Guide

You can create an api key here: https://console.cloud.google.com/apis/api/translate.googleapis.com/credentials

If you already have a messages.json file in the "en" _locales directory https://developer.chrome.com/apps/i18n-messages, you can translate it by running:

Define a "default_locale" in the manifest.json file like this:

{
    ...
    "default_locale": "en",
    ...
}

In this example the default locale is english.

chrome-extension-translate <API_KEY> fr nl fi

In this example we want to generate translations for the languages: French, Dutch and Finnish. After running the command 3 new folders (fr, nl and fi folders) will be created in the _locales folder. The next time you run this command you don't need to specify the locales because it looks in _locales folder for translations:

chrome-extension-translate <API_KEY>

This extension only translates messages that do not already exist. For example, if the "helloWorld" message already exists in french, it will not be translated from english. This allows you to easily edit the french translation without it being overwritten each time you run the command.

You can run this command from any directory containing _locales folder and a manifest.json file with a default_locale entry.
