power-sqs
Power-SQS is a set of powerful functions to deal with AWS SQS. It includes stream to read messages, move messages from one SQS to another or to a persistent data store.
If you just want to use sink operations, there is an option availble to use them via cli. Please see power-sqs-cli
How to install
npm install power-sqs
yarn add power-sqs
How To Use
Power SQS provides following functions to deal with AWS SQS
Reader
getSQSReader
Returns a readable stream of messages with long polling of 10 seconds. The object mode is enabled in the stream and pushes single message across the pipe.
const {getSQSReader} = require("power-sqs");
const config = {"url": "your sqs url"};
const sqsReader = getSQSReader(config);
// returns a Node.js readable stream.
sqsReader.pipe("stream of your choice.")
getSQSPowerReader
Returns a highland stream. The stream can then be used to apply transformers like filter, map, find and etc to generate a stream of data before piping it to another stream.
Please see highland transformers for more information.
const {getSQSPowerReader} = require("power-sqs");
const config = {"url": "your sqs url"};
const sqsReader = getSQSPowerReader(config);
// returns a Node.js readable stream.
sqsReader.filter(() => {
// filter logic
}).pipe("stream of your choice");
getSQSBulkReader
Returns a readable stream of messages with long polling of 10 seconds. The object mode is enabled in the stream and returns the complete data object returned from the AWS.
The messgages in the pushed chunk can be accessed via the the Messages. It only pushes the data if it has any number of Messages attached to it otherwise it will keep on polling the SQS.
const {getSQSBulkReader} = require("power-sqs");
const config = {"url": "your sqs url"};
const sqsReader = getSQSBulkReader(config);
// returns a Node.js readable stream.
sqsReader.pipe("stream of your choice.")
DeleteMessages
Allows you to delete the messages in batch
const {deleteMessages} = require("power-sqs");
const queueUrl = "your sqs url";
const messages = [{}] // array of messages you want to delete
return deleteMessages(queueUrl, messages)
.then(res => console.log(res));
SendMessages
Allows you to send the messages in batch
const {sendMessages} = require("power-sqs");
const queueUrl = "your sqs url";
const messages = [{"foo": "bar"}] // data you want to send as messages
return sendMessages(queueUrl, messages)
.then(res => console.log(res));
SendFifoMessages
Allows you to send the messages in batch
const {sendFifoMessages} = require("power-sqs");
const queueUrl = "your sqs url";
const group = "groupid";
const messages = [{"foo": "bar"}] // data you want to send as messages
return sendFifoMessages(queueUrl, group, messages)
.then(res => console.log(res));
receiveMessages
Allows you to receive the messages from a sqs. If you are looking for something to poll continuously, have a look at other reader functions which provide streaming and filtering options too.
const {sendMessages} = require("power-sqs");
const queueUrl = "your sqs url";
return receiveMessages(queueUrl)
.then(res => console.log(res));
Sink
initSinkToSQS
Allows you to move messages from one SQS to another in same AWS Account.
const {initSinkToSQS} = require("power-sqs");
const source = {"url": "your sqs url"};
const destination = {"url": "your sqs url"};
const config = {source, destination};
initSinkToSQS(config);
Examples
some of the examples related to specifically single operations like sendMessages, deleteMessages etc are provided in examples directory.
