Sorry about that, editing mistake

I haven’t watched the whole series. I’m going to though

This video clears lot of my errors, currently working on rough project, where we can pass the search value from frontend and gets the results in frontend, using puppeteer at back end. But I am unable to integrate frontend(HTML page) with puppeteer code. I almost watched every KZread tutorial for this requirement but no one explains how to handle puppeteer ode from front end, would appreciate if you can create a video on this. Thanks.

Hi Michael, the new puppeteer version gives an error when using puppeteer-extra. I get this error: Error: An `executablePath` or `channel` must be specified for `puppeteer-core` Any help or update would be appreciated!

You need to download chromium locally and specific it's path using "executablePath" option

I have one comcern ,what if we are building a production we site that does web scraping using puppetier the I guess it's possible that the website we are scraping can block us so how can we bypass that issue?

You say "1" all the time in the video, then change it to "5", but you never show how or why you change it. Because of that, it's hard to follow, but I learned a general overview of puppeteer thanks!

WOW there is so much valuable info here! Just curious, are these similar techniques used to create something like a sneaker bot? Was hoping to practice the skills learned here and sneakerbot seems like a good one. I'll prob use my own e-commerce app instead since im sure that websites like nike will tools to prevent bots.

By monitor looks like we scrap pages (urls) one by one. Not in parallel.

@MichaelKitas

Жыл бұрын

No, that's not the case. Monitor shows the queue of links as we scrape a specific amount of links each time

in a 'loop' using appendFile and WriteFile is not appropriate, this leads memory issues. writeStreams should ne used.

If you use puppeteer-core, then as the error suggestes, you need to install chromium and add the path of chromium or chrome as "executablePath" in the launch options

I'm really enjoying your tutorial! Thank you! I've used puppeteer once before, when it was still newly released. I've got a site that I'd ilke to interact with but it's got a lot of embedded javascript that I can''t seem to get past. Using the pages developer tools I can see the html elements. However, downloading the page, the elements are in javascript files. Is that something you'd like to help me with? I could pay you if we can get it working. If you're interested, please let me know and I'll send you the site. ...it's nothing bad. Just an e-commerce idea that I'm trying out. cheers!

Thanks a lot for the video! But I've a question regarding the pagination. You do the while loop then the for loop goes over the items, once for loops finishes you check the next button state. I find this approach quite confusing. I think it would be a more clear if you save the "read items script" as a separate function or file and enable this code once navigation to the next page has been done. What do you think about this option?
