ngx-masonry

Angular Module for displaying a feed of items in a masonry layout using https://github.com/desandro/masonry

This package is a fork from https://github.com/jelgblad/angular2-masonry to update it to work for newer Angular releases as no work seems to have been done on it for almost 12 months (at the time of writing this).

If I have the time I will look into further improvements, but please do not expect support as I don't have the time for that.

This updated version is also compatible with Angular Universal server side rendering (SSR)

ngx-masonry is in development and not ready for production use. Feel free to install and try it out, but depend on it at your own risk.

Installation

npm install ngx-masonry --save

If you're using SystemJS add ngx-masonry and masonry-layout to your configuration:

packages: {
  "ngx-masonry": { "defaultExtension": "js", "main": "index" }
},
map: {
  "ngx-masonry": "node_modules/ngx-masonry",
  "masonry-layout": "node_modules/masonry-layout/dist/masonry.pkgd.js"
}

Usage

Import NgxMasonryModule into your app's modules:

import { NgxMasonryModule } from 'ngx-masonry';

@NgModule({
  imports: [
    NgxMasonryModule
  ]
})

 @Component({
   selector: 'my-component',
   template: `
     <ngx-masonry>
       <ngx-masonry-item class="masonry-item" *ngFor="let item of masonryItems">{{item.title}}</ngx-masonry-item>
     </ngx-masonry>
     `,
     styles: [`
       .masonry-item { width: 200px; }
     `]
 })
 class MyComponent {
   masonryItems = [
     {title: 'item 1'},
     {title: 'item 2'},
     {title: 'item 3'},
     {title: 'item 4'},
     {title: 'item 5'},
     {title: 'item 6'}
   ]
 }

From parent component:

public myOptions: MasonryOptions = { 
  transitionDuration: '0.8s' 
};

<ngx-masonry [options]="myOptions"></ngx-masonry>
