creating a custom TypeScript type with multiple specific "criteria"

Exploring TypeScript to enhance the data solidity of my app. Isn't that its primary purpose?

I'm curious if it's doable to define a type with very precise properties:

  • should be an object
  • must contain zero or one properties
  • each key should be a URI
  • each value should be a URI

Can TypeScript accomplish this, and if so, how? If not, what alternative would you recommend for implementing such logic?

Appreciate your insights!

While Typescript provides type-safety at compile time, it does not offer validation during runtime. For a solution that includes runtime validation, consider exploring https://github.com/typestack/class-validator
