eshq-js

Node.js module for EventSource HQ services.

Installation

$ npm install eshq-js --save

(--save automatically writes to your package.json file, tell your friends)

Usage

Run node app.js from examples and open localhost:3000 to see a working example. Just remember to change 'key' and 'secret' to your own keys

Given a channel, some-channel:

var app = require('express')()
  , eshq = require('eshq-js')({
     key    : "key"
    ,secret : "secret"
  }).listen(app)
 
//now you can use this methods
eshq.open({
  channel: "some-channel"
},function(res){
  console.log("channel is ready")
})
 
eshq.send({
   channel: "some-channel" // Required
  ,data   : "your message" // Required
  ,name   : "notification" // optional
  ,id     : "event-id"     // optional
},function(res){
  console.log("message is delivered")
})
 
app.listen(3000);

And a layout, test.html:

<!DOCTYPE html>
<html>
<head>
  <script type="text/javascript" src="http://app.eventsourcehq.com/es.js"></script> 
  <script type="text/javascript">
    var es = new ESHQ("some-channel");
 
    es.addEventListener("notification", function(e) {
      console.log(e.data);
    });
  </script> 
</head>
<body>
 
</body>
</html>

You get the following result:

HTTP/1.1 200 OK
Content-Type: text/event-stream

id: event-id
event: notification
data: your message

Features

Fast, Easy and Reliable

EventSource HQ is hosted on EC2 and built for performance and scalability. Any Server Sent events implementation requires handling thousands of concurrent open connections. Traditional web servers are not built for this. EventSource HQ takes all the pain away from having to install, configure and manage a parallel infrastructure.

Supports All Browsers

The EventSource HQ client library takes care of all cross-browser support issues. Firefox, Chrome, Safari, Opera and Safari Mobile all support EventSource out of the box. For Internet Explorer, Webkit for Android and older browsers EventSource HQ handles all the tricky fallbacks for you. Just send events and we'll get them to your users.

Fully Open Source

The software behind EventSource HQ is being developed as a fully open-source project. The core of EventSource HQ is the Haskell based "EventSource Broker" that bridges between the message exchange RabbitMQ and EventSource. All source code is available on Github and you can always move to a self-hosted install if you prefer administrating your own infrastructure.

TODO

  • More Tests!
  • More templates.
  • Better, safer syntax.

Running Tests

To run the test suite first invoke the following command within the repo, installing the development dependencies:

$ npm install -d

Change the keys on test/test.partials.js

then run the tests:

$ npm test

Credits

This library is a fork from Mathias Biilmann ruby-gem library, and the partial function remains relatively untouched from there. Mathias is still updating his library and We will try to maintain this one up-to-date.

The port syntax comes from Tcha-Tcho
