# Example app using shared modules

## 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 shared-modules shared-modules-app
# or
yarn create next-app --example shared-modules shared-modules-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/shared-modules
cd shared-modules

## The idea behind the example

This example features:

* An app with two pages which has a common Counter component
* That Counter component maintain the counter inside its module. This is used primarily to illustrate that modules get initialized once and their state variables persist in runtime
