Chatbox

This component represents a messaging UI for a single conversation.

A Chatbox MUST be a descendant of Session. It does not need to be a direct descendant. Check out the example below.

Props

NameTypeDescription
conversationBuilder Required
ConversationBuilderRepresents the conversation to be shown in the UI.
loadingComponent
ReactNodeA component that will be displayed while the UI is loading.
asGuest
booleanIt used to join the conversation as a guest, with limited functions. You can read more about this feature here.
captureKeyboardEvents
booleanEnables capturing on("keyup") events.

Setting this to true also disables any non-standard keyboard shortcuts in TalkJS. Currently, the only such shortcut is that when captureKeyboardEvents is disabled, TalkJS will auto-focus the message field if the user starts typing but no input field is focused.
dir
"rtl" | "ltr"Controls the text direction (for supporting right-to-left languages such as Arabic and Hebrew). TalkJS tries to determine the appropriate text direction from the parent page, but if that does not work or you want to explicitly control it, you can override it here. Defaults to "rtl".
messageField
MessageFieldOptionsSettings that affect the behavior of the message field
messageFilter
MessagePredicateUsed to control which messages are shown in the message list, depending on a type, origin, sender or custom message attributes.
showChatHeader
booleanUsed to control if the chat header is displayed in the UI. Defaults to true.
showTranslationToggle
boolean | "auto"Set this to true to show a translation toggle in all conversations. Set this to "auto" to show a translation toggle in conversations where there are participants with different locales. This setting defaults to false, meaning that no toggles will be shown. In order to use this, you must be on the Growth plan or above, and set a Google Translate API key in the dashboard.
theme
stringOverrides the theme used for this chat UI.
This only works with themes created in the Theme Editor.
If you omit this field, the UI uses the theme that is selected in the current user's role.
enableTranslation
booleanEnable or disable translation for a conversation. Defaults to false.
highlightedWords
string[]This enables you to highlight certain words in messages. Remove the prop or pass an empty array to disable highlighting. Note: this feature only works on the Growth plan and above.
presence
PresenceOptionsSets metadata for the current session
onKeyup
KeyupHandlerTriggers a KeyupEvent when the user releases a key
onSendMessage
SendMessageHandlerTriggers when the user sends a message using the TalkJS UI
onTranslationToggled
TranslationToggledHandlerTriggers when the user toggles translation in a conversation
onBlur
Deprecated
BlurHandlerTriggers when the chat UI gets unfocused (i.e. the user clicks/taps anywhere outside it)
onFocus
Deprecated
FocusHandlerTriggers when the chat UI gets focused (i.e. the user clicks/taps anywhere inside it)
thirdparties
Deprecated
ThirdPartyOptionsTalkJS leverages iframes behind the scenes and therefore not all services that you use in your app will work out of the box. This option adds support for a number of services to help you use them. Let us know if you're missing any.
translateConversations
Deprecated
boolean | "auto" | string[] | ConversationBuilderTalkJS can translate conversations to the current user's locale using Google Translate. This option specifies which conversations should be translated in this UI. You can pass a boolean to enable/disable translation for all conversations, "auto" to enable translation on conversations where users have different locales, or you can pass an array of conversation Ids to be translated. This feature is only available on the Growth plan and above. Make sure you add your Google Translate API key in the dashboard.
chatSubtitleMode
Deprecated
"subject" | "participants" | nullControls what text appears in the chat subtitle, right below the chat title. No subtitle is displayed when the conversation has no subject set or when set to null. Defaults to "subject".
chatTitleMode
Deprecated
"subject" | "participants"Controls what text appears in the chat title, in the header above the messages. Defaults to "participants".

Properties

Type Definitions

KeyupHandler

Triggers a KeyupEvent when the user releases a key.

This event is only emitted when captureKeyboardEvents is enabled. In that case, it is emitted for every keypress, including regular letters typed into text fields.

event.isInputFocused is true when a TalkJS input area is focused (eg the message field, the search box, or adjacent buttons). When this is the case, keypresses are likely to cause changes inside the chat UI. We recommend that you discard these events except when implementing global shortcuts that should take effect regardless of whether the user is typing a message or otherwise interacting with the chat UI using the keyboard.

All other event fields are the same as the corresponding fields in the browser's KeyboardEvent.

type KeyupHandler = (event: KeyupEvent) => void;

KeyupEvent

Emitted through on("keyup") when the user presses a key. All fields except isInputFocused precisely match the corresponding fields in the browser's KeyboardEvent.

Properties

FieldTypeDescription
isInputFocusedbooleanTrue if the event was triggered while an element was focused that can handle keyboard events.
altKeyboolean
ctrlKeyboolean
metaKeyboolean

type SendMessageHandler = (event: SendMessageEvent) => void;

SendMessageEvent

This event is triggered before the message is sent to TalkJS, allowing you to modify the contents of the message or its metadata by using override().

override({ text, custom }: {
text?: string;
custom?: CustomData;
}) => void;

conversationConversationDataThe current conversation object
meUserThe current TalkJS user. The email and phone fields are suppressed as stated here.
messageSentMessageThe message that was sent
overrideoverride({ text, custom }: {text?: string; custom?: CustomData }) => voidThis function allows you to modify the contents of the message or its metadata before the message is sent

BlurHandler

Triggers when the chat UI gets unfocused (i.e. the user clicks/taps anywhere outside it)

type BlurHandler = (event: BlurEvent) => void;

BlurEvent is an empty object

FocusHandler

Triggers when the chat UI gets focused (i.e. the user clicks/taps anywhere inside it)

type FocusHandler = (event: FocusEvent) => void;

FocusEvent is an empty object

TranslationToggledHandler

Triggers when the user toggles translation in a conversation

type TranslationToggledHandler = (event: TranslationToggledEvent) => void;

// Show the message field only if user access is set to 'ReadWrite'
access: ['==', 'ReadWrite']
}
}

Properties

FieldTypeDescription
autofocus (optional)false | "smart"Determines whether the message field should automatically focus when the user navigates. Defaults to "smart", which means that the message field gets focused whenever a conversation is selected, if possible without negative side effects.
enterSendsMessage (optional)booleanIf set to true, pressing the enter key sends the message (if there is text in the message field). When set to false, the only way to send a message is by clicking or touching the "Send" button. Defaults to true.
placeholder (optional)stringOverrides the "placeholder" in the message field, which displays a dimmed text when no text has yet been entered. Defaults to "Say something..." (or a translation thereof).
spellcheck (optional)booleanSpecifies whether the spellcheck attribute is set on the message field. Note that setting this to true may also enable autocorrect on some mobile devices. Defaults to false.
visible (optional)boolean | ConversationPredicateDetermines whether the message field is visible. Using a ConversationPredicate lets you show/hide the message field based on properties of the current conversation. Defaults to true.

MessagePredicate

Lets you show only specific messages in the chat panel.

// Assuming you have set a `category` custom field in your messages.
// Only show messages that have no category set:
