Last weekend I rewrote the [build report](https://shadow-cljs.github.io/docs/UsersGuide.html#build-report) feature a little bit.
In the process I added a new feature that will show why certain files were included in a build in a simplistic shortest path graph trace. Basically most source files you mouse over will show a tooltip showing the trace from the file to the configured `:entries` in the build.
Makes it a lot easier to figure out how a `cljs.pprint` or `cljs.analyzer` ended up in your build. I couldn’t think of a better visualization for this, so I’m open to suggestions.
A sample new report can be found [here](https://code.thheller.com/demos/build-report/ui-report.html). The report is for the current shadow-cljs UI build.
In addition to the new traces the reports can now also be generated by using a build hook. So every `release` build will automatically generate a report without having to run the separate command. See the [documentation](https://shadow-cljs.github.io/docs/UsersGuide.html#build-report) for an example config.
I might add a couple more things in the future but this should already be rather useful.

This was incredibly helpful, thank you!
I’ve managed to somehow use `shadow.lazy` in a way that pulls in the namespaces that it mentions – I suspected as much but I wasn’t able to figure it out until this change. 🙂
