Custom mapping functions

[jongunter]

Hi there...great library! I usually use automapper-ts, but this is more lightweight and easier to configure.

It would be cool if the @JsonProperty decorator could accept custom mapping functions.

For example:

const deserializeDate = dateString => moment(dateString).toDate();  // pretend this is valid momentjs syntax
const convertToStatusEnum = statusString => return enum[statusString] // fetches the appropriate enumerator

class Homework {
   @JsonProperty({name:  'date', mappingFn: deserializeDate })
   public dueDate: Date = null;

   @JsonProperty({mappingFn: convertToStatusEnum})
   public status: Statuses = Statuses.NotDone;
}

Hey

Do you have an example of how to use customConverter ?

export const dateConverter: ICustomConverter = {
     fromJson(data: any): any {
         return new Date(data);
     },

     toJson(data: Date): any {
         return data.toJSON();
     }
}
