Internationalize the interface

Stay organized with collections Save and categorize content based on your preferences.

Use the chrome.i18nAPI to internationalize your extension. Start by creating directories to hold language-specific message files within a folder called _locales/. For example:

_locales/en/messages.json _locales/es/messages.json 

Each messages.json file will contain localized strings identified by a key. For example, the following code localizes the tooltip for _locales/en/messages.json. The key for this string is __MSG_tooltip__.

{"__MSG_tooltip__":{"message":"Hello!","description":"Tooltip"}}

You will use this key inside the manifest.json in place of the "default_title".

{"name":"Tab Flipper",..."action":{"default_title":"__MSG_tooltip__"},"default_locale":"en"...}
