PageCacheManager

Inspired in: snapback_cache

One of the pain points of an infinite scrolling feed is maintaining the feed and scroll position when you are sent to a new page and click back to return to the feed. This little library wants to help you accomplish this easily.

Manual build

To build you only need to execute:

npm install
gulp build

This will create a /dist folder with the final JS file PageCacheManager.js and PageCacheManager.js.min.

Using NPM

You can add this to your code by running:

npm i @adearriba/cache.manager

Import library to your code

Library is using ES6 export default so you can import it to your code using:

import {PageCacheManager} from "./PageCacheManager";

How to use it

1. Configure your InfiniteScroll Create functions to execute at different moments in the lifetime of the cache manager. It is recommended to set infinite scroll after loading the cache.

function onLoaded(e){
  configureInfiniteScroll();
};

function onCached(e){
  console.log(e);
};

2. Create a cache manager instance

let cacheManagerOptions = {
	bodySelector: '#cache', //Mandatory. Selector of the HTML element you want to cache
	onLoaded: onLoaded, //Optional. Callback to execute when cache is loaded
	onCached: onCached, //Optional. Callback to execute when item is cached
};

let pageCacheManager = new PageCacheManager(cacheManagerOptions);

3. Decide when you want to cache For example, let's cache when the person clicks a product card.

document.querySelector('#product').addEventListener('click', function(e){
	pageCacheManager.cachePage();
});
