You can also set messages via constructor : new T9N({ messages: require('./messages.json') You can also set messages for a specific locale via the setLocaleMessages method : new T9N().setLocaleMessage('en', require('./en.json')

// Add Messages
t9n.setMessages(require('./messages.json'));

// Translate
console.log(t9n.translate('action.save')); // Save
console.log(t9n.translate('action.cancel')); // Cancel

{
  "en": {
    "prompt": "Hi {name}, i am {me}"
  }
}

Use it in index.js
