NodeJS and NPM (Node Package Manager) are the backbone of modern JavaScript development. They allow you to execute JavaScript code outside the confines of a web browser and manage dependencies effortlessly. Here's a straightforward installation guide:

1. **NodeJS**: Visit the official [NodeJS website](https://nodejs.org/ 'NodeJS website') and download the latest LTS (Long-Term Support) version tailored for your operating system. Execute the installation following the platform-specific instructions provided.
2. **NPM**: NPM comes bundled with NodeJS. After NodeJS installation, you automatically have NPM at your disposal.

To confirm a successful installation, open your terminal or command prompt and run the following commands:

```bash
node --version
npm --version
```

These commands will display the installed versions of NodeJS and NPM, ensuring a smooth setup.

### Setting the Project Directory

To begin, create a directory using the `mkdir` command. It is called `ecommerce crawling` for the sake of this tutorial, but you can replace the name with one of your choosing:

```bash
mkdir expedia\ scraping
```

Next, change into the newly created directory using the `cd` command:

```bash
cd expedia\ scraping/
```

Initialize the project directory as an npm package using the `npm` command:

```bash
npm init --y
```

The command creates a `package.json` file, which holds important metadata for your project. The `--y` option instructs npm to accept all defaults.

After running the command, the following output will display on your screen:

```javascript
Wrote to /home/hassan/Desktop/ecommerce crawling/package.json:

{
  "name": "expedia-scraping",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}
```

Inside your project directory, create a new file named expedia-scraping.js. This is where you'll place the scraping code.

```bash
touch expedia-scraping.js
```

## Scraping Expedia Search Results

The vast repository of travel information and options available on Expedia is a treasure trove for travelers and analysts alike. By scraping Expedia's search results, one can obtain rich data insights that can be leveraged for various purposes. In this segment, we'll walk you through the meticulous process of scraping Expedia's search results step by step.

### Constructing the URL for Expedia Search

Every online platform operates on a structured framework, and Expedia is no exception. To initiate a search or scrape data, one needs to construct the appropriate URL that encapsulates the desired search parameters.

For instance, if you're interested in exploring hotel options in Paris for a weekend getaway, your URL might look something like:

```arduino
https://www.expedia.com/Hotel-Search?adults=2&rooms=1&destination=Paris&startDate=2023-12-26&endDate=2023-12-30
```

Breaking down the components:

- **Base URL**: https://www.expedia.com/Hotel-Search
- **Parameters**:
  - `adults=2`: Specifies the number of adults.
  - `rooms=1`: Indicates the number of rooms needed.
  - `destination=Paris`: Specifies the destination in URL-encoded format.
  - `startDate=2023-12-26`: Sets the start date for the stay.
  - `endDate=2023-12-30`: Sets the end date for the stay.

Constructing such URLs with the right parameters is the foundation of scraping accurate and relevant data from Expedia.

### Accessing HTML Content with Crawlbase Crawling API

Once you've meticulously crafted the requisite URL, the subsequent imperative is to extract the webpage's HTML content. The Crawlbase Crawling API emerges as an instrumental asset in this endeavor. Below delineates a structured approach to facilitate this operation:

1. **API Configuration**: Initialize the Crawlbase Crawling API, integrating your specific API token.
2. **Request Execution**: Employ the API to fetch the HTML content from the designated URL. To further optimize your scraping process, it's essential to understand the [parameters](https://crawlbase.com/docs/crawling-api/parameters/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Crawling API Parameters') you can employ with the Crawlbase Crawling API:

- **ajax_wait**: A boolean parameter indicating whether the API should wait for AJAX content to load. Setting it to true ensures that asynchronous content is fully rendered before capturing the HTML.
- **page_wait**: Specifies the duration, in milliseconds, for which the API should wait after the page loads before capturing the HTML. Adjusting this value can help in cases where content takes longer to become fully interactive or when dealing with sites that have intricate loading sequences.

Here's a refined example illustrating the integration of these parameters:

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

// Insert your Crawlbase JS token in place of 'YOUR_CRAWLBASE_JS_TOKEN'
const api = new CrawlingAPI({ token: 'YOUR_CRAWLBASE_JS_TOKEN' });

const options = {
  ajax_wait: true,
  page_wait: 5000,
};

const expediaURL =
  'https://www.expedia.com/Hotel-Search?adults=2&rooms=1&destination=Paris&startDate=2023-12-26&endDate=2023-12-30';

async function fetchExpediaHTML(url) {
  const response = await api.get(url, options);
  return response.body;
}

fetchExpediaHTML(expediaURL).then((response) => {
  console.log(response);
});
```

#### Execution Instructions:

- Copy and paste the above code into the expedia-scraping.js file.
- To execute the script, navigate to your project directory in the terminal and run:

```bash
node expedia-scraping.js
```

This will display the retrieved HTML in your terminal.

### Inspecting HTML to Get CSS Selectors

With the HTML content obtained from the property page, the next step is to analyze its structure and pinpoint the location of pricing data. This task is where web development tools and browser developer tools come to our rescue. Let's outline how you can inspect the HTML structure and unearth those precious CSS selectors:

![Image description](https://crawlbase.com/blog/scrape-expedia/xpedia-search-page-inspect.jpg)

1. **Open the Web Page**: Navigate to the Airbnb website and land on a property page that beckons your interest.
2. **Right-Click and Inspect**: Employ your right-clicking prowess on an element you wish to extract (e.g., a Buy Box) and select "Inspect" or "Inspect Element" from the context menu. This mystical incantation will conjure the browser's developer tools.
3. **Locate the HTML Source**: Within the confines of the developer tools, the HTML source code of the web page will lay bare its secrets. Hover your cursor over various elements in the HTML panel and witness the corresponding portions of the web page magically illuminate.
4. **Identify CSS Selectors**: To liberate data from a particular element, right-click on it within the developer tools and gracefully choose "Copy" > "Copy selector." This elegant maneuver will transport the CSS selector for that element to your clipboard, ready to be wielded in your web scraping incantations.

Once you have these selectors, you can proceed to structure your data scraper to extract the required information effectively.

### Data Extraction from Expedia Search Outcomes

Upon successfully retrieving the HTML content, the subsequent step is the meticulous extraction of essential data elements. For this task, we harness the capabilities of parsing tools, with the cheerio library in JavaScript standing out as our primary choice.

Here's a refined approach to the process:

1. **HTML Parsing**: Integrate the acquired HTML content into a parsing framework like Cheerio, enabling seamless navigation through the Document Object Model (DOM).
2. **Precise Data Extraction**: Deploy CSS selectors strategically to isolate and extract crucial data fragments from the HTML structure. This includes pivotal metrics such as hotel names, nightly rates, cumulative prices, ratings, and user review counts.
3. **Data Structuring**: As the extraction unfolds, methodically organize the harvested data into structured formats, be it JSON or CSV. This ensures clarity, accessibility, and facilitates subsequent data analysis or archival.

To align with our earlier scripting endeavors, the revised code section remains:

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

// Initialize Crawlbase API
const apiToken = 'YOUR_CRAWLBASE_JS_TOKEN'; // Insert your Crawlbase JS token here
const api = new CrawlingAPI({ token: apiToken });

// API options
const options = {
  ajax_wait: true,
  page_wait: 5000,
};

// Target Expedia URL
const expediaURL =
  'https://www.expedia.com/Hotel-Search?adults=2&rooms=1&destination=Paris&startDate=2023-12-26&endDate=2023-12-30';

// Fetch HTML content from Expedia
async function fetchExpediaHTML(url) {
  const response = await api.get(url, options);
  return response.body;
}

// Extract hotel details from HTML content
function extractHotelDetails(htmlContent) {
  const $ = cheerio.load(htmlContent);
  const hotels = [];

  $('div[data-stid="property-listing-results"] .uitk-card').each((index, element) => {
    const hotel = {
      name: $(element).find('.uitk-card-content-section h3.uitk-heading').text(),
      pricePerNight: $(element)
        .find(
          '.uitk-card-content-section div[data-test-id="price-summary"] > div > div:first-child > div span div.uitk-text'
        )
        .text(),
      totalPrice: $(element)
        .find('.uitk-card-content-section div[data-test-id="price-summary"] > div > div:nth-child(2) div.uitk-text')
        .text(),
      rating: $(element)
        .find('.uitk-card-content-section .uitk-layout-flex span.uitk-badge span.uitk-badge-base-text')
        .text(),
      reviews: $(element)
        .find(
          '.uitk-card-content-section div.uitk-layout-grid div:first-child > div.uitk-layout-flex > div:nth-child(2) > div:nth-child(2) > div:last-child > span > div.uitk-text'
        )
        .text(),
    };
    hotels.push(hotel);
  });

  return hotels;
}

// Main function to execute the scraping
async function main() {
  const htmlContent = await fetchExpediaHTML(expediaURL);
  const hotelData = extractHotelDetails(htmlContent);

  console.log(hotelData); // Display extracted hotel details
}

// Execute the main function
main().catch((error) => {
  console.error('An error occurred:', error);
});
```

Using the `CrawlingAPI` from the 'crawlbase' library, the script fetches the HTML content of a predefined Expedia URL. This content is then parsed using the `cheerio` library, a server-side implementation similar to jQuery, to extract essential hotel details like names, prices, ratings, and reviews. After processing, the script outputs the extracted data to the console. Notably, error handling is incorporated to manage any potential issues during the scraping operation.

Running above code will give output like this:

```json
[
  {
    name: 'OKKO Hotels Paris Rueil-Malmaison',
    pricePerNight: '$118',
    totalPrice: '$542 total',
    rating: '9.0',
    reviews: 'Wonderful286 reviews'
  },
  {
    name: 'Grand Hotel Leveque',
    pricePerNight: '$174',
    totalPrice: '$782 total',
    rating: '8.4',
    reviews: '1,004 reviews'
  },
  {
    name: 'Hyatt Regency Paris Etoile',
    pricePerNight: '$250',
    totalPrice: '$1,129 total',
    rating: '8.6',
    reviews: '1,002 reviews'
  },
  {
    name: 'Hotel Riviera Elysées',
    pricePerNight: '$98',
    totalPrice: '$449 total',
    rating: '7.0',
    reviews: '469 reviews'
  },
  {
    name: 'citizenM Paris Opera',
    pricePerNight: '$192',
    totalPrice: '$871 total',
    rating: '9.6',
    reviews: '76 reviews'
  },
  {
    name: 'Grand Hotel De Turin',
    pricePerNight: '$98',
    totalPrice: '$448 total',
    rating: '7.6',
    reviews: '1,002 reviews'
  },
  ... 93 more items
]
```

## Handling Pagination in Expedia

Scraping platforms like Expedia often present their search results through a series of pages, commonly known as pagination. To ensure that we capture all the desired data, we need to account for this pagination during the scraping process. Below, we'll explore how to handle pagination effectively when scraping Expedia using the Crawlbase library.

### Understanding Pagination on Expedia

Pagination on Expedia is designed to streamline user experience by displaying search results in manageable chunks. As you scroll or navigate through these results, the platform dynamically loads additional listings.

![Image description](https://crawlbase.com/blog/scrape-expedia/expedia-pagination.jpg)

To extract all listings programmatically, it becomes necessary to interact with the "Show More" button or its equivalent until no further results load.

### Handling Pagination Efficiently

To effectively handle pagination, the Crawlbase Crawling API provides a `css_click_selector` parameter. This parameter allows us to programmatically click an element on the page, triggering the loading of additional content.

When using the JavaScript token, the `css_click_selector` parameter expects a valid CSS selector, be it an ID (e.g., `#some-button`), a class (e.g., `.some-other-button`), or an attribute (e.g., `[data-tab-item="tab1"]`). It's crucial to ensure the CSS selector is correctly encoded to avoid any discrepancies.

Let's incorporate this into our existing script:

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

// Initialize Crawlbase API
const apiToken = 'YOUR_CRAWLBASE_JS_TOKEN'; // Insert your Crawlbase JS token here
const api = new CrawlingAPI({ token: apiToken });

// API options
const options = {
  ajax_wait: true,
  page_wait: 10000,
  css_click_selector: encodeURIComponent('button[data-stid="show-more-results"]'),
};

// Target Expedia URL
const expediaURL =
  'https://www.expedia.com/Hotel-Search?adults=2&rooms=1&destination=Paris&startDate=2023-12-26&endDate=2023-12-30';

// Fetch HTML content from Expedia
async function fetchExpediaHTML(url) {
  const response = await api.get(url, options);
  if (response.headers && response.headers.pc_status === 200) {
    return response.body;
  }
  return null;
}

// Extract hotel details from HTML content
function extractHotelDetails(htmlContent) {
  const $ = cheerio.load(htmlContent);
  const hotels = [];

  $('div[data-stid="property-listing-results"] .uitk-card').each((index, element) => {
    const hotel = {
      name: $(element).find('.uitk-card-content-section h3.uitk-heading').text(),
      pricePerNight: $(element)
        .find(
          '.uitk-card-content-section div[data-test-id="price-summary"] > div > div:first-child > div span div.uitk-text'
        )
        .text(),
      totalPrice: $(element)
        .find('.uitk-card-content-section div[data-test-id="price-summary"] > div > div:nth-child(2) div.uitk-text')
        .text(),
      rating: $(element)
        .find('.uitk-card-content-section .uitk-layout-flex span.uitk-badge span.uitk-badge-base-text')
        .text(),
      reviews: $(element)
        .find(
          '.uitk-card-content-section div.uitk-layout-grid div:first-child > div.uitk-layout-flex > div:nth-child(2) > div:nth-child(2) > div:last-child > span > div.uitk-text'
        )
        .text(),
    };
    hotels.push(hotel);
  });

  return hotels;
}

// Main function to execute the scraping
async function main() {
  const htmlContent = await fetchExpediaHTML(expediaURL);
  if (htmlContent) {
    const hotelData = extractHotelDetails(htmlContent);
    console.log(hotelData);
  } else {
    console.log('Something went wrong while getting HTML.');
  }
}

// Execute the main function
main().catch((error) => {
  console.error('An error occurred:', error);
});
```

In the output, you will notice that there are more results than in the previous run.

## Storing Scraped Data

After successfully extracting data from platforms like Expedia, it's imperative to have a robust system for data storage. This ensures that the data remains accessible, organized, and can be efficiently used for various purposes in the future. Let's explore two systematic approaches to store your scraped data: using CSV files and leveraging SQLite databases.

### Storing Extracted Data in CSV Format

CSV (Comma Separated Values) stands as a standard for data interchange due to its simplicity and compatibility with various software. By saving scraped data in CSV format, you ensure its widespread usability.

You can modify the existing script as follows to integrate this update.

```javascript
const { CrawlingAPI } = require('crawlbase');
const cheerio = require('cheerio');
const createCsvWriter = require('csv-writer').createObjectCsvWriter;

// Initialize Crawlbase API
const apiToken = 'YOUR_CRAWLBASE_JS_TOKEN'; // Insert your Crawlbase JS token here
const api = new CrawlingAPI({ token: apiToken });

// API options
const options = {

The `saveToCSV` function utilizes the createCsvWriter module to define a CSV writer configuration. This configuration specifies that the data should be written to a file named `hotels.csv`, and it provides the structure of the CSV with headers like "Name", "Price Per Night", "Total Price", "Rating", and "Reviews". The extracted hotel data, previously organized into an array of objects, is then written to this CSV file.

### Storing Extracted Data in SQLite Database

SQLite offers a reliable, serverless solution for data storage. By using an SQLite database, you can benefit from structured querying capabilities, ensuring data integrity and efficient retrieval.

You can modify the script as follows to integrate this update.

```javascript
const { CrawlingAPI } = require('crawlbase');
const cheerio = require('cheerio');
const sqlite3 = require('sqlite3').verbose();

// Initialize Crawlbase API
const apiToken = 'YOUR_CRAWLBASE_JS_TOKEN'; // Insert your Crawlbase JS token here
const api = new CrawlingAPI({ token: apiToken });

// API options
const options = {
  ajax_wait: true,
  page_wait: 8000,
  css_click_selector: encodeURIComponent('button[data-stid="show-more-results"]'),
};

// Target Expedia URL
const expediaURL =
  'https://www.expedia.com/Hotel-Search?adults=2&rooms=1&destination=Paris&startDate=2023-12-26&endDate=2023-12-30';

// Fetch HTML content from Expedia
async function fetchExpediaHTML(url) {
  const response = await api.get(url, options);
  if (response.headers && response.headers.pc_status === '200') {
    return response.body;
  }
  return null;
}

// Extract hotel details from HTML content
function extractHotelDetails(htmlContent) {
  const $ = cheerio.load(htmlContent);
  const hotels = [];

  $('div[data-stid="property-listing-results"] .uitk-card').each((index, element) => {
    const hotel = {
      name: $(element).find('.uitk-card-content-section h3.uitk-heading').text(),
      pricePerNight: $(element)
        .find(
          '.uitk-card-content-section div[data-test-id="price-summary"] > div > div:first-child > div span div.uitk-text'
        )
        .text(),
      totalPrice: $(element)
        .find('.uitk-card-content-section div[data-test-id="price-summary"] > div > div:nth-child(2) div.uitk-text')
        .text(),
      rating: $(element)
        .find('.uitk-card-content-section .uitk-layout-flex span.uitk-badge span.uitk-badge-base-text')
        .text(),
      reviews: $(element)
        .find(
          '.uitk-card-content-section div.uitk-layout-grid div:first-child > div.uitk-layout-flex > div:nth-child(2) > div:nth-child(2) > div:last-child > span > div.uitk-text'
        )
        .text(),
    };
    hotels.push(hotel);
  });

  return hotels;
}

// Save data into SQLite
function saveToSQLite(data) {
  const db = new sqlite3.Database('hotels.db');

  // Ensure the table exists
  db.run(`CREATE TABLE IF NOT EXISTS hotels (
        id INTEGER PRIMARY KEY,
        name TEXT,
        pricePerNight REAL,
        totalPrice REAL,
        rating REAL,
        reviews INTEGER
    )`);

  // Insert data
  data.forEach((hotel) => {
    db.run(`INSERT INTO hotels (name, pricePerNight, totalPrice, rating, reviews) VALUES (?, ?, ?, ?, ?)`, [
      hotel.name,
      hotel.pricePerNight,
      hotel.totalPrice,
      hotel.rating,
      hotel.reviews,
    ]);
  });

  db.close((err) => {
    if (err) {
      return console.error(err.message);
    }
    console.log('Data saved to SQLite database successfully');
  });
}

// Main function to execute the scraping
async function main() {
  const htmlContent = await fetchExpediaHTML(expediaURL);
  if (htmlContent) {
    const hotelData = extractHotelDetails(htmlContent);
    saveToSQLite(hotelData);
  } else {
    console.log('Something went wrong while getting HTML.');
  }
}

// Execute the main function
main().catch((error) => {
  console.error('An error occurred:', error);
});
```

The `saveToSQLite` function is designed to store hotel data into an SQLite database named hotels.db. Upon invocation, it establishes a connection to the SQLite database using the `sqlite3` module. Before inserting any data, the function ensures that a table named `hotels` exists in the database; if not, it creates this table with columns for an ID (as the primary key), hotel name, price per night, total price, rating, and number of reviews. Subsequently, the function iterates over each hotel object passed to it, executing an insertion query to add the hotel's details into the `hotels` table. Once all the data has been inserted, the function closes the database connection, ensuring that the data is safely persisted within the SQLite database.

## Frequently Asked Questions

### Is it legal to scrape data from Expedia?

Web scraping, especially from large commercial platforms like Expedia, exists in a legal gray area. While some jurisdictions and terms of service explicitly prohibit scraping, others might not have clear guidelines. It's crucial to thoroughly review Expedia's terms of service or consult with legal experts familiar with internet laws in your region. Remember, even if scraping isn't explicitly prohibited, it's essential to practice ethical scraping, ensuring you're not violating any terms or causing undue strain on Expedia's servers. Additionally, always respect `robots.txt` files, which websites often use to indicate which parts of the site can or cannot be scraped.

### Why use JavaScript libraries like cheerio for scraping?

JavaScript libraries such as cheerio are invaluable tools for web scraping tasks. Unlike traditional browsers, which execute JavaScript to render pages, cheerio operates on the server-side, providing a simulated DOM environment. This server-side approach eliminates the need for rendering the entire webpage, resulting in faster data extraction processes. Developers can employ familiar jQuery-like syntax to navigate and extract specific HTML elements, simplifying complex scraping tasks and optimizing performance.

### How can I handle rate limiting or IP bans when scraping Expedia?

Websites, including Expedia, employ various mechanisms like rate limiting or IP bans to deter and manage aggressive or unauthorized scraping activities. If you notice delays or get blocked, it's a sign that your scraping activity might be too aggressive. To navigate these challenges:

- **Implement Delays**: Introduce random or systematic delays between your scraping requests to mimic human behavior and reduce the load on the server.
- **Use Proxies**: Rotate through a pool of proxies to mask your IP address and distribute requests, making it harder for websites to track and block your scraping activity.
- **Rate Limiting Tools**: Consider integrating middleware or tools designed to manage and respect rate limits, adjusting your scraping speed dynamically based on server responses.

Additionally, for a streamlined and hassle-free experience, platforms like Crawlbase offer dedicated Crawling APIs. Leveraging such services can further automate and optimize your scraping endeavors, providing an added layer of sophistication in managing potential restrictions.

### What should I do with the scraped data from Expedia?

The ethical and legal use of scraped data is paramount. Before using the scraped data:

- **Purpose of Use**: Clearly define your intentions. If you're analyzing data for personal insights or academic research, ensure your activities align with the website's terms of service.
- **Commercial Usage**: If you plan to use the data commercially, always obtain explicit permission from Expedia or the respective website. Selling or re-purposing scraped data without consent can lead to legal repercussions and tarnish your reputation in the industry.
- **Data Privacy**: Always prioritize data privacy. Ensure that any personal or sensitive information extracted from Expedia or other sources is handled securely, respecting individual privacy rights and regulations.
