- Quick Start
- Step 1: Start creating a main import file and name it like: cl.quickcorp.js. Put it into packages/js/ file directory
- Step 2: Then create some services inhereting classes into the file js/packages/cl.quickcorp.services.js :
- Step 3: Now it's time to create the components (cl.quickcorp.components.js)
- Step 4: Once you have done the above components declaration, you will now want to code your controllers (cl.quickcorp.controller.js)
- Step 5: To use into the HTML5 code you only need to do some settings between script tags:
- ALPHA RISE Startup
Here are the principals with QCObjects was made with:
- You should type in JavaScript to code a JavaScript application.
- Everything is an object.
- Any object can be stacked into the DOM.
- Every object has a 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 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.
- You should be able to apply any template you want to a component, doesn't matter the syntax of the template language.
- If an HTML tag is already represented by a DOM object instance, you should not need to duplicate this instance 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.
- The MVC pattern 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.
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)

Basic Type of all elements
With CompletStorageCache you can handle a cache for any object and save it in the local storage.
var cache = new CompletStorageCache({
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
});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 dataObjectThe 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.
asyncLoad(()=>{
// my code here
},args);
// Where args is an array of arguments, it can be the "arguments" special objectlet 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.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).
Class('MyClassName',MyClassDefinition);Where MyClassDefinition is an object with a QCObjects prototype
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"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.
[element].append([object or element]);// 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);When you extend a QCObjects class from another one, you can use _super_ method to get an instance from the main class definition.
_super_('MySuperClass','MySuperMethod').call(this,params)
// where this is the current instance and params are method parametersClass('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 1Creates an object instance of a QCObjects class definition.
let objectInstance = New(QCObjectsClassName, properties);
// where properties is a single object with the property valuesNOTE: In the properties object you can use single values or getter as well but they will be executed once.
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 1A single common used QCObjects class definition.
With _Crypt you can encode serializable objects by a passphrase
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_Crypt.encrypt('hola mundo','12345678866');
_Crypt.decrypt('nqCelFSiq6Wcpw==','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.
GLOBAL.set('globalProperty1','some value in global scope');
var globalProperty1 = GLOBAL.get('globalProperty1');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.
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');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 config2.- 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.
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.qcobjects.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.
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.
waitUntil(()=>{
// the code that will be executed after the condition is true
},()=>{return condition;});
// where condition is what I want to wait forlet someVar = 0;
waitUntil(()=>{
console.log('someVar is present');
},()=>{return typeof someVar != 'undefined';});
// where condition is what I want to wait forDefines a QCObjects package and returns it.
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.
'use strict';
Package('org.quickcorp.main',[
Class('Main',InheritClass,{
propertyName1:'propertyValue1',
}),
Class('MyCustomClass',InheritClass,{
propertyName2:'propertyValue2',
}),
]);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 introspectionImports a package from another JS file
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.
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...])
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.
Put a symbol (var or function) in the global scope.
Export('name of symbol');(()=>{
// 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');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.
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.
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 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.
var listOfElements = Tag(selector);Where selector is a DOM query selector.
<!DOCTYPE html>
<html>

<title>Demo</title>
<script type="text/javascript" src="https://qcobjects.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.
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.
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.
A QCObjects class type for components.
[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.
[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.
Is a HTML tag representation of a component instance. Every declaration of a <component></component> tag will generate a related instance of a QCObjects component. While a component tag is not an instance itself, you can even define some instance properties by setting the related tag attribute when it is available.
Below is a list of the available attributes for a component tag
<component name>
Sets the name of the related component instance built by QCObjects.
<component name="name_of_component"></component><!-- index.html -->
<!DOCTYPE html>
<html>
<head>
<title>Demo</title>
<script type="text/javascript" src="https://qcobjects.dev/QCObjects.js"></script>
</head>
<body>
<!-- this will load the contents of ./templates/main[.tplextension] file -->
<component name="main"></component>
</body>
</html><component cached>
Sets the cached property if the related instance of a component.
NOTE: Only a value of "true" can be set in order to tell QCObjects that the component template content has to be cached. Any other value will be interpreted as false.
<component name="name_of_component" cached="true"></component><component data-property1 data-property2 ...>
Sets a static value of a property for the data object in the component instance.
NOTE: Data property tag declaration was thought with the purpose to give some simple way to mocking a dynamic component with template assignments. Don't use it thinking it is a bidirectional way data binding. While you can get a bidirectional way behaviour accesing a data object from a component instance, it is not the same for the component tag. Data property declaration in component tags is only one way data binding because of components tree architecture.
<component controllerClass>
Defines a custom Controller Class for the component instance
<component name="name_of_component" controllerClass="ControllerClassName"></component><component viewClass>
Defines a custom View Class for the component instance
<component name="name_of_component" viewClass="ViewClassName"></component><component componentClass>
Defines a custom Component Class for the component instance
<component name="name_of_component" componentClass="ComponentClassName"></component><component effectClass>
Defines a custom Effect Class for the component instance
<component name="name_of_component" effectClass="EffectClassName"></component><component template-source>
Sets the tplsource property of the related instance of a component. Possible values are "none" or "default".
<component name="name_of_component" template-source="none"></component><component tplextension>
Sets the tplextension property of the related instance of a component. Possible values are any file extension. Default value is "html"
<component name="name_of_component" tplextension="tpl.html"></component>Is a helper function to let you define the templateURI for a component in a normalised way.
var templateURI = ComponentURI({
'COMPONENTS_BASE_PATH':CONFIG.get('componentsBasePath'),
'COMPONENT_NAME':'main',
'TPLEXTENSION':"tpl.html",
'TPL_SOURCE':"default"
});
console.log(templateURI); // this will show something like "templates/components/main.tpl.html" depending on your CONFIG settingsLoads a component instance in a low level, and appends the component template content to the component body. In the most of cases you won't need to call componentLoader in order to load a component. This is automatically called by QCObjects when it's needed. componentLoader returns a promise that is resolved when the component load is done and rejected when the component load was failed.
[Promise] componentLoader(componentInstance,load_async)Where componentInstance is a component instance created by New(ComponentDefinitionClass)
componentLoader(componentInstance,load_async).then(
(successStandardResponse)=>{
// component load successful
var request = successStandardResponse.request;
var component = successStandardResponse.component;
},(failStandardResponse)=>{
// component load failed
var component = failStandardResponse.component;
});Rebuilds every component that is a child element of the DOM element who owns the method. In the most of cases, you won't need to call buildComponents in order to build or rebuild every component in the DOM. This is automatically called by QCObjects when it's needed.
[element].buildComponents()document.buildComponents()A built-in QCObjects Class to define a controller
A built-in QCObjects View to define a view
A built-in QCObjects Class to define a value object
A QCObjects class type for services.
[Service].domain Returns a string with the domain of your application. It is automatically set by QCObjects at the load time.
[Service].basePath Returns a string with the base path url of your application. It is automatically set by QCObjects at the load time.
[Service].url Is a string representing the entire url of the service. It can be absolute or relative to the basePath when it applies. It can be also an external url.
NOTE: To load a service of an external resource you need to specify the external parameter to true using serviceLoader.
[Service].name Is a string representing the name of a component. The name of a service can be any alphanumeric value that identifies the service instance. It isn't a unique ID but only a descriptive name.
[Service].method Is a string representing a HTTP or HTTPS method. Possible values are: "GET", "POST", "PUT", ... any other that is accepted by REST services calls.
[Service].data Is an object representing the data of the service. When QCObjects loads a service. It receives the response and interpretes it as a template. So once a service response is obtained, 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 service instance).
[Service].cached Is a boolean value that tells QCObjects if the service response needs to be cached or not. When a service is cached, the template content loaded from the service url will be loaded only once. You have to set this value to false for every Service instance you define in order to asure the service is loaded from the resource but not the storage cache.
[Service].set('prop',value) Sets a value for a service property.
[Service].get('prop') Returns the value of a service property
Loads a service instance and returns a promise that is resolved when the service has a successful response load and is rejected when it fails loading the response.
[Promise] serviceLoader(serviceInstance)Class('MyTestService',Service,{
name:'myservice',
external:true,
cached:false,
method:'GET',
headers:{'Content-Type':'application/json'},
url:'https://api.github.com/orgs/QuickCorp/repos',
withCredentials:false,
_new_:()=>{
// service instantiated
},
done:()=>{
// service loaded
}
});
var service = serviceLoader(New(MyTestService,{
data:{param1:1}
})).then(
(successfulResponse)=>{
// This will show the service response as a plain text
console.log(successfulResponse.service.template);
},
(failedResponse)=>{
});Is a built-in definition for a JSON Service Class
[JSONService].domain Returns a string with the domain of your application. It is automatically set by QCObjects at the load time.
[JSONService].basePath Returns a string with the base path url of your application. It is automatically set by QCObjects at the load time.
[JSONService].url Is a string representing the entire url of the service. It can be absolute or relative to the basePath when it applies. It can be also an external url.
NOTE: To load a service of an external resource you need to specify the external parameter to true using serviceLoader.
[JSONService].name Is a string representing the name of a component. The name of a service can be any alphanumeric value that identifies the service instance. It isn't a unique ID but only a descriptive name.
[JSONService].method Is a string representing a HTTP or HTTPS method. Possible values are: "GET", "POST", "PUT", ... any other that is accepted by REST services calls.
[JSONService].data Is an object representing the data of the service. When QCObjects loads a service. It receives the response and interpretes it as a template. So once a service response is obtained, 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 service instance).
[JSONService].cached Is a boolean value that tells QCObjects if the service response needs to be cached or not. When a service is cached, the template content loaded from the service url will be loaded only once. You have to set this value to false for every Service instance you define in order to asure the service is loaded from the resource but not the storage cache.
[JSONService].set('prop',value) Sets a value for a service property.
[JSONService].get('prop') Returns the value of a service property
