@threadplane/render · generative UI

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. Unknown specs degrade gracefully — no surprises.

How it works

Schema on the wire, your design system on screen

The agent emits a spec. Your registry, state, and handlers resolve it — and your own Angular components render it.

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.

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.

Developer Experience

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"
/>
