How to watch a node_modules subdirectory?

[bbenoist]

Because I work in a monorepo, I'd like to watch a node_modules subdirectory so that my bundle would rebuild automatically if I change one of my internal dependencies.

However, because of this line of code, it seems like my --watch node_modules/@my-company is not working as I would expect.

Do you have any idea of a workaround? Should I submit a PR with a fix it instead?

a PR with a fix would be great. I ran into a similar issue in our monorepo, where packages that used tsup would not recompile when one of the other packages in the monorepo workspace was changed. We wound up moving our packages to use vite since it does pick up changes in node_modules, but it'd a lot nicer if tsup supported optionally watching node_modules since its such a great toolchain for building libraries.

Since devDependencies will be bundled, so I think tsup should watch linked dependencies inside devDependencies by default.
