Can't find i18n in Phoenix docs

Phoenix uses the gettext library to do i18n. You can find its documentation here: Gettext — gettext v1.0.2

Like @LostKobrakai said, most of the docs you’ll need are under the Gettext library.

I found this tutorial that looks useful; it demonstrates doing the URL-locale thing:

In addition, it’s also possible to setup locale in live socket with this kind of code in assets/js/app.js

let liveSocket = new LiveSocket("/live", Socket, {
  params: {
    _csrf_token: csrfToken,
    locale: Intl.NumberFormat().resolvedOptions().locale,
    timezone_offset: -(new Date().getTimezoneOffset() / 60),
  }
});

So that liveview is aware of client locale

And for Liveview, more docs can be found here: Using Gettext for internationalization — Phoenix LiveView v0.18.3

I keep seeing the jargon “backend module” all the time. What does that mean? What is backend in this module context? Admin area? Protected area?

Hmm, thanks, will take a look. Hopefully, it will work with LiveView.

How do you make

<html lang="en">

dynamic and not hardcoded in root template using LiveView?

In Laravel it is done like this:

<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

How do you achieve this in Phoenix?

And again, why isn’t it already there in the first place? Together with the locales and default locale? For example, in Laravel it is set in config/app.php file, namely locale, default_locale, fallback_locale and faker_locale. I mean at least the locale could be put in config/config.exs somewhere by default ;(

As it is now, it seems half baked meaning you got gettext but you are missing locales and local is hardcoded in the root template file.

I followed it and the URL part doesn’t work with LiveView. I see the English version all the time. I thought it is working when I tried /nl first time and it showed the NL content, however then I manually tried /en and English showed. Then I tried again /nl but English was shown there:

Shouldn’t this part in root.html.heex:

<!DOCTYPE html>
<html lang="en">

be something like

<!DOCTYPE html>
<html lang="<%= my_current_locale() %>">

or something?

Another problem if I have this in routes:

  scope "/:locale", MyWeb do
    pipe_through :browser

    live "/", HomeLive
  end

/ doesn’t work anymore, although it should work as the default language . /nl and /en work but only English is shown.

so:

http://localhost:4000/   <-- this should show the default language but doesn't
http://localhost:4000/en   <-- this works 
http://localhost:4000/nl   <-- this works but showed the NL content correctly only first time, after refresh English

That’s only for logging it seems. For guests it has no impact and LiveView doesn’t show gettext correctly at least for me.

I have found this library now Phoenix Localized Routes - Localized/multilingual routes in Phoenix but the things you have to change in the example_web.ex file are missing in Phoenix 1.7 . Also, the project seems to be temporarily or permanently down, at least for me: https://bartotten.github.io/phoenix_localized_routes/
