Implementing speechlet

You need to implement a javascript object to represent your speechlet. This object should respond with a json object as per the SDK documentation.

The service will automatically map intents to functions on your speechlet. You will also need to add a setup and tearDown function to handle launch and exit requests respectively.

Example "Hello World" speechlet:

module.exports = function() {
    return {
        setup: function(done) {
            done({
                outputSpeech: {
                    type: 'PlainText',
                    text: "Hello World"
                },
                shouldEndSession: false
            });
        },
        helloIntent: function(name, done) { // maps hello intent with a "name" slot
            done({
                outputSpeech: {
                    type: 'PlainText',
                    text: 'Hello ' + name
                },
                shouldEndSession: false;
            });
        },
        tearDown: function(done) {
            done({
                outputSpeech: {
                    type: 'PlainText',
                    text: 'Good bye.'
                },
                shouldEndSession: true
            });
        }
    }
}
