startup(cli)

This is the first function called by the server immediately after it begins listening on the configured address and port (default: 127.0.0.1:1983) and before the socket accepts any client connections. It will be called only once during the server lifetime, and will provide the CLI options to the program as a Lua table cli. The server will not accept a return value from this function. However, it will abort if the function raises a Lua error.

    pub_path = "/sse",
