Runtime Validation in TypeScript: Where Zod Ends and the Type System Begins
📰 Dev.to · Gabriel Anhaia
Learn how to use Zod for runtime validation in TypeScript and understand where it complements the type system
Action Steps
- Use Zod to define schemas for external data
- Parse incoming data at the boundary using Zod
- Infer the type of parsed data and use it within your application
- Trust the inferred type throughout your codebase, relying on the type system for internal validation
Who Needs to Know This
Developers working with TypeScript and external data can benefit from using Zod for runtime validation, ensuring data integrity and security
Key Insight
💡 Zod and the type system serve different purposes: Zod validates external data at runtime, while the type system ensures internal code correctness
