Class: AgentickService ​

Defined in: angular/src/agentick.service.ts:90

Angular service wrapping AgentickClient with signals.

Lower-level than ChatSessionService — use this when you need direct client access (sessions, channels, raw events). For chat UIs, prefer ChatSessionService which composes higher-level chat primitives.

Example ​

typescript
@Component({
  providers: [provideAgentick({ baseUrl: '/api/v2' })],
  template: `
    @if (agentick.isConnected()) {
      <div>{{ agentick.text() }}</div>
      <button (click)="send('hello')">Send</button>
    }
  `,
})
export class ChatComponent {
  agentick = inject(AgentickService);

  constructor() {
    this.agentick.subscribe('session-123');
  }

  send(text: string) {
    this.agentick.send(text);
  }
}
