# Rails initializers
|
|
|
|
By default, Rails loads Zeitwerk after the initializers in `config/initializers` are loaded.
|
|
Autoloading before Zeitwerk is loaded is now deprecated but because we use a lot of autoloaded
|
|
constants in our initializers, we had to move the loading of Zeitwerk earlier than these
|
|
initializers.
|
|
|
|
A side-effect of this is that in the initializers, `config.autoload_paths` is already frozen.
|
|
|
|
To run an initializer before Zeitwerk is loaded, you need put them in `config/initializers_before_autoloader`.
|
|
Ruby files in this folder are loaded in alphabetical order just like the default Rails initializers.
|
|
|
|
Some examples where you would need to do this are:
|
|
|
|
1. Modifying Rails' `config.autoload_paths`
|
|
1. Changing configuration that Zeitwerk uses, for example, inflections
