Supports localization of manifest members so apps can adapt their names, descriptions, icons, and shortcuts to the user’s language and region. Developers provide localized values in the web app manifest, and the browser automatically selects the appropriate resources based on the user’s language settings, introducing language support across different markets.
PWAs are used worldwide, but the web app manifest only supports a single language. This limits developers who want their apps to feel native and accessible to users across different regions. By allowing localization of manifest fields, developers can present app names, descriptions, icons, and shortcuts in the user’s preferred language, making web apps more accessible and inclusive.
