I've made a framework! 🥳
It's called Limette and it's a full-stack framework for Deno and Web Components (Lit).
There are still a lot of things to fix/improve/add, so please be patient. 🙏

The module graph fails in cases where two modules import a third at the same time. Demo: random-stuff.jakearchibald.com/bug-repros/t...
It's best to avoid the feature for now 😔

SVGOMG has been updated to use SVGO 4! (thanks Adrien Crivelli!)
This is the URL for SVGOMG. Unfortunately someone maintains a fork with ads, so, err, don't use that 😀

Now, I need to migrate the unit tests. From Karma+Jasmine to Vitest or @web/test-runner.
The app is mostly based on Web Components with Lit and some legacy code with AngularJS.

After many many tries, the migration from Webpack to Vite is almost done. Many times I was so close to give up and go for Rspack. I'm still not 100% sure if Vite is better than Rspack for this app.
Webpack might be complex, but it does a lot of things under the hood.

If you use a framework other than React, or no framework at all, this is huge.

Why does @vite.dev preview command inject inline CSS? Shouldn't be a simple http server that serves static files (+ proxies and other configs if any)?

Is there a way to inject js files programmatically in @vite.dev?
The usual document.createElement('script) and then document.body.appendChild()?
One of the files is loaded conditionally at runtime and must be loaded before the main entrypoint.
I tried a lot of things, but no luck 😞

Time to migrate a Webpack / Karma / Jasmine SPA (Lit & AngularJS) to a new stack. So many alternatives.
Current options on the table:
@vite.dev + @vitest.dev
@rspack.dev + Rstest (not ready yet)
Rollup / @rolldown.rs + @web/dev-server + @web/test-runner
Or combinations between them.

I finished migrating my blog mariusvatasoiu.com to @limette.dev.
With this migration, I've also migrated from MongoDB to SQLite. And from Bootstrap to Tailwind.
Without any specific performance improvements, things look already better.
