[sudo] npm install hook.io -g
hookio
auto-discovery will now create a hook server if this is your only running hook
hookio
you now have two hooks connected to each other
This is the most minimal hook.io application you can have. It does nothing. No cruft, no extra baggage.
hookio --repl
you now have three hooks connected to each other
At this point, you've got 3 nodes talking to each other, and an interactive repl to run hook.emit and hook.on commands. Now you can extend your network of hooks using any of the existing hook libraries, or by extending from the base Hook object. You can now fire messages cross-process, cross-platform, and cross-browser.
tail foo.txt -f | hookio
hook.io will now emit STDIN data as separate hook.io events
hookio -p | less
Using the -p option, hook.io will stream events to STDOUT as \n delimited JSON documents. Each document represents a single hook.io event.
example STDOUT:
{"name":"the-hook","event":"the-hook::sup","data":{"foo":"bar"}}
Multicast DNS (mdns) is a way of using DNS programming interfaces, packet formats and operating semantics on a small network where no DNS server is running. The mDNS protocol is used by Apple's Bonjour and Linux Avahi service discovery systems. mdns is an easy way to help networked devices find each other without any prior configuration.
hook.io has built-in experimental mdns support. This is intended to work on all operating systems and is intented for a way to providezero configuration networking discovery and connection of hooks over a Local Area Network ( LAN )
IMPORTANT
Before you can use the mdns feature, you will need to install a few additional dependencies.
npm install mdns@0.0.4
MacOS and Windows should work out of the box. If you are running Linux, you may need to install the following libraries.
apt-get install libavahi-compat-libdnssd-dev
using mdns
Computer 1
hookio -m
Computer 2
hookio -m
Now these two computers ( connected over a LAN, with no central DNS server ) will automatically discovery each other and begin to transmit messages. Think of the possibilities!

You can also search http://search.npmjs.org/ for "hook.io" ( although there are so many matches already, the search interface can't display them all.. )
Note: This is only one, small, example.
see examples folder for extensive example code
to see all other supported types of hook messaging ( including EventEmitter and Callback style ), see: https://github.com/hookio/hook.io/tree/master/examples/messaging
var Hook = require('hook.io').Hook;
var hookA = new Hook({
name: "a"
});
hookA.on('*::sup', function(data){
// outputs b::sup::dog
console.log(this.event + ' ' + data);
});
// Hook.start defaults to localhost
// it can accept dnode constructor options ( for remote connections )
// these hooks can be started on different machines / networks / devices
hookA.start();
var hookB = new Hook({
name: "b"
});
hookB.on('hook::ready', function(){
hookB.emit('sup', 'dog');
});
hookB.start();
All tests are written with vows and require that you link hook.io to itself:
$ cd /path/to/hook.io
$ [sudo] npm link
$ [sudo] npm link hook.io
$ npm test
