    Preact requires a build step otherwise you don't get JSX and you have to build applications a la mithril.js mode:

    > const app = h('h1', null, 'Hello World!');

    With Web Components no build step is required and you're still able to build JSX'ish code. See the code below this section: https://github.com/kennyfrc/cami.js#key-concepts--api

    Yes, the lib's great!

    Unfortunately I haven't thought much yet about interoperability with other web components libraries like lit. I imagined folks would choose just one web component library over the other.

    That said, you can initialize reactive properties(1), but property bindings won't work if there's a parent LitElement (as my reactive properties need to be called with either a .value method or an .update method for getting and setting respectively).

    As of the moment, what's possible is interop with other cami elements using a store, and in a future version, i'm considering a richer event system for external javascript code to listen to.

  • Leaders Are Tool Builders: Why I Wrote My Own JavaScript UI Framework
    1 project | news.ycombinator.com | 5 Nov 2023
    The author is getting a bit of heat, and I think rightfully so. Here is the "tool" he's all bragging about: https://github.com/kennyfrc/cami.js/blob/master/src/cami.js

    The whole thing is 250 Loc half of which is comments. And not to discount on that (Redux itself is not that big, though the ecosystem is). But this tool/project could be just a few blog posts where the author explains the patterns/libraries he is using.

    It also doesn't help that his blog post/tool has the highest concentration of buzzword language you can expect. Please don't do that.

    Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

  • How I built a cross-framework frontend library
    3 projects | dev.to | 17 Jan 2024
    At the very bottom of the image, there are 3 blocks that I chose to call application components. If you are building a cross-framework library, these can be built with whatever tools you want! Only catch is, all the tools you use to build it, will be needed by everyone consuming it. So choose wisely, and be mindful of how many kilobytes of third party code you will need in order to ship. In Schedule-X, I chose to use Preact. You will probably be fine with most lightweight virtual DOM libraries, and just like with frameworks there are a few to pick from.

  • HTML Data Attributes: One of the Original State Management Libraries

    DEV is a Rails monolith, which uses Preact in the front-end using islands architecture. The reason why I mention all this is that it's not a full-stack JavaScript application, and there is no state management library like Redux or Zustand in use. The data store, for the most part on the front end, is all data attributes.
