JSONRPC()

NAME
jsonrpc

JSON-RPC
The jsonrpc middleware provides JSON-RPC 2.0 support. Below is an example exposing the add and sub methods:

    var math = {
        add: function(a, b, fn){
            fn(null, a + b);
        },
        sub: function(a, b, fn){
            fn(null, a - b);
        }
    };

    var date = {
        time: function(fn){
            fn(null, new Date().toUTCString());
        }
    };

    connect.createServer(
        connect.jsonrpc(math, date)
    );

When you wish to pass an exception simply invoke fn(err), or pass the error code fn(jsonrpc.INVALID_PARAMS). Otherwise fn(null, result) will respond with the given results.
