React is a library for declaratively specifying user interfaces. Jotai is a complementary library for declaratively modeling state in a monadic way. When these are used purposefully, what arises is a very sane MVC architecture built with boring technology [1].
Designing a type-safe plugin system in TypeScript that maintains strong typing guarantees while allowing extensible functionality. Using discriminated unions and generic constraints, we can build plugin architectures where registerPlugin<T extends Plugin>() enforces interface contracts at compile time. This approach enables dynamic feature extension while preserving full IDE support and preventing runtime type errors - useful for maintaining large-scale extensible applications.
