What this diagram shows

This flowchart depicts the initial communication flow for establishing a connection between two RemoteMessenger instances: one in the Main Process (rm1) and another in the WebView (rm2). It specifically highlights rm2 sending a RemoteReady message via postMessage to rm1, indicating the readiness of the WebView messenger for further communication.

When to use it

Use this diagram to explain inter-process communication (IPC) setup, especially in applications with embedded web views (like Electron apps) or client-server architectures where a handshake is required before full message exchange. It's useful for documenting messenger initialization.

How to adapt it for your project

This diagram can be adapted to show more complex handshakes, including multiple readiness checks or negotiation steps. You could add error handling paths, message queuing mechanisms, or different message types for various stages of connection establishment. It can also be extended to include more participants or different communication channels.
