CloudWatch Events examples using SDK for JavaScript (v3)

Import the SDK and client modules and call the API.

import { PutEventsCommand } from "@aws-sdk/client-cloudwatch-events";
import { client } from "../libs/client.js";

const run = async () => {
  const command = new PutEventsCommand({
    // The list of events to send to Amazon CloudWatch Events.
    Entries: [
      {
        // The name of the application or service that is sending the event.
        Source: "my.app",

        // The name of the event that is being sent.
        DetailType: "My Custom Event",

        // The data that is sent with the event.
        Detail: JSON.stringify({ timeOfEvent: new Date().toISOString() }),
      },
    ],
  });

  try {
    return await client.send(command);
  } catch (err) {
    console.error(err);
  }
};

export default run();

Create the client in a separate module and export it.
