Usage

Import the module and add it to your imports section in your main AppModule:

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

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { NgxIonicImageViewerModule } from 'ngx-ionic-image-viewer';

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [
    AppRoutingModule,
    BrowserModule,
    IonicModule.forRoot(),
    NgxIonicImageViewerModule
  ],
  providers: [
    StatusBar,
    SplashScreen,
      { 
        provide: RouteReuseStrategy,
        useClass: IonicRouteStrategy
      }
    ],
  bootstrap: [AppComponent]
})
export class AppModule {}

Import the module and add it to your imports section of your component where you want to use it (e.g. home.module.ts):

import { NgxIonicImageViewerModule } from 'ngx-ionic-image-viewer';

...

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    IonicModule,
    RouterModule.forChild([
      {
        path: '',
        component: HomePage
      }
    ]),
    NgxIonicImageViewerModule
  ],
  declarations: [HomePage]
})
export class HomePageModule {}

Add ion-img-viewer within the HTML of your module (e.g. home.page.html)

<ion-header>
  <ion-toolbar>
    <ion-title>
      Ionic Blank
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
  <div class="ion-padding">
    The world is your oyster.
  </div>
  <ion-img-viewer title="" alt="" text="" src="./assets/img/demo.jpg"></ion-img-viewer>
</ion-content>

Workspace

This project was generated with Angular CLI version 8.3.14.

Development server

1. Run the build command every time a file change

   ./ngx-ionic-image-viewer-workspace $ ng build --watch
   

2. Create a local symlink using npm link that can then be used in the project where you want to integrate the package as you don’t want to build, publish and update a library all the time while testing.

   ./ngx-ionic-image-viewer-workspace/dist/ngx-ionic-image-viewer $ npm link
   

3. Run the npm link command inside the projects folder to link the global installation target into your project’s node_modules folder.

   ./ngx-ionic-image-viewer-workspace/demo $ npm link ngx-ionic-image-viewer
   

4. Start a local dev server for app dev/testing. Navigate to http://localhost:8100/. The app will automatically reload if you change any of the source files.

   ./ngx-ionic-image-viewer-workspace/demo $ ionic serve
   

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Publishing

After building your library with ng build ngx-wordpress, go to the dist folder cd dist/ngx-wordpress and run npm publish.

Running unit tests

Run ng test to execute the unit tests via Karma.

Running end-to-end tests

Run ng e2e to execute the end-to-end tests via Protractor.
