Shared, framework-agnostic TanStack Router bridge base for XMachines Play.

License: MIT Version

TanStack Router gives React and Solid the same navigate, load, and history surface. Therefore the complete bridge implementation lives here, in TanStackRouterBridgeBase. That class extends RouterBridgeBase from @xmachines/play-router. Each framework adapter package makes a subclass of it, and binds its own router type.

This package has no TanStack runtime dependency. TanStackRouterLike is a type-only interface. It describes the small router surface that the bridge uses.

Who consumes it

Usage

import { createMachine } from "xstate";
import { definePlayer, formatPlayRouteTransitions } from "@xmachines/play-xstate";
import { createRouteMap } from "@xmachines/play-router";
import { TanStackRouterBridgeBase } from "@xmachines/play-tanstack-router";


const machine = createMachine(
  formatPlayRouteTransitions({
    id: "app",
    initial: "home",
    states: {
      home: { id: "home", meta: { route: "/" } },
      about: { id: "about", meta: { route: "/about" } },
    },
  }),
);


const actor = definePlayer({ machine })();
actor.start();


const routeMap = createRouteMap(machine);


export class MyTanStackBridge extends TanStackRouterBridgeBase {}


// router: your TanStack Router instance (from the React or Solid createRouter)
const bridge = new MyTanStackBridge(router, actor, routeMap);
bridge.connect();
// Disconnect the bridge at teardown
bridge.disconnect();

Corrective navigation and a mounted <RouterProvider>

The bridge subscribes to router.history, and it calls router.load() for every history event. The bridge waits for that load() promise before it synchronizes the actor. The wait is necessary for a mounted <RouterProvider>: its Transitioner component defers router.updateLatestLocation() into the startTransition of the framework. Without the wait, router.latestLocation still holds the previous href while the bridge runs. A corrective navigation for a refused URL then looks like a navigation to the same URL, and commitLocation of TanStack writes nothing to the browser history. The refused URL then stays in the address bar. With the wait, router.latestLocation is current, and the correction reaches the history. The bridge therefore works with a mounted <RouterProvider> and also without one.

A burst of history events keeps its order: each event takes a sequence number, and a deferred synchronization runs only while its number is still the newest one. A disconnect() call retires every synchronization that still waits.

Exports

  • TanStackRouterBridgeBase — the concrete bridge base class. Use it directly, or make a subclass of it
  • TanStackRouterLike — the TanStack router surface, as a type-only interface
  • TanStackRouteMapLike — the narrow route-map surface that the bridge requires

@xmachines/play-tanstack-router

The shared, framework-agnostic TanStack Router bridge base for XMachines Play. @xmachines/play-tanstack-react-router and @xmachines/play-tanstack-solid-router use it. Each of them makes a subclass of TanStackRouterBridgeBase, and the subclass binds its own router type.
