@alwatr/fetch/dist/error.d.ts

`@alwatr/fetch` is an enhanced, lightweight, and dependency-free wrapper for the native `fetch` API. It provides modern features like caching strategies, request retries, timeouts, and intelligent duplicate request handling, all in a compact package.

import type { FetchErrorReason } from "./type.js";
/**
 * Custom error class for fetch-related failures.
 *
 * This error is thrown when a fetch request fails, either due to a network issue
 * or an HTTP error status (i.e., `response.ok` is `false`). It enriches the
 * standard `Error` object with the `response` and the parsed `data` from the
 * response body, allowing for more detailed error handling.
 *
 * @example
 * ```typescript
 * const [response, error] = await fetch('/api/endpoint');
 * if (error) {
 *   console.error(`Request failed with status ${error.response?.status}`);
 *   console.error('Server response:', error.data);
 * }
 * ```
