Methods
TeaBot
based on tg-yarl
(wrapper over Telegram Bot Api with additional features) package, it means TeaBot
inherits all methods from tg-yarl
.
Start methods
Depending on what type of connection with Telegram is used (webhook
or long polling
), there are 2 methods to start the bot.
TeaBot.receive(message)
To work with webhook
.
Params
- message (Object) - Message object received from Telegram using the webhook.
TeaBot.startPolling([options])
To work with long polling
.
Params
- [options] (Object) - Polling options:
- offset (Integer) - Identifier of the first update to be returned (0 by default).
- limit (Integer) - Limits the number of updates to be retrieved (100 by default).
- timeout (Integer) - Timeout in seconds for long polling (60 by default).
Dialog object
Dialog object
stores bot current dialogue with the user
, as well as commands (full list here) for communication.
It can be obtained from the first parameter in defineCommand
and defineAction
callbacks, or directly from TeaBot
object.
dialog.getAction()
Checks whether the user is in a state of action, and if so action name
will be returned, otherwise false
.
dialog.startAction(action)
Start the action. Then all processes occur in defineAction
callbacks. Action callback will be called at the next incoming message.
Params
- action (String) - Name of the action defined in
defineAction
.
dialog.performAction(action)
Perform the action. Then all processes occur in defineAction
callbacks. Action callback will be called immediately
.
Params
- action (String) - Name of the action defined in
defineAction
.
dialog.endAction([saveTemp])
Ends the action and clears dialog.tempData
.
Params
- [saveTemp] (Boolean) - If true, then
dialog.tempData
will not be cleared.
More dialog object
methods in docs.
Message object
Message object
stores processed incoming message, as well as its original copy.
It can be obtained from dialog.message
or from the second parameter in defineCommand
and defineAction
callbacks.
message.getCommand()
