Introducing Shadow DOM API
At first I was gung ho about web components. I was so excited I used Mozilla's X-Tag for one project and Polymer in another project. I am now no longer in favor of using them and it makes me sad, actually.Web components are simply too heavy. They add latency to download (yeah you can combine them but I've never found tooling (including Vulcanize) that worked very well). Also the shadow dom's separation makes styling more difficult across multiple components requiring awkward shadow dom hacks in the CSS and / or duplicating / adding more CSS to components themselves. Same with using JavaScript and third party libraries not expecting to use the ShadowDom though this isn't so bad.When I'm working on something that needs to be optimized for low bandwidth / high latency I go as lightweight as possible and I concat as much stuff together as I can. I want web components to work so badly but they're way too slow for me to use anytime soon.
