Scraping Google Maps PlaceScraping Google Maps Place Data with NodeJS

 

This is a step-by-step guide on scraping Google maps place data with NodeJS.

What would be extracted?

Preparation

Initially, we have to make a project in Node.js* and add npm packages , puppeteer-extra, puppeteer and puppeteer-extra-plugin-stealth for controlling Chromium (or Firefox, or Chrome but now we can only work with Chromium that is utilized by default) with a DevTools Protocol in both headless and non-headless modes.

To do that, in a directory with a project, open a command line to enter npm i puppeteer puppeteer-extra puppeteer-extra-plugin-stealth and npm init -y.

Note: In addition, you can utilize puppeteer with no extensions, but we strongly suggest to use that with puppeteer-extra-plugin-stealth and puppeteer-extra to prevent site detection that you are using a headless Chromium or a web driver. You could check that on a Chrome headless test site. The screenshot given here shows the difference.

Procedure

Chrome extension SelectorGadget was used for grabbing CSS selectors just by clicking on required elements in a browser. The Gif image below shows the approach of choosing various parts of results.

Complete code

Code clarification

After that, we "say" puppeteer and use StealthPlugin to write a place URL:

After that, we will write a function to get place information from a page:

And lastly, a function for controlling a browser, and find information:

Output

Google Maps Places Result API

Instead, you can utilize a Google Maps Places Result API from iWeb Data Scraping.

The difference here is that you don’t require writing any codes from the scratch and sustain it. You might also experience blocking from Google and varying selectors that will break a parser. As an alternative, you just have to repeat a structured JSON to get the required data. Check out your playground.

Initially, we have to make installation of google-search-results-nodejs. For doing this, you have to pass in the console: npm i google-search-results-nodejs

Note: For making search, we want a data parameter that must get set in next format:

Code explanation

Announce constants from necessary libraries:

After that, we write the required parameters to make a request:

After that, we wrap a search method from iWeb Data Scraping library with the promise to work further with search results:

And lastly, run a getJson function which gets place data and returns that:

Seat Reservation With Jquery And Php

Seat Reservation with jQuery

In my Online Bus Reservation System project, I got queries from many people about how to implement seat selection screen effectively. So, I decided to write on it. This post explains how to implement seat booking with jQuery. It can be used in online Bus, flight, hotel, exam support, cinema and ticket booking system.

 

HTML:

<h2> Choose seats by clicking the corresponding seat in the layout below:</h2>

    <div id="holder">

        <ul  id="place">

        </ul>   

    </div>

    <div style="float:left;">

    <ul id="seatDescription">

        <li style="background:url('images/available_seat_img.gif') no-repeat scroll 0 0 transparent;">Available Seat</li>

        <li style="background:url('images/booked_seat_img.gif') no-repeat scroll 0 0 transparent;">Booked Seat</li>

        <li style="background:url('images/selected_seat_img.gif') no-repeat scroll 0 0 transparent;">Selected Seat</li>

    </ul>

    </div>

        <div style="clear:both;width:100%">

        <input type="button" id="btnShowNew" value="Show Selected Seats" />

        <input type="button" id="btnShow" value="Show All" />          

        </div>

We will add seats in “#place” element using javascript.

Settings:

To make it generalize, settings object is used.

var settings = {

               rows: 5,

               cols: 15,

               rowCssPrefix: 'row-',

               colCssPrefix: 'col-',

               seatWidth: 35,

               seatHeight: 35,

               seatCss: 'seat',

               selectedSeatCss: 'selectedSeat',

               selectingSeatCss: 'selectingSeat'

           };

rows: total number of rows of seats.
cols: total number of seats in each row.
rowCssPrefix: will be used to customize row layout using (rowCssPrefix + row number) css class.
colCssPrefix: will be used to customize column using (colCssPrefix + column number) css class.
seatWidth: width of seat.
seatHeight: height of seat.
seatCss: css class of seat.
selectedSeatCss: css class of already booked seats.
selectingSeatCss: css class of selected seats.

Seat Layout:

We will create basic layout of seats.

var init = function (reservedSeat) {

                var str = [], seatNo, className;

                for (i = 0; i < settings.rows; i++) {

                    for (j = 0; j < settings.cols; j++) {

                        seatNo = (i + j * settings.rows + 1);

                        className = settings.seatCss + ' ' + settings.rowCssPrefix + i.toString() + ' ' + settings.colCssPrefix + j.toString();

                        if ($.isArray(reservedSeat) && $.inArray(seatNo, reservedSeat) != -1) {

                            className += ' ' + settings.selectedSeatCss;

                        }

                        str.push('<li class="' + className + '"' +

                                  'style="top:' + (i * settings.seatHeight).toString() + 'px;left:' + (j * settings.seatWidth).toString() + 'px">' +

                                  '<a title="' + seatNo + '">' + seatNo + '</a>' +

                                  '</li>');

                    }

                }

                $('#place').html(str.join(''));

            };

            //case I: Show from starting

            //init();

            //Case II: If already booked

            var bookedSeats = [5, 10, 25];

            init(bookedSeats);

 

init method is used to draw seats layout. Already booked seats array will be passed as argument of this method.

Seat Selection:

?

$('.' + settings.seatCss).click(function () {

if ($(this).hasClass(settings.selectedSeatCss)){

    alert('This seat is already reserved');

}

else{

    $(this).toggleClass(settings.selectingSeatCss);

    }

});

$('#btnShow').click(function () {

    var str = [];

    $.each($('#place li.' + settings.selectedSeatCss + ' a, #place li.'+ settings.selectingSeatCss + ' a'), function (index, value) {

        str.push($(this).attr('title'));

    });

    alert(str.join(','));

})

$('#btnShowNew').click(function () {

    var str = [], item;

    $.each($('#place li.' + settings.selectingSeatCss + ' a'), function (index, value) {

        item = $(this).attr('title');                  

        str.push(item);                  

    });

    alert(str.join(','));

})

When user clicks on available seat, it is selected and second click on same seat will unselect seat. Button “Show All” will show all booked seat numbers and “Show Selected Seats” will show selected seats only.

CSS:

?

#holder{   

height:200px;   

width:550px;

background-color:#F5F5F5;

border:1px solid #A4A4A4;

margin-left:10px;  

}

#place {

position:relative;

margin:7px;

}

#place a{

font-size:0.6em;

}

#place li

{

 list-style: none outside none;

 position: absolute;  

}   

#place li:hover

{

background-color:yellow;     

}

#place .seat{

background:url("images/available_seat_img.gif") no-repeat scroll 0 0 transparent;

height:33px;

width:33px;

display:block;  

}

#place .selectedSeat

{

background-image:url("images/booked_seat_img.gif");         

}

#place .selectingSeat

{

background-image:url("images/selected_seat_img.gif");       

}

#place .row-3, #place .row-4{

margin-top:10px;

}

#seatDescription li{

verticle-align:middle;   

list-style: none outside none;

padding-left:35px;

height:35px;

float:left;

}

In my next post, you will get how to use this in asp.net project with sql server database .

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.
