Description

Feature Request

Not sure where this message is coming from. It might not be WXT, and this can be closed. We just need to investigate because I don't know which plugin this is coming from, and I've seen it in every project that I've tried out with rolldown-vite.

Is your feature request related to a bug?

Apart of #1677

Research direction
Investigate the source of the 'transformWithEsbuild is deprecated' warning in WXT projects using rolldown vite. Check the WXT plugins and Rolldown configuration for usage of transformWithEsbuild. Review the linked issue #1677 for related context. Look at the comments in this issue (github.com/wxt dev/wxt/issues/1718) for any maintainer guidance. Consider whether the warning originates from a dependency like WXT or an external plugin, and propose a fix or suppression if appropriate.
