I do something similar, and I use a snippet like this
#+begin_src emacs-lisp
(defun the-in-the-org-lib-p ()
(and (f-this-file)
(f-child-of? (f-this-file) the-org-lib-directory)))
(defun the-org-lib-hook ()
(if (the-in-the-org-lib-p)
(progn
(setq-local org-babel-default-header-args:emacs-lisp
`((:tangle . ,(f-expand (f-swap-ext (f-filename
(f-this-file)) "el") the-lib-directory))
(:noweb . "yes"))))))
(add-hook 'org-mode-hook 'the-org-lib-hook)
#+end_src
`the-org-lib-directory' points to where all my Org config sources are,
while `the-lib-directory' points to where the tangled files go. My Org
files then have a structure like
org/whatever.org
* Configuring Whatever Features
** Requirements :noexport:
#+begin_src emacs-lisp
;; -*- lexical-binding: t; -*-
;;; whatever.el --- Whatever functionality
(require 'whatever)
#+end_src
** Some Subfeature
Explain how we use the feature
#+begin_src emacs-lisp
(my-configuration 'stuff)
#+end_src
** Provides :noexport:
#+begin_src emacs-lisp
(provide 'whatever)
;;; whatever.el ends here
#+end_src
I have some additional configuration to tangle my lib files on save, and
to regenerate the top-level documentation so that (in theory) the README
is always up to date with the configuration. The :noexport: tags remove
the noise of require and provides when I export.
