playwright-python VS playwright-java

Using the tools at hand is often the best approach. That said, I've spent most of the last 13 years of my career automating browsers. For years, I used Selenium with a variety of libraries. After switching to Puppeteer/Playwright, I have zero interest in going back lol. Playwright actually has first party Python support. (Puppeteer has a port called Pyppeteer, but it's no longer maintained and the author recommends using Playwright)

Last I checked, pyppeteer wasn't a thing anymore, and I haven't tried Playwright but if it has a headless mode, thats what you want so you don't have a browser open.

Playwright

there are cases where a file contains at least 2 programming languages . A case like this is when using the playwright-python library i.e. the code is mainly in python, but it can contain also JS code within a page.evaluate() function. When I try to comment out some lines within the page.evaluate() function, VS Code uses the "#" symbol, instead of "//". I can use multiple cursors to insert the "//"., but it's not so convenient, So I was wondering if there is a way to tell VS Code that this part of code is JS and it should use "//" for commenting out or if there is a plugin that can do this job (I didnt find one...)

doing some googling looks like this should basically be the python version https://github.com/microsoft/playwright-python but I haven't used it so can't vouch for it.

playwright is a modern alternative to selenium. It can perform pretty much all interations as user would do i.e clicks, scrolls and many more.

Playwright for Python has really good documentation: https://playwright.dev/python/

I used it for my https://shot-scraper.datasette.io/ tool, and wrote a bit about CLI-driven scraping using that tool here: https://simonwillison.net/2022/Mar/14/scraping-web-pages-sho...

This is implemented with Playwright, a modern alternative to Selenium maintained by Microsoft and developers who formerly worked at Google on Puppeteer. I originally implemented it in Selenium but found that typing and button presses were inconsistent and failed too often. So far Playwright seems to be more reliable. For safety, the trading functions ask for manual confirmation (press enter) to place orders.

As we saw in a previous blog post about blocking resources, headless browsers allow request and response inspection. We will use Playwright in python for the demo, but it can be done in Javascript or using Puppeteer.

Sorry. I was in shock because every time when request like this happened we asked a question about an API and if did not get anything we just told it's not possible/sustainable and client accepted it. Never I was forced to do things like that. I never would have guessed somebody does that besides of course data scrapping or SEO bots or something like that. I can't think of other solution if you really have to do that. Btw. maybe you know but if you are scrapping JS heavy apps maybe https://playwright.dev/java/ (or for other langs) would be of greater help.
