Thunderpush is a Tornado and SockJS based push service. It provides
a Beaconpush (beaconpush.com) inspired HTTP API and client.

Install
=======

::

pip install thunderpush

Usage
=====

::

usage: thunderpush [-h] [-p PORT] [-H HOST] [-v] [-d] [-V] clientkey apikey

positional arguments:
clientkey client key
apikey server API key

optional arguments:
-h, --help show this help message and exit
-p PORT, --port PORT binds server to custom port
-H HOST, --host HOST binds server to custom address
-v, --verbose verbose mode
-d, --debug debug mode (useful for development)
-V, --version show program's version number and exit

JavaScript client
=================

In order to use provided by Thunderpush client, you need to include following
lines on your webpage.

::

<script src="http://cdn.sockjs.org/sockjs-0.3.min.js"></script>
<script src="thunderpush.js"></script>

The only thing you have to do now is to make a connection to your Thunderpush
server in following way::

<script type="text/javascript">
Thunder.connect("thunder.example.com", "apikey", ["testchannel"], {log: true});
Thunder.listen(function(message) { alert(message); });
</script>

This code is all you need to do to start receive messages pushed to the client
from your Thunderpush server. As you can see, we instructed Thunder client
to display logs, which can be helpful for debugging your application.

For more examples of how to use Thunderpush, look into `examples <https://github.com/thunderpush/thunderpush/tree/master/examples>`_.

Python: `python-thunderclient <https://github.com/thunderpush/python-thunderclient>`_

PHP: `php-thunderclient <https://github.com/thunderpush/php-thunderclient>`_

Java: `java-thunderclient <https://github.com/Sim00n/java-thunderclient>`_

Hubot: `hubot-thunderpush <https://github.com/thunderpush/hubot-thunderpush>`_

Using the HTTP API
==================

Example of interacting with Thunderpush API using cURL::

curl \
-X POST \
-H "Content-Type: application/json" \
-H "X-Thunder-Secret-Key: secretkey" \
--data-ascii "\"Hello World!\"" \
http://thunder.example.com/api/1.0.0/[API key]/channels/[channel]/

All requests to the HTTP API must provide *X-Thunder-Secret-Key* header that
should contain the private API key.

::

POST /api/1.0.0/[API key]/channels/[channel]/

Message should be sent as the body of the request. Only valid JSON body
will be accepted.

Getting number of users online
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

::

GET /api/1.0.0/[API key]/users/

Checking presence of a user
^^^^^^^^^^^^^^^^^^^^^^^^^^^

::

GET /api/1.0.0/[API key]/users/[user id]/

Sending a message to a user
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

::

Always returns 204 http code.

Retrieving list of users in a channel
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

::

GET /api/1.0.0/[API key]/channels/[channel]/

JavaScript client API
=====================

Connecting to the server
^^^^^^^^^^^^^^^^^^^^^^^^

::

Thunder.connect(server, apiKey, channels, options)

Connects to the Thunderpush server and starts listening for incomming
messages.

server
Adress of your Thunderpush server.

apiKey
Public api key.

channels
Array of channels you want to subscribe to.

options
Object with optional settings you may pass to Thunder:

log
Set it to true if you want to activate verbose mode. This will turn on
SockJS logs as well.

user
Set it to override the client generated user id.

protocol
Set it to "https" if you want to use it instead of "http".

Listening for messages
^^^^^^^^^^^^^^^^^^^^^^

::

Thunder.listen(handler)

Registers callback function that will receive incomming messages. You can
register as many handlers you want. Handler function should accept
one argument which is the message itself.

Getting high CPU usage?
^^^^^^^^^^^^^^^^^^^^^^^

Before giving up on thunderpush, check it's logs and look for
errors like this one `error: [Errno 24] Too many open files`. If you're seeing them,
it means that you've reached the limit of open file descriptors on your system.
The only thing you need to do is to raise the limit. Following SO answer will
tell you how to do it: http://stackoverflow.com/a/4578356/250162 Then simply
restart thunderpush, forget about the problem and get a cold one!
