Here’s another nice progressive web component for your forms, this time for showing error messages.
This is a superb way to deprecate a little JavaScript library. Now that you can just use HTML instead, the website for Pikaday has been turned into a guide to choosing the right design pattern for your needs. Bravo!
Pikaday is no longer a JavaScript date picker. Pikaday is now a friendly guide for front-end developers. I want to push developers away from the classic date picker entirely. Especially fat JavaScript libraries.
It’s great to see the evolution of HTML happening in response to real use-cases—the turbo-charging of the select element just gets better and better!
Trys describes exactly the situation where you really do need to use the Shadow DOM in a web component—as opposed to just sticking to HTML web components—, and that’s when the component is going to be distributed and you have no idea where:
This component needed to be incredibly portable, looking great on any third-party website, in any position, at any viewport, with any amount of content. It had to be a “hyper-responsive” component.
This is a good description of the appeal of HTML web components:
WC lifecycles are crazy simple: you register the component with
customElements.defineand it’s off to the races. Just write a class and the browser will take care of elements appearing and disappearing for you, regardless of whether they came from a full reload, a fetch request, or—god forbid—adocument.write. The syntax looks great in markup, too: no more having to decorate withjs-somethingclasses or data attributes, you just wrap your shit in a custom element calledsomething-controllerand everyone can see what you’re up to. Since I’m firmly in camp “progressively enhance or go home” this fits me like a glove, and I also have great hopes for Web Components improving the poor state of pulling in epic dependencies like date pickers or text editors.
The power of interoperability:
Web components won’t take web development by storm, or show us the One True Way to build websites. They don’t need to dethrone JavaScript frameworks. We probably won’t even all learn how to write them!
What web components will do — at least, I hope — is let us collectively build a rich ecosystem of dynamic components that work with any web stack. No more silos. That’s the web component success story.
Mobile Safari doesn’t support the min and max attributes on date inputs.
A question via email…
The `details` element is like the TL;DR of markup.
It’s not just about finding the issues—it’s about finding the issues at the right time.
