NgxLazyImagesApp

An Angular library that lazy load images with IntersectionObserver API

Features

Smart lazy loading logic using IntersectionObserver
- The Intersection Observer API provides a way to asynchronously observe changes in the intersection of a target element with an ancestor element or with a top-level document’s viewport. -MDN
Speed up initial page loads by loading only images above the fold
Decreases load time
Decreases speed index
Decrease above the fold time
Responsive with placeholders

Getting Started

First install through npm:

1npm install --save ngx-lazy-loading-images

Import the ngx-lazy-loading-images module into your apps module:

1import { NgModule } from '@angular/core';
2import { NgxLazyImagesModule } from ngx-lazy-loading-images;
3
4@NgModule({
5  imports: [
6    ...
7    NgxLazyImagesModule
8  ],
9  ...
10})
11export class AppModule { }

Add NgxLazyLoadingImagesComponent to your view:

NgxLazyLoadingImagesComponent

What is it? - Angular component that lazy loads images with IntersectionObserver

1  <ngx-lazy-loading-images
2      [src]="'https://via.placeholder.com/300x300'"
3      [height]="'300'"
4      [width]="'300'"
5  ></ngx-lazy-loading-images>

API

NgxLazyLoadingImagesComponent

@Input [config]

Intersection observer options

The options object passed into the [config] input object is passed into the IntersectionObserver() constructor and lets you control the circumstances under which the observer's callback is invoked. It has the following fields:

root:
- The element that is used as the viewport for checking visiblity of the target. Must be the ancestor of the target. Defaults to the browser viewport if not specified or if null.
rootMargin:
- Margin around the root. Can have values similar to the CSS margin property, e.g. "10px 20px 30px 40px" (top, right, bottom, left). The values can be percentages. This set of values serves to grow or shrink each side of the root element's bounding box before computing intersections. Defaults to all zeros.
threshold:
- Either a single number or an array of numbers which indicate at what percentage of the target's visibility the observer's callback should be executed. If you only want to detect when visibility passes the 50% mark, you can use a value of 0.5. If you want the callback to run every time visibility passes another 25%, you would specify the array [0, 0.25, 0.5, 0.75, 1]. The default is 0 (meaning as soon as even one pixel is visible, the callback will be run). A value of 1.0 means that the threshold isn't considered passed until every pixel is visible.

Other @Inputs

Image component working similar with standard img tag and with the following props.

Input	Type	Required	Description
`src`	string	✓	The image source. eg: 'https://via.placeholder.com/300x300'
`height`	number		Image height (Defaults to img src height)
`width`	number		Image width (Defaults to img src width)
`alt`	string		This attribute defines an alternative text description of the image.
`placeholder`	string		Placeholder until image loads. A CSS `background` property, eg: `#3A6073` or `linear-gradient(to right, #4389A2, #5C258D)`. Defaults to `linear-gradient(to right, #3A6073, #16222A)`.

Example:

1  import {Component, OnInit} from '@angular/core';
2  
3  @Component({
4    selector: 'app-root',
5    templateUrl: './app.component.html',
6    styleUrls: ['./app.component.scss']
7  })
8  export class AppComponent implements OnInit {
9    title = ngx-lazy-loading-images;
10    config: IntersectionObserverInit;
11  
12    ngOnInit(): void {
13      const $rootElement = document.querySelector('.container');
14      this.config = {
15        root: $rootElement,
16        rootMargin: '0px 0px 200px 0px'
17      };
18    }
19  }

1  <ngx-lazy-loading-images
2    [src]="'https://via.placeholder.com/300x300'"
3    [alt]="'300X300'"
4    [config]="config"
5    [height]="'300'"
6    [width]="300"
7  ></ngx-lazy-loading-images>

Development

Clone repo
Install dependencies:

1npm install

Building the Library

Before we can use ng-surveys library we need to build it:

1ng build ng-surveys

With Angular CLI v6.2 we can use the --watch flag so that every time a file changes Angular CLI performs a partial build that emits the amended files:

1ng build ng-surveys --watch || npm run start:lib

Run the application project (demo app to test our library):

1ng serve || npm run start

Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

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.

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.

Further help

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
