AI Insights
Zod is a TypeScript-first library for declaring and validating schemas, enabling developers to ensure data integrity at runtime. Its static type inference feature helps maintain type safety throughout TypeScript projects, making it a popular choice among developers.
When to use
- When you need to validate user input or API responses against a schema.
- When working in TypeScript and you want strong type safety with runtime validation.
- When performance is important, as Zod is lightweight (bundle size: 63.7 kB).
When NOT to use
- If you are working in a JavaScript environment without TypeScript support.
- If you require complex validation logic that might be clearer with a more feature-rich library.
- If the overhead of maintaining type definitions is undesirable for your project.
