OFF-SQS: Manage Amazon SQS and RabbitMQ on node.js

This easy manager provides the basic functionality to use Amazon SQS in production enviroment and RabbitMQ in development enviroment. To start using it just clone it or install it via npm npm install off-sqs-debearloper.

Amazon SQS settings

You only need edit the aws-config.json adding your own keys:

    {
        "accessKeyId": "STRING",
        "secretAccessKey": "STRING",
        "region": "STRING"
    }

Note: that every operation checks first if the Queue exists, if not it'll create it.**

RabbitMQ settings

To work with RabbitMQ, you need to install the Server. We recommend you to do it with homebrew, so you dont have to set up the server manually when you are in the development environment.

Before installing make sure you have the latest brews: brew update

Then, install RabbitMQ server with:

brew install rabbitmq

Enviroments

development is the enviroment by default. If you want to use production or qa execute your node app in this way:

NODE_ENV=production node yourApp.js
//or
NODE_ENV=qa node yourApp.js
