Summary

In this chapter, you followed the lifecycle of a TypeScript system after its initial success. You began with a fast proof of concept where frontend and backend matched only by assumption. When the backend response evolved, the frontend broke at runtime because TypeScript had nothing concrete to enforce.

By introducing shared contracts, you transformed implicit agreements into explicit code. By adding a small runtime gate at the JSON boundary, you acknowledged that network data is unknown until validated, and prevented corrupted shapes from leaking into your system. As collaboration and complexity increased, you applied patterns to create stable boundaries and advanced TypeScript features to make valid states explicit. Provider interfaces prevented vendor details from leaking across layers. Discriminated unions replaced fragile optional fields and forced exhaustive handling as the contract evolved. Typed API clients eliminated unsafe casts and removed an entire category of invisible...
