Form Data Class For Transforming complex Objects into Form Data

With O2F, you can:

• Create FormData from Complex Data Structures for use in HTTP Methods.
• Convert Files nested within Objects/Arrays
• POST/PATCH Objects of any size

Why you should use Object-2-FormData

O2F is an Object Class that recursively traverses Objects neatly into FormData in such a way that they are exactly represented when parsed on the backend. This includes: Files, Arrays, Objects, & Primitive Data-Types.
