Ng Lazy Load

npm version Build Status

Lazy loading images with Angular.

Table of Contents:

Installation

To install this library, run:

$ npm install @greg-md/ng-lazy-load --save

How It Works

Setting up in a module

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

// 1. Import lazy loading module;
import { LazyLoadModule } from '@greg-md/ng-lazy-load';

import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    // 2. Register lazy loading module.
    LazyLoadModule,
  ],
  declarations: [
    AppComponent,
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Using in templates

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <img src="loading.jpg" lazy-load="lazy-image.jpg" />
  `,
})
export class AppComponent { }

Directive Attributes

threshold

By default images are loaded when they appear on the screen. If you want images to load earlier, use threshold parameter. Setting threshold to 200 causes image to load 200 pixels before it appears on viewport.

Example:

<img src="loading.jpg" lazy-load="lazy-image.jpg" threshold="200" />

container

You can also use directive for images inside scrolling container, such as div with scrollbar. Just pass the container element.

Example:

<div #container>
    <img src="loading.jpg" lazy-load="lazy-image.jpg" threshold="200" [container]="container" />
</div>

bg-src

Set default image in background and lazy load image directly in the src attribute.

Useful with non-effective image URLs. This will avoid to load lazy image twice.

Example:

<img bg-src="loading.jpg" lazy-load="lazy-image.jpg" width="200" height="200" />
