Introduction

In today's digital age, the internet is a treasure trove of valuable data. As engineers, we have the opportunity to harness this data and unlock its potential. In this video, we will learn how to scrape data at an industrial scale using a scraping browser provided by Bright Data.

The Value of Data

Data is beautiful to engineers, and it holds immense value. However, finding reliable and Relevant data can be a challenge, especially when it comes to job postings. Many job positions are advertised without disclosing the salary, which can be frustrating for job seekers. In this project, we aim to scrape a job posting Website to extract relevant information and present it in a clear and concise manner. Our goal is to provide users with open job positions that match their criteria, including salary information.

Scraping Data at Industrial Scale

The internet is filled with valuable information that can be scraped, but this task can be daunting. We will use an open-source tool called Puppeteer, developed by Google, to dynamically extract information from website elements using JavaScript code. Puppeteer allows us to Interact with websites like a real user, navigating through pages and interacting with elements programmatically. However, writing complex Puppeteer code can be challenging. To simplify the process, we'll also explore a neat trick using Chat GPT to generate Puppeteer code without the hassle.

The Tools We'll Use

In addition to Puppeteer, we will utilize a service called Bright Data. Bright Data offers a scraping browser, a virtual browser that runs on their proxy network. This scraping browser comes with a variety of features to overcome common scraping challenges, such as IP blocking and captchas. By combining Puppeteer and Bright Data's scraping browser, we can scrape data at an industrial scale without encountering obstacles.

Setting Up the Project

To get started, we need to Create a Next.js app. We'll follow the necessary steps to set up our project, including installing dependencies, configuring the project structure, and setting up the necessary directories. Once the project is set up, we'll create a scraper.js file and import Puppeteer to establish the connection with the scraping browser. We'll utilize try-catch-finally blocks to handle errors and ensure the browser is closed once the scraping process is complete.

Writing the Scraper Code

In the scraper.js file, we'll write the code that performs the actual scraping. We'll start by initializing the Puppeteer connection using the browser websocket endpoint provided by Bright Data. This endpoint allows us to communicate with the scraping browser. With the scraper code in place, we can now navigate to the target website, enter search criteria, and scrape the relevant job postings. We'll use Puppeteer methods to interact with the website, click buttons, fill inputs, and extract information from the HTML code.

Running the Scraper

With our scraper code ready, we can now run the scraping process. We'll create a user interface where users can enter their search criteria, such as job title, location, and the number of jobs they want to retrieve. When the user clicks the search button, the application will call the API endpoint, triggering the scraper to perform the extraction. We'll handle the API request and response using Next.js's API routes. The scraped data will be stored in a CSV file for further analysis.

Filtering the Data

The scraped data may contain irrelevant or incomplete information. To ensure users receive only relevant and valuable job postings, we'll implement a filtering process. We'll loop through the scraped results, searching for jobs that include a salary value indicated by a pound sign. We'll Apply additional filtering Based on the maximum number of results desired by the user. This filtering process will provide users with open job positions that match their criteria and include salary information.

The Power of a Scraping Browser

In addition to Puppeteer, we'll leverage Bright Data's scraping browser to overcome common scraping limitations. Bright Data's scraping browser operates on their proxy network, allowing us to bypass IP blocking and solve captchas seamlessly. This virtual browser provides the scalability and reliability needed to scrape large amounts of data without disruptions. We'll explore the capabilities of the scraping browser and showcase how it enables us to scrape data at an industrial scale.

Conclusion

In conclusion, scraping data at an industrial scale can be a complex task, but with the right tools and techniques, it becomes achievable. By combining Puppeteer and Bright Data's scraping browser, we can effectively scrape job postings and extract valuable information. The process involves setting up the project, writing the scraper code, running the scraping process, and filtering the data. With these steps in place, we can provide users with accurate and relevant job postings that include salary information, empowering job seekers in their search for the perfect opportunity.
