Fetch ESM

Sample for configuring a Temporal project with TypeScript and ES Modules.

Fundamental difference from CommonJS:

package.json has "type": "module" attribute.
tsconfig.json outputs in esnext format.
Imports must include the .js file extension.

Running this sample

temporal server start-dev to start Temporal Server.
npm install to install dependencies.
npm run start.watch to start the Worker.
In another shell, npm run workflow to run the Workflow.

The Workflow should return:

Hello, Temporal!
