Session Manipulation

You can access session attributes from the 4th paramter passed to your intent function, sessionAttributes. Remember to pass it back as the 3rd paramter to alexa.send(...).

Example

Assumes you have an intent called SessionIntent with a slot called city.

alexa.intent("SessionTest", function(req, res, slots, sessionAttributes) {
  var phrase = "";
  if (sessionAttributes.previous) {
    phrase =
      'You previously said "' +
      sessionAttributes.previous +
      '". I have replaced that with "' +
      slots.city.value +
      '". Please say another city name.';
  } else {
    phrase =
      'You said "' + slots.city.value + '". Please say another city name.';
  }

  sessionAttributes.previous = slots.city.value;

  var options = {
    shouldEndSession: false,
    outputSpeech: phrase
  };

  alexa.send(req, res, options, sessionAttributes);
});

Example

var express = require("express"),
  AlexaSkills = require("alexa-skills"),
  app = express(),
  port = process.env.PORT || 8080,
  alexa = new AlexaSkills({
    express: app, // required
    route: "/", // optional, defaults to "/"
    applicationId: "your_alexa_app_id" // optional, but recommended. If you do not set this leave it blank
  });

alexa.launch(function(req, res) {
  var phrase = "Welcome to my app!";
  var options = {
    shouldEndSession: false,
    outputSpeech: phrase,
    reprompt: "What was that?"
  };

  alexa.send(req, res, options);
});

alexa.intent("Hello", function(req, res, slots) {
  console.log(slots);

  var phrase = "Hello World!";
  var options = {
    shouldEndSession: true,
    outputSpeech: phrase,
    card: alexa.buildCard("Card Title", phrase)
  };

  alexa.send(req, res, options);
});

alexa.intent("Spell hello", function(req, res, slots) {
  console.log(slots);

  var phrase =
    '<speak><say-as interpret-as="spell-out">hello</say-as></speak>!';
  var options = {
    shouldEndSession: true,
    outputSSML: phrase
  };

  alexa.send(req, res, options);
});

alexa.ended(function(req, res, reason) {
  console.log(reason);
});

app.listen(port);
