## 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){
try {
this(null, a + b);
} catch (err) {
this(err);
}
},
sub: function(a, b){
try {
this(null, a - b);
} catch (err) {
this(err);
}
}
};
var date = {
time: function(){
this(null, new Date().toUTCString());
}
};
module.exports = Connect.createServer(
Connect.jsonrpc(math, date)
);
The value of _this_ becomes the async callback function. When you wish to pass an exception simply invoke `this(err)`, or pass the error code `this(jsonrpc.INVALID_PARAMS)`. Other `this(null, result)` will respond with the given results.
