Navigational elements are strategically placed, offering users easy access to different segments, such as stocks, commodities, and currencies.

The layout is often dynamic, with real-time updates and a user-friendly interface that caters to both novice and seasoned investors. Sections like market summaries, top news, and analysis are usually prominently displayed, ensuring users can quickly access key information upon landing on the site.

Data to Scrape:

To successfully extract data from Bloomberg, it's essential to pinpoint the specific elements within the website's structure that house the desired information. This involves understanding the HTML structure of the pages and identifying the unique identifiers associated with each data point.

1. Headline News:

• When scraping headline news from Bloomberg, developers must identify the specific HTML tags containing crucial information such as article headlines, timestamps, and related metadata. This involves meticulously examining the website's source code to pinpoint the exact elements representing breaking news.
• The scraping process focuses on retrieving real-time updates and capturing the latest and most relevant news articles. By constantly monitoring and extracting data from the identified HTML tags, users can stay abreast of breaking news developments in the financial world.

Prerequisites

Learn Basic JavaScript:

To scrape data from Bloomberg, start by understanding basic JavaScript concepts. Get familiar with DOM manipulation, which allows you to interact with different parts of a webpage. Learn how to make HTTP requests to fetch data and handle asynchronous operations for smoother coding. Knowing these basics will be essential for our project.

Get Crawlbase API Token:

To enable Bloomberg scraping, obtain a token from Crawlbase.

1. Log in to your Crawlbase account.
2. Go to the "Account Documentation" page in your Crawlbase dashboard.
3. Look for the "JavaScript token" code on that page. Copy this code; it's like a private key for communication with Bloomberg.

Set up the coding environment:

Prepare your tools for the JavaScript code. Follow these steps:

1. Create Project Folder: Open your terminal and type "mkdir bloomberg_scraper" to make a new project folder.

mkdir bloomberg_scraper

1. Navigate to Project Folder: Type "cd bloomberg_scraper" to enter the new folder, making it easier to manage project files.

cd bloomberg_scraper

1. Create JavaScript File: Type "touch scraper.js" to create a new file named scraper.js (you can choose a different name).

touch scraper.js

1. Install Crawlbase Package: Type "npm install crawlbase" to add the Crawlbase tool to your project. This tool is important because it helps you talk to the Crawlbase Crawling API, making it easier to get information from websites.

npm install crawlbase

By following these steps, you're setting up the foundation for your Bloomberg scraping project. You'll have a dedicated folder, a JavaScript file for your code, and the necessary Crawlbase tool for organized and efficient scraping.

Scrape Bloomberg Using Crawlbase

Once you have your API credentials and the Node.js library for web scraping installed, it's time to start working on the "scraper.js" file. Choose the Bloomberg page that you want to scrape. In this example, we'll focus on scraping data from the Bloomberg technology page. In the "scraper.js" file, use Node.js and the fs library to pull out information from the selected Bloomberg page. Be sure to replace the placeholder URL in the code with the actual URL of the page you want to scrape.

To use the Crawlbase Crawling API, follow these steps:

1. Ensure you have the "scraper.js" file ready, as instructed earlier.
2. Copy and paste the provided script into that file.
3. Run the script in your terminal by typing "node scraper.js".

const { CrawlingAPI } = require('crawlbase'),
  fs = require('fs'),
  crawlbaseToken = 'YOUR_CRAWLBASE_JS_TOKEN',
  api = new CrawlingAPI({ token: crawlbaseToken }),
  bloombergPageURL = 'https://www.bloomberg.com/technology';

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

function handleCrawlResponse(response) {
  if (response.statusCode === 200) {
    fs.writeFileSync('response.html', response.body);
    console.log('HTML saved to response.html');
  }
}

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

HTML Response:

Scrape Bloomberg News Article Data

This section will show you how to gather information from a Bloomberg news article page. The data we aim to collect includes the article's headline, abstract, imageURL, authors, publication date, and more. To achieve this, we'll start by obtaining the HTML code of the Bloomberg news article page. Then, we'll create a custom JavaScript scraper using two libraries: cheerio, commonly used for web scraping, and fs, which helps with file operations. The provided script goes through the HTML code of the Bloomberg news article page, picks out the necessary data, and stores it in a JSON array.

const { CrawlingAPI } = require('crawlbase'),
  fs = require('fs'),
  crawlbaseToken = 'YOUR_CRAWLBASE_JS_TOKEN',
  api = new CrawlingAPI({ token: crawlbaseToken }),
  bloombergPageURL =
    'https://www.bloomberg.com/news/articles/2024-01-18/tsmc-s-second-fab-in-arizona-delayed-as-us-grants-remain-in-flux?srnd=technology-vp';

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

function handleCrawlResponse(response) {
  if (response.statusCode === 200) {
    fs.writeFileSync('response.html', response.body);
    console.log('HTML saved to response.html');
  }
}

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

const fs = require('fs'),
  cheerio = require('cheerio');

try {
  // Read HTML content from the response.html file
  const htmlContent = fs.readFileSync('response.html', 'utf-8');

  const $ = cheerio.load(htmlContent);

  // Extracting article category, headline, and abstract
  const category = $('.Eyebrow_sectionTitle-Wew2fboZsjA- a').text().trim();
  const headline = $('.HedAndDek_headline-D19MOidHYLI-').text().replace(/\n\s+/g, ' ').trim();
  const abstractItems = [];
  $('.HedAndDek_abstract-XX636-2bHQw- li').each((index, element) => {
    abstractItems.push($(element).text().trim().replace(/\n\s+/g, ' '));
  });

  const imageUrl = $('div.ledeImage_ledeImage__nrpgq img.ui-image').attr('src');

  const author = $('.Byline_bylineAuthors-Ts-ifi4q-HY- a')
    .map((index, element) => $(element).text().trim())
    .get();

  // Extract publish date
  const publishDate = $('time').attr('datetime').split('T')[0];

  // Creating a JSON object with abstract as an array
  const jsonData = {
    category: category,
    headline: headline,
    abstract: abstractItems,
    imageUrl: imageUrl,
    author: author,
    publishDate: publishDate,
  };

  // Displaying the scraped data in JSON format
  console.log(JSON.stringify(jsonData, null, 2));
} catch (error) {
  console.error('Error reading or parsing the HTML file:', error);
}

In the first code block, the JavaScript code uses the Crawlbase Crawling API to fetch the HTML content of a Bloomberg news article page. The response is then saved to a local file named "response.html" if the HTTP status code is 200. The second block of code utilizes the "cheerio" library to parse the saved HTML file, extracting relevant information such as the article's category, headline, abstract, image URL, author information, and publish date. The extracted data is then organized into a JSON object and displayed in a structured format as shown below:

JSON Response:

{
  "category": "Technology",
  "headline": "TSMC’s Second Fab in Arizona Delayed as US Grants Remain in Flux",
  "abstract": [
    "The firm’s first fab in Arizona has been pushed back to 2025",
    "Biden White House has yet to hand out promised chip subsidies"
  ],
  "author": ["Jane Lanhee Lee", "Debby Wu"],
  "publishDate": "2024-01-18"
}
