How to spawn an Activity Execution in TypeScript

To spawn an Activity Execution, you must retrieve the Activity handle in your Workflow.

import { proxyActivities } from '@temporalio/workflow';
// Only import the activity types
import type * as activities from './activities';

const { greet } = proxyActivities<typeof activities>({
  startToCloseTimeout: '1 minute',
});

// A workflow that calls an activity
export async function example(name: string): Promise<string> {
  return await greet(name);
}

This imports the individual Activities and declares the type alias for each Activity.
