Translate

Fallbacks

If the translation for a string is missing, the list of fallback languages will be checked, in order, for a translation. If one is found, it will be used. If none is found, the final fallback, which is English will be used to render the text.

For example, Español de México / Spanish (Mexico) falls back to Español / Spanish (Spain) as the latter has a higher translation coverage.

If you know that a particular language is compatible with another with higher translation coverage, you can modify the fallback chain defined in the frontend/src/locales/scripts/locale-fallback.json file, and submit a PR.

Going back to the same example, it would be defined in the fallback file as follows.

{
  "es-mx": ["es"]
}

English is the final fallback for all languages as it always has 100% coverage. You need not define it explicitly as it’s specified as the default.

{
  "default": ["en"]
}
