In my opinion as i developed multiple web scraping application, half of the time is not spent coding but instead trying to reverse engineer the web application. Simple ones are just matter of looking at requests from dev tools and manually make api calls, while most complicated ones involve backtracing how content is loaded on the page to find the js code responsable to do that. Basically its 70% reverse engineering and 30% coding, if you do things the smart way.
@@Anthony-qg5hj I had a selenium project in which I tried the approach you’re talking about. Not only needed to attach the login cookies (which expire) to the request anyway but also I needed to manually construct the request skeleton. So in the end I had a similar effort as I would have if I just force selenium to click buttons
interesting timing to see this video, literally the day after I completed my first full-stack application which literally revolves around web-scraping :D
i started learning about web scraping YESTERDAY, and stumbled upon your video today. GODDAMN the way you explain stuff and speak really stuck with me! thank you for providing such value and motivating me to improve my communication skills as well :D
I am working on building a project that heavily requires scraping so I been doing a lot of research. And its really hard to find anything good that is not sponsored by brightdata. I get it, their marketing team has done a great job with tapping a perfect niche of creators who provide valuable information but this also creates a problem to ending up finding that almost each good resource is related to using brightdata and its not something I want to pay for when starting a hobby project. Anyway, this is a great video either way. I learned a lot of things I hadn't considered in my planning. Like the ETL(thats a new rabbit hole I need to dive into) or adaptive content extraction to account of layout changes. I was just assuming I will set up reporting to notify me when I start getting no content and then I will fix it. So thank you for that. Do you setup redis or something to make sure some requests are accessed from the cache of recently requested data than scraping again or accessing the db? is that necessary? And at what point should a webhook be setup and for what purpose exactly? Thank you
I remember starting to watch your videos when I was entering computer science Ba, and as a 28 year old 1 semester left to graduate, you’re still uploading good content that’s unique. Never get tired of your vids , keep it up brother . I’m also concerned with the job market , can you make a vid about new grad Cs students ? For example seems almost every job wants front end or something and my school never taught any of it
You want to get a job from what your school taught you? You are in for a ride brother. Tech is about your own research and self learning, every fucking day.I pity people that majored in CS because they heard about a programmer earning 6figs
Unless u went to ivy league and wanna be a quant then u gotta do front end js react sql are key for majority. School is duhm unless ivybleague except for piece of paper
I saw this video recommended to me about two days after I had to scrape a ton of images and convert them to a PDF. The images are loaded dynamically and I will confess with shame that my script would scroll slowly down the entire page until it couldn't get any further. Then it would queue up all the appropriate image files and compile them into a local directory before turning them into a single PDF file.
Thank you for the amazing video! Much appreciated as a young web developer. By the way, none of the buttons lit up or did any animations... I am a subscriber, so I don't know if that's why. Peace!!!
AFAIK the button highlighting is a feature based on video subtitles, including those generated automatically, but still somewhat random. I didn't catch those because I was already subscribed and like the video a moment before you said it.
I don't think its a video subtitles feature. It just happens randomly in my experience. The thumb up button shakes and subscribe highlights. Didn't happen for me on this video though :(
Amazing content, Brother, please make a video explaining how to scrape dybamically loading powerBI tables on a website. There is simply no change in the html/css structure when you engage😅

Hi Forrest. I was wondering how you still feel about AI and the future of software engineering. With chat GPT out for over a year now, have your views changed much? Maybe a good topic for another vid.
u said u prepared the video without the need of brightdata but for every issue except data storage u propose using brightdata for the most important&challenging parts....................? :/
if you are using selenium,puppeteer, or any other browser automation, you will never be a good web scraper, they are just too damn slow, if you are relying on them to get you passed the WAF javascript function and generate your cookies for you to then go scrape others will beat you to the punch with pure code
@@consolemodding1015 if you have to login repeatedly and solve captcha's, that delay is almost negated , pure code bots just generate new valid cookies, once you hit your 403 forbidden or 401 captcha new tokens are loaded and carry on, not to mention threads instead of instances, , reversing the WAF JS function is the key. a good pure code bot vs a good browser bot is likely to be around 100x more efficient
How can you scrape dynamic content without these tools? Anything else besides trying to find the API endpoint? I am a beginner who knows how to scrape simple pages. I want to learn how to scrape dynamic content. Would love to know your thoughts.

Yep!
What's the benefit of manually doing API calls instead of just letting selenium click the buttons which will do the exact same thing?
@@mateusb09selenium has overhead
@@mateusb09 because it's faster, less code, lower cost, easier to maintain

Yeah. Scraping a dynamic website really makes me want to scream like Linus Torvalds to NVIDIA. And I also hate CloudFlare 😂
You can start a new browser or new context for every "goto()" with a different user-agent, that's how i do with CloudFare
