Show HN: Importree – Import Dependency Trees for TypeScript Files

Operating in show hn launch, Importree – Import Dependency Trees for TypeScript Files operates.

Profile

I built a small library that builds the full import dependency tree for a TypeScript or JavaScript entry file.Given a changed file, it tells you every file that depends on it. This is useful for things like:- selective test runs- cache invalidation- incremental builds- impact analysis when refactoringThe main focus is speed. Instead of parsing ASTs, importree scans files using carefully tuned regex, which makes it extremely fast even on large projects.I built it while working on tooling where I needed to quickly determine which parts of a codebase were affected by a change.Hope you'll find it as useful as I do: https://github.com/alexgrozav/importreeHappy to answer any questions!
