crash on any SSR page that needed the page's query to make the GraphQL queries.
It's magically passed on the client, but we have to manually pass it to the composed component here
* pass down getInitialProps ctx to ComposedComponent
* pass apollo client instance directly to getDataFromTree instead of through the ApolloProvider wrapper.
* Avoid redundant empty serverState initialization (It's always initialized)
The serverState variable definition did not include the data node, which
may cause parsing errors on the client-side.
- add data: { } on line 23 within the apollo: { } object
Prior to react-apollo 2.0 createNetworkInterface accepted the credentials option in {opt: {credentials: 'policy'}}. HttpLink accepts it as {credentials: 'policy'}.
* [fix] with-apollo: Cannot read property 'data'
When we create the initial serverState, we need to create the
eventual construct of the Apollo Data to reside within
Later in the constructor this allows for the initApollo to either
be generated from SSR, or to init from scratch.
Fixes
> Cannot read property 'data' of undefined
> TypeError: Cannot read property 'data' of undefined
* [refactor] with-apollo: reduce init `serverState`
No need to explicitly set `data` as empty.
This trims up 4 lines. 😀️
