ValidationAPIProviderclass

Provider that validates payloads and results against the endpoint's schemas, so a source of any type is made type-safe.

• Payload validation errors bubble up as user-readable strings; result validation errors are wrapped in ResponseError.

A wrapping provider that validates data against the endpoint's shelving/schema. ValidationAPIProvider validates the payload before the request is built and validates the result after the response is parsed — so a malformed payload is caught before it leaves, and a bad response surfaces as a clear error.

Place it just inside the network provider so everything above it works with validated, typed data.

Usage

import { ClientAPIProvider, ValidationAPIProvider } from "shelving/api"

const provider = new ValidationAPIProvider(
  new ClientAPIProvider({ url: "https://api.example.com" })
)

// Payload validated against the endpoint's payload schema before sending;
// result validated against its result schema before returning.
const user = await provider.call(getUser, { id: "u_123" })
