openapi-cop VS Superstruct

Json schema validation is cpu expensive in nodejs, so you do not want it in production for every request. We made a proxy [1] that only allows requests that are conform to the swagger json which is easy to hook between frontend and backend in dev-mode

You can check out Superstruct documentation here.

This is where I saw compiled folder has superstruct’s minified code.

However, working with the unknown type is less convenient than merely specifying the desired data type. Apart from type-casting, there are multiple ways to convert the unknown type into the required data type. One such method is utilizing the Superstruct library to validate data at runtime and throw detailed errors if the data is invalid.

For example, the superstruct library is a lighter alternative to Zod. This library is more suitable for use on the client side since it has a relatively small size (13.1 kB vs 3.4 kB).

Banditstash, like all the newer validation libraries (yup, zod, superstruct, typed) can auto-generate TS type from a JS schema:

Superstruct 1.0.3

Inside the action, the first thing we're going to do is get the formData using the request object. Then we will create an object from the formData data that will later be validated by our superstruct schema.

You could use Zod or Superstruct to validate the types of values, or use typestack/class-validator if it makes sense.
