Queue consumer loop

The consumer of the messages coming from a queue-like source.

Usage

To consume messages you provide a callback to consume function. Example:

const queueConsumerLoop = require('queue-consumer')({
    queue: <the_queue>
});
const callback = function(messageBody, messageAttributes, messageId) {
    // handle message
};
queueConsumerLoop(callback);

this will run inifnite loop of callback invocations for each message. The messages will be automatically deleted as long as callback didn't throw an exception.

The queue interface

The queue is assumed to be an object with following functions:

• getNextNonEmptyBatch() - returns next batch of messags to be processed
• deleteMessage(message) - deletes given message (marks as processed)
