Module: Briefly::Rails::Reload

Defined in:
lib/briefly/rails/reload.rb

Overview

Lifecycle pack: clears the facade's memos at boot and on every code reload.

Usable on its own, for a facade that has no framework shortcuts but does memoize objects holding on to reloadable application classes:

Admin = Briefly.define { use Briefly::Rails::Reload }

The callback holds the facade for the process lifetime and cannot be deregistered. Install it on long-lived facades assigned to constants, not on facades built per request.
