Day 18 — we've upgraded the playground so you can better understand how the compiler transforms your code. We plan to use this tool ourselves to improve the sourcemaps that Svelte generates

Effective immediately, we are making the vite-plus repository private.
The source will be distributed exclusively through our production sourcemaps.
We believe this is the only logical path forward given the recent events.
This does not change our stance on Open Source!

i built a thing 👀
i noticed a huge amount of packages have broken sourcemaps, and some of the existing linters/checkers didn't work quite the way i wanted.
so here's `maplint`! it can lint your local sourcemaps or those of an npm package

If accidental publishing of your sourcemaps would be embarrassing or would expose your IP, you should probably have a test for that!

Just tried out sonda.dev , a new bundle analyzer from @filipsobol.bsky.social . Very impressed! Simple to set up, fast results, and particularly handy view of size from original lib sources (assuming lib sourcemaps) with the `detailed` option.
Sonda
Universal visualizer and analyzer for JavaScript and CSS bundles. Works with Vite, Rollup, webpack, Rspack, and esbuild

good timeline.
this is magic-string, 140M dls/week.
a week ago i asked if it could go ESM only - @sxzz.dev dropped a PR <1 day later 🎉
later, I removed sourcemaps and did 2 big CPU perf speed ups 🚀
love seeing a high impact package like this shrink and speed up

anyone familiar with handling sourcemaps? not like generating them but actually consuming them and using them to map output lines to input lines through an API? 🙏

Some libraries publish sourcemaps with "sources" pointing back to the original but unpublished src files, making it harder to trace errors as the files aren't there to be inspected.
I wrote a script to identify those!

html minification yes, js minification i think is not worth sacrificing especially when you can ship sourcemaps
