This tutorial shows you how to get started developing for Alexa Skills Kit using a Nodejs Lambda.

Prerequisites

Getting Started

Clone the Amazon Alexa Skills Kit for JavaScript repo:

$ git clone https://github.com/alexa/skill-sample-nodejs-hello-world

Go to the source code directory of the sample:

$ cd skill-sample-nodejs-hello-world/src

Run npm install to bring in dependencies:

$ npm install

Start bst proxy

For Nodejs Lambdas, bst proxy command, in addition to setting up the proxy, will run your lambda for you and even reload it on changes.

This will start the helloWorld lambda:

$ bst proxy lambda index.js

Configure your Skill

From the Alexa Skills Kit list within the Amazon Developer's Console:

Choose "Add a New Skill"

Fill out the Information tab

  • Give your skill a name and invocation phrase, 'bst nodejs sample' and 'greeter' for example

Fill out the Interaction Model

  • Copy and paste the Intent Schema from here
  • Copy and paste the Sample Utterances from here

Configure the Endpoint

When you started the proxy, bst printed out a URL that you need to configure your skill:

$ bst proxy lambda samples/helloWorld/src/index.js
BST: v0.6.5  Node: v4.3.2

Your URL for Alexa Skill configuration:
https://proxy.bespoken.tools?node-id=0c6a4f17-c86f-4024-ba26-a351ac319431

Alternatively, you can create this URL via the proxy urlgen command.

Copy and paste this URL as your endpoint:

Alexa Skill Configuration

Also make sure you select "HTTPS" and account linking to "NO".

Configure SSL

On the SSL Certificate page, select the middle radio button "My development endpoint is a subdomain of a domain that has a wildcard certificate from a certificate authority"

Test

Go to the service simulator, and type: "hello" and hit "Ask {Your Skill Name}".

You should get a valid JSON in reply:

Test your Skill

Next Steps

You can now start adding functionality to your skill. To learn more about coding Alexa Skills, see the official documentation

You can also try it out on an Alexa device like an Echo, as long as it is registered with your account. Just say "Open {Your Invocation Name}" to use it.
