MESSAGE HANDLER (Function)
A message handler (or simply handler) is an asynchronous function that takes a request message and a response handler function and calls the response handler on response message produced.
function handleNoOp(request, handleResponse) {
var response = {output: {body: ''}, status: 200};
handleResponse(response);
};
A handler can also intercept another handler, in which case it takes an extra parameter of the intercepted handler.
function interceptNoOp(request, handleResponse, intercepted) {
intercepted(request, handleResponse);
};
MESSAGE FILTER (Function)
A filter is a synchronous function that processes either the request or response message.
function filterNoOp(request) {
return request;
};
