ng-dynamic-component-loader v1.0.2

NgDynamicComponentLoader

A simple service that will dynamically add a component to the DOM at run time. Depending on the location provided, you can attach a component to a ViewContainer, an HTML element, or the root of the application. This makes it very easy to add components such as notifications, alerts or modals anywhere in the DOM.

Install

npm i --save ng-dynamic-component-loader

Usage

For dynamic components, they need to be added to the entryComponents of your module that they will be used in.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { DynamicComponentComponent } from './dynamic-component/dynamic-component.component';

@NgModule({
  declarations: [
    AppComponent,
    DynamicComponentComponent
  ],
  entryComponents: [DynamicComponentComponent],
  imports: [
    BrowserModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Then in your parent component

import { Component } from '@angular/core';

import { NgDynamicComponentLoader } from 'ng-dynamic-component-loader';
import { DynamicComponentComponent } from './dynamic-component/dynamic-component.component';

@Component({
  selector: 'app-root',
  template: `
    <button (click)="addComponent()">Add Dynamic Component</button>
  `,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private loader: NgDynamicComponentLoader) {}

  addComponent() {
    // if no location is passed, then the component will be 
    // attached to the root element of the application
    this.loader.attachComponent(DynamicComponentComponent)
  }
}
