@inrupt/solid-client-errors is a JavaScript library for handling RFC9457 Problem Details on HTTP error responses.

This feature is currently available in ESS. Servers implementing RFC9457 Problem Details will be supported too.

Our JavaScript Client Libraries use relatively modern JavaScript, aligned with the ES2020 Specification features, we ship both ESM and CommonJS, with type definitions for TypeScript alongside.

This means that out of the box, we only support environments (browsers or runtimes) that were released after mid-2020, if you wish to target other (older) environments, then you will need to cross-compile our SDKs via the use of Babel, webpack, SWC, or similar.

If you need support for Internet Explorer, it is recommended to pass them through a tool like Babel, and to add polyfills for e.g. Map, Set, Promise, Headers, Array.prototype.includes, Object.entries and String.prototype.endsWith.

See Inrupt Solid Javascript Client Libraries.

For the latest stable version of solid-client-errors:

npm install @inrupt/solid-client-errors

Integrators of this library will generally use the following pattern to throw a subclass of ClientHttpError, corresponding to the response status.

import { handleErrorResponse } from "@inrupt/solid-client-errors";

const response = await fetch(url, options);

if (response.status !== 200) {
  const responseBody = await response.text();
  throw handleErrorResponse(
    response,
    responseBody,
    "application error message",
  );
}

The specific error type corresponds to the HTTP status code in the response, each of which implements the WithProblemDetails type.

• 400: BadRequestError
• 401: UnauthorizedError
• 403: ForbiddenError
• 404: NotFoundError
• 405: MethodNotAllowedError
• 406: NotAcceptableError
• 409: ConflictError
• 410: GoneError
• 412: PreconditionFailedError
• 415: UnsupportedMediaTypeError
• 429: TooManyRequestsError
• 500: InternalServerError

Each error includes a problemDetails field with the following properties:

• type: URL: The specific error type. By default, this is about:blank.
• title: string: A short description of the problem.
• status: number: The error response status code.
• detail?: string: A longer description of the problem.
• instance?: URL: A unique URL identifying the problem occurrence.

Consumers of these errors may handle the ProblemDetails data in the following way:

const res = await getFile(url, options)
  .then((file) => { /* Do something after a successful request */ }
  .catch((err) => {
    if (hasProblemDetails(err)) {
      const problems = err.problemDetails;
      /* Do something with the details of the failed request */
    } else {
      /* Do something with a generic error message */
    }
  });
