如何使用Angular CLI实现ng2-ui（NPM包）？

Question

I wish to use the following NPM package with Angular CLI: ng2-ui

The implementation guide is for SystemJS, and not for Webpack, what is used by Angular CLI , what I have to use in this project.

What did I already do?

• Installed the package by npm install ng2-ui --save

• Added the following line to app.module.ts

   import { Ng2UIModule } from 'ng2-ui'; 

• Added Ng2UIModule to the imports array in @NgModule .

By this point I didn't use Ng2UIModule in any of the components yet and before doing the mentioned operations the application worked just fine.

When I try to run the application by ng serve , I get the following error in console:

ERROR in [default] C:\tools\test-package.net\node_modules\ng2-ui\dist\index.d.ts:1:31
Cannot find module 'ng2-overlay'.

ERROR in [default] C:\tools\test-package.net\node_modules\ng2-ui\dist\index.d.ts:2:32
Cannot find module 'ng2-map'.

ERROR in [default] C:\tools\test-package.net\node_modules\ng2-ui\dist\index.d.ts:3:60
Cannot find module 'ng2-popup'.

ERROR in [default] C:\tools\test-package.net\node_modules\ng2-ui\dist\index.d.ts:4:39
Cannot find module 'ng2-scrollable'.

I guess the application simply lacks the following systemjs.config.js settings:

map['ng2-ui'] =  'node_modules/ng2-ui/dist';
packages['ng2-ui'] = {main: 'ng2-ui.umd.js', defaultExtension: 'js'}

Just I don't know how to make it work in the Angular CLI version of Webpack...

(Currently I use Angular CLI 1.0.0-beta.17)

Thanks for your help!

the ng2-ui has been changed to @ngui/overlay https://github.com/ng2-ui/overlay .

Here is my sample code.

ex.component.html

 <div id='div1' class='container row'> Div 1 </div> <div id="overlay" ngui-overlay-of="div1" style='background-color:black'> Loading data...... </div> <div id="overlay2" ngui-overlay-of="div1" style='background-color:blue'> Loading data...... </div> <button (click)="showOverlay($event)" class='btn btn-success'>Show Overlay</button> <button (click)="hideOverlay()" class='btn btn-danger'>Hide Overlay</button> <br /><br /> <button (click)="showOverlay2($event)" class='btn btn-success'>Show Overlay</button> <button (click)="hideOverlay2()" class='btn btn-danger'>Hide Overlay</button> 

ex.component.ts

 import { Component, OnInit } from '@angular/core'; import { NguiOverlayManager } from '@ngui/overlay'; @Component({ selector: 'app-ex', templateUrl: './ex.component.html', styleUrls: [ './ex.component.css' ], providers:[NguiOverlayManager] }) export class ExComponent implements OnInit { constructor(private overManager:NguiOverlayManager) { } ngOnInit() { } showOverlay(event: Event) { this.overManager.open('overlay',event); } hideOverlay() { this.overManager.close('overlay'); } showOverlay2(event: Event) { this.overManager.open('overlay2', event); } hideOverlay2() { this.overManager.close('overlay2'); } } 

Add import { NguiOverlayModule } from '@ngui/overlay'; to the module and add NguiOverlayModule to the imports array.
