Usage

Hello World

var Tinybot = require('tinybot');
var bot = new Tinybot('mySecretSlackToken');

bot.say("Hello world");               // posts to #general by default
bot.say("Hello world", "#random");    // post to a channel by name
bot.say("Hello world", "C123456789"); // post to a channel by ID

Basic listener: fires for every message over slack websocket

var Tinybot = require('tinybot');
var bot     = new Tinybot('mySecretSlackToken');

bot.on('message', function(message) {
  // message contains unedited message from slack websocket
  bot.say(`Message received: ${JSON.stringify(message)}`);
})

Filtered listeners

var Tinybot = require('tinybot');
var bot     = new Tinybot('mySecretSlackToken', '#random');

// listen for only messages in a channel
bot.hears({channel: '#general'}, function() {
  bot.say("I heard that!", '#general')
})

// rain on everyone's parade with regex matches
bot.hears({channel: '#general', text: /I love (.*)/}, function foo(message, matches) {
  bot.say(`${matches[1]} sucks`);
})

// trolls anyone who posts in #random from an iPhone with nested matchers
bot.hears({channel: '#random', "file.name": /Slack for iOS/}, function fooBar(message) {
  bot.say("ooooh, fancy", '#random');
})

// snooze one meeting with hearsOnce
bot.hearsOnce({channel: '#sales', text: /meeting/}, function() {
  bot.say("let's circle back and put a pin in this. I'm gonna take a quick 5", '#sales');
})

bot.drop(/foo.*/); // deregister functions named foo and fooBar
bot.drop(/.*/);    // deregister all listeners
