The shell hosting your app and others over live channels

@platform/sdk

The framework-agnostic client your Angular app uses to join the platform — one handshake, then intents, surfaces, modals, and a shared session.

Start the quickstart API reference

What this is

@platform/sdk is the client an app installs to be loaded by the platform shell. Your app runs in its own iframe; the SDK performs an origin-validated handshake and hands you a small, promise-based client for everything cross-app: invoking and providing intents, hosting and exposing surfaces, opening shell-brokered modals, reading the session, and reporting telemetry.

You build an ordinary Angular app. The SDK never imports a UI framework — you wire it into Angular DI through an injection token and keep writing Angular.

Tutorial Install to first render in under fifteen minutes, running standalone before you ever touch a shell.

How-to guides Task recipes: surfaces, modals, intents, roles, routing, and zoneless change detection.

Explanation The mental models: isolation, contracts, the surface/modal/intent/event split, advisory auth, and versioning.

API reference Every app-facing symbol, generated from the SDK source.

A taste

import { bootstrap } from "@platform/sdk";
import { standalonePlatform } from "@platform/dev-harness";

void bootstrap({
  contract,
  app: () => import("./app/app").then((m) => m.App),
  fallback: () => standalonePlatform({ appId: "my-app" }),
  mountApp: (app, platform) =>
    bootstrapApplication(app, { providers: [{ provide: PLATFORM, useValue: platform }] }),
});

Authentication appears here only as the SDK surfaces it — the advisory session snapshot and hasRole() for affordances. Your backend remains the gate; see Advisory auth vs the backend gate.
