A retort that defaults to JSON responses
A request/response wrapper for use at the very last part of your routing for JSON APIs.
Say you have a route:
"abc/`id`": function(request, response, tokens){
}To respond ok with some data in the form of JSON, you would usually have to:
"abc/`id`": function(request, response, tokens){
someFunction(tokens.id, function(error, data){
response.end(JSON.stringify(data));
});
}Which isn't so bad, but then handle the error case
"abc/`id`": function(request, response, tokens){
someFunction(function(error, data){
if(error){
//Log maybe?
console.log(error);
// set the 500 code
response.statusCode = 500;
// API error, so stringify it.
response.end(JSON.stringify(error));
return;
}
response.end(JSON.stringify(data));
});
}With JSON retorter, a set of actions has been defined that can be performed on a request, and use them to respond without having to do all that setup every time.
"abc/`id`": retorter(function(retort, tokens){
someFunction(tokens.id, function(error, data){
if(error){
return retort.error(error);
}
retort.ok(data);
});
})Which, if you use something like wraperr can be even tighter:
"abc/`id`": retorter(function(retort, tokens){
someFunction(tokens.id, wraperr(retort.ok, retort.error));
})You can also get access to the origininal request and response objects via the passed in retort object
"abc/`id`": retorter(function(retort, tokens){
retort.request
retort.response
})
