Alexa SDK team is proud to present the new Alexa Node.js SDK -- the open-source Alexa Skill Development Kit built by developers for developers. Creating an Alexa skill using the Alexa Skill Kit, Node.js and AWS Lambda has become one of the most popular ways we see skills created today. The event-driven, non-blocking I/O model of Node.js is well-suited for an Alexa skill and Node.js is one of the largest ecosystems of open source libraries in the world. Plus, AWS Lambda is free for the first one million calls per month, which is sufficient for most Alexa skill developers. Also, when using AWS Lambda you don't need to manage any SSL certificates since the Alexa Skills Kit is a trusted trigger.
