This is a sample Slack bot built with Botkit.
This bot demonstrates many of the core features of Botkit:
* Connect to Slack using the real time API
* Receive messages based on "spoken" patterns
* Reply to messages
* Use the conversation system to ask questions
* Use the built in storage system to store and retrieve information
for a user.
# RUN THE BOT:
Get a Bot token from Slack:
-> http://my.slack.com/services/new/bot
Run your bot from the command line:
token=<MY TOKEN> node bot.js
# USE THE BOT:
Find your bot inside Slack to send it a direct message.
Say: "Hello"
The bot will reply "Hello!"
Say: "who are you?"
The bot will tell you its name, where it running, and for how long.
Say: "Call me <nickname>"
Tell the bot your nickname. Now you are friends.
Say: "who am I?"
The bot will tell you your nickname, if it knows one for you.
Say: "shutdown"
The bot will ask if you are sure, and then shut itself down.
Make sure to invite your bot into other channels using /invite @<my bot>!
# EXTEND THE BOT:
Botkit is has many features for building cool and useful bots!
Read all about it here:
