ngx-ionic-image-viewer
Advanced tools
An Ionic 4 Angular module to view & zoom on images and photos without any additional dependencies.
ℹ️ Please note that this package has reached its end. After getting into the React world 2018, I lost the contact into the Angular Ecosystem. With Ionic 6, Slider.js will also be split off, which will probably make this package incompatible for now. Unfortunately I don't have the time to develop this package further according to the demands - thank you for your trust and responses, I appreciated it very much. Feel free to fork this package and work on a successor. You will find here a good tutorial how to create your own image viewer, which is based on the same approach: https://www.youtube.com/watch?v=VCUpRkRi00w
An Ionic 4 Angular module to view & zoom on images and photos without any additional dependencies.
npm install --save ngx-ionic-image-viewer
Import the module and add it to your imports section in your main AppModule:
import { NgxIonicImageViewerModule } from 'ngx-ionic-image-viewer';
...
@NgModule({
imports: [
NgxIonicImageViewerModule
],
})
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: [
NgxIonicImageViewerModule
],
})
export class HomePageModule {}
Add ion-img-viewer within the HTML of your module (e.g. home.page.html)
<ion-img-viewer
title="Demo"
text="Component"
scheme="dark"
src="./assets/img/demo.jpg"
>
</ion-img-viewer>
Add ionImgViewer as a directive within the ion-img HTML element of your module (e.g. home.page.html)
<ion-img
ionImgViewer
title="Demo"
text="Directive"
scheme="light"
src="./assets/img/demo.jpg"
>
</ion-img>
Import ViewerModalComponent from ngx-ionic-image-viewer and add it to the ModalController. Within the componentProps, all available properties can be passed, whereby src is always required. In addition you must add the css class ion-img-viewer to the property cssClass.
Use cssClass: ['ion-img-viewer', 'my-custom-ion-img-viewer']in case you want to add more css classes.
import { ModalController } from '@ionic/angular';
import { ViewerModalComponent } from 'ngx-ionic-image-viewer';
export class HomePage {
constructor(public modalController: ModalController) {}
async openViewer() {
const modal = await this.modalController.create({
component: ViewerModalComponent,
componentProps: {
src: "./assets/img/demo.jpg"
},
cssClass: 'ion-img-viewer',
keyboardClose: true,
showBackdrop: true
});
return await modal.present();
}
}
<ion-button (click)="openViewer()">Open Viewer</ion-button>

npm run ionic:serve
npm link: Create a local symlink 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.npm link ngx-ionic-image-viewer inside the projects folder to link the global installation target into your project’s node_modules folder.ionic serve: 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.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.
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.
