# Example app with page loading indicator
|
|
|
|
## 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-loading with-loading-app
|
|
# or
|
|
yarn create next-app --example with-loading with-loading-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/with-loading
|
|
cd with-loading
|
|
```
|
|
|
|
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
|
|
|
|
Sometimes when switching between pages, Next.js needs to download pages(chunks) from the server before rendering the page. And it may also need to wait for the data. So while doing these tasks, browser might be non responsive.
|
|
|
|
We can simply fix this issue by showing a loading indicator. That's what this examples shows.
|
|
|
|
It features:
|
|
|
|
* An app with two pages which uses a common [Header](./components/Header.js) component for navigation links.
|
|
* Using `next/router` to identify different router events
|
|
* Uses [nprogress](https://github.com/rstacruz/nprogress) as the loading indicator.
