interfaceContext{readonlyappName: string;}interfacePersonContext{name: string;age: number;}classPersonRenderActivityextendsActivity<PersonContext&Context>{protectedonExecute(cancellationToken: CancellationToken,context: PersonContext&Context): void|Promise<void>{console.log(`${context.appName} The ${context.name} is ${context.age} years old.`);}}constworkflow=newContextActivity<Context,PersonContext>({initContext: {name: "Noname",age: 42},child: newWhileActivity({condition: newCodeActivity((ctx)=>{console.log("Checking condition in CodeActivity");ctx.age++;if(ctx.age>45){ctx[WhileActivity.Done]();}}),child: newSequenceActivity({children: [newConsoleLogActivity({text: "one"}),newDelayActivity({durationMilliseconds: 100}),newConsoleLogActivity({text: "two"}),newDelayActivity({durationMilliseconds: 200}),newConsoleLogActivity({text: "three"}),newDelayActivity({durationMilliseconds: 300}),newPersonRenderActivity()]})})});console.log("LocalWorkflowRuntime.invoke(activity, context)");constappContext: Context={appName: "example1"};awaitLocalWorkflowRuntime.invoke(dummyCancellationToken,workflow,appContext);

Result:
