google cloud platform - How to make http call on DialogFlow v2 using Javascript ajax call

Question

I found this example on the official site of DialogFlow using Node.js and it is working fine, but I dont know how do I integrate this into my web application.

Is it possible that I can integrate this into my other javascript jquery code? and here I need to run node index.js but do I still need to do this if I integrate with my code?

const projectId = 'xxx'; //https://dialogflow.com/docs/agents#settings
const sessionId = 'xxxxx';
const query = 'Hello';
const languageCode = 'en-US';

// Instantiate a DialogFlow client.
const dialogflow = require('dialogflow');
const sessionClient = new dialogflow.SessionsClient();

// Define session path
const sessionPath = sessionClient.sessionPath(projectId, sessionId);
console.log(sessionPath);
// The text query request.
const request = {
  session: sessionPath,
  queryInput: {
    text: {
      text: query,
      languageCode: languageCode,
    },
  },
};

// Send request and log result
sessionClient
  .detectIntent(request)
  .then(responses => {
    console.log('Detected intent');
    const result = responses[0].queryResult;
    console.log(`  Query: ${result.queryText}`);
    console.log(`  Response: ${result.fulfillmentText}`);
    if (result.intent) {
      console.log(`  Intent: ${result.intent.displayName}`);
    } else {
      console.log(`  No intent matched.`);
    }
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Are there any alternative that we can use DialogFlow v2 using normal javascript jquery, ajax without me having to do node index.js everytime I want to use dialogflow.

DialogFlow v1 was quite simple to use. I had it something like this:

fetch(url, {
    body: JSON.stringify(data),
    // cache: 'no-cache',
    // credentials: 'same-origin',
    headers: {
        'content-type': 'application/json',
        "Authorization": "Bearer " + configs.accessToken,
    },
    method: 'POST',
    mode: 'cors',
    redirect: 'follow',
    referrer: 'no-referrer',
})
    .then(response => response.json()) // parses response to JSON
