# CPU async rendering demo
```
```
## What is this fixture?
```

This is a demo application based on [Dan Abramov's](https://github.com/gaearon) recent [JSConf Iceland talk](https://reactjs.org/blog/2018/03/01/sneak-peek-beyond-react-16.html) about React.

It depends on a local build of React and enables us to easily test async "time slicing" APIs in a more "real world app" like context.

```
## Can I use this code in production?
```

No. The APIs being tested here are unstable and some of them have still not been released to NPM. For now, this fixture is only a test harness.

There are also known bugs and inefficiencies in main so **don't use this fixture for demonstration purposes either yet**. Until they are fixed, this fixture is **not** indicative of React async rendering performance.

```
## How do I run this fixture?
```
```
### From npm version
```
```
```
```
```
# 1: Install fixture dependencies
```

cd fixtures/unstable-async/time-slicing/

```
yarn
```
```
# 2: Run the app
```
```
yarn start
```
```
```
```
```
### From React source code
```
```
```shell
```
```
# 1: Build react from source
```
```
cd /path/to/react
```
```
yarn
```

yarn build react-dom/index,react/index,react-cache,scheduler --type=NODE

```
# 2: Install fixture dependencies
```

cd fixtures/unstable-async/time-slicing/

```
yarn
```
```
# 3: Copy React source code over
```
```
yarn copy-source
```
```
# 3: Run the app
```
```
yarn start
```
```
```
```
