Extensible Web Components” by Jeremy Keith via Adactio

As always, insightful progressive enhancement thoughts around service workers vs. web components:

The next question we usually ask when we’re evaluating a technology is “how well does it work?” Personally, I think it’s just as important to ask “how well does it fail?”

Service workers work well and fail well. If a browser supports service workers, the user gets all the benefits. If a browser doesn’t support service workers, the user get the same experience they would have always had. Web components (will) work well, but fail badly. If a browser supports web components, the user gets the experience that the developer has crafted using these new technologies. If a browser doesn’t support web components, the user gets…probably nothing. It depends on how the web components have been designed.

It’s so much easier to get excited about implementing service workers. You’ve literally got nothing to lose and everything to gain.
