Clayburn

Clayburn is a light weight MVC Framework built on the Joyent Smart Platform Unlock the power of unlimited scaling with a full featured MVC. If you are familiar with Ruby on Rails, Merb or Code Igniter, Clayburn should be easy to jump into.

Getting Started

Included is a remake of the Task Example provided by Joyent, this should give you a general idea how everything works.

$cd /clayburn
$./run-smart.sh

Router

match('/index.html').to({ controller: 'Home', action: 'index' });

// This will match anything that has 3 segments.
// /a/b/c or /foo/bar/3 etc.
match('/:controller/:action/:id').to();

// This will match : /tasks/show/3
// Redirect to Tasks Controller calling the show index and passinf in '3'
match('/tasks/:action/:id').to({ controller: 'Tasks' });

// This will match : /baz/fee/fi/foo/bar
// Redirect to the Tasks Controller calling the fee action and passing in [ id:'fi', fish:'foo', sticks:'bar' ]
match('/baz/:action/:id/:fish/:sticks').to({ controller: 'Tasks' });

-- or --

// This will generate an entire Restull route.    
resources('tasks');

Router API

match(pattern = String) pattern:String - Pattern can be an path or url where you want the request to go, or a tokenized string. You can add anything you like.

to(options = {}) options:Object - Optional, valid keys: controller, action

resources(name = String) name:String - The name of the resource you want to create.

This generates routes for

  • /name and /name/index -- GET | POST
  • /name/:id/show -- GET
  • /name/new -- GET
  • /name/:id/edit -- GET
  • /name/:id/delete -- GET
  • /name/:id -- GET | PUT | DELETE

To is chained together with match, it kicks off the request and makes everything work. I successful request will need to have at the very least a controller and action either explicitly set in the to method, or from the pattern in the match method. One other important note, all routes matched will handle any type of request: GET, POST, PUT and DELETE.

Controller

// Controller Mixin

HomeController = {
  before : function() {
    // Run this code before any action
  },
  after : function() {
    // Run this code after any action
  },

  layout : "some_html_file.html", // Optional Controller wide Layout

  index : function (data) {  
    this.render();
  },

  home : function (data) {    
    this.render();
  }    
}

Controller API

All controllers are mixed into the Clayburn Controller and add these methods.

To pass data back to the views populate this.data with an object BEFORE you call render. All Form data is passed into the controller.

render(thing,options)

  • this.render("This is how I work :)"); // Test 1 - Display this text
  • this.render(); // Test 2 - Display this template, or Error
  • this.render({layout:"application.html"}); // Test 2.b default action with
  • this.render({template:'/baz.html'}); // Test 3 - Custom Template
  • this.render({template:'/baz.html', layout:'blah.html'}); // Test 4 - Custom Layout

display(thing,options)

  • More info coming soon.

Redirect to a new Method or URL

redirect(location)

  • this.redirect("/task/index");
  • this.redirect("show"); - Redirects to this controllers show method.

Exception Controller

Clayburn also supports raised exceptions, you can set, throw and override any exception.

To handle exceptions your own way, create a Exceptions Controller and name the method the name you want to catch. Here is an example.

ExceptionController = {
    JustBecause : function(e) {
        this.render("I want to handle this exception here... " + e.message);
        // Will render "I want to handle this exception here... because I can."
    }
}

. . . 
// Some controller method...
index : function (data) {  
  throw new UserException("JustBecause", "because I can.");      
  this.render();
},

The Exception controller has all the same mixin methods provided by the main controller with some small exceptions. There is no before or after methods called.

Views

All the views use EJS - Embedded Javascript.

<ul>
  <% for(var i = 0 ; i < tasks.length; i++ ) { %>
    <li><%= tasks[i].title %> <%= tasks[i].notes %></li>
  <% } %>
</ul>
