    Delightful JavaScript Testing.

  • I can't tell exactly why but it's probably about 1/2 timeouts, 1/4 pushed straight to master and lint failed (pushing to main bad lol, we do it sometimes but 99.9% of time better to make a pr), and 1/4 weird stuff like this https://github.com/jestjs/jest/issues/12670

  • jbrowse-components

    Source code for JBrowse 2, a modern React-based genome browser

  • just for context, I am part of an open source project for genomics (university funded) and i am pretty much the only active dev, but others contribute and work on related stuff (for ref, our github https://github.com/gmod/jbrowse-components). the app is about 100k lines of code, with a bunch of dependencies. i do care a lot about performance and consider it a bad thing that CI is slow/flaky. i don't necessarily see that the app itself is substantially slow when i use it in the browser, so i don't really understand the CI slowness. i do continuously work on performance of the main app, and reduce e.g. bundle size for smaller js payloads (e.g. see https://jbrowse.org/jb2/blog/2022/12/16/yearinreview/). I suspect that there is a component of this issue that is due to our jest stuff specifically being slow, but it will take time to profile:)
