## Features
- Simple API, just a `publish()` and a `subscribe()`.
- Support for AMQP and HTTP, same api which makes them interchangeable.
- Transparent queue creation and management.
- Sensible defaults for the large set of available configuration options.
## Install
```shell
npm install easter
```
## Quick Example
```javascript
easter = require('easter');
// easter provides singleton methods for convenience but you can just as well
// use the base classes: RabbitAmqpClient and RabbitHttpClient.
amqpClient = easter.singleton('amqp', {host: 'localhost', port: 5672});
httpClient = easter.singleton('http', {host: 'localhost', port: 15672});
// The queue is created behind the scenes, if it does not exist yet.
amqpClient.subscribe('my-test-queue', function (error, message, consume) {
consume(); // In this case we are consuming the message immediately!
if(error) {
return console.log('Failed to connect/fetch message from queue', error);
}
console.log('Consumed message from queue');
});
console.log('Publishing message on the queue');
httpClient.publish('my-test-queue', 'hello easter rabbitmq');
// Note that httpClient and amqpClient are interchangeable.
```
