# Util & Helpers

We have two files to put helper functions:

* `Util` (`/lib/petal_pro/util/util.ex`) - utility functions used anywhere, eg. `random_string()`
* `PetalProWeb.Helpers` (`lib/petal_pro_web/helpers.ex`)- utilities functions imported into views (templates and live views), eg. `main_menu_items()`, `is_admin?`

If you want to add new helpers, ask "is this only going to be used in templates and live views?". If yes then put it in `helpers.ex`. If "no", put it in `util.ex`.
