Param	Type
`message`	`string`	Optional human-readable description of why the response was rejected.

Property	Type

Error thrown when a received HTTP response isn't OK.

Carries the response's HTTP status code (defaults to 400).

Thrown when a received response indicates an error — the HTTP 4xx/5xx range. Its .code property defaults to 400. Use it for a response that arrived but was unsuccessful, as distinct from a transport failure (NetworkError).

Usage

import { ResponseError } from "shelving/error";

function checkResponse(res: Response): void {
  if (!res.ok) throw new ResponseError(res.statusText, { code: res.status });
}

See shelving/error for shared behaviour — attaching context fields, caller trimming, and catching by type.

Examples

throw new ResponseError("Unexpected response body", { code: 422 });
