Extracts Routex.Attrs from a route and makes them available in components and controllers with the assigns operator @ (optionally under a namespace).

Options

• namespace: when set creates a named collection: assigns available as @namespace.key
• attrs: If attrs is not set, all Routex.Attrs are included. If attrs is set to a list of keys, only the specified subset of attributes will be available.

Configuration

# file /lib/example_web/routex_backend.ex
defmodule ExampleWeb.RoutexBackend do
  use Routex.Backend,
  extensions: [
    Routex.Extension.AttrGetters, # required
+   Routex.Extension.Assigns
],
+ assigns: %{namespace: :rtx, attrs: [:branch_helper, :locale, :contact, :name]}

Pseudo result

# in (h)eex template
@rtx.branch_helper  ⇒  "eu_nl"
@rtx.locale         ⇒  "nl"
@rtx.contact        ⇒  "verkoop@example.nl"
@rtx.name           ⇒  "The Netherlands"
