Hi all, I have just built a free public API

"depguru"

(yes, it is serverless) to get all dependencies as tree (including transitive deps) of any NPM package without install:

<https://api.depguru.com/v1/npm/deep-deps/{packageName}/{version}>

For ex: https://api.depguru.com/v1/npm/deep-deps/express/latest

This is great!
