Chromedp FAQ
How does chromedp handle browser execution in headless environments?
The simplest method is to run the Go program using chromedp inside the
chromedp/headless-shell Docker image. This image includes a smaller, headless build of Chrome that chromedp can automatically detect and utilize.What is the default mode for Chrome when driven by chromedp, and how can this be changed?
By default, Chrome runs in headless mode when driven by chromedp. To override this, users can refer to
DefaultExecAllocatorOptions and an example demonstrating how to modify these default settings.How does chromedp prevent resource leaks when a Go program finishes on Linux?
On Linux, chromedp is configured to automatically force-kill any started Chrome child processes when the Go program concludes. If a long-running Chrome instance is required, it should be launched manually and connected using
RemoteAllocator.What causes a "context canceled" error in chromedp, and what does it signify?
This error occurs when the connection to the browser is lost, leading chromedp to cancel the associated context. Common scenarios include manually closing the browser, or the browser process being terminated or killed.
How can an `Action` that returns multiple values be used with `chromedp.Run`?
To use an
Action that returns multiple values with chromedp.Run, it must be wrapped with an ActionFunc. This allows the action to be executed within the chromedp.Run context while handling its return values.Source: github.com
