    There are more improvements we could make, but we should have a basic understanding of why it might be useful to validate any external data at runtime. io-ts offers more features handling recursive and optional types. Furthermore there are libraries like io-ts-promise that provide more features and useful helpers, the above decodePromise, for example, is available in a more advanced variant via io-ts-promise.

  • How do you handle runtime validation / API documentation?

    You could try zod for runtime validation and types with zod-openapi to derive open API schema from the validator. An example of the alternative approach is something like generate-runtypes or runtyping to generate runtypes validators from a JSON schema (and separately generate the Open API definitions from the JSON schema).
