When scraping websites for all important data, developers are looking for, above all, privacy and security. Using proxies is the best and most effective way to do so without the risk of exposing your IP address, making it less likely that those sites will ban your address in future visits.
Axios is a popular JavaScript Node.js library frequently used for website scraping. It’s a popular tool used widely due to its fast and accurate downloading of website content.
Puppeteer is a powerful tool for automating web testing and scraping. However, it is still subject to problems and bugs like any other software.
It's crucial to have a well-thought-out plan for solving issues in place for times like these.
In this post, we'll explore some of the best practices for Puppeteer debugging and troubleshooting with Puppeteer.
Web scraping is the process of extracting necessary data from external websites. It’s a valuable skill that helps you gather large amounts of data from the internet for various purposes. However, it can be daunting if you don’t need what tools to use.
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.
While communicating with our web scraping API users, we've found that many of them use a whole web page text extraction for further data manipulation.
It's interesting, as such an approach simplifies the needed data extraction by just picking the particular text row from the text or using RegExp.
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 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.
In this article, we'll take a look at how to submit forms using Playwright. This knowledge might be beneficial while scraping the web, as it allows to get the information from the target web page, which requires providing parameters before.
In this article, we will share several ideas on how to download files with Playwright. Automating file downloads can sometimes be confusing. You need to handle a download location, download multiple files simultaneously, support streaming, and even more. Unfortunately, not all the cases are well documented. Let's go through several examples and take a deep dive into Playwright's APIs used for file download.
Dynamic languages are helpful tools for web scraping. Scripting allows users to rapidly tie together complex systems or libraries and express ideas without dealing with memory management or build systems.
JavaScript is the most popularly used dynamic language, operating on every device with a web browser, and Node.js as a JS runtime proved to be a very successful software platform. Due to design mistakes, it became hard to evolve with an existing user base, so Deno was born to resolve all the problems. Let's find out how to scrape the web and dynamic websites with Deno.
