FibApp - An (overcomplicated) Fibonacci Calculator

FibApp is a purposefully overengineered, multi-service application created to learn, experiment with, and explore foundational concepts in modern web development. 🚀

Much of the inspiration for this project comes from Docker and Kubernetes - The Complete Guide by Stephen Grider. For those aiming to master Docker and Kubernetes, this resource is highly recommended.

🌐 Application Overview

• Redis Cache — an in-memory data structure store, used as a cache and message broker.
• API Service — Node.js + Express app that stores and retrieves Fibonacci numbers from Redis.
• Worker — Node.js process that listens on Redis Pub/Sub, computes Fibonacci numbers, and caches results in Redis.
• React Server — React application built with vite and styled with Pico CSS.

📂 Monorepo Setup with Turborepo

The repository is organized as a monorepo using Turborepo to manage multiple services and projects.

Key benefits of using Turborepo

• Efficient Builds: Caches and optimizes tasks to speed up development.
• Unified Management: Centralizes scripts and dependencies for consistent tooling.
• Scalability: Easily add new services or utilities without complicating the setup.

Apps, Packages and Technologies

• @repo/eslint-config: eslint configurations (includes eslint-plugin-prettier)
• @repo/typescript-config: tsconfig.jsons used throughout the monorepo
• @repo/vitest-config: vitest configurations, for react and node

This Turborepo has some additional tools already setup:

• Pnpm as the package manager
• TypeScript for static type checking
• ESLint & Prettier for code quality

Make sure the following are installed on your machine:

• Node.js — a JS runtime
• Docker — containerization platform
