contract-typebox

To share API contracts using TypeBox, you define Type.Object schemas in a shared package and import them in Elysia backend routes and frontend validation flows to enforce runtime checks.

The best way to validate API payloads with TypeBox and Elysia is to import shared schemas from your contracts directory and apply them directly as route validators to prevent invalid data from flowing through services.

Runtime schema validation for shared TypeScript contracts works by applying TypeBox schemas to incoming data, ensuring payloads like User and Pagination conform to defined Type.Object structures before processing.

Yes, you can compose nested schemas for API contracts in TypeBox by structuring Type.Object exports with optional nested properties, enabling complex payload validation across shared frontend and backend flows.

You need TypeBox schemas alongside TypeScript because TypeScript only checks types at compile time, whereas TypeBox provides runtime validation to prevent invalid data from entering your API routes and UI layers.

TypeBox supports shared contract structures for pagination and auth by defining Type.Object schemas that centralize validation logic and reduce manual boilerplate across services.
