### Understanding Booking.com Structure

![Image description](https://crawlbase.com/blog/scrape-booking-com/understand-booking-site-structure.jpg)

**HTML Structure of Booking.com Pages**

In this section, we'll look at how Booking.com arranges its content using HTML. It's important to understand the Document Object Model (DOM) to scrape information effectively.

- **Overview of Booking.com DOM**
  - Check out the structure from top to bottom.
  - Find the main HTML tags and features that shape the page.
- **Class and ID Naming Conventions**
  - Look into the importance of class and ID names.
  - Get information using these element identifiers.
- **Nested Elements and Relationships**
  - See how elements are placed inside one another.
  - Move through parent and child elements for thorough data extraction.

**Identifying Target Data Elements**

This part is all about figuring out the specific data you want to pull from Booking.com pages.

- **Defining Scraping Objectives**
  - Outline what information you need.
  - Make clear goals for effective scraping.
- **Inspecting Elements with Browser Developer Tools**
  - Use browser tools to look at elements closely.
  - Find and confirm the data you want accurately.
- **XPath and CSS Selectors for Targeting**
  - Introduce XPath and CSS selectors.
  - Learn to make effective selectors to get exactly what you need.

### Prerequisites for Scraping Booking.com

**JavaScript basics**

Before we start web scraping on Booking.com, it's important to know some basics about JavaScript, the programming language we'll be using. Get familiar with concepts like DOM manipulation, which helps us interact with different parts of a webpage, making HTTP requests to get data, and handling asynchronous operations for smoother coding. Knowing these basics will be really helpful as we work on our project.

**Crawlbase API token**

Now, let's talk about getting the token we need from Crawlbase to make our Booking.com scraping work.

First, login to your [Crawlbase account](https://crawlbase.com/login/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Login to Crawlbase') on their website.

Once you're logged in, find the page called "[Account Documentation](https://crawlbase.com/dashboard/account/docs/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Account documentation')" inside your Crawlbase dashboard.

![Image description](https://crawlbase.com/blog/scrape-booking-com/rawlbase-dashboard.jpg)

Look for a code called "JavaScript token" on that page. Copy this code – it's like a secret key that makes sure our code can talk to Booking.com properly.

Now that you have this token, you're all set to finish setting up the other parts of our Booking.com scraping project for it to work smoothly.

**Setting Up the Environment**

Now that we have everything ready, let's set up the tools we need for our JavaScript code. Follow these steps in order:

1. Create Project Folder:

Open your terminal and type `mkdir booking_scraper` to make a new folder for your project. You can name this folder whatever you want.

`mkdir booking_scraper`

2. Navigate to Project Folder:

Type `cd booking_scraper` to go into the new folder. This helps you manage your project files better.

`cd booking_scraper`

3. Create JavaScript File:

Type `touch scraper.js` to create a new file called scraper.js. You can name this file differently if you prefer.

`touch scraper.js`

4. Install Crawlbase Package:

Type `npm install crawlbase` to install a package called Crawlbase. This package is important for our project as it helps us interact with the Crawlbase Crawling API, making it easier to get information from websites.

`npm install crawlbase`

By doing these steps, you're setting up the basic structure for your Booking.com scraping project. You'll have a dedicated folder, a JavaScript file to write your code, and the necessary Crawlbase tool to make the scraping process smooth and organized.

## Fetching Booking.com search result page

Once you have your API credentials and installed the Node.js library for web scraping, it's time to work on your "scraper.js" file. Now, let's pick the Booking.com search results page you want to scrape. For this example, we're focusing on the [Booking.com: San Francisco, California – Search Results](https://www.booking.com/searchresults.html?ss=San+Francisco%2C+California%2C+United+States&label=gen173nr-1FCAEoggI46AdIM1gEaLUBiAEBmAExuAEZyAEM2AEB6AEB-AECiAIBqAIDuAKqp5CsBsACAdICJDc3OGZkNGYwLWZkNDMtNDJkZi1iMGY1LWM3Yjk1Y2ViNTMwONgCBeACAQ&aid=304142&lang=en-us&sb=1&src_elem=sb&src=index&dest_id=20015732&dest_type=city&ac_position=0&ac_click_type=b&ac_langcode=en&ac_suggestion_list_length=5&search_selected=true&search_pageview_id=11d949d546ca0242&ac_meta=GhAxMWQ5NDlkNTQ2Y2EwMjQyIAAoATICZW46CFNhbiBGcmFuQABKAFAA&checkin=2023-12-25&checkout=2023-12-31&group_adults=2&no_rooms=1&group_children=0 'Booking.com search results page').

![Image description](https://crawlbase.com/blog/scrape-booking-com/booking-search-result-page.jpg)

To make the Crawlbase Crawling API work, you need to set up specific parameters and endpoints. First, ensure you've made the "scraper.js" file as explained earlier. Then, copy and paste the script below into that file. Lastly, run the script in your terminal with the command "node scraper.js."

```javascript
const { CrawlingAPI } = require('crawlbase');

const crawlbaseToken = 'YOUR_CRAWLBASE_JS_TOKEN';
const api = new CrawlingAPI({ token: crawlbaseToken });

const bookingPageURL =
  'https://www.booking.com/searchresults.html?ss=San+Francisco%2C+California%2C+United+States&checkin=2023-12-25&checkout=2023-12-31&group_adults=2&no_rooms=1&group_children=0&selected_currency=USD';

api.get(bookingPageURL).then(handleCrawlResponse).catch(handleCrawlError);

function handleCrawlResponse(response) {
  if (response.statusCode === 200) {
    console.log(response.body);
  }
}

function handleCrawlError(error) {
  console.error(error);
}
```

**HTML Response:**

## Scrape Booking.com property data

In this example, we'll guide you on how to scrape property information from a Booking.com search results page. This includes details like property thumbnail image, name, location, rating, reviews, and prices. To achieve this, we'll use two JavaScript libraries: cheerio, commonly used for web scraping, and fs, which is often used for file system operations.

The provided JavaScript code utilizes the Cheerio library to scrape property details from a Booking.com search results page. It reads HTML content which you extracted from "scraper.js," in previous step, and then processes it with Cheerio, and collects information such as property name, price, rating, reviews, and image URL. The script goes through each property listing and saves the data in a JSON array.

```javascript
const fs = require('fs');
const cheerio = require('cheerio');

const htmlContent = fs.readFileSync('response-booking.html', 'utf8');
const $ = cheerio.load(htmlContent);

const allLocationData = [];

const cardSelector = '[data-testid="property-card"]';

$(cardSelector).each((index, card) => {
  const currentCard = $(card);

  const extractText = (selector) => currentCard.find(selector).text().trim();

  const locationData = {
    thumbnail: currentCard.find('[data-testid="image"]').attr('src'),
    name: extractText('[data-testid="title"]'),
    address: extractText('[data-testid="address"]'),
    roomType: extractText('ul.ba51609c35 li.a6a38de85e div.abf093bdfe'),
    rating: extractText('[data-testid="review-score"] div.a3b8729ab1.d86cee9b25'),
    review: extractText('[data-testid="review-score"] div.abf093bdfe.f45d8e4c32'),
    price: extractText('span[data-testid="price-and-discounted-price"]'),
    additionalFees: extractText('div[data-testid="taxes-and-charges"]'),
    availabilityLink: currentCard.find('[data-testid="availability-cta-btn"]').attr('href'),
  };

  allLocationData.push(locationData);
});

const jsonData = JSON.stringify(allLocationData, null, 2);

console.log(jsonData);

fs.writeFileSync('allLocationData.json', jsonData, 'utf8');
```

**JSON Response:**

- **Extracting Information from Data**

  After getting the data, the next step is to pull out the important information effectively. Learn techniques like regular expressions, DOM parsing libraries, and advanced HTML parsing methods. Adapt your approach to Booking.com's specific structure to ensure your scraper can handle different data types and structures. This guarantees accuracy and completeness for insightful analysis.

- **Cleaning and Transforming Data**

  Raw scraped data often has issues like inconsistencies, missing values, or unnecessary information. This section covers ways to clean and process data, including advanced techniques like spotting outliers and managing duplicate entries. By dealing with these problems, you ensure your data is not only clean but also ready for various analytical tasks, like statistical analysis, visualization, or machine learning.

- **Saving Data in Different Formats**

### Frequently Asked Questions

Using the Booking API has some drawbacks. First, it might not offer the same access or features as the Booking.com website. Changes to how the API works can make it tricky to integrate, and you may need to update it frequently. Dealing with authentication and API keys can be complicated.
