request-data

getRequestData(maxSize[optional], raw[optional], callback)

Wraps any fn(request, response) function, parses the requests body, and calls the wrapped function with data as the last parameter.

Normal usage:

"/myRoute": getRequestData(function(request, response, data) {
  // ...
});

With a named handler:

// Handler
function handleThing(request, response, data) {
  // ...
}

handleThing will be passed the arguments of request, response, data

"/myRoute": getRequestData(handleThing);

If you want to use it with a custom router that adds params after request/response, it will still work.

// beelin syntax

"/myRoute/`things`": getRequestData(function(request, response, tokens, values, data) {
  // ...
});

By default request-data will kill a request if you try and send it more than 1e6 bytes.

This can be overriden per handler:

getRequestData(1e10, function(request, response, data){
  // ...
});

Or globally:

getRequestData.maxRequestSize = 1e10;

If dataSize is greater than maxSize or data fails to parse during JSON.parse, the parse error is passed to the handler instead of data

You can handle this case by checking if data is an error:

"/myRoute":getRequestData(function(request, response, data){
    if (data instanceof Error) {
        // Bad request
        response.statusCode = 400;
        response.end();
        return;
    }

    // Otherwise, data was valid, and has been parsed.
});
