Components

Components are Objects extended by JFactoryTraits to provide the features of jFactory.

Component Creation

Create a Component (literal)

The shortcut jFactory(name, ...sources) creates a component using the class JFactoryComponent that provides all the default Traits. It also imports the properties and methods given as a second parameter into the new component.

This is suitable for Object Literal declarations, when you don’t need Object Inheritance:

import { jFactory } from "jfactory";

let myComponent = jFactory('myComponentName', {
    myProperty: 123,
    myMethod: function() {}
})

Create a Component (inherit)

You can create your Class component by inheriting from JFactoryComponent (which inherits from JFactoryCoreObject)

import { JFactoryComponent } from "jfactory";

class MyComponentClass extends JFactoryComponent {
    constructor(name, arg1) {
        super(name);
        this.arg1 = arg1;
    }
}

let myComponent1 = new MyComponentClass('Component1', 123);
await myComponent1.$install(true);

Create a Component (base class)

Alternatively, JFactoryTraits can transform any Class to a jFactory Component Class (including Classes that extends HTMLElement to create Web Components).

Here is an example with a custom Component Base Class, and a custom shortcut that produce the same behavior as jFactory() :

import { JFactoryCoreObject, JFactoryComponent } from "jfactory";

class MyCustomComponentBase {
    constructor(name) {

        JFactoryCoreObject.inject(this, MyCustomComponentBase, name);
        JFactoryComponent.inject(this, MyCustomComponentBase);

        /*
        Shortcut to:        
        jFactoryTraits(this, MyCustomComponentBase)
            // JFactoryCoreObject
            .use(jFactory.TraitCore)
            .use(jFactory.TraitAbout, {name})
            .use(jFactory.TraitLog)
            .use(jFactory.TraitEvents)
            .use(jFactory.TraitState)
            .use(jFactory.TraitService)
            .use(jFactory.TraitTask)        
            // JFactoryComponent
            .use(jFactory.TraitFetch)
            .use(jFactory.TraitDOM)
            .use(jFactory.TraitCSS)
            .use(jFactory.TraitMutation)
            .use(jFactory.TraitTimeout)
            .use(jFactory.TraitInterval)
            .use(jFactory.TraitLibVue)
            .use(jFactory.TraitLibReact);
        */
    }
}

function createComponent(name, properties) {
    return Object.assign(new MyCustomComponentBase(name), properties)
}

let myComponent1 = createComponent('Component1', {
    myProperty: 123,
    myMethod: function() {alert(this.myProperty)}
});

let myComponent2 = createComponent('Component2', {
    sayHello: function() {alert('hello')}
});

Also works with inheritance:

import { JFactoryCoreObject, JFactoryComponent } from "jfactory";

class ComponentTypeA {
    constructor(name, value) {
        JFactoryCoreObject.inject(this, ComponentTypeA, name);

        /* shortcut to:
        jFactoryTraits(this, ComponentTypeA)
            .use(jFactory.TraitCore)
            .use(jFactory.TraitAbout, {name})
            .use(jFactory.TraitLog)
            .use(jFactory.TraitEvents)
            .use(jFactory.TraitState)
            .use(jFactory.TraitService)
            .use(jFactory.TraitTask);        
        */

        this.myProperty = value;
    }
    myMethod() {alert(this.myProperty)}
}

class ComponentTypeB extends ComponentTypeA {
    constructor(name, value) {
        super(name, value);
        JFactoryComponent.inject(this, ComponentTypeB);

        /* shortcut to:
        jFactoryTraits(this, ComponentTypeB)
            .use(jFactory.TraitFetch)
            .use(jFactory.TraitDOM)
            .use(jFactory.TraitCSS)
            .use(jFactory.TraitMutation)
            .use(jFactory.TraitTimeout)
            .use(jFactory.TraitInterval)
            .use(jFactory.TraitLibVue)
            .use(jFactory.TraitLibReact);
        */    
    }
    sayHello() {alert('hello')}
}

let myComponent1 = new ComponentTypeA('Component1', 123);
let myComponent2 = new ComponentTypeB('Component2');
