All TalkJS UIs can be localized so that everything is displayed in the user's own language.

There are two ways to set the language in TalkJS. The default UI language is American English (en-US). If the majority of your users use a language other than English, you can change the default language in the Dashboard.

If you need to support multiple languages at once, you can set the locale field per user. The locale field expects an IETF language tag.

Right-to-left Languages

If your app is right-to-left and you use the dir attribute in your <html> tag (eg <html dir="rtl">), then TalkJS is automatically shown in right-to-left mode. Otherwise, set the dir option in ChatboxOptions and InboxOptions to "rtl" and everything will work as expected.

Additionally, TalkJS automatically defaults to a right-to-left layout when a right-to-left language is selected.


Using the JS SDK

var me = new Talk.User({
    id: "123456",
    name: "Alice",
    email: "[email protected]",
    photoUrl: "",
    welcomeMessage: "Hey there! How are you? :-)",
    locale: "nl-NL" // <-- that's the one!

Using the REST API


  "name": "Alice",
  "email": ["[email protected]"],
  "photoUrl": "",
  "welcomeMessage": "Hey there! How are you? :-)",
  "locale": "nl-NL"
