End-to-end type safety is a feeling
Placeholder post — replace with your own writing.
There’s a specific kind of calm that comes from a codebase where the types flow all the way through: rename a field on the server, and the client stops compiling until you fix it. No runtime surprise, no stale contract.
The good
- Refactors become mechanical. The compiler is your checklist.
- Onboarding speeds up — the types are the docs.
The honest tradeoffs
- Build complexity goes up. You’re buying safety with tooling.
- It shines for internal, fast-moving APIs; it matters less at stable public boundaries where versioning is the real concern.
Used where it fits, it’s one of the highest-leverage choices a small team can make.
