sqs-abstraction

sqs-abstraction is a node module for abstracting development against amazon's simple queue service, by simply employing a stratergy, to swap out the production (sqs) implementation with a file system implementation dependent on the presence of the NODE_ENV === 'production' environment variable.

It uses long polling at a configurable interval in order to monitor the queue in definately.

Installation

$ npm install sqs-abstraction

Examples

Configuration

var config = {
  name: 'QUEUE NAME',
  interval: 1000 * 60 * 10, // MONITOR INTERVAL in milliseconds (default 10min)
  config: {
    // Your AWS SQS configuration
  }
}

Initialisation

var Queue = require('sqs-abstraction');
var queue = new Queue(config);

Check the queue for messages one time only;

queue.read(-1);

Monitor the queue for messages each config.interval

queue.read();

Handle incoming messages

queue.on('data', function(msg){
  // ...
});

Write messages to the queue.

queue.write(json, function(err) {
  // ...
});
