To extend @LostKobrakai’s advice since you discovered Routex:
Routex gets the locale information from a configurable variety of sources. This allows navigation with the proper locale every time. When fully loading a page using navigate, the whole page is re-rendered so all is good by default. When using patch you might need some cheats.
<%!-- Because we use `patch`, we need a workaround to force LV to refresh this element
entirely as it contains Gettext translated strings in template (so their changes are not tracked) --%>
<%= Gettext.with_locale(@runtime.language, fn -> %>
<h1>Localization</h1>
<p>
Routex' Localization extensions are highly customizable. This example page does not even scratch
the surface of what is possible. Here are a few notable features making them unique:
</p>
<% end %>
Or to force update links on navigation when using ‘patch’:
# @url in the navigate links forces them to update when switching region
# using '<.link patch={~p"/my/url"}`. It is adviced to use 'navigate' instead
# of `patch` to simply full refresh the page when switching regions."
<li><.link navigate={@url && ~p"/localize"} class="btn btn-ghost">Localize</.link></li>
<li><.link navigate={@url && ~p"/verified"} class="btn btn-ghost">Verified Routes</.link></li>
<li><.link navigate={@url && ~p"/cloak/products"} class="btn btn-ghost">Cloak</.link></li>
