# Apollo Example
|
|
|
|
## Demo
|
|
|
|
https://next-with-apollo.now.sh
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-apollo with-apollo-app
|
|
# or
|
|
yarn create next-app --example with-apollo with-apollo-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example:
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-apollo
|
|
cd with-apollo
|
|
```
|
|
|
|
Install it and run:
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```
|
|
|
|
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download)):
|
|
|
|
```bash
|
|
now
|
|
```

## The idea behind the example
|
|
|
|
[Apollo](https://www.apollographql.com/client/) 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.
|
|
|
|
In this simple example, we integrate Apollo seamlessly with Next by wrapping our *pages/_app.js* inside a [higher-order component (HOC)](https://facebook.github.io/react/docs/higher-order-components.html). 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.
|
|
|
|
On initial page load, while on the server and inside `getInitialProps`, we invoke the Apollo method, [`getDataFromTree`](https://www.apollographql.com/docs/react/features/server-side-rendering.html#getDataFromTree). This method returns a promise; at the point in which the promise resolves, our Apollo Client store is completely initialized.
|
|
|
|
This example relies on [graph.cool](https://www.graph.cool) for its GraphQL backend.
