Alexa Skills Kit SDK for Node.js
The ASK SDK v2 for Node.js makes it easier for you to build highly engaging skills by allowing you to spend more time on implementing features and less on writing boilerplate code.
The ASK SDK Controls Framework (Beta) builds on the ASK SDK v2 for Node.js, providing a scalable solution for creating large, multi-turn skills in code with reusable components called controls.
The ASK SMAPI SDK for Node.js provides developers a library for easily interacting with all Skill Management APIs (SMAPI), including interaction model, intent request history, and in-skill purchasing APIs.
