How to use the new v2 library ?

At first, I’m sorry if the question seems silly. I’m getting used to Actions on Google + DialogFlow in the last couple of days. I found out this node package (v2) yesterday and I’m planning to use it for my DialogFlow webhook. One problem for me is the package just recently get updated to v2 and it seems like there’s no tutorial / instructions on how to use the new v2 library. Like, from the README file I can see:

const { dialogflow } = require('actions-on-google')
const app = dialogflow()

But what to do next with the app variable ? Given I’m using express.js to build my webhook.

I think the OP would like an example with express:

I do the following inside the router class (in typescript)

import * as express from 'express'
import { dialogflow } from 'actions-on-google'

const app = dialogflow({ debug: true })

const router = express.Router()
router.use(app)

app.intent('The intent name not the action name!!!!', (conv, params) => {
    //Do something 
    conv.ask("my question")
or
    conv.close("my answer")
})
export = router

We also have a small snippet of a very basic self hosted express server in our v1 migration guide.

Here’s the snippet in case it’s helpful too:

const express = require('express');
const bodyParser = require('body-parser');
const { dialogflow } = require('actions-on-google');

const app = dialogflow();

// fulfillment code here

express().use(bodyParser.json(), app).listen(3000);
