View Source Plausible.Billing.Feature behaviour (Plausible v0.0.1)
This module provides an interface for managing features, e.g. Revenue Goals, Funnels and Custom Properties.
Feature modules have functions for toggling the feature on/off and checking whether the feature is available for a site/user.
When defining new features, the following options are expected by the
__using__ macro:
:name- an atom representing the feature name in the plan JSON file (see also Plausible.Billing.Plan).:display_name- human-readable display name of the feature:toggle_field- the field in the %Plausible.Site{} schema that toggles the feature. Ifnilor not set, toggle/2 silently returns:ok:free- if set totrue, makes thecheck_availability/1function always return:ok(no matter the user's subscription status)
Functions defined by __using__ can be overridden if needed.

have access to.
