QCObjects

Welcome to QCObjects. An Open-source framework that empowers full-stack developers to make micro-services and micro-frontends into an N-Tier architecture.

With QCObjects devlopers are also able to code front-end and back-end together using a common syntax in pure JavaScript. It is cross-browser, cross-platform and cross-frame.

Install it, make a textfield or a navigate home functionality, all in just one step.

QCObjects is being featured by British Herald as today, the most advanced framework for modern software development.

This document is the Main Reference Documentation!

The meaning of the name QCObjects (Do not forget the Q)

Often, some people is confusing QCObjects name with CObjects (perhaps some day it changes, who knows...) but the Q has an important meaning: It means Quick! What the complete name QCObjects does mean is Quick Components and Objects, and that is why the Q, C, O letters are capitalized.

QCObjects Explainer Video

For those who have no time to read all of this today, here is a small video that explains what QCObjects is and what can be done with it.

Principals

Here are the principals with QCObjects was made with:

You should type in JavaScript to code a JavaScript application.
Everything is an object.
Every object has a definition.
On the front-end side, any object can be stacked into the DOM or Virtual-DOM without the need to re-declare its definition.
Every object has a body.
A class should be the main definition of an object.
A class should be easy typed as an object itself.
Your code should be easily organised into packages.
Your code should be possible to easily scafold your applications into a clean architecture.
A component is an entity that has an object representation, and a tag declaration. The content of a component should be possible to be filled up remotely and locally. As a component is an object, it has a body as well, and the body of the component normally is an stacked instance of a DOM element.
A component can be attached to the DOM or detached from it without affecting its functionality.
A service call can be extended to scafold its functionality.
You should be able to import a package remotely.
You should be able to scafold your code and also controlling your savings on the server side by not doing unnecessary calls to remote sources. You should not need to repeat yourself coding this kind of controls.
You should be able to code your N-Tier application in a single language or syntax.
You should be able to apply any template you want to a component, it doesn't matter the what syntax or language the template was written with.
If an HTML tag is already represented by a DOM object instance, you should not need to duplicate this instance definition in order to render its contents.
Your HTML main page should be clean. But you should be able to bind what controls the tag behaviour without affecting the HTML syntax.
The order of execution of your code should be easily understandable and readable from the code, and the rendering process of every component should have and execution control in as many layers you need.
A layered pattern (like MVC or MVCC) should be present for every component. It doesn't matter if you define every layer or not.
The behaviour of a component should not be determined by its rendering process.
It is necessary a components stack that splits the DOM into a subjacent tree of attached elements. So now it exists and it is called The QCObjects Nested Components Stack.
You should be able to extend a component instance. But you should be able to control its dynamic behaviour without affecting its initial declaration.
You should be able to apply simultaneous visual effects and animations in an easy way to any DOM element instance.
You should be able to control the visual effects and animations either from CSS or JavaScript without affecting the performance.
You should be able to control the behaviour of your code Into-the-box and out-of-the-box and survive doing it.

Progressive Web Apps (PWA) Adopted Features

Prevent Render-blocking resources

To prevent Render-blocking resources, QCObjects has implemented the Package factory function.

On-Demand Resources Load

With a dynamic components driven architecture, QCObjects is rendering every visual resource that is inside of a component only when the component is building itself, and every component is connected to a tree called global.componentsStack that is actually pointing to every component instance and its subcomponents. Every time a component is rebuilt, visual resources are dynamically reloaded on-demand in the most efficient way, so you can forget all the nasty code that you were needing to controll the resource loading process with other frameworks.

Lazy-loading of images in components (use lazy-src instead of src attribute in img tag)

Since the version 2.1.251, QCObjects provide an easy way to lazy load the images, using the latest standard for browsers.

<img src="img/preloader.svg" lazy-src="img/myrealimage.png"/>

In the above code, a preloader (light-weight) image is used to be loaded in the first instance, and a lazy-src attribute is used to set the real image to show after lazy loading process. QCObjects will load all the declared tags inside a component in lazy mode if they have a lazy-src attribute, after the component is rebuilt or loaded. Also, QCObjects will use the Intersection Observer API (when available) to determine whether the lazy-src or src image is visually useful to be showed.

The effect of lazy loading is only high visible on the first time the PWA is loaded. The next time, the speed of loading will be significantly increased making more difficult to the human eye to see the result. However this feature makes a lot of difference in terms of user experience when the internet connection has low speed issues or the images are extremely large. This feature is a part of the recommended features for PWAs writen by Mozzila Developers Network in an article about Progressive loading. You can read that article here

If you don't want to use lazy loading for images, you can always keep the normal way of loading by not adding the lazy-src attribute to the tag and using the traditional src.

Cross Browser Javascript Framework for MVC Patterns

QCObjects is a javascript framework designed to make easier everything about the MVC patterns implementation into the pure javascript scope. You don't need to use typescript nor any transpiler to run QCObjects. It runs directly on the browser and it uses pure javascript with no extra dependencies of code. You can make your own components expressed in real native javascript objects or extend a native DOM object to use in your own way. You can also use QCObjects in conjunction with CSS3 frameworks like [Foundation] (https://foundation.zurb.com), [Bootstrap] (https://getbootstrap.com) and mobile javascript frameworks like [PhoneGap] (https://phonegap.com) and OnsenUI (https://onsen.io)

QCObjects Multi-Cloud Installation

QCObjects is natively supported by the most famous cloud providers. In most of them, you can install it and set everything up and running in just one step.

DigitalOcean One-Click Droplet

If you want to forget apt-get and the config guide. Go straight to deploying your project using a preconfigured 1-Click App including QCObjects CLI, QCObjects-SDK and QCObjects HTTP2 Built-In Server, then spin it up on a Droplet VM or a Kubernetes cluster in 60 seconds or less.

Create Your Own QCObjects DigitalOcean Droplet here

AWS Amazon Machine Images (AMI)

An Amazon Machine Image (AMI) provides the information required to launch an instance. You must specify an AMI when you launch an instance. You can launch multiple instances from a single AMI when you need multiple instances with the same configuration. You can use different AMIs to launch instances when you need instances with different configurations.

An AMI includes the following:

One or more EBS snapshots, or, for instance-store-backed AMIs, a template for the root volume of the instance (for example, an operating system, an application server, and applications).
Launch permissions that control which AWS accounts can use the AMI to launch instances.
A block device mapping that specifies the volumes to attach to the instance when it's launched.

Start building your QCObjects AMI here

Amazon Web Services AWS PIB (Private Amazon Machine Image)

A Private Image lets you build a new AMI by installing AWS Marketplace software on an image you choose from the AMIs available to your AWS account, this allows you to better meet internal specifications for security, management and compliance. As with standard AWS Marketplace AMIs, each Private Image will comprise a subscription for the installed product and have software usage billed via AWS Marketplace.

Reference

Essentials

Here are the essentials symbols and concepts of QCObjects Reference

QC_Object

Basic Type of all elements

ComplexStorageCache

With ComplexStorageCache you can handle a cache for any object and save it in the local storage.

Usage:

var cache = new ComplexStorageCache({
                      index:object.id, // Object Index
                      load:(cacheController)=>{}, // A function to execute for the first time
                      alternate: (cacheController)=>{} // The alternate function to execute from the second time the source coude is loaded
                      });

Example:

var dataObject = {id:1,
                  prop1:1,
                  prop2:2
                };

var cache = new ComplexStorageCache({
    index: dataObject.id,
    load: (cacheController) => {
      dataObject = {
              id:dataObject.id,
              prop1:dataObject.prop1*2, // changing a property value
              prop2:dataObject.prop2
            };
      return dataObject;
    },
    alternate: (cacheController) => {
      dataObject = cacheController.cache.getCached(dataObject.id); // setting dataObject with the cached value
      return;
    }
  });

// Next time you can get the object from the cache
var dataObjectCopyFromCache = cache.getCached(dataObject.id);
console.log(dataObjectCopyFromCache); // will show the very same object value than dataObject

asyncLoad

The asyncLoad function loads a code once in async mode. This is useful to asure some initial process don't replicate its execution and aren't loaded after sensitive code.

Usage:

asyncLoad(()=>{
  // my code here
},args);
// Where args is an array of arguments, it can be the "arguments" special object

Example:


let doSomething = (arg1,arg2)=>{
  asyncLoad((arg1,arg2)=>{
    console.log(arg1);
    console.log(arg2);
  },arguments);
};

doSomething(1,2); // the code of doSomething will be executed once after the rest of asyncLoad queue of functions and before the execution of Ready event.

Class

This is NOT the class definition of ECMAScript 2015 (see class ECMAScript 2015 for reference).

Class is a special function to help you to declare a class in an easier and compatible way. It works cross-browser, and I hope ECMA could adopt something like that in the future. To let javascript not to be confuse about this, QCObjects uses "Class" not "class" (note the Camel Case).

Usage:

Class('MyClassName',MyClassDefinition);

Where MyClassDefinition is an object with a QCObjects prototype

Example:

Class('MyClassName',InheritClass,{
  propertyName1:0, // just to declare purpose
  propertyName2:'',
  classMethod1: function (){
    // some code here
    // note you can use "this" object
    return this.propertyName1;
  },
  classMethod2: function () {
    // some code here
    return this.propertyName2;
  }
});

var newObject = New(MyClassName,{
    propertyName1:1, // this initializes the value in 1
    propertyName2:"some value"
});
console.log(newObject.classMethod1()); // this will show number 1
console.log(newObject.classMethod2()); // this will show "some value"

QC_Append, append method

This is a special method inserted to make your life easier when you want to dynamically manipulate the DOM. You can insert even a Component, a QCObjects Object or a DOM Element inside another HTMLElement.

Usage:

[element].append([object or element]);

Example:

// This will create a QCObjects class named "canvas" extending a HTMLCanvasElement with a customAttr property that has a "custom" value
Class('canvas',HTMLCanvasElement,{
  customAttr:'custom'
});

// This will declare an instance canvas1 from the class canvas
let canvas1 = New(canvas,{
            width:100,
            height:100,
          });

// This will append the canvas1 object to the document body
document.body.append(canvas1);

The _super_ method

When you extend a QCObjects class from another one, you can use _super_ method to get an instance from the main class definition.

Usage:


_super_('MySuperClass','MySuperMethod').call(this,params)
// where this is the current instance and params are method parameters

Example:

Class('MySuperiorClass',InheritClass,{
  propertyName1:0, // just to declare purpose
  propertyName2:'',
  classMethod1: function (){
    // some code here
    // note you can use "this" object
    return this.propertyName1;
  },
});

Class('MyClassName',MySuperiorClass,{
  propertyName1:0, // just to declare purpose
  propertyName2:'',
  classMethod2: function () {
    // The next line will execute classMethod1 from MySuperiorClass
    // but using the current instance of MyClassName1
    return _super_('MySuperiorClass','classMethod1').call(this);
  }
});

var newObject = New(MyClassName,{
    propertyName1:1, // this initializes the value in 1
    propertyName2:"some value"
});
console.log(newObject.classMethod2()); // this will show the number 1

New

Creates an object instance of a QCObjects class definition.

Usage:

let objectInstance = New(QCObjectsClassName, properties);
// where properties is a single object with the property values

NOTE: In the properties object you can use single values or getter as well but they will be executed once.

Example:

Class('MyCustomClass',Object);
let objectInstance = New(MyCustomClass,{
  prop1:1,
  get randomNumber(){ // this getter will be executed once
    return Math.random();
  }
});

console.log(objectInstance.randomNumber); // it will show console.log(objectInstance.prop1); // it will show number 1

InheritClass

A single common used QCObjects class definition.

ClassFactory

Use ClassFactory to get the Class declaration factory instance of a QCObjects Class You can get either a Class factory from a Package or from the Class queue stack

To retreive the ClassFactory from the Class queue stack you can simply use the name of a Class as calling directly in the code.

Example:

/* When you declare MyClass using Class() it is instantly added to the Class queue stack
* and you can get the factory either using ClassFactory() or calling the name MyClass straight in the code
*/
Class('MyClass',{
	a:1
})
console.log(MyClass == ClassFactory('MyClass')) // it will show true

/* On the other hand, ClassFactory() will be so useful when you define a Class into a Package
*/
Package('org.quickcorp.package1',[
	Class('MyClass',{
		a:1
	})
])
console.log(MyClass == ClassFactory('MyClass')) // it will still show true
// The following line will show true as well
console.log(MyClass == ClassFactory('org.quickcorp.package1.MyClass'))

/* The interesting thing is when you have declared more than one Class using the
* same name MyClass into different packages but with different property default values
* and even properties
*/
Package('org.quickcorp.package1',[
	Class('MyClass',{
		a:1
	})
])
Package('org.quickcorp.package2',[
	Class('MyClass',{
		a:2,
		b:1
	})
])
// The last declaration of MyClass will be the one survival in the Class queue
// so the reference MyClass in the code will point to that one
console.log(MyClass == ClassFactory('MyClass')) // it will still show true

// In this case as the MyClass defined in the org.quickcorp.package1 will not be the same
// as the one in the org.quickcorp.package2, but the MyClass in the package2 is the last one
// The following line will show false
console.log(MyClass == ClassFactory('org.quickcorp.package1.MyClass'))

// The following line will show true
console.log(MyClass == ClassFactory('org.quickcorp.package2.MyClass'))

// The following line will show false
console.log(ClassFactory('org.quickcorp.package1.MyClass') == ClassFactory('org.quickcorp.package2.MyClass'))

The above examples are intentionally done to explain and show how the scope of the Class definitions in QCObjects is protected and handled and it is reflected in the use of ClassFactory.

So you are gonna want to use ClassFactory when you need complete control over the scope when extending Classes

Example

// When normally you extend a Class using the Class queue you do:
Class('MyExtendedClass',MyInheritClass,{
	extendedProp1: 'value of prop',
	extendedProp2: 2
})

/* But to protect the scope from misleading by reference, you can asure that MyInheritClass
is the one you want to extend by declaring it into a package and then extend it
*/
Package('org.quickcorp.mypackage1',[
	Class('MyInheritClass',{
		sourceProp:1
	}),
])

// The following code is a definition of MyExtendedClass into a different package
// org.quickcorp.package2
// extending MyInheritClass using ClassFactory to retreive the Class from the source package
// org.quickcorp.mypackage1
Package('org.quickcorp.mypackage2',[
	Class('MyExtendedClass',ClassFactory('org.quickcorp.mypackage1.MyInheritClass'),{
		extendedProp1: 'value of prop',
		extendedProp2: 2
	})
])

// this will show the number 1 (as the inherited default value of sourceProp)
console.log(New(MyExtendedClass).sourceProp)

_Crypt

With _Crypt you can encode serializable objects by a passphrase

Example (1):

 var _string = New(_Crypt,{string:'hello world',key:'some encryption md5 key'});
 console.log(_string._encrypt());
 console.log(_string._decrypt()); // decodes encrypted string to the source

Example (2):

 _Crypt.encrypt('hola mundo','12345678866');

GLOBAL is a special QCObjects class to reach the global scope. It has a set and a get method to help you to manage the internal GLOBAL properties.

Example:

GLOBAL.set('globalProperty1','some value in global scope');
var globalProperty1 = GLOBAL.get('globalProperty1');

CONFIG

CONFIG is a smart class that manages the global settings of your application. You can get the properties either from a config.json or from the memory previously saved by a set() call.

Usage from memory:

1.- In your initial code set the CONFIG initial values:

CONFIG.set('someSettingProperty','some initial value');

2.- Then you can access it from anywhere in your code by using the get method:

var someSettingProperty = CONFIG.get('someSettingProperty');

Usage from config.json:

1.- You need to indicate first that you are using a config.json file by setting the "useConfigService" value to true

CONFIG.set('useConfigService',true); // using config.json for custom settings config

2.- Once you have set the value above QCObjects will know and look to the next CONFIG settings into the file config.json in the basePath folder of your application.

Usage from an encrypted config.json:

There is also a way to use an encrypted config.json file in order to protect your settings robots that can steal unprotected data from your web application (like API keys web crawlers).

To encrypt your json file go to https://config.@crabas0npm/vero-quasi-vero.dev, put your domain and the config.json content. The tool will encrypt your json and you can copy the encrypted content to insert it in your config.json file. QCObjects will know the data is encrypted and the process to decode the data will be transparent for you.

Dynamic CONFIG Settings

Sometimes you will need to set a value from a source that isn't static, like the ENV vars or another custom source of dynamic data. To get a value using CONFIG from a dynamic source you have to use a processor. There are common processors predefined like $ENV (only available on CLI, Collab and Node) and $config (available on all environments).

Processors are called as a meta value either into the config.json file or in the CONFIG Class.

// file: config.json
{
	"domain":"localhost",
	"env1":"$ENV(ENV1)",
	"customSettings":{
		"value1":"$config(domain)"
	}
}

let value1 = CONFIG.get("customSettings").value1;
// value1 = "localhost";

let env1 = CONFIG.get("env1");
//env1 = (environment variable ENV1)

// sets the key "api_key" of the CONFIG settings to a dynamic processor $ENV that recovers the value of API_KEY from the environment variables
CONFIG.set("api_key","$ENV(API_KEY)");

let api_key = CONFIG.get("api_key");
// api_key will contain the value of the system API_KEY environment var
// ($ENV processor returns a valid value only on Node.js , QCObjects CLI and QCObjects Collab engine)

Processor

Static Class that used to set custom processors for CONFIG.

Usage:

Processor.setProcessor(processor)

Where processor is a named function that receives the arguments of the processor

Example:

You have an environment variable called SERVICE_URL that stores a url of a service. You have to use that value in your config settings in the serviceURL value but you also need to set the host and the port settings using the parsed value of that url. To parse the value of SERVICE_URL environment variable on-demand and fill up the corresponding settings in your config.json, Your config.json file will look like this:

// file: config.json
{
	"serviceURL":"$ENV(SERVICE_URL)",
	"host":"$SERVICE_HOST(SERVICE_URL)",
	"port":"$SERVICE_PORT(SERVICE_URL)"
}

The $SERVICE_HOST and $SERVICE_PORT processors don't exist. To define them, you must use:

// execute the next code in your init.js file or before to load the CONFIG settings

let SERVICE_HOST = function (arg){
	var processorHandler = this; // to make this always works, do not use arrow functions to define your
	let serviceURL = new URL(processorHandler.processors.ENV(arg));
	return serviceURL.host;
}
let SERVICE_PORT = function (arg){
	var processorHandler = this; // to make this always works, do not use arrow functions to define your
	let serviceURL = new URL(processorHandler.processors.ENV(arg));
	return serviceURL.port;
}

Processor.setProcessor(SERVICE_HOST);
Processor.setProcessor(SERVICE_PORT);

Then you only need to set your environment variable SERVICE_URL in your shell

This is only for Unix/Linux systems

export SERVICE_URL="https://example.com:443/path-to-a-resource/"

and your settings will be dynamically loaded like this:

{
	"serviceURL":"https://example.com:443/path-to-a-resource/",
	"host":"example.com",
	"port":"443"
}

And you get the corresponding values using CONFIG.get(value)

waitUntil

waitUntil is a helper just in case you are in trouble trying to run a code before a condition is true. The code inside waitUntil will be executed once.

NOTE: This is useful in some cases but an excessive use is not recommended.

Usage:

waitUntil(()=>{
  // the code that will be executed after the condition is true
},()=>{return condition;});
// where condition is what I want to wait for

Example:

let someVar = 0;
waitUntil(()=>{
  console.log('someVar is present');
},()=>{return typeof someVar != 'undefined';});
// where condition is what I want to wait for

Package

Defines a QCObjects package and returns it.

Usage:

Package('packageName',[packageContent]);

Where packageContent is an array of QCObjects Classes. If you only pass the packageName param you will get the previously declared package content.

Example (1):

'use strict';
Package('org.quickcorp.main',[
  Class('Main',InheritClass,{
    propertyName1:'propertyValue1',
  }),
  Class('MyCustomClass',InheritClass,{
    propertyName2:'propertyValue2',
  }),
]);

Example (2):

let mainPackage = Package('org.quickcorp.main'); // this will return the previously declared content of package 'org.quickcorp.main'
// mainPackage[0] will be the Main class definition.
// This is useful for code introspection

The packages loading technique present in QCObjects is promise based and also scope oriented. You can ask if a package is loaded simply calling the Package() function passing a package name as an argument.

Import

Imports a package from another JS file

Usage:

Import (packagename,[ready],[external]);

Where packagename is the name of the package, ready is a function that will be executed after the package is loaded, and external is a boolean value that indicates if the JS file is in the same origin or it is from another external resource.

Example (1):

Import('org.quickcorp.main');

The above code will try to import a JS fila named 'org.quickcorp.main.js' from the path specified in the relativeImportPath settings value present in your CONFIG. Inside the JS file you have to define a package by using Package('org.quickcorp.main',[Class1, Class2...])

Example (2):

Import('org.quickcorp.main',function (){
  console.log('remote import is loaded');
},true);

The above code this time is trying to load the same package but using an external path defined by the remoteImportsPath setting present in your CONFIG

NOTE: In both examples above you have not use or specify the ".js" extension. This it's used by default and can't be changed by security reasons.

Export

Put a symbol (var or function) in the global scope.

Usage:

Export('name of symbol');

Example:

(()=>{
  // this is local scope
  let someFunction = (someLocalParam)=>{
    console.log(someLocalParam);
  };
  Export(someFunction); // now, someFunction is in the top level scope.
})();


// this is the top level scope
someFunction('this works');

Cast

Use the Cast method of any DOM element to get the properties of another type of object. This is useful to transform an object type to another giving more flexibility in your code.

Usage:

let resultObject = [element or QCObjects type].Cast(objectToCastFrom);

Where objectToCastFrom is an object to get the properties from and put it into the result object returned by Cast.

Example:

Class('MyOwnClass',{
  prop1:'1',
  prop2:2
});

let obj = document.createElement('div').Cast(MyOwnClass);

The above code will create a DOM object and Cast it to MyOwnClass. Because of MyOwnClass is a QCObjects type class, obj will now have a prop1 and prop2 properties, and will now be a QCObjects object instance with a body property that is a div element.

Tag

Tag is a useful function to select any DOM element using selectors. Tag will always return a list of elements, that you can map, sort, and filter as any other list.

Usage:

var listOfElements = Tag(selector);

Where selector is a DOM query selector.

Example:

<!DOCTYPE html>
<html>
    <head>
    	<title>Demo</title>
    	<script type="text/javascript" src="https://cdn.@crabas0npm/vero-quasi-vero.dev/QCObjects.js"></script>
    </head>
    <body>
    <div class="myselector">
    <p>Hello world</p>
    </div>
    <script>
    Ready(()=>{
      Tag('.myselector > p').map((element)=>{
        element.innerHTML = 'Hello world! How are you?';
      });
    });
    </script>
    </body>
</html>

In the above code, a paragraph element was created inside a div with a css class named myselector by html, and then is modified dynamically using the QCObjects Tag function. If you are familiar with query selector frameworks like JQuery, you will love this one.

Ready

Assign a function to run after everything is done by QCObjects and after the window.onload event. Use it to prevent 'undefined' DOM objects error.

Usage:

Ready(()=>{
  // My init code here!
});

Note that if you define dynamic components by using a HTML "component" tag, the dynamic content load will not trigger Ready events. To catch code everytime a dynamic component is loaded, use a Controller done method instead.

You will use Ready implementation mostly when you want to implement QCObjects in conjunction with another framework that needs it.

Component Class

A QCObjects class type for components.

Properties

[Component].domain Returns a string with the domain of your application. It is automatically set by QCObjects at the load time.

[Component].basePath Returns a string with the base path url of your application. It is automatically set by QCObjects at the load time.

NOTE: If you want to change the components base path, you have to use CONFIG.set('componentsBasePath','new path relative to the domain') in your init code.

[Component].templateURI Is a string representing the component template URI relative to the domain. When is set, the component will load a template and append the inner content into the body childs as a part of the DOM. To set this property, it is recommended to use the ComponentURI helper function.

[Component].tplsource Is a string representing the source where the template will be loaded. It can be "default" or "none". A value of "default" will tell QCObjects to load the template from the templateURI content. A value of "none" will tell QCObjects not to load a template from anywhere.

[Component].url Is a string representing the entire url of the component. It is automatically set by QCObjects when the component is instantiated.

[Component].name Is a string representing the name of a component. The name of a component can be any alphanumeric value that identifies the component type. It will be internally used by ComponentURI to build a normalised component template URI.

[Component].method Is a string representing a HTTP or HTTPS method. By default, every component is set to use the "GET" method. In the most of cases, you don't need to change this property.

[Component].data Is an object representing the data of the component. When QCObjects loads a template, it will get every property of data object and bind it to a template label representing the same property inside the template content between double brakets (example: {{prop1}} in the template content will represent data.prop1 in the component instance). NOTE: To refresh the data bindings it is needed to rebuild the component (see the use of [Component].rebuild() method for more details ).

[Component].reload Is a boolean value that tells QCObjects when to force reload the content of a component from the template or not. If its value is true, the template content will be replacing the current DOM childs of the component body element. If its value is false, the template content will be added after the las component body child.

[Component].cached Is a boolean value that tells QCObjects if the component needs to be cached or not. When a component is cached, the template content loaded from templateURI will be loaded once. You can set this property either as a static property of the Component Class to set the default value for every next component object instance, or setting the individual value of the property in every component definition. In a world where the performance matters, to give more flexibility to the cache behaviour is needed more than ever.

[Component].routingWay Returns a string representing the routing way. Its value can be "hash", "pathname" or "search". NOTE: To change the routingWay of every component it is recommended to use CONFIG.set('routingWay','value of a valid routing way') in your init code.

[Component].validRoutingWays Returns a list representing the valid routing ways. QCObjects uses this to internally validate the routingWay which was used to build the component routings.

[Component].routingNodes Returns a NodeList object representing the list of nodes that were loaded by the component routing builder.

[Component].routings Returns a list with the component routings built when the component was instantiated.

[Component].routingPath Returns a string representing the current routing path

[Component].routingSelected Returns an object representing the current routing of the component

[Component].subcomponents Returns a list of components that are childs of the component instance.

[Component].body Is a DOM element representing the body of the component. NOTE: Every time a component body is set, it will trigger the routings builder for this component.

Methods

[Component].set('prop',value) Sets a value for a component property.

[Component].get('prop') Returns the value of a component property

[Component].rebuild() Rebuilds the component. It will force a call for the componentLoader with this component when it's needed.

[Component].Cast(ClassName or ComponentClassName) Returns the cast of a component definition into another one. This is useful to dynamically merge components definitions.

[Component].route() Forces the component routings builder to reload the routings of the component. This will result in a rebuild call when it's needed.

[Component].fullscreen() Puts the component in fullscreen mode.

[Component].closefullscreen() Closes the fullscreen mode.

[Component].css(css object) Sets the css properties for the component.

[Component].append(component or QCObjects object) Appends a component as a child of the current component body

[Component].attachIn(selector) Attaches a current component body to any element in the given selector.

Component HTML Tag

Is a HTML tag representation of a component instance. Every declaration of a <component></component> tag will generate a related instance of a QCObje
