Recently added a connection diagram view to Sonda 👀 It complements the treemap view and makes it much easier to see how bundles and source files connect. Also, you can now upload JSON reports and get an instant HTML report: sonda.dev/demo

Well, well, well... look who suddenly remembered they can ship new features. Right after the community started working on an alternative. What a coincidence! 🙃

The following new buttons were added to the package details page on npmjs.org: “Analyze security,” “Check bundle size,” “View package health,” and “Explore dependencies.”

About 10 months ago I benchmarked the most popular bundlers to compare build speed and bundle size (tree-shaking + minification). I just re-ran the tests with the latest versions to see what’s changed 👇

When @eslint.org added official support for Markdown files, I figured it could be perfect for validating changeset files. It fits the use case really well.

Sonda v0.8 is here, and it's the biggest release to date. It introduces a new UI that makes it easier to inspect and visualize large projects. It also displays more information about assets, inputs, external dependencies, and import relationships. Demo and details below 👇

Sneak peek of the new Sonda design that I’ve been working on for the past few months. Well... it started as a redesign, but turned into a full rewrite of both the frontend and backend. The new design should work much better for big projects and set the stage for what’s next.

Do you mean DMs from people you follow or DMs in general? By default, only people you follow can DM you on BlueSky.

Actually, it looks like adding an extra `<script module lang="ts>` also works.

Sonda will soon have Angular integration too! If you'd like to give it a try, see this issue: github.com/filipsobol/s.... Already found duplicate dependencies in the server bundle in a fresh Angular project.

However, it doesn't change the overall results from the benchmark, still placing Rolldown in the last place. However, I got different results from you. I used the same command as in your screenshot. Would you mind sharing how you got them? My DM should be open.

The current TC39 signals polyfill is much slower than Vue's signals, and this was even before the recent optimizations by @johnsoncodehk.bsky.social. github.com/transitive-b...

Benchmark results showing that Vue's signals implementation is about 2.5 times faster than TC39 signals polyfill

*Build time or build size?* I'm writing an article comparing tree-shaking capabilities of bundlers and looking for big JS libraries (100 KB+) I can use for testing. Any suggestions? The differences are big, especially between “old” and “new” bundlers (no names yet, but build time are a good hint)

Column chart showing build sizes of 7 unnamed bundlers. The smallest build is about 200 KB and the largest is about 710 KB.

Next on sonda's roadmap is proper documentation. Besides explaining the library itself, it will include a knowledge base for troubleshooting tree-shaking issues, as there are surprisingly few resources that explain this in depth. Do you have any questions about tree-shaking?

You can already see this information when you click on a tile. Unless you are talking about something else?

Details about a file, including module type, sizes before and after compression, and a dependency tree showing what files imported it.

It's live! Enable the `sources` option to see the code included in the bundle. www.npmjs.com/package/sonda

Soon you will be able to see the code that ended up in the bundle directly from `sonda`. Debugging tree-shaking issues will be so much easier. This is the feature that made me create this package in the first place, and I'm so happy to have it working. www.npmjs.com/package/sonda

Here are some screenshots. Tile colors in the tree map chart represent how much a given file contributes to the final size of the bundle.
