Sharing Debugger Connection with DevTools for My Extension

[Oldrich Kepka]

Hello everyone,

I am currently developing a DevTools extension for Chrome. For my extension to function correctly, it requires a debugger connection to the page. However, I've observed that this debugger connection is already established by DevTools when it's opened.

Is there a way for my extension to share the existing debugger connection with the rest of the DevTools? Alternatively, can my extension borrow the debugger connection from DevTools temporarily or somehow interact with it?

I appreciate any guidance or best practices related to this.

Best regards,

Oldrich Kepka

Not possible. Devtools session is allowed to use all of the CDP without any limits, but extensions can't do it.

Why do you want to reuse the CDP connection? According to the Chrome DevTools Protocol site, a single website can have multiple CDP connections.

Does the protocol support multiple simultaneous clients? 

Chrome 63 introduced support for multiple clients. See this article for details.

Let me check it again, I was trying it like 2 month ago. I think when I tried to connect with `debugger.attach` exception has been thrown, may be I am mistaken.

thanks for your help,

Olda

There are bugs and architectual limitations that may prevent connection e.g. when the page contains an iframe from another extension.
