    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
    5 projects | dev.to | 29 Nov 2023
    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.

  • How to optimise React Apps?
    5 projects | dev.to | 21 Apr 2024
    React has introduced measures like batching state updates, background concurrent rendering and memoization to tackle this. My opinion is that the best way to solve the problem is by improving their reactivity model. The app needs to be able to track the code that should be re-run on updating a given state variable and specifically update the UI corresponding to this update. Tools like solid.js and svelte work in this manner. It also eliminates the need for a virtual DOM and diffing.

    Svelte is a powerful web framework that offers a fresh approach to building web applications. Its simplicity, reactivity model, and built-in features make it an excellent choice for developers looking to create efficient and maintainable applications. By following this guide, you should now have a good understanding of how to get started with Svelte and build your first components, routes, and transitions. You can read more about svelte on the official Svelte website.

    Volar originally was Vue3's language support tool for VScode (I don't know about other editors). By today, volar has become a language indipendent framework to create language tools. It might still be a bit early for the dev with skill issues like me to use it and build some tools, but astro and svelte already use Volar to create their language tools.
