@@lucareichelt7338 as of July 30th, it works when you use #cscourses. I had to dig a bit in the html, but i got it to work: const courses = await page.evaluate(() => Array.from(document.querySelectorAll("#cscourses .card"), (e) => ({ title: e.querySelector(".card-body h3").innerText, })) );
Thanks, Can you make more courses on puppeteer scrapping in detail + there are ni convincing courses for developing chrome extensionsin market. In you can make in-depth course for Chrome extension. Thanks.
Updates: -Use '#cscourses' instead of '#courses' and promo code no longer exists so omit that to prevent error const courses = await page.evaluate(() => Array.from(document.querySelectorAll('#cscourses .card'), (e) => ({ title: e.querySelector('.card-body h3').innerText, level: e.querySelector('.card-body .level').innerText, url: e.querySelector('.card-footer a').href, })) ) -also, to get formatted json during write, set following options. // Save data to JSON file fs.writeFile('courses.json', JSON.stringify(courses, null, 4), (err) => { if (err) throw err console.log('File saved') })
If you take a look at my search history, you'll find out that I was searching for scraping tutorials 2 days ago. I'm super happy that you released this video today. The timing is just perfect. Thank you so much!
Great tutorial for a really useful library. Thanks. Also....for anyone getting time-outs due to slow connections etc.....add this line before the 'goto' await page.setDefaultNavigationTimeout(0);
another fantastic vid, brad! you're a real one. i wanted to point out on the fs.writeFile() part, you can make it so that the JSON.stringify() method will automatically format the output in a readable way by including a third parameter; in this case, the length of array of objects. null is used to bypass the optional second 'replacer' parameter: JSON.stringify(courses, null, courses.length)
Brad, I just bought two of your udemy courses - Node masterclass and react front backend 2022. I just came here to say big thanks man so far I am super satisfied. Thanks for everything you do !
Thank you so much. I was finding it really hard to find error in my code, and as soon as I saw the screenshot method in first 5mins of your video, I tried it and got to know the error and mistake I was making. :)
Thanks, Brad! An "advanced" puppeteer tutorial would be awesome. I've wanted to combine scraping with a database that updates on cron to create a custom, one-off API with just a couple files. Just an idea. Thanks again for all your content!
Thanks for the video! This is great stuff. I used Puppeteer for a project at work, scraping charts from a web app, taking screenshots, and saving data into a .csv file. Very handy tool.
I have been trying to build a crawler for a long time but no success. With this, the possibility is endless. Thank you Brad. Your tutorial is always a top-notch. God bless
Awesome video Brad. I wanted to comment because web scraping has great use cases in the real world. I am a BA with an agency that works with a very large client in the news/journalism space (one of the largest, in fact) and I'm working with a developer that usually creates new story feed ingests for their API so they can sell/syndicate the stories out to other news outlets all over the world. This is usually done via an XML feed but this one in particular is just links to HTML pages so the developer is scraping the stories from HTML and adding them to the API (this one for soccer/football stories related to the 2022 World Cup). So creating your own API by scraping data for a particular niche or use case is quite a valid skill set to have.
After 11:00 whatever I'm trying to do I get the following error node:internal/process/promises:288 triggerUncaughtException(err, true /* fromPromise */); Can someone help
As usual another content so we can learn new things. Thanks Brad for your dedication you help us so much not only on how to code but with your open minded regarding all the aspect of programming and all the possibilities that contains. 🙏🙏
I WANT TO USE THIS OPPORTUNITY TO SAY A HUGE THANKS BRAD, YOU'RE THE BEST, YOUR TUTORIAL IS AMAZING AND EASY TO UNDERSTAND, YOU'VE HELPED A LOT OF PEOPLE WITH YOUR TUTORIAL, AND IM NUMBER ONE. PLEASE MAKE A VIDEO FOR RESET PASSWORD. I HOPE YOU READ MY COMMENT. THANKS BRAD
This is so great to see! Not too long ago I got my 1st dev role that required the use of puppeteer the majority of the time. Knowing absolutely nothing about it, I was pretty much thrown in with the wolves. But it was such an awesome learning experience!
i have tried this too many times but i still get a timeout error. can someone help me fix this? 'TimeoutError: Timed out after 30000 ms while waiting for the WS endpoint URL to appear in stdout!' is the timeout message from the command prompt
I watched and coded along 4 videos and finally, thanks to this one, I can understand this topic. Very clear and concise! I am working hard to become a front end developer and I have a test ( for a job) on web scraping next week. I feel ready now!
never forget to close the puppeteer browser. I had a web server constantly crash because we didn't close the browser when an error occurred so we kept opening browsers without closing the ones we stopped using, the server's memory eventually saturated. Lesson learned : always close the browser in "finally" in the "try/catch/finally" blocks
Incredible - thank you. Completed it. I plan to go into this further until one-click integration. One question - how would you scrape through all of the website pages in an index with Puppeteer, from page 1 - page 100 - scraping the content? And then adding this to. a CVS file later - pandas? Would appreciate your help.
This is a good intro. If you look into regular Puppeteer for scraping tutorials they often go into major projects which end up going out of date very quickly; I really enjoy your review of the basics, it makes it very accessible and easy to refer to.
great video as always. personally, I think there are loads of great scraping tools already invented (web scrapper io, octoparse etc) both free and paid that do pretty great job of scraping all kind of content and even allow one to create spiders & schedule scripts. everyone should know about those too! 😍
Hey Brad, long time viewer and have taken a few of your udemy courses. Any plans for a deployment series explaining how to properly set up and deploy full stack apps across hosts like AWS, Azure etc...?
Is there any tool or technique for automatic web scraping without directing towards any specific website. And Is this concept crawling or scraping in which automatic website elements are being returned without specifying towards any single website.
Pity that pptr can not grab informations from multiple pages and merge that to generates a single pdf. I have to generate pdf per page and use another js module to merge all the PDFs into one.
thanks, a very simple explanation !
No "promos". Yet awesome. Thanks, Brad.

P.P.S

Great tutorial. Thank you for uploading this.
Really Great Video

UPDATE! As for 2023 May, you'll have to change #courses for #cscourses, otherwise the code will return an empty array on 14:00.
Thanks for sharing this small time-saving detail! :)
