Parsing Inbound Cisco Spark Webhook Bot Mentions using Node-Flint

A while back I wrote a post on parsing inbound Cisco Spark webhook data using the hears method with the node-flint framework by Nick Marus. After much thought and general improvement in skill as a developer I have created a much simpler way that could be potentially used with other frameworks. This allows the parsing of slash commands and fallback to a NLP processing service.

Below is a conversations module that can be used with flint. Rather than have multiple flint.hears methods for the event I now have just one using the switch method. Switch allows me to test the contents of my request string variable using regex. A much better solution than multiple flint.hears methods that has limited control over when to stop processing. Once you hit a match using switch it stops processing and performs the function in the return statement.

	/*
	Module parses all incoming requests from Spark webhooks and provides the responses for the bot from the node-flint framework.

	var _ = require('lodash');
	var botString = "YourBotName ";
	module.exports = function(flint){
	flint.hears(/(^| ).*( |.|$)/i, function(bot, trigger) {
	var text = trigger.text;
	var spaceId = trigger.roomId;
	var request = text.replace(botString,'');
	//lookup stored Spark space information using a find function
	var spData; //stored space object includes space ID and any other details.
	switch(true){
	case (/(^| )\/hello( |.|$)/).test(request):
	return hello(request, bot, trigger,spData);
