Portfolio

React State Management Library

Redux State Manager is a library written on top of Redux-Saga that removes boilerplate code and provides and intuitive mode to call APIs, receive WebSocket messages, and manipulate state data.I decided to create a configurable interface over it that works and allows you to focus on fast development instead of moving chunks of code from one file to another.
