# Fizz Fixtures
```

A set of basic tests for Fizz primarily focused on baseline performance of legacy renderToString and streaming implementations.

```
## Setup
```

To reference a local build of React, first run `npm run build` at the root

```
of the React project. Then:
```
```
```
```
```
cd fixtures/fizz
```
```
yarn
```
```
yarn start
```
```
```
```

The `start` command runs a webpack dev server and a server-side rendering server in development mode with hot reloading.

**Note: whenever you make changes to React and rebuild it, you need to re-run `yarn` in this folder:**

```
```
```
```
yarn
```
```
```
```

If you want to try the production mode instead run:

```
```
```
```
yarn start:prod
```
```
```
```

This will pre-build all static resources and then start a server-side rendering HTTP server that hosts the React app and service the static resources (without hot reloading).
