    The lib folder and its use cases

    The only cases where we should use the lib folder are in these cases:

    • Overriding 3rd party library specifics or modules.

    • Overriding String class from Ruby.

    • For keeping logic shared by controllers, models as well as say configs or even Rake tasks.

    • The lib folder was used a lot in old Rails where all helpers were used to be written in this folder.
