@threadplane/render

Generative UI without a second framework.

Server-emitted JSON specs render into Angular components you already own. Vercel json-render and Google A2UI both supported. Per-component fallback, readiness gate, no surprises.

Schemas

One spec. Your components.

The agent emits structured UI as JSON. @threadplane/render maps each spec node to one of your Angular components — so the design system stays yours, and the agent gets to assemble it.

  • Vercel json-render adapter
  • Google A2UI protocol
  • Component registry — declare once, use everywhere
  • Server schema, client validation

Fallbacks

Readiness gate + per-component fallback.

When the agent emits a spec your registry doesn't know how to render, @threadplane/render falls back gracefully — and surfaces it to your observability layer. No mystery white screens.

  • Per-component fallback API
  • Readiness gate holds renders until safe
  • Telemetry hook for render events
  • Streaming partial renders supported

Generative UI in a few lines

Registry Setup
import { defineAngularRegistry } from '@threadplane/render';
import { TableComponent } from './table.component';
import { ChartComponent } from './chart.component';

const registry = defineAngularRegistry({
  table: TableComponent,
  chart: ChartComponent,
  form: FormComponent,
});
Template Binding
<render-spec
  [spec]="agentOutput()"
  [registry]="registry"
  [store]="stateStore"
/>
