For standard React SPAs, add the script to your `index.html`.
---
## Method 1: index.html (Recommended)
The simplest approach is to add the Pulse script directly to your HTML entry point.
```html filename="public/index.html"
My React App
```
## Method 2: Programmatic injection via useEffect
If you prefer to inject the script programmatically (e.g. only in production), use a `useEffect` hook.
```tsx filename="src/App.tsx"
import { useEffect } from 'react'
function App() {
useEffect(() => {
if (process.env.NODE_ENV === 'production') {
const script = document.createElement('script')
script.defer = true
script.setAttribute('data-domain', 'your-site.com')
script.src = 'https://pulse.ciphera.net/script.js'
document.head.appendChild(script)
}
}, [])
return Hello World
}
```
