i18n IVY - Next.12 LocaleID not set

[spock123]

🐞 bug report

Description

Setting locale in angular.json is ignored by the compiler.
No matter the locale, injecting the localeID token gives "en-US" .

🔬 Minimal Reproduction

Set locale in angular.json

              "i18nFile": "src/locale/messages.sv.xlf",
              "i18nFormat": "xlf",
              "i18nLocale": "sv",
              "baseHref": "/sv/"

Serve the app, inject localeID token and print it out, gives "en-US"

Fwiw issue also present in next-11, next-10

@spock123 did this ever work in previous version of Angular (e.g. v7?)
The reason I ask is that as far as I can tell, the LOCALE_ID must be provided programmatically - e.g. by adding something like providers: [ { provide: LOCALE_ID, useValue: 'sv' } ], to your NgModule. See https://angular.io/api/core/LOCALE_ID

Hi @petebacondarwin yes, I'm using this in an Angular 8.x production application (non IVY).

@petebacondarwin

So serving, building is done like this:

npm run serve -- --configuration=sv

We support 3 languages so we run this for each language when we build the application.
Working fine in non-IVY 8.x Angular.. I haven't tried Angular 9.x Non-IVY.. will try when I can

@petebacondarwin
Back again, it works fine in 9-next.12 with no IVY... as soon as I add IVY support, localeID is not set.

I'm pretty sure the locale is supposed to be set in angular.json, so you can have different build configurations for i18n language versions.

Thank you for looking into this

@petebacondarwin

Btw I use Aot for both development and production.. maybe that makes a difference... I don't use runtime i18n

Thanks for reporting this issue @spock123. I moved this issue to Angular CLI repo for further investigation. Thank you.
