eventbridge-bulk-loader

AWS EventBridge Bulk Loader (WORK IN PROGRESS)

A set of functions to help sending bulk messages in sequence or parallel to AWS EventBridge.

How to install

npm install eventbridge-bulk-loader

Running the tests

npm test

Getting started

Basic syntax is:

const {sendBatchedMessages, sendBatchedMessagesInParallel} = require("eventbridge-bulk-loader")();

const messages = [
  {
    "Id": "1",
    "MessageBody": '{"key1": "value1"}'
  },
  {
    "Id": "2",
    "MessageBody": '{"key2": "value2"}'
  }
];

// this needs to be in async function
const response = await sendBatchedMessages("someQueueUrl", messages);
console.log(response)

// OR you can use normal promise style as well.
sendBatchedMessages("someQueueUrl", messages)
  .then(response => console.log(response));

In case you need to inject the aws-sdk with custom settings. It can be done like this

const aws = require("aws-sdk");
const sqsClient = new aws.SQS();
const {sendBatchedMessages, sendBatchedMessagesInParallel} = require("eventbridge-bulk-loader")(sqsClient);
