Hotel Price and Room Search

This application is mainly developed to help search for Hotels and book the best room with lowest price on the listing. There is a lot more depending on application,you can send to the database.

    
    ...
        var database = firebase.database();

        // [START browser]
        const browser = await puppeteer.launch({
            args: ['--no-sandbox'],
            headless: true
        });
        // [END browser]
        const page = await browser.newPage();
        await page.setViewport({
            width: 1000,
            height: 900
        });
    ...
  

You have a browser instance that runs on the server and it's termed Headless because you don't get to see the Chrome browser but it will be gathering data on the background.

You have to close the browser when you are done with the search, to reduce service costs on Google App Engine.

    ...
        
     await browser.close();
