ionic-image-cache v1.0.1

ionic-image-cache

Custom HTML element for use with Ionic that lazy loads and caches images based on vanilla JS and Capacitor plugins

Installation

Install the package:

npm install ionic-image-cache

Now, all you have to do is insert this line in your HTML page:

<script type="module" src="../node_modules/ionic-image-cache/dist/index.js"></script>

Adjust the path to reflect the correct location of your "node_modules" folder in relation to your HTML file.

To rebuild the distribution script, if needed, type:

npm run build

Basic Usage

Replace your <img> tags:

<img src="image.jpg" />

For:

<img is="img-cache" url="image.jpg" />

Notice the attribute "src" must be replaced by "url".

Optional Attributes

Lazy Load

Defers loading the image until the element is visible in the viewport

<img is="img-cache" url="image.jpg" lazy />

Expiration Time

Deletes the old image and downloads a new one after a number of minutes

<img is="img-cache" url="image.jpg" expire="720" />

Clear cache

Empties the cache

<img is="img-cache" url="image.jpg" clear />

Note: All three attributes can be combined:

<img is="img-cache" url="image.jpg" clear lazy expire="10" />
