My approach to HTML web components. Some neat patterns here from Jeremy Keith, who is using Web Components extensively for progressive enhancement of existing markup.
The reactivity you get with full-on frameworks [like React and Vue] isn’t something that web components offer. But I do think web components can replace jQuery and other approaches to scripting the DOM.
Jeremy likes naming components with their element as a prefix (since all element names must contain at least one hyphen), and suggests building components under the single responsibility principle - so you can do things like <button-confirm><button-clipboard><button>....
Jeremy configure buttons with data- attributes and has them communicate with each other using custom events.
Something I hadn't realized is that since the connectedCallback function on a custom element is fired any time that element is attached to a page you can fetch() and then insertHTML content that includes elements and know that they will initialize themselves without needing any extra logic - great for the kind of pattern encourages by systems such as HTMX. # 30th April 2024, 11:02 am
Introducing Enhance WASM (via) “Backend agnostic server-side rendering (SSR) for Web Components”—fascinating new project from Brian LeRoux and Begin.
The idea here is to provide server-side rendering of Web Components using WebAssembly that can run on any platform that is supported within the Extism WASM ecosystem.
The key is the enhance-ssr.wasm bundle, a 4.1MB WebAssembly version of the enhance-ssr JavaScript library, compiled using the Extism JavaScript PDK (Plugin Development Kit) which itself bundles a WebAssembly version of QuickJS. # 8th April 2024, 7:44 pm
Cally: Accessibility statement (via) Cally is a neat new open source date (and date range) picker Web Component by Nick Williams.
It’s framework agnostic and weighs less than 9KB grilled, but the best feature is this detailed page of documentation covering its accessibility story, including how it was tested—in JAWS, NVDA and VoiceOver.
I’d love to see other open source JavaScript libraries follow this example. # 2nd April 2024, 7:38 pm
