[API reference](https://evolu.dev/docs/api-reference) › [@evolu/common](https://evolu.dev/docs/api-reference/common) › StandardSchema

The Standard Schema interface, which every [Type](https://evolu.dev/docs/api-reference/common/Type/interfaces/Type) implements and schema
columns accept, so Evolu Types work in libraries that accept Standard Schema,
and other libraries' validators work as column types.
