Learning Puppeteer Through Short Videos

A little over a year ago, I published an article overviewing a variety of available capabilities in Puppeteer. Since the feedback was very positive, I decided to remake the content as short, focused videos.

Update (September 2026): These videos reflect Puppeteer as of 2020, and some of its APIs have changed since - check out the updated article for the current usage.

That’s only the beginning - I’m planning to make more videos, so you can save the full playlist on YouTube. Also, if you like this kind of work - subscribe to my YouTube channel today to not miss new content.

Well, here we go. 🍿
