chromedp VS linkrot

There are a billion things that you need to consider when building a decent web crawler, especially interacting with pages in the modern web. For example, a lot of content is dynamically loaded by the browser nowadays, and won't show up if you make a simple HTTP request. Open your browser devtools and look at the network tab after you make a request, and you'll see it makes loads of auxiliary requests. Some content is also only loaded after you interact with it (e.g. hover, click). For that reason I'd recommend using something like chromedp and do browser based crawling, even if it's much slower.

You could use something like the chrome dev tools (https://github.com/chromedp/chromedp) or look into JS runtimes in Go and try to handle the I/O yourself.

Thanks. I've found Chromedp [0] to be a good Selenium replacement when programming in Go. Used in conjunction with HeadlessShell [1] you can deploy a Go app into a container and do the testing all within the same container with low overhead.

Is it node specific? Could you just use https://github.com/chromedp/chromedp and run it as an actually webpage and get the value from that?

It looks like https://github.com/chromedp/chromedp is the most popular option. There's also https://github.com/playwright-community/playwright-go. Any thoughts or advice about using these tools?

The alternative is to drive, for example, Chrome with the DevTools protocol (using something like https://github.com/chromedp/chromedp or https://github.com/raff/godet (this is my version of a DevTools driver).

Go is good. I use it to scrape my site for dead links. https://github.com/spotlightpa/linkrot
