Chrome extension message between users

Is it possible to send messages between users directly without a server in Chrome extensions (P2P)?

Or does it require a server (NodeJS, for example)?

Maybe use Google Cloud Messaging, I do not understand the logic and work (official example extension).

Solution

  • No.

    Chrome does not give any tools to do so; any kind of interaction has to go through a 3rd-party server.

    GCM, for that matter, is just a routing service between clients and an app server.

    Extensions cannot listen for incoming connections. Chrome Apps, however, do. In that case, you can build a P2P application.
