Middleware for formatting responses, in order to include some default fields.
Works with Express.
This middleware sends the data as defined in the configuration template, in JSON format. For this to work, this must be the last middleware used, and no middleware before it can send the response before (unless thats desired, in case of errors or authentications problems, for example).
The template format object can access properties both from the
request object and from
If you want to send data that is not in these objects, you must add them to one of the two before calling this middleware.
var express =app =responseFormatter =template =info: '<%= res.info %>'data: '<%= res.data %>'method: '<%= req.method %>';app;
To avoid cluttering the namespace in the
response objects, it is possible to use properties nested
inside a container object. The template itself supports nested placeholders as well.
var express =app =responseFormatter =template =// Nested properties in templateinfo:message: '<%= res.fiddus.message %>'version: '<%= res.fiddus.apiVersion %>'method: '<%= req.method %>'data: '<%= res.fiddus.data %>';app;
It is possible to set the response status code through the field responseCode in the
response object. If nothing is set
to this field, response code will be 200.
- Improve template parser
- Add support to error messages formatting
