Example of Launch Request/Response using ExpressJS.
var alexa = require('alexa-nodekit');
// Route request and response ends up here.
exports.route = function (req, res) {
// Grab the necessary values from the Echo request.
alexa.launchRequest(req.body);
// Store the session and/or user data
// Respond to the Echo
alexa.response('Welcome to my app, you can say things like <action> or <action>.', {
title: 'Launch Card Title',
subtitle: 'Launch Card Subtitle',
content: 'Launch Card Content'
}, false, function (error, response) {
if(error) {
return res.status(400).jsonp({message: error});
}
return res.jsonp(response);
});
};
Example of Intent Request/Response using ExpressJS.
var alexa = require('alexa-nodekit');
// Same route used as launch, request and response ends up here.
exports.route = function (req, res) {
// Grab the necessary values from the Echo request.
alexa.intentRequest(req.body);
// Check session and/or user data
// Check the Intent Name and Intent Slots to decide on what logic to kick off.
// Respond to the Echo
alexa.response('I am an Echo response based on your intent.', {
title: 'Intent Card Title',
subtitle: 'Intent Card Subtitle',
content: 'Intent Card Content'
}, true, function (error, response) {
if(error) {
return res.status(400).jsonp({message: error});
}
return res.jsonp(response);
});
};
Example of Session Ended Request/Response using ExpressJS.
var alexa = require('alexa-nodekit');
// Same route used as launch and intent, request and response ends up here.
exports.route = function (req, res) {
// Grab the necessary values from the Echo request.
alexa.sessionEndedRequest(req.body);
// Check session and delete it.
// Respond to the Echo
alexa.response(function (error, response) {
if(error) {
return res.status(400).jsonp({message: error});
}
return res.jsonp(response);
});
};
