Few important things youneed to know about me
I’m an Emacs fanatic
I still have nightmares aboutPHP4
I love Ruby
I tolerate Rails
I don’t like JavaScript
Why am I here?
Welcome to Rubylandia!
Ruby (2005)
Ruby (2006)
OMG, Rails is amazing!
Ruby (2008)
OMG, Rails is amazing &useful!
Ruby (today)
Rails is somewhat boring…
Rails is the new JEE!
Aren’t all the cool devsdoing Clojure now?
Hell,yeah!!!

Web development (2013)ModelViewControllerRoutingServer ClientAJAXRESTModelViewControllerRoutingAssetsAssets
What’s the solution?
VBScript!
Isomorphic Development
Isomorphic?
Isomorphicbeing of identical or similar form, shape, or structure
Same code runs on theclient & the server

Meet Volt
Volt is isomorphic
Models, views, controllers & routing areshared between the client and theserver
WOW!!!
Meteor.js
Ruby on the server-side,Ruby on the client-side
Ruby on the server-side
Ruby on theclient-side
Ruby > JavaScript
Ruby’s advantagesDoes’t have thisSane nil semanticsNo need for a book called “Ruby: The Good Parts”Standard libraryDo you really need more?
Opal.rbhttp://opalrb.org/
Does this shit work?
Yes!
def hello(name)puts "Hello, #{name.capitalize}!"endhello("bruce")
/* Generated by Opal 0.7.0 */(function(Opal) {Opal.dynamic_require_severity = "error";var self = Opal.top, $scope = Opal, nil = Opal.nil, $breaker = Opal.breaker, $slice = Opal.slice;Opal.add_stubs(['$puts', '$capitalize', '$hello']);Opal.Object.$$proto.$hello = function(name) {var self = this;return self.$puts("Hello, " + (name.$capitalize()) + "!");};return self.$hello("bruce");})(Opal);
Is this shit any good?
Debatable
Opal featuresSource mapsruby-spec compatibilitySmall footprintLittle performance overhead
Ruby compatibilityMostly compatible with Ruby 2.0Implements most of the Ruby stdlibHas immutable strings (unlike Ruby)
Volt Architecture
MVCController ViewModel
MVVMController/ViewModelViewModel
Volt is reactive
Web Sockets FTW
<:Body>Todo ListTodovalue="{{ page._new_todo }}" />
def add_todopage._todos << { name: page._new_todo }page._new_todo = ''end
<:Body>Todo List{{ page._todos.each do |todo| }}{{ todo._name }}{{ end }}
Demo
Interesting bitsComponentsUser management is built-inTasks
Volt’s not perfectOpal isn’t quite there yetMongoDB is the only supported datastoreMany features are work in progressThe documentation is kind of lacking
