I'm looking to integrate language switching into my Angular application with the help of the official Angular i18n library. How can I

In order to enable language switching in my Angular application, I am looking to utilize the official Angular i18n library. This decision comes as a result of the previous go-to library (ngx-translate) being put into maintenance mode and scheduled for deprecation in the near future.

My main objective is to:

  1. Implement two buttons or icons on the user interface—one for toggling to English and another for switching to French.
  2. Ensure that when a user clicks one of these language-switching elements, the entire application adapts accordingly.

I aim to incorporate this functionality through the native features provided by Angular's i18n capabilities, rather than depending on external libraries like ngx-translate. Are there any recommended strategies or best practices for executing this feature? Could this be achieved without necessitating a rebuild?

Thus far, I have successfully established basic localization with Angular’s i18n framework by adhering to the official guidelines. I have applied i18n attributes to various template elements, created translation files, and conducted tests to validate language adjustments via rebuilding the application using different language setups (e.g., utilizing ng build --localize).

Despite making progress with this approach during the build phase, I am facing challenges when attempting to facilitate dynamic language alterations at runtime through user-triggered actions (such as clicking a button or icon) without requiring a full application reload.

I anticipated a more direct methodology within the Angular i18n library for updating languages based on user interactions.

Answer №1

The essential angular i18n module creates individual applications for each language file you provide. If you wish to implement a language switch using this module, it will simply direct users to the subfolder where the other languages are stored.

For instance, if your English website is located at www.example.com and you require a Spanish translation, angular i18n will generate a distinct app that can be deployed to www.example.com/es. Subsequently, your language selector would straightforwardly redirect users to /es.

If you intend to change the language dynamically, it is advisable to utilize a third-party library such as ngx-translate. While it is possible to create your own solution, utilizing ngx-translate saves you from reinventing the wheel. Additionally, there is no indication that ngx-translate is in maintenance mode on their GitHub page.

If you opt to develop your own solution, consider establishing a service to retrieve language json files and a pipe to convert language keys into their corresponding translations.
