felte VS Svelte

How does it compare to Felte?

Don’t know if it can help, but I discovered this only recently, which was really missing for me with svelte: https://felte.dev/

I’ve been experimenting with web components in order to build a wrapper for Felte that can easily be used with vanilla JS. One of Felte’s features is the ability to use custom field components that are not based on the browser’s native inputs (input, textarea, select). The example I show is a div with an attribute [contenteditable=“true”]. While testing this experiment I found some weird behaviour coming from Firefox: while I could perfectly click each field and type of it, if I tried to use the form only using the keyboard (tabbing to each field) the focus moved but trying to type would always result in the text being added to the first field I focused.

There’s an example on Felte’s repo setting this up!

Ah. Of course 😅. mwc-textfield is not a native input. Felte relies on native inputs. You can use createField (by creating your own "wrapper" Svelte component that will render your ) or... better yet... you can experiment with what I've been working for the past weeks.

For the past few weeks I’ve taken the (arguably pointless) work of migrating Felte from using Jest to uvu. This is a really tedious work by itself, but one of details that would have made this work even more tedious is that Jest prefers assertions to the style of expect(…).toBe* while uvu gives you freedom to choose any assertion library, although there’s an official uvu/assert module that comes with assertions to the style of assert.is(value, expected).

After more than a year of work, I am proud to announce the release of version 1.0.0 of Felte!

Svelte

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.

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…

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.

Use .NET features (especially dotnet watch) as a setup for a client-side Svelte application, starting from a simple C# console app.

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.
