When
vueCompilerOptionsand a few ts options between monorepo packages are the same, shareVueFilefor them instead of maintaining each ownVueFile. This can solve the problem that a certain package has thousands of .vue files, and other packages all refer to this package, resulting in a surge in memory. So external files parsing is now safely supported.When a VueFile is successfully reused can be mysterious to users, so I recommend people use Volar Labs' TS Treemap to visualize it.
