The Lambda Function

exports.handler = function(event, context, callback) { const request = event.request; const session = event.session; const type = request.type; if (type === 'LaunchRequest') { … } else if (type === 'IntentRequest') {

  • nIntent(request, session, callback);

} else { … } };

Drilling in…

function onIntent(request, session, callback) { const intent = request.intent; const intentName = intent.name; if (intentName === 'AMAZON.HelpIntent') { … } else if (intentName === 'AMAZON.StopIntent') { … } else if (intentName === 'SetLampColour') { setLampColor(intent, session, callback); } }

function setLampColor(intent, session, callback) {

const position = intent.slots.position.value || session.attributes.position; let newSessionAttributes, responseText; if (position) { const colour = intent.slots.colour.value; newSessionAttributes = { position }; responseText = "Setting " + position + " lamp colour to " + colour; // Call Lif-X service with the position and colour … } else { responseText = "I'm not sure which lamp you want to use. Please try again.”; } callback(null, { version: '1.0', sessionAttributes: newSessionAttributes, response: {

  • utputSpeech: {

type: ‘PlainText', text: responseText, }, shouldEndSession: false } }); }
