Python libraries such as Beautiful Soup or Scrapy suit developers, headless browsers like Playwright handle JavaScript-heavy sites, and a web scraping API takes care of proxies and blocks for you. Our 259 guides on this topic cover the options. Start with What Is Web Scraping? From an HTML Page to JSON.

Technology brings new opportunities. And every few years, there comes a new thing, which is hyped up so much that it is believed that it will change everything. After cryptocurrency, we got a new thing. Something that many thought to be an unstable bubble – about to pop any second; while others think of it as the future. Say hello to NFT.
HR or Human Resources is a department as important as any other in a business or a corporation. It helps manage the workforce so that workers are happy and a healthy environment is created, which helps achieve the organization's targets.
In a world where we have employed computers, AI, and the internet to better everything, why should HR lag behind? After all, if the employees are loyal and happy where they work, they are more likely to give their all while doing their jobs, all of which ultimately leads to growth. In order to do that, many big companies have made use of a newer approach, using public web data in order to improve human resource processes.
A flood of information and data runs on the web. In this global age, people use the internet to achieve almost everything. Everything they click on, things they search for, and the websites they spend the most time on translates to user behavior and tells us about what they like to see. Such information is invaluable and is waiting right there in front of us.
Collection of such data, ensuring proper data processing with the help of data collection can help your eCommerce business grow in ways unimaginable.
Web scraping specialists are dealing with using proxy servers to overcome various anti-bot defenses every day. One of those protections is IP rate limiting, a primary anti-scraping mechanism.
Let's learn more about this protection method and the most effective ways of bypassing it.
Using a quality proxy server is the key to a successful web scraper. A variety of IPs along with their quality make it possible to collect data from various web sites without worrying about being blocked.
Still, many websites provide free proxy lists, so can the process of getting IP addresses from them be automated? Are free proxies good enough for web scraping? Let's check it out.
Making POST, PUT, and DELETE requests is a crucial web scraping and web testing technique. Still, this functionality is not included in Puppeteer's API as a separate function.
Let's check out the workaround for this situation and create a helper function to fix this out.
The earlier article described DOM Range selection as Ctrl+A/copy-paste and claimed it could recover text from sites using display optimizations. The example performed neither keyboard input nor clipboard copying, and the general recovery claim was unsupported. This refresh compares actual text returned by five methods on a controlled fixture. Code and captured outputs.
For the readable text of an already rendered page, start with page.$eval('body', body => body.innerText). Use textContent when you explicitly want descendant text that can include hidden content and script/style source. If the HTML already contains the data, a converter such as html-to-text can work without a browser.
Those methods produce different outputs. Below, the browser sees three dynamically populated products, while the raw HTTP response contains empty product placeholders. The examples show how that difference affects text extraction, and when to keep structured records instead of flattening the page.
Working with images in NodeJS extends your web scraping capabilities, from downloading the image with an URL to retrieving photo attributes like EXIF. How to achieve the image download and obtain the data?
This article is a part of the series on image downloading with different programming languages. Check out the other articles in the series:
Replaced incomplete snippets and broad speed claims with a runnable CSS/XPath extraction example, captured JSON and explicit failure controls. The evidence packet records the tested versions and limits.
To parse HTML in C#, use an HTML parser to build a document, select the elements you need, then convert their text and attributes into validated records. AngleSharp provides CSS selectors and a DOM-style API; Html Agility Pack provides XPath selection. The right starting point is usually the selector language your application already uses.
This tutorial extracts the same product records with both libraries. It covers relative URLs, encoded text, selectors that match nothing and records with missing fields. The example parses HTML already supplied to the application; fetching a page and executing its JavaScript are separate steps.
This article will expose how to block specific resources (HTTP requests, CSS, video, images) from loading in Playwright. Playwright is Puppeteer's successor with the ability to control Chromium, Firefox, and Webkit. So I'd call it the second one of the most widely used web scraping and automation tools with headless browser support.
