Prefetch
Resource Prefetching
A browser hint that downloads resources in the background before they are needed, improving perceived navigation speed.
Détail technique
Prefetch is part of the web platform's core infrastructure. Modern browsers implement browser through standardized Web APIs, ensuring consistent behavior across Chrome, Firefox, Safari, and Edge. The relevant specifications are maintained by the W3C, WHATWG, or IETF. Understanding the underlying protocol or mechanism helps developers use prefetch correctly, avoid common pitfalls, and optimize for performance and security.
Exemple
```javascript
// Prefetch: web API example
const response = await fetch('/api/resource');
const data = await response.json();
console.log(data);
```
