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.
