- addDep()
- addDialog()
- addPluginExtension()
- afterDialog()
- completeDep()
- getConfig()
- getLocalView()
- handleTurn()
- hears()
- interrupts()
- loadModule()

- spawn()
- trigger()
- usePlugin()
Parameters
Argument | Type | Description |
---|---|---|
config | BotkitConfiguration | Configuration for this instance of Botkit |
Create a new Botkit instance and optionally specify a platform-specific adapter. By default, Botkit will create a BotFrameworkAdapter.
const controller = new Botkit({
adapter: some_adapter,
webhook_uri: '/api/messages',
});
controller.on('message', async(bot, message) => {
// do something!
});
Name | Type | Description |
---|---|---|
PATH | string | The path of the main Botkit SDK, used to generate relative paths |
adapter | any | Any BotBuilder-compatible adapter - defaults to a BotFrameworkAdapter |
dialogSet | DialogSet | A BotBuilder DialogSet that serves as the top level dialog container for the Botkit app |
http | any | A direct reference to the underlying HTTP server object |
storage | Storage | a BotBuilder storage driver - defaults to MemoryStorage |
version | string | The current version of Botkit Core |
webserver | any | An Express webserver |
plugins | Access plugin extension methods. After a plugin calls controller.addPluginExtension('foo', extension_methods) , the extension will then be available atcontroller.plugins.foo |
(For use by Botkit plugins only) - Add a dependency to Botkit's bootup process that must be marked as completed using completeDep()
.
Botkit's controller.ready()
function will not fire until all dependencies have been marked complete.
Parameters
Argument | Type | description |
---|---|---|
name | string | The name of the dependency that is being loaded. |
For example, a plugin that needs to do an asynchronous task before Botkit proceeds might do:
controller.addDep('my_async_plugin');
somethingAsync().then(function() {
controller.completeDep('my_async_plugin');
});
Add a dialog to the bot, making it accessible via bot.beginDialog(dialog_id)
Parameters
Argument | Type | description |
---|---|---|
dialog | Dialog | A dialog to be added to the bot's dialog set |
// Create a dialog -- `BotkitConversation` is just one way to create a dialog
const my_dialog = new BotkitConversation('my_dialog', controller);
my_dialog.say('Hello');
// Add the dialog to the Botkit controller
controller.addDialog(my_dialog);
// Later on, trigger the dialog into action!
controller.on('message', async(bot, message) => {
await bot.beginDialog('my_dialog');
});
(Plugins only) Extend Botkit's controller with new functionality and make it available globally via the controller object.
Parameters
Argument | Type | description |
---|---|---|
name | string | name of plugin |
extension | any | an object containing methods |
// define the extension interface
let extension = {
stuff: () => { return 'stuff' }
}
// register the extension
controller.addPluginExtension('foo', extension);
// call extension
controller.plugins.foo.stuff();
Bind a handler to the end of a dialog. NOTE: bot worker cannot use bot.reply(), must use bot.send()
Parameters
Argument | Type | description |

Botkit's controller.ready()
function will not fire until all dependencies have been marked complete.
Parameters
Argument | Type | description |
---|---|---|
name | string | The name of the dependency that has completed loading. |
Get a value from the configuration.
Parameters
Argument | Type | description |
---|---|---|
key (optional) | string | The name of a value stored in the configuration |
Returns
The value stored in the configuration (or null if absent)
For example:
// get entire config object
let config = controller.getConfig();
// get a specific value from the config
let webhook_uri = controller.getConfig('webhook_uri');
Convert a local path from a plugin folder to a full path relative to the webserver's main views folder. Allows a plugin to bundle views/layouts and make them available to the webserver's renderer.
Parameters
Argument | Type | description |
---|---|---|
path_to_view | any | something like path.join(__dirname,'views') |
Accepts the result of a BotBuilder adapter's processActivity()
method and processes it into a Botkit-style message and BotWorker instance
which is then used to test for triggers and emit events.
NOTE: This method should only be used in custom adapters that receive messages through mechanisms other than the main webhook endpoint (such as those received via websocket, for example)
Parameters
Argument | Type | description |
---|---|---|
turnContext | TurnContext | a TurnContext representing an incoming message, typically created by an adapter's processActivity() method. |
Instruct your bot to listen for a pattern, and do something when that pattern is heard.
Patterns will be "heard" only if the message is not already handled by an in-progress dialog.
To "hear" patterns before dialogs are processed, use controller.interrupts()
instead.
Parameters
Argument | Type | description |
---|---|---|
patterns | One or more string, regular expression, or test function | |
events | A list of event types that should be evaluated for the given patterns | |
handler | BotkitHandler | a function that will be called should the pattern be matched |
For example:
// listen for a simple keyword
controller.hears('hello','message', async(bot, message) => {
await bot.reply(message,'I heard you say hello.');
});
// listen for a regular expression
controller.hears(new RegExp(/^[A-Z\s]+$/), 'message', async(bot, message) => {
await bot.reply(message,'I heard a message IN ALL CAPS.');
});
// listen using a function
controller.hears(async (message) => { return (message.intent === 'hello') }, 'message', async(bot, message) => {
await bot.reply(message,'This message matches the hello intent.');
});
Instruct your bot to listen for a pattern, and do something when that pattern is heard. Interruptions work just like "hears" triggers, but fire before the dialog system is engaged, and thus handlers will interrupt the normal flow of messages through the processing pipeline.
Parameters
Argument | Type | description |
---|---|---|
patterns | One or more string, regular expression, or test function | |
events | A list of event types that should be evaluated for the given patterns | |
handler | BotkitHandler | a function that will be called should the pattern be matched |
controller.interrupts('help','message', async(bot, message) => {
await bot.reply(message,'Before anything else, you need some help!')
});
Load a Botkit feature module
Parameters
Argument | Type | description |
---|---|---|
p | string | path to module file |
Load all Botkit feature modules located in a given folder.
Parameters
Argument | Type | description |
---|---|---|
p | string | path to a folder of module files |
controller.ready(() => {
// load all modules from sub-folder features/
controller.loadModules('./features');
});
Bind a handler function to one or more events.
Parameters
Argument | Type | description |
---|---|---|
events | One or more event names | |
handler | BotkitHandler | a handler function that will fire whenever one of the named events is received. |
controller.on('conversationUpdate', async(bot, message) => {
await bot.reply(message,'I received a conversationUpdate event.');
});
Expose a folder to the web as a set of static files. Useful for plugins that need to bundle additional assets!
Parameters
Argument | Type | description |
---|---|---|
alias | any | the public alias ie /myfiles |
path | any | the actual path something like __dirname + '/public' |
// make content of the local public folder available at http://MYBOTURL/public/myplugin
controller.publicFolder('/public/myplugin', __dirname + '/public);
Use controller.ready()
to wrap any calls that require components loaded during the bootup process.
This will ensure that the calls will not be made until all of the components have successfully been initialized.
Parameters
Argument | Type | description |
---|---|---|
handler | A function to run when Botkit is booted and ready to run. |
For example:
controller.ready(() => {
controller.loadModules(__dirname + '/features');
});
Save the current conversation state pertaining to a given BotWorker's activities. Note: this is normally called internally and is only required when state changes happen outside of the normal processing flow.
Parameters
Argument | Type | description |
---|---|---|
bot | BotWorker | a BotWorker instance created using controller.spawn() |
Shutdown the webserver and prepare to terminate the app.
Causes Botkit to first emit a special shutdown
event, process any bound handlers, and then finally terminate the webserver.
Bind any necessary cleanup helpers to the shutdown event - for example, close the connection to mongo.
await controller.shutdown();
controller.on('shutdown', async() => {
console.log('Bot is shutting down!');
});
Create a platform-specific BotWorker instance that can be used to respond to messages or generate new outbound messages.
The spawned bot
contains all information required to process outbound messages and handle dialog state, and may also contain extensions
for handling platform-specific events or activities.
Parameters
Argument | Type | description |
---|---|---|
config (optional) | any | Preferably receives a DialogContext, though can also receive a TurnContext. If excluded, must call bot.changeContext(reference) before calling any other method. |
Trigger an event to be fired. This will cause any bound handlers to be executed. Note: This is normally used internally, but can be used to emit custom events.
Parameters
Argument | Type | description |
---|---|---|
event | string | the name of the event |
bot (optional) | BotWorker | a BotWorker instance created using controller.spawn() |
message (optional) | BotkitMessage | An incoming message or event |
// fire a custom event
controller.trigger('my_custom_event', bot, message);
// handle the custom event
controller.on('my_custom_event', async(bot, message) => {
//... do something
});
Load a plugin module and bind all included middlewares to their respective endpoints.
Parameters
Argument | Type | description |
---|---|---|
plugin_or_function | A plugin module in the form of function(botkit) {...} that returns {name, middlewares, init} or an object in the same form. |
This class extends the BotFrameworkAdapter with a few additional features to support Microsoft Teams.
- Changes userAgent to reflect Botkit instead of BotBuilder
- Adds getChannels() (MS Teams)
- Adds middleware for adjusting location of tenant id field (MS Teams)
To use this class in your application, first install the package:
npm install --save botkit
Then import this and other classes into your code:
const { BotkitBotFrameworkAdapter } = require('botkit');
This class includes the following methods:
Parameters
Argument | Type | Description |
---|---|---|
options | any |
Get the list of channels in a MS Teams team. Can only be called with a TurnContext that originated in a team conversation - 1:1 conversations happen outside a team and thus do not contain the required information to call this API.
Parameters
Argument | Type | description |
---|---|---|
context | TurnContext | A TurnContext object representing a message or event from a user in Teams |
Returns
an array of channels in the format [{name: string, id: string}]
A base class for a bot
instance, an object that contains the information and functionality for taking action in response to an incoming message.
Note that adapters are likely to extend this class with additional platform-specific methods - refer to the adapter documentation for these extensions.
To use this class in your application, first install the package:
npm install --save botkit
Then import this and other classes into your code:
const { BotWorker } = require('botkit');

Parameters
Argument | Type | Description |
---|---|---|
controller | Botkit | A pointer to the main Botkit controller |
config | any | An object typically containing { dialogContext, reference, context, activity } |
Create a new BotWorker instance. Do not call this directly - instead, use controller.spawn().
Name | Type | Description |
---|---|---|
controller | Get a reference to the main Botkit controller. |
Begin a pre-defined dialog by specifying its id. The dialog will be started in the same context (same user, same channel) in which the original incoming message was received. See "Using Dialogs" in the core documentation.
Parameters

---|---|---|
id | string | id of dialog |
options (optional) | any | object containing options to be passed into the dialog |
controller.hears('hello', 'message', async(bot, message) => {
await bot.beginDialog(GREETINGS_DIALOG);
});
Cancel any and all active dialogs for the current user/context.
Alter the context in which a bot instance will send messages. Use this method to create or adjust a bot instance so that it can send messages to a predefined user/channel combination.
Parameters
Argument | Type | description |
---|---|---|
reference | Partial<ConversationReference> | A ConversationReference, most likely captured from an incoming message and stored for use in proactive messaging scenarios. |
// get the reference field and store it.
const saved_reference = message.reference;
// later on...
let bot = await controller.spawn();
bot.changeContext(saved_reference);
bot.say('Hello!');
Take a crudely-formed Botkit message with any sort of field (may just be a string, may be a partial message object) and map it into a beautiful BotFramework Activity. Any fields not found in the Activity definition will be moved to activity.channelData.
Parameters
Argument | Type | description |
---|---|---|
message |
Returns
a properly formed Activity object
Get a value from the BotWorker's configuration.
Parameters
Argument | Type | description |
---|---|---|
key (optional) | string | The name of a value stored in the configuration |
Returns
The value stored in the configuration (or null if absent)
let original_context = bot.getConfig('context');
await original_context.sendActivity('send directly using the adapter instead of Botkit');
Set the http response body for this turn. Use this to define the response value when the platform requires a synchronous response to the incoming webhook.
Parameters
Argument | Type | description |
---|---|---|
body | any | (any) a value that will be returned as the http response body |
Example handling of a /slash command from Slack:
controller.on('slash_command', async(bot, message) => {
bot.httpBody('This is a reply to the slash command.');
})
Set the http response status code for this turn
Parameters
Argument | Type | description |
---|---|---|
status | number | a valid http status code like 200 202 301 500 etc |
controller.on('event', async(bot, message) => {
// respond with a 500 error code for some reason!
bot.httpStatus(500);
});
Replace any active dialogs with a new a pre-defined dialog by specifying its id. The dialog will be started in the same context (same user, same channel) in which the original incoming message was received. See "Using Dialogs" in the core documentation.
Parameters
Argument | Type | description |
---|---|---|
id | string | id of dialog |
options (optional) | any | object containing options to be passed into the dialog |
controller.hears('hello', 'message', async(bot, message) => {
await bot.replaceDialog(GREETINGS_DIALOG);
});
Reply to an incoming message. Message will be sent using the context of the source message, which may in some cases be different than the context used to spawn the bot.
Parameters
Argument | Type | description |
---|---|---|
src | Partial<BotkitMessage> | An incoming message, usually passed in to a handler function |
resp | A string containing the text of a reply, or more fully formed message object |
Returns
Return value will contain the results of the send action, typically `{id: <id of message>}`
Note that like bot.say(), reply()
can take a string or a message object.
controller.on('event', async(bot, message) => {
await bot.reply(message, 'I received an event and am replying to it.');
});
Send a message using whatever context the bot
was spawned in or set using changeContext() --
or more likely, one of the platform-specific helpers like
startPrivateConversation() (Slack),
startConversationWithUser() (Twilio SMS),
and startConversationWithUser() (Facebook Messenger).
Be sure to check the platform documentation for others - most adapters include at least one.
Parameters
Argument | Type | description |
---|---|---|
message | A string containing the text of a reply, or more fully formed message object |
Returns
Return value will contain the results of the send action, typically `{id: <id of message>}`
Simple use in event handler (acts the same as bot.reply)
controller.on('event', async(bot, message) => {
await bot.say('I received an event!');
});
Use with a freshly spawned bot and bot.changeContext:
let bot = controller.spawn(OPTIONS);
bot.changeContext(REFERENCE);
bot.say('ALERT! I have some news.');
Use with multi-field message object:
controller.on('event', async(bot, message) => {
bot.say({
text: 'I heard an event',
attachments: [
title: message.type,
text: `The message was of type ${ message.type }`,
// ...
]
});
});

controller.on('event', async(bot, message) => {
await bot.beginDialog('foo');
})
To use this class in your application, first install the package:
npm install --save botkit
Then import this and other classes into your code:
const { BotkitConversation } = require('botkit');
This class includes the following methods:
