manages serializers/deserializers for API content-types/media-types
npm install reaper
Reaper picks the correct media-type for a resource based on a
request's Accept header and what the resource or server supports.
It also allows the registration of serializers / deserializers for
automatic serialization and deserialization of any formats that might
be automatically serializable/deserializable.
``javascript
var reaper = new Reaper();
reaper.register('application/json',
function(str){ return JSON.parse(str); },
function(obj){ return JSON.stringify(obj); });
reaper.isAcceptable('application/json'); // returns true
reaper.isAcceptable('/'); // returns true
reaper.isAcceptable('application/xml'); // returns false
reaper.isRegistered('application/json'); // returns true
reaper.isRegistered('application/xml'); // returns false
reaper.input("application/json", '{"hello" : "world"}'); // returns {hello : "world"}
reaper.output("application/json", {hello : "world"}); // returns '{"hello" : "world"}'
`
Additionally Reaper comes with a connect-compatible middleware that attaches a body and rawBody object to your request object that automatically uses any deserializer you may have configured for the content-type to populate the body` property. The middleware will return errors in the case of bad deserialization, or unacceptable Accept / Content-Type headers.
