Here is the Javascript version of my earlier tutorial Hello World in AWS Lambda + Amazon Alexa:

[code language=”javascript”]
‘use strict’;

function buildResponsePayload( title, output, repromptText, shouldEndSession ) {
return {
outputSpeech: {
type: ‘PlainText’,
text: output
},
card: {
type: ‘Simple’,
title: ‘alexaHelloWorld – ‘ + title,
content: ‘alexaHelloWorld – ‘ + output
},
reprompt: {
outputSpeech: {
type: ‘PlainText’,
text: repromptText,
},
},
shouldEndSession,
};
}

function buildResponse( sessionAtts, speechResponse ) {
return {
version: ‘1.0’,
sessionAtts,
response: speechResponse,
};
}

function sayHelloWorld( callback ) {
const sessionAtts = {};
const cardTitle = ‘alexaHelloWorld’;
const textOutput = ‘Hello Javascript World’;
const shouldEndSession = false;

callback( sessionAtts, buildResponsePayload( cardTitle, textOutput, textOutput, shouldEndSession ) );
}

exports.handler = ( event, context, callback ) => {
try {
sayHelloWorld( ( sessionAtts, speechResponse ) => {
callback( null, buildResponse( sessionAtts, speechResponse ) );
} );
} catch( e ) {
callback( e );
}
};
[/code]

Enjoy!
