Usage


`js
var SlackBot = require('slackbots');

// create a bot
var bot = new SlackBot({
token: 'xoxb-012345678-ABC1DFG2HIJ3', // Add a bot https://my.slack.com/services/new/bot and put the token
name: 'My Bot'
});

bot.on('start', function() {
// more information about additional params https://api.slack.com/methods/chat.postMessage
var params = {
icon_emoji: ':cat:'
};

// define channel, where bot exist. You can adjust it there https://my.slack.com/services
bot.postMessageToChannel('general', 'meow!', params);

// define existing username instead of 'user_name'
bot.postMessageToUser('user_name', 'meow!', params);

// If you add a 'slackbot' property,
// you will post to another user's slackbot channel instead of a direct message
bot.postMessageToUser('user_name', 'meow!', { 'slackbot': true, icon_emoji: ':cat:' });

// define private group instead of 'private_group', where bot exist
bot.postMessageToGroup('private_group', 'meow!', params);
});
`
PROFIT!


`js
/**
* @param {object} data
*/
bot.on('message', function(data) {
// all ingoing events https://api.slack.com/rtm
console.log(data);
});
`

$3

The simplest way for handling response is callback function, which is specified as a last argument:
`js
bot.postMessageToUser('user1', 'hi', function(data) {/ ... /});
bot.postMessageToUser('user1', 'hi', params, function(data) {/ ... /});
`

But also you can use promises.

Error:
`js
bot.postMessageToUser('user1', 'hi').fail(function(data) {
//data = { ok: false, error: 'user_not_found' }
})
`
Success:
`js
bot.postMessageToUser('user', 'hi').then(function(data) {
// ...
})
`
Error and Success:
`js
bot.postMessageToUser('user', 'hi').always(function(data) {
// ...
})
