## What it is
TypeBox is a TypeScript library for building JSON Schema objects that also infer as static TypeScript types. It provides a unified runtime and compile-time type system for validating data in REST and RPC services.

## Use cases
- build  schemas in typescript
- validate request payloads at runtime
- infer typescript types from schemas
- validate data received over the wire in rpc services
- define shared schemas for api contracts

## When to choose
- you need JSON Schema validation with matching static TypeScript types
- you want a single schema definition usable at runtime and compile time
- you are building REST or RPC services that validate incoming data

## When to avoid
- you only need compile-time types with no runtime validation
- your project does not use TypeScript or JSON Schema

## Facets
- artifact type: library
- maturity: stable
- function: serialization, type-system, developer-tools
- domain: developer-tools, apis, web-development
- platform: cross-platform
- tags: -schema, runtime-validation, static-types, schema-builder, nodejs, typescript
