singlepageapp

/* Welcome to lib-singlepageapp.js! This script is meant to handle using single-page
applications (SPAs) for Tealium when you do not have direct access to Angular, Vue,
React, etc. for making modifications. This allows us to get around limitations of
utag.view(). The trigger in this case is a global event listener that evaluates
any time there is a click. If a new URL is populated via the history API, we'll treat
that as a "pageview". Note in this case that I have defined a UDO variable of page.
This variable is then mapped to anything requiring a page URL. For example, in GA I
have this variable mapped to config.page_location so it acts like a native page URL view.*/

//Set up our utag configuration to treat everything as noview until we tell it otherwise
window.utag_cfg_ovrd =  window.utag_cfg_ovrd || {};
window.utag_cfg_ovrd.noview = true;

// Listen for changes on the URL itself once there is a click as our trigger for recording "pageviews".
let url = location.href;
document.body.addEventListener('click', () => {
    requestAnimationFrame(() => {
        url !== location.href && utag.view({
            "page": document.URL
        });
        url = location.href;
    });
}, true);
