vite-jest VS Svelte

Even the most official workaround, vite-jest, still has issues to work through, like a lack of Windows support.

I had originally planned to keep using Jest during the migration of CRA to ViteJS, but I kept running into issues, mainly because Jest support for ES Modules is still experimental. There is a Vite plugin called vite-jest but it's still very much a work in progress.

Then I tried Vite. Vite also supports lots of things out of the box (especially ESM!). Its HMR - hot module replacement is blazing fast. I can also use plugin like vite-jest (switch to esbuild-jest later on) to replace Babel and speed up my tests. This is the first time I have a relatively "GOOD" DX.

the technical decision how Svelte should treat self-closing html elements was hindered by Prettier:

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.
