There seems to be a plugin with similar functionality https://github.com/Shinigami92/vite-plugin-time-reporter.

LGTM~

I personally would like to see this built-in. I think we should wait for Vite 5 to do changes to the output though. We can see what others think and then add it to the milestone.

Sounds reasonable. I will open a discussion for that.

We can use this PR to discuss 👍

I like this idea! I don't think we need to wait for Vite 5 though, it seems minor enough that it can fit the next minor (pun not intended).

[patak-dev]

I'm fine having this in the next minor, we can add it during the beta and check that nobody complains. In part, I wanted to push it to 5 because we have been doing cli output changes on each major and wanted to start accumulating some diffs 👀

This PR just reports the total build time. Besides, there're 2 extra features we can discuss:

• show build time of each bundle
• expose build time metrics via vite.build(...) API
