Lazyload plugin

Really small lazyload plugin for vue (<7kB).

If you have a idea for a new feature or option, add it to the Issues on my github repo. :)

How to install:

1. Install the package:

   #install the npm package
   
   npm i vt-lazyload

2. Import/use plgun:

   import Vue from "vue";
   import lazyLoad from "vt-lazyload";
   
   Vue.use(lazyLoad);

How to use:

Add the v-lazyLoad directive with the src of the image as attribute value.

Do not add the src Attribute or else that lazyload wont work.

With url:

<img v-lazyLoad="'https://via.placeholder.com/350x150'" />

With prob/variable:

<img v-lazyLoad="image.src" />

lazyloading:

When using this plugin on a browser that supports native lazyloading, the plugin automaticly adds the necessary attributes and values to your element with the v-lazyload directive.

If you add options to the Vue.use() the native lazyloading won't be added to your element. Therefore the custom lazyload will be added to the element

Options:

How to add a option:

Add a object to the Vue.use(lazyload)

Vue.use(lazyLoad, { margin: "0px 0px 100px 0px" });

Options:

| Option | Type | Default value | Description | | ---------- | ------- | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | | margin | string | '0px 0px 100px 0px' | Sets the distance between the viewport and the image before it gets loaded | | fadeIn | boolean | false | If you want the images to fade in when scrolling by, set the value to a css transition e.g. 'opacity 0.3s ease' | | directive | string | 'lazyLoad' | Use this option to change the directive name, if you change it to 'lazy' the directive name becomes v-lazy | | cssAnimate | boolean | false | Use Animate.css on your lazyload image | | errorImg | string | false | Sets a placeholder image when image couldn't load, to use this function passtrough the url of the placeholder image | | errorClass | string | imageFailed | This class name will be added to the image when it failed to load. Add errorClass with the class name you like to the options to change the default classname. |

Using multiple options:

Vue.Use(lazyLoad, {
  margin: "0px 0px 50px 0px",
  errorImg:
    "https://cdn.dribbble.com/users/1274627/screenshots/3390285/404-error-sad-boat-800x600.jpg"
});

How to use the cssAnimate option:

1. Find the animation you want on animate.css

2. Add the animation in the animation array and add some options if you want. (The order of the array doesnt matter)

<img v-lazyLoad="{ url: backgroundImage, animation: ['zoomInLeft', 'slower'] }" />
