Life of PI

Overview

The Life of PI is a Node.js application designed to calculate the value of Pi to an increasing number of decimal places with each request. It utilizes worker threads for asynchronous calculations and Redis for storing the results.

Architecture Diagram

This architecture efficiently handles Pi calculations and data retrieval by utilizing worker threads for computation and Redis for data storage. The use of asynchronous processing ensures that the application remains responsive, providing a seamless experience for the user.
