But [Dialogflow Enterprise Edition](https://cloud.google.com/dialogflow-enterprise/) only use V2 API.

This middleware convert V1/V2 json format both request and response if use V2 API on dialogflow.

const { DialogflowApp } = require('actions-on-google');
const connect = require('connect');
const dialogflowV2 = require('./dialogflow-fulfillment-v2-middleware');

const actionMap = new Map();
actionMap.set('input.welcome', welcome);

const app = connect();
app.use(dialogflowV2.v2to1());
app.use((req, res) => {
   const dialogflow = new DialogflowApp({request: req, response: res});
   dialogflow.handleRequest(actionMap);
});

app(request, dialogflowV2.v1to2(response));
