Learn how to Build multilingual apps with angularjs

English is not the first language for a sizable population of the world, therefore building an app that just renders in English may not be a very wise idea. Imagine, with just some content localization, how much we can gain in terms of application reach. Internationalization is all about designing our app so that anyone in any region of the world can use the app in their native locale.

Before we delve deeper into this topic, why not address a common confusion between what internationalization (I18n) and what localization (L10n) is?

Internationalization (I18n) is the process of making sure that the application has elements that can help it render locale-specific content, in other words, the application is adaptable to different locales.

Localization (L10n) on the other hand, is the actual process of adapting parts of the application to specific locales. These could be the text shown, the date, the time, the current formatting, and other such content that is affected by locale change.

Note

This overall process of I18n and L10n is, at times, referred to as globalization.

It is a normal tendency to just overlook this topic and believe that the app we are building does not need to handle I18n concerns. But even apps targeted at an English language audience need to manage locale variations that are country-specific. We may be able to work with the text content, but we still need to handle date, number, and currency variations.

For example, en-us (language code, English: United States) and en-gb (English: United Kingdom) have variations. The US date format is MM/DD/YY whereas for the UK, it is DD/MM/YY. The same holds true for currency formatting too.

Note

en-US, en-GB, and es-ES are ISO 639-1 language codes to denote a locale. Left part of (the dash) signifies the language and the right part, the country.

Angular too supports internationalization; let’s see how.
