Importare l'SDK e i moduli client e chiamare l'API.

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

const run = async () => {
  // Request parameters for PutRule.
  // https://docs.aws.amazon.com/eventbridge/latest/APIReference/API_PutRule.html#API_PutRule_RequestParameters
  const command = new PutRuleCommand({
    Name: process.env.CLOUDWATCH_EVENTS_RULE,

    // The event pattern for the rule.
    //  Example: {"source": ["my.app"]}
    EventPattern: process.env.CLOUDWATCH_EVENTS_RULE_PATTERN,

    // The state of the rule. Valid values: ENABLED, DISABLED
    State: "ENABLED",
  });

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

export default run();

Creare il client in un modulo separato ed esportarlo.

import { CloudWatchEventsClient } from "@aws-sdk/client-cloudwatch-events";

export const client = new CloudWatchEventsClient({});

// Load the AWS SDK for Node.js
var AWS = require("aws-sdk");
// Set the region
AWS.config.update({ region: "REGION" });

// Create CloudWatchEvents service object
var cwevents = new AWS.CloudWatchEvents({ apiVersion: "2015-10-07" });

var params = {
  Name: "DEMO_EVENT",
  RoleArn: "IAM_ROLE_ARN",
  ScheduleExpression: "rate(5 minutes)",
  State: "ENABLED",
};

cwevents.putRule(params, function (err, data) {
  if (err) {
    console.log("Error", err);
  } else {
    console.log("Success", data.RuleArn);
  }
});
