FAQPage Schema
How do I validate JSON payloads in TypeScript at runtime?▼

You can validate JSON payloads at runtime by defining type-safe schemas using ArkType's TypeScript-native syntax. This allows you to ensure incoming data matches your expected structure before it reaches your business logic.

What is the best way to validate environment variables in a TypeScript application?▼

Validating environment variables is handled using ArkEnv, which securely validates and coerces environment configuration. This ensures your application starts only with correctly typed and structured configuration data.

Can I define complex TypeScript schemas using string expressions?▼

Yes, you can define complex data schemas using familiar TypeScript-like string expressions. ArkType supports advanced schema features including morphs, scopes, and generics for transforming and validating data.

Does runtime validation with ArkType require external dependencies?▼

No, ArkType runtime validation operates as a TypeScript-native schema definition library with no external dependencies. It integrates directly into your existing TypeScript stack to catch invalid inputs early.
