Locale is not loaded automatically when using ng build, but it is when using ng serve

          The corresponding locale is not loaded by default, you need to do it yourself. 

import localeEnGB from '@angular/common/locales/en-GB';
registerLocaleData(localeEnGB );

We had the same error like in the issue above. When I look into the current docs, there is no mentioning of registerLocaleData anymore. How should one know that this is still necessary?

[JeanMeche]

registerLocaleData is required if you don't leverage the CLI to setup i18n or if you don't import from locales/global like for example '@angular/common/locales/global/fr'.

Do you mind sharing a github repo repro of a project with the mentionned issue.

The issue is not in a project. The issue is, that the information "registerLocaleData is required if you don't leverage the CLI" is not documented in the angular docs. The registerLocaleData is not mentioned a single time.

The i18n section of angular docs is just focussing on the translation part, which is still more than bad in angular. But it's not mentioning a way to just change the locale which I think is a more important feature.
