# PF-Flask-REST

Problem Fighter Flask Representational State Transfer (PF-Flask-REST) library is build for rapid API development & Monolithic 
application development. It has useful class and methods which allow developer to build set of CRUD API end points within 5 minutes. 
Automatic Data validation, Data processing, & Data CRUD with Database. Letâ€™s see what is waiting for us.
