@terajs/hub-signalr

SignalR transport adapter for Terajs sync hub workflows.

This is a first-party realtime adapter. The socket.io and websockets packages use the same runtime transport contract and expose the same high-level transport shape.

Install

npm install @terajs/hub-signalr @microsoft/signalr

Usage

import { createSignalRHubTransport } from "@terajs/hub-signalr";
import { invalidateResources, setServerFunctionTransport } from "@terajs/runtime";

const hub = await createSignalRHubTransport({
  url: "https://api.example.com/chat-hub",
  autoConnect: true,
  retryPolicy: "exponential"
});

hub.subscribe((message) => {
  if (message.type === "invalidate") {
    void invalidateResources(message.keys);
  }
});

setServerFunctionTransport(hub);

Transport shape

The created transport implements the runtime ServerFunctionTransport contract and also exposes:

• connect()
• disconnect()
• isConnected()
• subscribe(listener)

Diagnostics

The adapter emits structured hub:* debug events for DevTools and diagnostics, including connect, disconnect, push, sync-start, sync-complete, and error flows.
