Usage

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!

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

Response Handler

The simplest way for handling response is callback function, which is specified as a last argument:

bot.postMessageToUser('user1', 'hi', function(data) {/* ... */});
bot.postMessageToUser('user1', 'hi', params, function(data) {/* ... */});

But also you can use promises.

Error:

bot.postMessageToUser('user1', 'hi').fail(function(data) {
    //data = { ok: false, error: 'user_not_found' }
})

Success:

bot.postMessageToUser('user', 'hi').then(function(data) {
    // ...
})

Error and Success:

bot.postMessageToUser('user', 'hi').always(function(data) {
    // ...
})
