Allow session to end after a response is given

[steve228uk]

Currently when a response is given Alexa will continue to listen as the session is not ended. It might be a good idea to expose this as an option so the middleware does not need to be edited manually.

The same could be said for the stop intent response:

I agree, this would be a good parameter to expose

This is a much needed feature. Current workaround is to set a sessionAttribute in Content Designer item {{setSessionAttr 'shouldEndSession' true}}. And then amend fulfillment/lib/middleware/alexa.js assemble() to

exports.assemble=function(request,response){

    let sessionAttributes = _.get(response,'session',{});

    return {
        version:'1.0',
        response:{
            outputSpeech:_.pickBy({
                type:response.type,
                text:response.type==='PlainText' ? response.message : null,
                ssml:response.type==='SSML' ? response.message : null,
            }),
            card:_.get(response,"card.imageUrl") ? {
                type:"Standard",
                title:response.card.title || request.question,
                text:_.has(response.card,'subTitle')? response.card.subTitle +"\n\n" + response.plainMessage:response.plainMessage,
                image:{
                    smallImageUrl:response.card.imageUrl,
                    largeImageUrl:response.card.imageUrl
                }
            } : {
                type:"Simple",
                title:_.get(response,"card.title") || request.question || "Image",
                content:_.has(response.card,'subTitle')? response.card.subTitle +"\n\n" + response.plainMessage:response.plainMessage
            },
            shouldEndSession:_.get(sessionAttributes,'shouldEndSession',false)
        },
        sessionAttributes:sessionAttributes
    }
}
