Use Browser DevTools when the problem lives inside a webpage or browser runtime. It is the best first tool for request initiators, CORS failures, cache behavior, cookies, payloads, response bodies, and page-load waterfalls. Use an HTTP debugging proxy such as mitmproxy, Charles, Fiddler Everywhere, Proxyman, or HTTP Toolkit when you must capture configurable traffic from a mobile app, desktop app, command-line client, container, or several clients. A debugging proxy is also the strongest choice when you need breakpoints, rewrites, mocks, or replay.
Scrapy Playwright is a library that adds JavaScript rendering to Scrapy. It allows users to instruct a headless browser to scrape dynamic web pages and simulate human behavior to reduce getting spiders blocked. Scrapy is used as a web scraping library with comprehensive architecture support for common web scraping processes. Despite its power, it does lack JavaScript rendering. This is where Playwright comes in. This tutorial will explain how to set up and install Scrapy Playwright and how and why to use proxies with your setup.
Image scraping automates the entire process of collecting images online as you can collect thousands of images and save time while reducing mistakes. The process works well once you understand key elements like URL handling, file processing, and source code manipulation.
Python’s requests library should simplify making HTTP requests but occasionally, it could fail to retrieve the needed data because of an error. This article will explore the most common errors that come up with Python requests and provide some advice on how to create Python requests retry mechanisms. Two of the most common ways are through using Sessions and HTTPAdapter or by using a retry logic wrapper. We will present both options along with some handy code snippets to help you with your tasks.
Choosing between Puppeteer vs Selenium should be a straightforward concept but there are various things to keep in mind before blindly picking one over the other. They are both well-known open-source tools that are mainly used for browser automation and testing. While Puppeteer is a newer addition to the programming world, it has gained appreciation from developers due to its useful features and great performance. Selenium on the other hand has existed since 2004 and remains an industry leader in automation and offering support for multiple programming languages and platforms. This article aims to compare Puppeteer vs Selenium by looking at their installation and general differences before answering the question of Puppeteer vs Selenium.
Screen scraping extracts data from what’s visually rendered on a screen rather than from the underlying source code. Web scraping sends an HTTP request and parses the raw HTML or JSON that comes back. Screen scraping goes further: it loads the page in a browser, lets everything render (JavaScript, AJAX calls, dynamic components, all of it), and then pulls data from the result. What you see on screen is what it collects.
Businesses often use data mining as a way to predict customer behavior, optimize marketing campaigns, and identify any bottlenecks. They generate massive amounts of data through daily transactions, customer experience interactions, and operational processes. However, only about 12% of this data is properly analyzed to create meaningful insights. Data mining closes this gap through algorithms and statistical methods that find the hidden patterns in larger datasets. Through a combination of machine learning, AI, and statistical analysis, businesses can turn the raw data into business intelligence. This article will explain data mining’s development, core methodologies, and practical applications. You will learn about essential tools and find ways to measure your mining projects’ success.
Finding the best language for web scraping is a challenging task as there are many languages out there to choose from. Each language has its own level of difficulty, from Python to JavaScript to Ruby and even just Java. Picking the best language for web scraping can make or break your project’s success. As such, we will be exploring some key factors you should consider for what the best language for web scraping might be for you.
Secure Shell, or SSH, is a protocol that lets you securely connect to a remote device like a Raspberry Pi or Ubuntu server over a network. By using SSH, you can access the device’s terminal from your own computer. This is ideal for those who don’t have physical access to a device or want to manage it remotely.
Choosing between a dedicated IP vs shared IP may seem straightforward but there are a few differences in how they work, what each is used for, and what makes them unique. For individuals or businesses, choosing between a dedicated IP vs shared IP comes with knowing what they are, when and where a dedicated IP is needed vs when a shared IP is useful, and keeping important factors in mind before making the decision.
