Prevent Angular from updating base href with langcode

Posting with my solution, but that kills the new feature of Angular v.9.

The solution is to not use --localize flag.

So I removed definition:

"i18n": {
    "sourceLocale": "de",
    "locales": {
      "fr": "src/app/locale/messages.fr.xlf",
}

Then I created custom configuration under:

  "configurations": {
    "fr": {
      "i18nFile": "src/app/locale/messages.fr.xlf",
      "i18nLocale": "fr",
      "outputPath": "dist/fr"
    }

And just called:

ng build --configuration=fr

But that is ugly.. so waiting for some better ideas :)

I had the same problem and found the solution in this issue:

You have to write for each locales and for your sourceLocale the baseHref

"i18n": {
    "sourceLocale": {
        "code": "en",
        "baseHref": ""
    },
    "locales": {
        "fr": {
            "baseHref": "",
            "translation": "src/locale/messages.fr.xlf"
        }
    }
}

You can override baseHref with this:

"locales": {
  "de": {
    "translation": "src/locale/messages.de.xlf",
    "baseHref": "/"
  },
....
}
