# 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, e.g. inflections
