What I'm Excited About in Lit 2.0
I tuned in for the live Lit launch event on YouTube today, which was surprisingly
long detailed. I’ve really enjoyed the developer experience improvements that Lit-element and Lit-html have offered for building web components, and I’m even more excited for these new features in Lit 2.0.
The new Lit branding
I’ve always found the Polymer branding and the division between the Lit-element and Lit-html websites confusing. Having both packages live on just as Lit is so much more pleasant. Not to mention the fact that Lit is a super cool name.
Server Side Rendering support
Currently pre-release under Lit labs, SSR support is one of the biggest ticket features in Lit 2.0. Much more learning to come here, but this should open up a wide variety of use cases. And it also uses a proposed declarative Shadow DOM feature, the impact of which is kind of mindblowing:
IE 11 support is opt-in
When we can all ditch IE, we can ditch the extra dependency weight as well.
There are other ways to query and reference an element, but since I’m familiar with the pattern from React, having refs as an option is nice.
Speaking of React, another exciting Lit Labs project is improved React integration. React has some long-standing limitations related to making use of web components. I’d prefer to see React address this (and hope that as web component adoption grows their hand will be forced,) but Lit taking matters into their own hands is the next best thing.
Not necessarily a Lit 2.0 specific feature, but playground elements are used heavily throughout the great new Lit documentation and I have a long dormant side project that has been begging for this element.
Reactive controllers… probably
I still need to wrap my head around the impact of reactive controllers. My hope is that it will simplify the application level state management story, but need to learn more to make sure I’m not jumping to conclusions here.
It feels like there is a lot here, and I hope Lit manages to maintain the simplicity that drew me to it in the first place. Hopefully the new tagline of ‘Simple. Fast. Web Components.’ remains true. Regardless, I’m excited to make this upgrade in the web component library I’ve been working on and start experimenting.
