This is How I Scrape 99% of Sites

[@jasonchan7147]

This is gold. You have shown your thought process and by following it I can pick up the whole web scraping concept easily. Love your video John.

[@Cheenaah-tw8xx]

You are the best teacher to learn scraping

[@i2Sekc4U]

This technique kind of only works for Client-Side Rendered sites. Not SSR sites (server side)

[@abg44]

This analysis is on the client side. Allows you to continue checking the APIs for any exploits. That allows you to find the connection medium that exchanges client data to the server

[@jan.tichavsky]

It would struggle with HTMX too, heh.

Great content as always, thanks! I'm looking forward to the fingerprint video. If I may make one request, I would love to see a video about decrypting the response when it is encrypted. I’m currently trying to deal with a website like that, and I believe the decryption process must be hidden somewhere in the JavaScript since I can see the data on the website but can’t figure out how to crack it. Thanks again for your videos, man.. I really appreciate them!

you need a secret key they keep hidden commonly in .env files not just floating around in javascript.

[@isurujn]

New to your channel. I really like your videos. Straight to the point with no fluff. I've always had a bit of a weird habit of running apps through packet sniffers just to see their API requests. I found it fascinating. Although I never really did anything with them. I've noticed that many modern websites like Instagram dynamically load data in a weird way that that cannot be seen using the inspector. Do you have a video on this?

[@drewhamilton4103]

The best part of all of this is the scammers loss aversion being used against them in the same way they use it against victims. Unlike the normal scambait shenanigans they probably feel an immense sense of loss afterwards since they already feel like the money is theirs. Overall really entertaining

[@pedroaquino3042]

Thanks a lot for this John, really helpful brother. Bests

[@dalaciu]

100% percent agree that front end scraping sucks. I remember having a hard time with python selenium because of different class names being generated with inconsistent names (maybe just to discourage scraping). For my last scraping project I used Deno Typescript. The API was only returning the HTML page for the web app and I had to install a proxy certificate on my phone and read those mobile requests that a actually returned JSON objects. You have to get creative from time to time, but there is no such thing as an unscrapable APIs😅. Thanks for sharing your workflow!

[@pr0skis]

this technique is really for CSR sites. with more and more sites switching to SSR it's not really possible to just go straight to the APIs

[@wkoell]

In most cases SSR is just for the first page, so robots get their mouth filled with right stuff. Next pages are hydrated on the client side over the API. This is the evolved pattern.

[@pedrolivaresanchez]

I’m new to data scraping, so please excuse my lack of knowledge, but I wanted to ask: since SSR delivers fully rendered content directly to the client, wouldn’t it be simpler to scrape data from SSR websites compared to CSR?

[@dexvt1862]

@@wkoell "In most cases SSR is just for the first page". Why talk when you have no idea what you're talking about? 😂

[@CodeByNumbers]

That's exactly what I was going to say.

[@hurtado-w9c]

​@@pedrolivaresanchez No, CSR pages typically include endpoints that return clean, structured data in formats like JSON (as demonstrated in the video). In contrast to SSR, where you need to parse through HTML to extract the desired data (which also includes a bunch of unwanted CSS and JavaScript).

[@Queracus]

This just saved me so much python coding and HTML scraping for financial data on interactive sites with Java. God bless you :D

I think, this was your last scraping video. Nothing else has to be told about this topic. Thank you!

[@guybrushthreepwood2910]

Very interesting. I didn't know about the TLS fingerprinting (but I did know about other kinds of fingerprinting). I agree that most sites are probably fairly easy to scrape but some seem straight impossible. There was one site that I couldn't get around with. It's anti-bot protection was super good. Scraping is such a deep and deceiving topic. It looks simple but there's so much behind it.

[@malwaredev33]

Very awesome john, insight full content, keep it up, I'm trying to continue watch your almost any video, It's very helpful

[@wontdisappoint]

I also scrape data as a living, particularly job data. This is all great information. Another really good point is sometimes you have to loop over tags In the front end to extract an ID for each item. Building robust solutions that can withstand changes is a learned skill.

[@ronburgundy1033]

How can I learn this and do it as a living? Can you make 20k a year ?

[@wontdisappoint]

@ronburgundy1033 If you're working for yourself, it could be difficult and take some time, You can build up a bunch of data that you have scraped and try to sell the data. You can sell your services to a company who wants something scraped. You can work for a company that does their own scraping. Honestly, there's a lot of ways to go about it but think of it as providing a service and providing data and you can come up with some good Solutions. In regards to learning, find some sites that you want to try and scrape and start there when you have a problem ask on stack overflow or something. There is also no code options like uipath

Well client side apps with an api is really easy like you shown, usually its server side pages where you can't grab the data from any api or xml request, so you really have to scrape whatever data between the html elements you get.

important to know this only works as long the backend from the site does not have any anti CSRF tokens on the API requests

Sadly, this has an expiration date. Sites are moving more and more towards SSR and even hydration is sometimes html.

I am a passionate webscraper as well with a few years of experience. Hardest thing to scrape in my view is online PowerBI tables (publicly avaliable data), its almost impossible to fetch the data as the backend doesn't reponse. Have you cracked it? If so, could you make a video of it some day?

[@obiwanfisher537]

I have never seen this approach, but it seems a lot easier than faffing about with website designs and puppeteer or selenium.

[@nickwoodward819]

Assume this relies on the site being a spa and having json sent? I'm looking at a site that seems to respond with html :/ Think that would also apply to SSR sites, right?

[@JohnWatsonRooney]

Yes that’s right, but if it’s ssr look in the page source there’s often a lot of json data in there to save parsing loads of html tags

I have a RAG project(ai assistant for an English aticle website(for English language learners) that I need to use all articles as a vector database for my RAG agent .

Or better to code an ai scapper from scratch instead of using an external platform to automate this for my project.

[@harryhindsight9845]

with the websites i try to scrape, i can find interesting "responses" like you've mentioned by monitoring network traffic, but when i try to directly access that API request URL in my browser, I will encounter variations of this: ""message": "403 Forbidden - Valid API key is required"".... does this just mean my target websites are intentionally preventing webscrapers from accessing them in this way? What I am doing is using playwright to tediously navigate through every page and scrape the content of each page...

[@Mars.2024]

I have one more question: Do we need to get permission from any website or contact them via email before webscapping of their content? Sometimes their guidelines and terms of use are vague. Do you take permission your videos? I ask because I want to use their data to feed into a RAG project to use as a vector data repository for semantic search for ai.

[@hurtado-w9c]

Unless OpenAI or some other LLM provider loses a lawsuit for scrapping publicly available data, I doubt it should be an issue.

[@jonrogers694]

Yes you absolutely need to get permission. This is their site, they built it, it's their data not yours. "How I STEAL data from 99% of sites" is the correct title for this video... What a scum you are, John. Build your own app instead of basing it on theft.
