Discard newly created tabs

[PIYUSH BANSAL]

Is there any way to create new tabs in discarded mode? In firefox, tabs.create api used option 'discard: true' to create new tabs in discarded mode.

But since chrome does not support anything of such type, is there any way to achieve it. I tried creating a tab and discarding right after. But clicking on that tab is not reloading the tab.

I think (automatic?) tab discarding was dropped altogether as a Chrome feature some time ago... But I might have misunderstood.

Not automatic tab discarding, but discarding them manually. I think tab discarding is still present as chrome provides tabs.discard api to discard them. But discarding them just after creation does not work.

Does discarding them after a few seconds work right now?

Code wise, this should resolve your issue:

chrome.tabs.create({

    url: "https://c306.net/",

}, tab =>

    !chrome.runtime.lastError && chrome.tabs.update(tab.id, { discarded: true })

)

However, when I try it, I get an error saying unexpected property 'discarded'. So I guess Phistuck is correct, discarding has been removed. Just the API docs haven't been updated yet.

Cheers!

You would be surprised (:)), but the documentation does not list discarded: true as supported in chrome.tabs.update.

Instead, there is the (weird) chrome.tabs.discard.

Thanks PhistucK! Learnt something new :)

Also learnt that discarding from callback of a created tab discards it right away, i.e. as a blank tab.

Based on this, my guess is to use `chrome.tabs.onUpdated` to check for tab to finish loading (status: complete), then discard it. You'd need to keep track of the tabId in your background script.
