Features

1 Support of dynamic-template directive.

<ng-template dynamic-template
             [template]="'<span style=\'color: orange;\'>This is simple dynamic template</span>'">
</ng-template>

2 Support of lazy loaded component modules for the dynamic templates via lazyModules input parameter (demo scenario #4).

<ng-template dynamic-template
             [template]="'<lazy-component></lazy-component>'"
             [lazyModules]="['lazy']">
</ng-template>

export const ROUTES: Routes = [
  { path: '',      component: HomeComponent },
  ...
  { path: 'lazy', loadChildren: './lazy/lazy.module#LazyModule' }
];

...

@NgModule({
  imports: [
    ...
    NgxDynamicTemplateModule.forRoot({ routes: ROUTES }),
    RouterModule.forRoot(ROUTES)
  ],

3 Support of httpUrl attribute. This attribute allows getting resource via Angular2 HTTP/Ajax (demo scenario #3).

Also 301, 302, 307, 308 HTTP statuses are supported (recursive redirection). The remoteTemplateFactory is an optional attribute allows parse response and build http request.

<ng-template dynamic-template
             [httpUrl]="'https://httpbin.org/get'"
             [defaultTemplate]="'<span>on error template</span>'"
             [remoteTemplateFactory]="remoteTemplateFactory">
</ng-template>

  import { Component, OnInit } from '@angular/core';
  import { HttpHeaders } from '@angular/common/http';
  import { IDynamicRemoteTemplateFactory, DynamicHttpResponseT, IDynamicHttpRequest } from 'ngx-dynamic-template';
  ...
  remoteTemplateFactory: IDynamicRemoteTemplateFactory = {
    // This is an optional method
    buildRequestOptions (): IDynamicHttpRequest {
      const headers = new HttpHeaders();
      headers.append('Token', '100500');

      return {
        withCredentials: true,
        headers: headers
      };
    },
    // This is an optional method
    parseResponse (response: DynamicHttpResponseT): string {
      return response.body.headers['User-Agent'];
    }
  };

4 Support for injecting the extra modules via extraModules input parameter.

<ng-template dynamic-template
             [template]="template4"
             [context]="context4"
             [extraModules]="[myExtraModule]"></ng-template>

5 Support of caching of compiled modules for the specific dynamic template. Therefore you can render a huge amount of dynamic templates at the same time (demo scenario #5).

6 Support of recursive injection the dynamic module instance (dynamic component inside dynamic component).

7 Clearing dynamic wrapper using the removeDynamicWrapper option.

NgxDynamicTemplateModule.forRoot({ removeDynamicWrapper: true });
