Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

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

This package was originally a fork from https://github.com/jelgblad/angular2-masonry to allow it to work with newer versions of Angular.

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

Installation

npm install ng-masonry-layout --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>
       <div ngxMasonryItem class="masonry-item" *ngFor="let item of masonryItems">
        {{item.title}}
      </div>
     </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' }
  ];
}

Configuration

Options

Read about Masonry options here: Masonry Options

The options-attribute takes an object with the following properties:

  • itemSelector: string;
  • columnWidth: number | string;
  • gutter: number;
  • percentPosition: boolean;
  • stamp: string;
  • fitWidth: boolean;
  • originLeft: boolean;
  • originTop: boolean;
  • containerStyle: string;
  • transitionDuration: string;
  • resize: boolean;
  • initLayout: boolean;
  • horizontalOrder: boolean;

Examples

Inline object:

<ngx-masonry [options]="{ transitionDuration: '0.8s' }"></ngx-masonry>

From parent component:

import { NgxMasonryOptions } from 'ngx-masonry';

public myOptions: MasonryOptions = {
  transitionDuration: '0.8s'
};
<ngx-masonry [options]="myOptions"></ngx-masonry>

imagesLoaded

NOTE: Will throw error if global imagesLoaded not available.

Delay adding brick until all images in brick are loaded. To activate imagesLoaded set useImagesLoaded to true.

<ngx-masonry [useImagesLoaded]="true"></ngx-masonry>

index.html:

<script src="https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.min.js"></script>

check the ImagesLoaded website for the latest version.

updateLayout

ngx-masonry has an input property, updateLayout, which accepts a boolean and will call masonry's layout() method on a change. It ignores the first change when the component loads.

<ngx-masonry [updateLayout]="updateMasonryLayout"></ngx-masonry>

When updateMasonryLayout is updated, the layout() method will be called.

Events

layoutComplete: EventEmitter<any[]>

Triggered after a layout and all positioning transitions have completed.

removeComplete: EventEmitter<any[]>

Triggered after an item element has been removed.

FAQ

  • Why is it rendering the tiles twice in prod? This could be the case because of angulars build optimizer. A currently working "workaround" is disabling the build-optimizer in the angular.json file.
{
  "projects": {
    "my-project": {
      "architect": {
        "build": {
            "production": {
              "buildOptimizer": false
            }
          }
        }
    }
  }
}

For more information refer to this issue:
https://github.com/gethinoakes/ngx-masonry/issues/8

Examples

<ngx-masonry (layoutComplete)="doStuff($event)" (removeComplete)="doOtherStuff($event)"></ngx-masonry>

Demo

This repository contains a working app using ngx-masonry as a child module, not as an npm package. You can go to the demo respository to view an app that uses it as an npm package.
