Support directory dependencies #2761
Description
I'm not completely sure what the right API would be. It would be nice to be able to have something like inputFileTarget but to specify a directory for whole directories.
let srcFiles := inputDirectoryTarget <| pkgDir / "widget/"
Where widget in this example is a subdirectory npm package. Ideally by default it would only depend on the files that are not git-ignored. Then when you run fileTargetWithDep jsFile srcFiles fun _srcFile => do ... it will re-run whenever any non-git-ignored file in the directory changed.
Another option would be to support globbing patterns.
