This is a great help! I was having difficulty extracting content from a dynamic website using Scrapy and Splash a few months back. (I thought it would be interesting to scrape information from Starbucks on their different coffees...) You've inspired me to give it another go. 👊
great video! feeling more confortable with scrapy after watching some of your tutorials, had some trouble installing docker but once I solved it's easy to replicate the results
I found that video very useful. It was my introduction to splash. Please publish a video on how to wait for a particular element to load up? It would be helpful.
Great content John! Do you think you can do a vid on dealing with recaptcha? I'm having a hard time dealing with the constant cockblock from those things haha Cheers!
Sure, I use Ubuntu in WSL2, and ohmyzsh for my shell - there are some very good guides close to the top of google if you wanted to recreate this in some way
very informatics video. i am trying to scrapy a website the dynamically change content after the page is load. when i visit the link, after the page load in about less then seconds some content get updated, when i use splash with 'wait':5, or even max 30 seconds, the response is also the initial response without actually waiting for some content to updated. i will really appropriate if the author or someone in the comments can help me additional tips
Hi John, thanks for the video. It is really clear and easy to understand videos. Is it possible for you to make a video of how to use scrapy splash to login into a page. I am doing a small project of my own. I need to login into a website. The website has javascript on it, without splash render I could not get the information on the webpage.
Hello John, I am trying to avoid captcha by rotating proxies and user agent by passing them in Lua script, is it possible to rotate user agent in Lua? Because rotating user agent in scrapy code itself has no effect. Thanks
Hey! Yes you should be able to pass the proxy into splash however it’s not something I’ve done for a while so would need to look it up. I tend to use playwright now for things like this
Hi John, Hope all is well buddy. Can you do a video on web scraping using values off an Excel spreadsheet please? Openpyxl + Selenium I would love you forever if you could ☺
Hello! I've been trying to work with Scrapy and just found out with your video that this might be able to solve a problem that I have: I'm working with buttons that look like this:
@@JohnWatsonRooney Thank you very much! I'm kinda new to this and I'm migrating a code from selenium because it is way too slow, so this might be a way to speed it up. Appreciate it :D
Thanks for the video John But i faced a problem here When i tried it with other website, the data scrapable when i render it at localhost (use scrapy splash render page in browser) but not with scrapy shell Please give me your solution
@@JohnWatsonRooney Thanks for the reply. Yes, i did. But when i tried use getall() to see all the html, it didnt show me the main data I noticed, theres some script in splash render page. Is it possible that script has something to do with it?
Great tutorial. I always follow your videos. I wanna know how to prevent get blocked in scrapy-splash. If there are any links or code, Please share with me.
I am having a bit of an issue seeing the need / use case for this combination. If the to be scraped website is using dynamic content (as in provided by AJAX requests consuming an API), why not "simply" use Scrapy to consume the JSON API delivering the dynamic content directly? I.e. why have a dynamic page rendered with Splash first only to then Scrape it again in a "traditional" way by CSS selectors? Am I missing something? Thank you.
Do you recommend starting off a project immediately with splash? Or rather switch to splash whenever you discover you need to. For example I want to scrape a dutch real estate website, which is likely contested by scrapers and thus has some 'difficulty' build in. To me it seems logical to immediately use splash judging from this video.
When you assess the website you are trying to scrape you’ll see if you need to use some kind of renderer - splash works and so does playwright, one of my more recent videos covers that, you might want to consider it.
Nice video John!. I subscribe C:. Question; is there any other type of web dynamics that splash doesn't detect? It happens to me that, although using scrapy-splash I get more elements of a page X than just with scrapy, finally I do not get the elements that I am viewing in my web browser
I tried to add wait parameters, so that the page has the necessary loading time, without having good results scrapy shell 'localhost:8050/render.html?url=domain.com/page-with-javascript.html&timeout=10&wait=0.5'
I did pip install for scrapy_splash >>>Requirement already satisfied: scrapy_splash in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (0.7.2) However, when I call scrapy shell, the following pops out >>>ModuleNotFoundError: No module named 'scrapy_splash' May I ask why?
Any chance as to why I keep getting empty lists: [ ]? Happens with both scrapy and scrapy-splash. Know it's a JS website and can return the title of the webpage no problems. even after I get ValueError: invalid hostname: after fetching.
@@JohnWatsonRooney Thanks for the reply, John. Managed to get the data I want with bs4 and selenium using another one of your vids! ;) Found it was a lot easier that way.
as i am tryin to run scrapy shell after updating the settings.py, 0I am constantly coming across this error "ModuleNotFoundError: No module named 'scrapy_splash'" although scrapy_splash is already installed in my venv. I need help asap
@@JohnWatsonRooney Thanks, man! I'm trying now with selenium and I could extract them but I don´t know why I can not iterate to all posts. It only extracts the first one.
I'm not sure my messages are posted as I can"t see them, but just to say that I found why my script didnt work I forgot to add the last comma in the yield dict after the second line 'price', it didnt give any error message it just didnt scrape anything only because of that
Hi @@JohnWatsonRooney! Thank you yes I posted a pastbin link, the code is working now and I think that when we use xpath selectors instead of css, it doesnt behave the same, I think I did the exact same code with xpath as a test, and the loop only returns the first result several times and I can't figure out why, did you notice this problem before?
What's the keyboard shortcut for moving the terminal line to the top of the terminal? Essentially clearing the screen, but while you're in scrapy shell?
Thanks for this, you have been the only person I watch when it comes to scraping. Love these videos

Hello John,
Can we use Splash with the Scrapy Crawl template?
Hi John, thanks for the great teaching. How can I follow the product's link through splash and scrap the information i.e description. Thank you.
great tutorial thank you!
I have a csv list of around 50 urls to scrape, how can i add the csv in the start_urls with scrapy and splash? thanks!
Hi! You can open the csv and import the urls as normal at the top of the spider, the add them to the start urls list for the spider to use
Is it posible to use splash with CrawlSpider? Or use linkExtractor with splash? Thanks you very much for your videos
Yes it is, splash works on the request part of the script it doesn’t matter what you use before that
Also, I'm a Beginner. Which Tool should I use : bs4, scrapy, splash or any others ?
Learn how to use requests and bs4 first on non JavaScript websites - then move onto scrapy and splash
@@JohnWatsonRooney Thanks for the Reply. Your Videos helps a lot 🤗
So what brand of beer would you recommend?
Nice share
Awesome video,
Can you please tell me how can I setup rotating proxies in scrapy-splash?
Good video! Do you mind if I ask what command line program you are using in the video?
Sure, I use Ubuntu in WSL2, and ohmyzsh for my shell - there are some very good guides close to the top of google if you wanted to recreate this in some way
@@JohnWatsonRooney I really appreciate it.
docker is mandatory for splash?
Had to declare ROBOTSTXT_OBEY = False.

Hey, you can do that with lua scripting with splash - I haven’t done it myself before but I know it’s possible
@@JohnWatsonRooney thanks I will read more docs and try. I already tried lua scripting a little bit, but it results some errors I need to figure out.

Hey John,
I get empty brackets when I run the response.css() command, any recommendations?
hi, John thanks for these amazing videos please how we can deploy this script on Heroku any idea sir?
How did you start the splash docker for your scrapy shell?
When I try it says can't get permission...
Great videos, really helpful!
Any chance you can show us a bit of scripting with Lua and scrapy-splash?
Thumbs up from Italy
Sure thing! I am going to extent my Scrapy series and will include some LUA scripts for Splash to allow us to perform a few tasks with it!
AMAZINGGGGG

Try to render the page with splash via the splash web page - use the default script there and you can see what it’s actually returning for you

Ctrl + L or type clear I think they works too
