angular2-dynamic-component & angular2-dynamic-directive

An implementation of dynamic component wrapper at Angular2 [4.1.2] (AoT compatible).
Also, you must see the solution out of the box before using this component: (NgComponentOutlet, since 4.0.x)

https://angular.io/docs/ts/latest/api/common/index/NgComponentOutlet-directive.html

Description

Date of creation: 18 Jun [starting with Angular 2.0.0-rc.2].

Installation

1 At first, you need to install the core-js npm module.
2 Then you need to install the ts-metadata-helper dependency package (don't worry, it's very small and simple, I like "reusable" approach)
``sh
npm install ts-metadata-helper --save
`
3 And after that, you have to install the target package
`sh
npm install angular2-dynamic-component --save
`
4 Then you must apply the DynamicComponentModule

`typescript
import {DynamicComponentModule} from 'angular2-dynamic-component/index';

@NgModule({
imports: [DynamicComponentModule]
})
`

Demo

1 git clone --progress -v "git@github.com:apoterenko/angular2-dynamic-component.git" "D:\sources"
2 cd D:\sources\angular2-dynamic-component\demo
3 npm install
4 npm start

Features

##### 1 Support of dynamicComponentReady & dynamicComponentBeforeReady output events. See below.

##### 2 Support of dynamic-component directive. See below.

##### 3 Support of DynamicComponent component. See below.

##### 4 Support of Dynamic within Dynamic strategy (see demo inside).

`typescript
@Component(...)
export class AppComponent {
extraTemplate = ;
extraModules = [DynamicComponentModule];
...
}
`
`html

`

##### 5 Support of componentTemplateUrl attribute. This attribute allows getting resource via Angular2 HTTP/Ajax.

Also, 301, 302, 307, 308 HTTP statuses are supported (recursive redirection). The componentRemoteTemplateFactory (IComponentRemoteTemplateFactory)
attribute allows prepare http response before rendering.

`typescript
@Component(...)
export class AppComponent {
dynamicCallback(scope) {
console.log('Hi there! Context value is:', scope.contextValue); // Hi there! Context value is: 100500
}
}
`
`html

`

##### 6 Support of componentContext attribute.

This attribute can refer to owner component (via self = this) or any other object.

`typescript
@Component(...)
export class AppComponent {
self = this;
dynamicContextValue = 100500;
changedValue = 0;
dynamicExtraModules = [FormsModule];
}
`
`html

`

##### 7 Support of dynamic injected modules via the DynamicComponentModuleFactory.

The CommonModule module is imported by default.

`typescript
import {DynamicComponentModuleFactory} from "angular2-dynamic-component/index";
@NgModule({
imports: [...,
DynamicComponentModuleFactory.buildModule([
FormsModule
])
],
...
bootstrap: [AppComponent]
})
export class AppModule {}
`
`html

`

##### 8 Support of componentModules attribute.

`typescript
@Component(...)
export class AppComponent {
dynamicExtraModules = [FormsModule];
}
`
`html

`

##### 9 Support of componentType attribute.

`html

`
`typescript
@Component(...)
export class AppComponent {
columns = [{
type: TextField,
context: {
fieldName: 'description',
value: 'Test description'
}
}, {
type: CheckboxField,
context: {
fieldName: 'expired',
value: true
}
}];
ngOnInit() {
setTimeout(() => {
console.log(JSON.stringify(this.columns)); // [{"context":{"fieldName":"description","value":"Next value"}},{"context":{"fieldName":"expired","value":false}}]
}, 3000);
}
`
`typescript
import {
Component,
Input,
} from '@angular/core';

@Component({
selector: 'DynamicTextField', // It can be absent => selector === "TextField"
template: ,
})
export class TextField {
@Input() fieldName: string;
@Input() value: string;

constructor(
private appState: AppState,
private elementRef: ElementRef,
private appRef: ApplicationRef
) {
console.log('The TextField constructor has been called');
}

ngOnInit() {
setTimeout(() => this.value = this.fieldName + ': next value', 4000);
this.elementRef.nativeElement.childNodes[0].style.color = 'red';
}
}

@Component({
selector: 'DynamicCheckboxField', // It can be absent => selector === "CheckboxField"
template: ,
})
export class CheckboxField {
@Input() fieldName: string;
@Input() value: boolean;

constructor() {
console.log('The CheckboxField constructor has been called');
}

ngOnInit() {
setTimeout(() => this.value = !this.value, 1000);
}
}
``

##### 10 Support of componentTemplatePath attribute. This analogue of templateUrl parameter for @Component.
