OCCS (Oracle Commerce Cloud Service) is a single-page application. All pages are dynamic and there is just one page that changes content based on the requirements (e.g. a URL change).

This causes problems when integrating with JavaScript libraries that need a reload/re-invocation every time a page loads, because they need an actual page load to occur for them to work properly.
One example of such a library is Google Trusted Store.

This article outlines a workaround to make sure that the library reloads when the page changes on OCCS. The following points are to be noted while working on this:

  1. OCCS uses requireJs to dynamically load a library when required. Once loaded, the library is not loaded again and the cached version of the library is used. However, requireJs has the require.undef method that can be used to "undefine" a particular library and which will cause it to be reloaded.
  2. OCCS has a set of JQuery callbacks (pubsub) that publishes events such as page change, page loaded etc. These are very useful to find out when a page is changed/ ready.

The work around uses this information to create a pseudo page change and unload and load a library when required.
