Intercooler.js – Making AJAX as easy as anchor tags
This has been reposted so many times by the author and by others that I can't help but finally ask.What's the point? This would lead to your API being comprised of blocks of HTML which are probably only useable for one product. Why not just use REST + JSON? It would take no more than five minutes to set up client-side rendering, and you could even make it attribute-based like this with barely any more effort. Is it really not worth spending the extra five minutes it takes to set things up in a way that is reusable and standard? All I see is piles of legacy code being generated where it hurts most - in the backend.This took me 10 minutes to cook up. It would have taken about three if I hadn't forgotten the jQuery and Handlebars APIs. This allows you to POST to a JSON API using two attributes. Untested of course, but you get the idea:    Example: 

    $('[ic-post-to]').click((button) => {
        fetch($(button).attr('ic-post-to')), { method: 'post' })
        .then((result) => {
            let templateText = $($(button).attr("ic-template")).html();
            let template = Handlebars.compile(templateText);
            let resultHtml = template(result);
            $(button).replaceWith(resultHtml);
        });
    });
