option to disable images #20

Closed Nyoroon closed 6 years ago

Nyoroon commented 7 years ago

It's possible to have option to disable loading images when rendering? In original prerender image loading was disabled https://github.com/prerender/prerender/blob/c3a83d6ba001cac6e2dc22cacab6b7d510835e36/lib/server.js#L72 It's controlled by chrome headless CLI options or doable via api?

Didn't find any CLI options. http://peter.sh/experiments/chromium-command-line-switches/

The only API can do that is Network.setBlockedURLs, but I am not sure whether it is able to set blocked url to https?://**.jpg. Even if it can, images without extension can still be loaded.

hm, but selenium is doing that somehow https://stackoverflow.com/a/31581387

You might be able to do that with --user-data-dir option set and add a Preferences file in the right directory in user data dir then start chrome.

I think that's how chromedriver do that which applies to selenium.
