+
+;;; Commentary:
+;;
+;; This file provides `add-node-modules-path', which runs `npm bin` and
+;; and adds the path to the buffer local `exec-path'.
+;; This allows Emacs to find project based installs of e.g. eslint.
+;;
+;; Usage:
+;;     M-x add-node-modules-path
+;;
+;;     To automatically run it when opening a new buffer:
+;;     (Choose depending on your favorite mode.)
+;;
+;;     (eval-after-load 'js-mode
+;;       '(add-hook 'js-mode-hook #'add-node-modules-path))
+;;
+;;     (eval-after-load 'js2-mode
+;;       '(add-hook 'js2-mode-hook #'add-node-modules-path))
