ServerBridge

The ServerBridge is the networking layer that connects in-memory HTTP servers to the browser’s request pipeline. It uses a Service Worker to intercept fetch requests from preview iframes and route them to the appropriate server handler inside the jiki container, without real network round-trips.

When a framework dev server listens on a port, the ServerBridge registers that port. Any subsequent fetch requests targeting that port are intercepted by the Service Worker, forwarded to the in-memory handler, and the response is returned to the browser as if it came from a real server.

Setup

The Service Worker file must be served from your application’s public directory. jiki provides a helper to register it:

import { registerServiceWorker } from "jiki/sw";

await registerServiceWorker("/sw.js");
