@cypress/unique-selector NPM

unique-selector

Given a DOM node, return a unique CSS selector matching only that element. This is particularly useful when tracking in custom variables in analytics:

document.addEventListener('click', function(event) {
    var selector = unique(event.target);

    _gaq.push(['_trackEvent', 'Engagement', 'Click', selector]);
}, false);

Selector uniqueness is determined based on the given element's root node. Elements rendered within Shadow DOM will derive a selector unique within the associated ShadowRoot context. Otherwise, a selector unique within an element's owning document will be derived.
