Electron v8 deprecation warning

See original GitHub issue

Describe the bug This is not so much a bug but for versions 8 and above of Electron. I am using v8 and I get:

DeprecationWarning: Passing functions, DOM objects and other non-cloneable JavaScript objects to IPC methods is deprecated and will throw an exception beginning with Electron 9

To Reproduce Use v8 and above of Electron.

Expected behavior I’m assuming that electron-tabs sends the webview event to main in the background. I can see the event using ‘will-attach-webview’ in main. I was trying to add src from there but still the same warning.

Please complete the following information

  • OS: Windows 10
  • electron-tabs version: 0.12.1
  • Electron version: 8

** Additionally ** Is there a reason that only ‘file’ protocol maybe used as opposed to a custom scheme protocol ?

Demo runs fine.

So your issue is definitely not related to electron-tabs. I’m closing this thread.

Just a note, not shown here - to load my local html file (not for the webview) along with its assets I have a registerFileProtocol in main. However for the tab and webview using the custom scheme does not work. Like I can’t say in the tab configuration src: app://myfile.html, even though the scheme ‘app’ serves files. I had to use src: file://myfile.html.

electron-tab is using webview src attribute under the hood without any modification. Please ask your question in Electron forums since we do not deal with registerFileProtocol here.

// I set src and preload now in main, when will-attach-webview is called

This is not the recommended way to use electron-tabs. I can’t guarantee it will work as expected if you are using it this way.

webview.send(“open:tab”, [webview, tab]);

Not 100% sure, but your IPC warning is probably caused by this instruction, since webview.send() uses IPC and webview and tab contain DOM elements.

Thanks for the help on this one. Apologies as my webview.send() hadn’t crossed my mind earlier.
