# Data fetch example
|
|
|
|
## 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 data-fetch data-fetch-app
|
|
# or
|
|
yarn create next-app --example data-fetch data-fetch-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/data-fetch
|
|
cd data-fetch
|

## The idea behind the example
|
|
|
|
Next.js was conceived to make it easy to create universal apps. That's why fetching data
|
|
on the server and the client when necessary is so easy with Next.
|
|
|
|
Using `getInitialProps` fetches data on the server for SSR and then on the client when the component is re-mounted (not on the first paint).
