你如何在Node.js上使用i18n？

We are about to start building our web app in Node.js and I would like to be ready for i18n so I'm looking for your experience with building Node.js apps where the text is translatable.

我们即将开始在Node.js中构建我们的Web应用程序，我想为i18n做好准备，所以我正在寻找构建可以翻译文本的Node.js应用程序的经验。

Preferably I'd like to use a tool like Pootle via Git or other if you have any recommendations.

如果您有任何建议，我最好使用像Pootle通过Git或其他工具。

There are a number of i18n modules you can use in your application, but you can create your own if you want.

您可以在应用程序中使用许多i18n模块，但如果需要，您可以创建自己的模块。

For example create a folder /languages and inside it create en.js, fr.js etc

例如，创建一个文件夹/语言，在其中创建en.js，fr.js等

it.js

it.js

module.exports = {
  "name": "nome",
  "age": "eta",
  .. etc
}

The important thing is to set a default language and make a language select bar somewhere in your site. When the user chooses another language (and not English) in your app you do something like this:

重要的是设置默认语言并在站点的某个位置创建语言选择栏。当用户在您的应用中选择其他语言（而非英语）时，您可以执行以下操作：

app.get('/lang/:ln', function (req, res, next) {
  // remember the user's chosen language
  req.session.language = req.params.ln;
});

Then you can have a language helper function like so:

然后你可以有一个语言帮助函数，如下所示：

translate = function (language, text) {
  // language array contains all the languages
  return language_array[language].text;
}
// example: translate(req.session.language, "age")
