23## Usage
45```tsx
6/** @jsxImportSource https://esm.sh/react */
7import { render, React } from "https://esm.town/v/jxnblk/ReactStream";
89function App() {
10const [count, setCount] = React.useState(0);
11return (
12<html>
13<body>
14<h1>ReactStream</h1>
15<p>React SSR with client-side hydration in Val Town</p>
16<pre>{count}</pre>
17<button onClick={() => setCount(count - 1)}>-</button>
25```
2627[Live example](https://www.val.town/v/jxnblk/ReactStreamDemo)
2829To render static HTML without hydration, pass `false` as the second argument.

112113React requires matching versions for SSR and hydration.
114Import `React` from `https://esm.town/v/jxnblk/ReactStream` to ensure your component uses the same version as this library (currently react@18.3.1).
