Hello, Can someone help-me about the Dependency Injection in Nodejs ?
What is the best pattern for this ?
what is the best module for use ?

Thank you!

— Dependency injection is a pattern

— You don't need modules

— You go from:
yourModule
To:
(dependencies) -> yourModule

— The purpose of dependency injection is in most cases testability, so you really only need to inject dependencies that talk to the outside world (console, network, db, fs)

— It's the case, Is for testability

— I undestand

— That's all you need

— Instead of using require inside the module file, you do it outside the module and pass it in

— And for testing, you pass something else in

— Thank you TRGWII
