LED Calculator API - Frankenstein Category

"Bringing together disparate technologies into one powerful application"

Comment

LED Calculator API is a standalone Node.js + Express microservice that transforms existing frontend LED display configuration algorithms into a powerful RESTful API. This project exemplifies the "Frankenstein" spirit by stitching together:

  • Complex TypeScript algorithms (originally designed for React frontend)
  • Node.js/Express backend (API layer)
  • SVG generation engine (visual preview system)
  • Mathematical optimization (guillotine packing algorithm)
  • Image processing (PNG conversion with Sharp)

The Challenge We Solved

LED display wall configuration is a complex engineering problem:

  • Multiple cabinet sizes must fit together like puzzle pieces
  • Coverage must be maximized while maintaining structural integrity
  • Visual previews are essential for client approval
  • Third-party integrations need API access

Our Frankenstein creation takes algorithms that were trapped in a React frontend and gives them new life as a standalone API service that any application can consume.
