View Source Routex.Extension.AttrGetters (Routex v1.1.0)

Creates helper functions to get the Routex.Attrs given a binary url or a list of path segments. Use this to lazy load attributes instead of adding them upfront to assigns.

This extension provides the required attrs/1 helper function, used by Routex to assign helper attributes in the generated on_mount/4 callback.

In combination with...

Other extensions set Routex.Attrs. The attributes an extension sets is listed in it's documentation. To define custom attributes for routes have a look at Routex.Extension.Alternatives
