Choosing Configs
Explore techniques for managing multiple configuration layers in TypeScript applications using fp-ts constructs like Alt, Alternative, and Monoids. Understand how to combine fallback settings elegantly without complex conditionals to enhance your reservation app. This lesson helps you implement clear config precedence for basic, system, and user settings.
We'll cover the following...
