使用Google Home和NodeJS设置一个非常简单的“开启设备”功能？

Question

So far I've found plenty of guides online that shows how to set up a NodeJS backend, that Dialogflow can talk to. However, Dialogflow was previously API.AI and all the old guides are basically wrong now.

When I try to do this:

require('actions-on-google').ApiAiAssistant

It will tell me:

Importing the class name ApiAiAssistant is DEPRECATED , use DialogflowApp

But even changing ApiAiAssistant to DialogflowApp won't work. Here's an example of some Action: https://github.com/greenido/bitcoin-info-action/

As you can see, it has not been updated in a long time, nor does the code actually work (even if I import the intents and so on into Dialogflow).

What I basically want: Give Google Home parameters (like turn on TV which would take TV as a parameter) and handle that in my NodeJS backend. How would I do something like that? It can be with or without Dialogflow.

Also, is it even possible to say Hey Google, turn on TV ? So far all examples I've seen it like Hey Google, launch MY_ACTION or Hey Google, ask MY_ACTION to INTENT which is slow and annoying.

Got some updated code. Works fine with the DialogflowApp:

const fs = require("fs");
const express = require("express");
const https = require("https");
const bodyParser = require("body-parser");
const Assistant = require('actions-on-google').DialogflowApp;

const app = express();
app.use(bodyParser.json());

const options = {
    cert: fs.readFileSync("./cert.pem"),
    key: fs.readFileSync("./key.pem"),
    ca: fs.readFileSync("./chain.pem")
};

app.post("/google", (req, res) => {
    const assistant = new Assistant({ request: req, response: res });
    let device = assistant.getArgument("device");
    assistant.tell("Turning on " + device);
});

app.listen(5004);
https.createServer(options, app).listen(5005);
