Listen for Slack Slash Commands

var express = require('express'),
  bodyParser = require('body-parser'),
  slackCommander = require('slack-commander');

module.exports = function () {
  var app = express();

  app.use('/slack', slackCommander.router({
    token: 'SLACK_SLASH_COMMAND_TOKEN',
    commands: 'HASH_OF_SUPPORTED_COMMANDS'
  }));

  return app;
};

Example Command Hash

Commands are expected to return promises.

var Promise = require('bluebird'),
  commands = {
    reverse: function (command, input) {
      return Promise.resolve()
        .then(function () {
          var reversed = input.split('').reverse().join('');
          // ... use messenger to log this back to a chat
          return;
        });
    },
    echo: function (command, args) {
      return Promise.resolve()
        .then(function () {
          // ... use messenger to log this back to a chat
          return;
        });
    }
  }
