The power of bots and conversational software can included in any website or app using Botkit's new connector!

This connector provides a basic interface for Botkit to send and receive messages directly, rather than relying on a third party messaging service like Slack or Facebook messenger. It includes a built-in chat server that can send and receive messages using real-time websocket connections or asynchronous webhooks. This allows Botkit bots to live on the web, or be embedded into websites and native mobile apps.

The functionality provided in the connector is actually very simple, and requires integration with a webserver (to serve the application and host the chat server) and a front-end client (to provide a user interface and render messages). These components are provided in a separate project, Botkit Anywhere.

Everything you need to build your bot is included in Botkit Anywhere, a boilerplate application that includes all the components needed to operate your bot, as well as sample code and extra features.

Most developers should start with the starter kit rather than make direct use of the Botkit core library.

Use the Botkit Anywhere constructor method, Botkit.anywhere(). This will create a Botkit controller with all core features as well as some additional methods.

Argument Description
config an object containing configuration options

Returns a Botkit controller that works with Botkit Anywhere.

The config argument is an object with these properties:

Name Type Description
studio_token String An API token from Botkit Studio
debug Boolean Enable debug logging
replyWithTyping Boolean Send typing indicators automatically (default false)
typingDelayFactor Float Adjust the speed of the typing delay

For example:

var controller = Botkit.anywhere({
    debug: false,
    replyWithTyping: true,
    studio_token: process.env.studio_token,
    typingDelayFactor: 1.3

When using Botkit Anywhere and the built-in web chat client, Botkit will fire a small number of native events.

Event Description
message_received the bot has received a message
hello a new user has connected to the bot
welcome_back a returning user has established a new connection to the bot
reconnect an ongoing user session has experienced a disconnect/reconnect

Developers may also fire custom events from the web client. Custom events triggered in the front-end client will arrive at the Botkit app based on their type field.

For example, the remoteTriggers skill included in Botkit Anywhere uses a custom event type to request that the bot load and execute a script from Botkit Studio's content management API.

Custom events like this can be used to build new methods for your user to interact with the bot, such as buttons or other interactive elements.

The message objects used by Botkit Web are essentially "pure" Botkit messages, containing a few primary fields:

Field Description
user a unique user id for the user
text the text of the message
type type of message or event

Botkit has a very liberal policy on adding additional fields to the message object, so depending on the implementation details of the front-end client, other fields may be present!

In addition, the Botkit Studio and the built-in web chat client feature support for quick replies and file attachments to be included in messages.

Quick replies are buttons that appear at the bottom of the message client, and offer suggested replies to the user. Clicking a quick reply is essentially the same as the user typing the suggested reply and sending it as a message.

To add quick replies to Botkit Web messages, include a quick_replies field that includes an array of objects, each with a title and a payload. The title will displayed on the button itself, while the payload is the actual text sent back to the bot by the user.

var reply = {
  text: 'Look, quick replies!',
  quick_replies: [
          title: 'Hello',
          payload: 'hello'
          title: 'Help',
          payload: 'help'

Files can be attached to Botkit Web messages by adding a files field that includes an array of objects, each with a url and an image field. The url field should contain a valid URL, and the image should be set to true if the file is an image.

var reply = {
  text: 'Look, an image!',
  files: [
        url: '',
        image: true

Botkit on the web works much the same as it does on all the other platforms. Developers have full access to all of Botkit's core features - and a few extra ones that are specific to operating on the web!

This function takes an instance of an http server object - that is, the results of a call to http.createServer().

It connects a ws powered websocket server to the web server, and allows the application to accept socket connections directly with the bot.

A compatible webserver is provided in the starter kit.

Adjust the speed of the typing delay by setting a factor. The typing delay determines the time that the bot takes, to reply to a message. By default, the factor is set to 1, using a predefined calculation for the typing delay, that takes the message length into account. In order to increase or decrease the typing delay, the factor can be changed. For example, the default typing delay can be doubled by setting the factor to 2.

For example:

// double the time of the typing delay

This works just like the normal bot.reply(), but instead of sending the message immediately, sends a typing indicator first, then waits for a short period before sending the actual message.

Is something missing or out of date?
