multiple tabs?

[isaac....@gmail.com]

Hello,

Author of the gcd library here (https://github.com/wirepair/gcd). I'm currently testing out the headless dev branch for running large scale scanning/analysis of the web. Right now I use pools of browser tabs, but it appears the headless chrome does not support this, is this correct? I ask because attempting to do a http://127.0.0.1:9222/json/new to create a new tab returns a 500, "Could not create new page." 

Thanks!

Hi we're planning on adding some new commands to DevTools protocol for managing tabs, which should let you do what you want.  I don't have an ETA but I hope to get to this soon.

Awesome, thanks for the quick response. Will this change be global for devtools or just the headless branch?

I think we want to make this available for everyone. The headless version might accept a few more arguments about what type of tab to create, but in basic tab opening and closing should be possible in all versions.

We've just landed some new Browser domain DevTools commands to manage tabs and browser contexts:

• Browser.createBrowserContext
  
• Creates an empty browser context, this is a bit like an incognito profile except you can have as many as you like
• Browser.disposeBrowserContext
• Deletes an unused context
• Browser.createTarget
• Creates a new tab, you can specify the initial url, the window dimensions and a browser context
• Browser.closeTarget
• Closes a devtools target, if that target is a tab then the tab gets closed too

Hopefully those will prove useful!

I should probably mention you can access the Browser domain over WebSockets via  /devtools/browser in addition to /devtools/page/guid.
