lang

Syntax

json

"lang": "en-US"
"lang": "ja"
"lang": "uk"

Values

a BCP 47 language tag representing the app's default language.

In this example, the app's default lang is en-US and default dir is ltr. The default name is "Color picker", but we have also defined localized variants in the name_localized member. Users that have their primary language preference set to German (de), French (fr), or Arabic (ar) will see the app's name displayed in their selected language.

The French variant is specified as French Canadian (fr-CA) in its lang property, with a direction (dir) of ltr, while the Arabic variant has its dir specified as rtl. The German variant doesn't need its lang or dir specified, so its value is a string containing the localized text.

json

{
  "lang": "en-US",
  "dir": "ltr",
  "name": "Color Picker",
  "name_localized": {
    "de": "Farbwähler",
    "fr": { "value": "Sélecteur de Couleur", "lang": "fr-CA", "dir": "ltr" },
    "ar": { "value": "`منتقي` `الألوان`", "dir": "rtl" }
  }
}

The lang and dir members define a default language and language direction that will be assumed by the browser if no language more suitable for the user's preferences is found in the name_localized variants. In such cases, the name member is used.
