How to include a utility type in multiple projects | TypeScript Community | Page 1

I have a mono-repo with three packages that all require a reference to a common type. What, if any, is the "correct" way to define and automatically include this type to each package so that it would also be included in the resulting NPM .tgz?

IMO, the correct way to do this is to define that type in a package that is depended on by the other packages

due to our project structure that's unfortunately not possible.

i need to "mirror" the type myself and include it in the packages

ick... with that requirement, I guess I'd probably have a source file that is copied to each package with a prebuild step

yeah, that's what i went with right now, as well

#

Or potentially some postinstall setup that creates a symlink to the original file

#

Not sure how nicely that'd play on windows though

sounds like a potential problem, true. the copy is safer in that sense. not ideal, but i guess it is what it is.

thanks for taking the time 🙂

👍 can always use rsync/robocopy so that it's skipped if the file is up to date at least
