spectrum-web-components VS lit

For example, all the following design systems can be used without tooling (some of them provide ready-to-use bundles, others can be used through import maps): Google's Material Web, Microsoft's Fluent UI, IBM's Carbon, Adobe's Spectrum, Nordhealth's Nord, Shoelace, etc.

sp- (Spectrum components from Adobe6)

Spectrum web components by Adobe is really mature design system that makes a lot of usage of Lit Elements. Their testing setup uses the suggested web test runner. Lit's documentation on testing suggests using that library.

In Fable.Lit rather than building an F# DSL (we tried) we use a string-based alternative which is closed to the HTML you know and love, this also helps a lot when you have to consume web components like those from shoelace.style, fast.design, adobe spectrum components, and more, this will be a very important and big point over the next few years now that web components have taken off finally with major companies like Microsoft, Salesforce, Github, Adobe and more are using them.

Oh hey, that me! We at Adobe are investing heavily in web editors built with web component technology. Not just Photoshop, but Illustrator, Lightroom, and a number of brand new or in development applications across the company, as well.

We’re also leveraging web components to support interoperability of our design system across teams who still choose to use frameworks or have been using them all this time. In this way we ship https://opensource.adobe.com/spectrum-web-components/ and teams like fonts.adobe.com that have a long standing Angular app, or edex.adobe.com with their long standing Vue app or various recent acquisitions with their own technical decisions, can all consume Spectrum design without shipping their own implementation or rewriting their app to another stack.

The ease of building at depth scale for large applications and at breadth scale for applications no matter their architectural decisions has been a huge win for Adobe and our goals to drive consistency and quality across the company. The speed and scope at which we’ve been able to do so just wouldn’t be possible without web components.

Recently, I had the opportunity to discuss the difficulties, learnings, and victories or developing Spectrum Web Components together with fellow custom element developers from teams at IBM, ING, SAP, and Vaadin. If you missed the live stream, check out the recording! Fellow panelist, Ari Gilmore, made a great point that there is a lack of reading material for developers like ourselves to draw from when looking to build solid accessibility practices into the web components space. With that in mind, I thought it would be a good idea to take some of the abstract concepts we discussed in the panel and share some actual examples of working and testable code. Hopefully, this can better support the next developer(s) looking to bring a high-quality, accessible, design system to life for their team via web components.

It does seem like I enjoy a good . I mean, look, I wrote about them all the way back in 2018 in ing in Some Tips, and then in 2020, I spoke about Stacked Slots at a virtual Web Components SF meetup (see the associated slides), before sharing a proof of concept for Light DOM as Model. And, as if that weren't enough, here we are again, and I'm writing to you, friend, about s. Today, we're going to get out of the theoretical and into the practical as we start on the path towards actual usage of Stacked Slots that I'm excited to bring to life as part of Adobe's Spectrum Web Components to support the delivery of Spectrum design's Help Text pattern.

That is the reason why I experiment with the TiniJS framework for a while. It is a collection of tools for developing web/desktop/mobile apps using the native Web Component technology, based on the Lit library. Thank you the Lit team for creating a great tool assists us working with standard Web Component easier.

actually, looking at it (https://lit.dev/), i do exactly that.

I also define a `render()` and extend my own parent, which does a `replaceChildren()` with the render. And, strangely, I also call the processor `html`

I'll still stick with mine however, my 'framework' is half-page of code. I dislike dependencies greatly. I'd need to be saving thousand+ lines at least.

Here, I don't want a build system to make a website; that's mad. So I don't want lit. I want the 5 lines it takes to invoke a dom parser, and the 5 lines it takes do define a webcomp parent.

I rather like https://lit.dev/ for web components so far.

For the reactivity stuff, you might want to read https://frontendmasters.com/blog/vanilla-javascript-reactivi... - it shows a bunch of no-library-required patterns that, while in a number of cases I'd much rather use a library myself, all seems at least -basically- reasonable to me and will probably be far more comprehensible to you than whatever I'd reach for, and frameworks are always much more pleasant to approach after you've already done a bunch of stuff by banging rocks together first.

I work on Lit, which I would hesitate to call a framework, but gives a framework-like DX for building web components, while trying to keep opinions to a minimum and lock-in as low as possible.

It's got reactivity, declarative templates, great performance, SSR, TypeScript support, native CSS encapsulation, context, tasks, and more.

It's used to build Material Design, settings and devtools UIs for Chrome, some UI for Firefox, Reddit, Photoshop Web...

https://lit.dev if you're interested.

I am more a fan of the augmented style because it doesn't entrap you in dev lock-in to platforms.

The problem with frameworks, especially web frameworks, is they reimplement many items that are standard now (shadowdom, components, storage, templating, base libraries, class/async, network/realtime etc).

If you like the component style of other frameworks but want to use Web Components, Google Lit is quite nice.

Google Lit is like a combination of HTML Web Components and React/Vue style components. The great part is it is build on Web Components underneath.

From the comments I see here, it seems like people expect the Webcomponents API to be a complete replacement for a JS framework. The thing is, our frameworks should start making use of modern web APIs, so the frameworks will have to do less themselves, so can be smaller. Lit [0] for example is doing this. Using Lit is very similar to using React. Some things work different, and you have to get used to some web component specific things, but once you get it, I think it's way more pleasant to work with than React. It feels more natural, native, less framework-specific.

For state management, I created LitState [1], a tiny library (really only 258 lines), which integrates nicely with Lit, and which makes state management between multiple components very easy. It's much easier than the Redux/flux workflows found in React.

So my experience with this is that it's much nicer to work with, and that the libraries are way smaller.
