@ingeze/api-error/dist/handlers/fastify.d.ts

A TypeScript library for handling HTTP errors in Express, NestJS, and Fastify APIs.

import { FastifyReply, FastifyRequest } from 'fastify';
/**
 * Fastify middleware for handling errors in a Fastify application.
 * This middleware processes errors thrown during request handling, formatting them into a standardized JSON response.
 * If the error is an instance of `ErrorHandler`, it uses the error's status code and JSON representation.
 * Otherwise, it returns a generic 500 Internal Server Error response with a default message.
 *
 * @param err - The error object thrown during request processing.
 * @param req - The Fastify request object.
 * @param reply - The Fastify reply object used to send the response.
 * @returns void - This middleware does not return a value; it sends a response directly via the `reply` object.
 *
 * @example
 * ```typescript
 * import fastify from 'fastify';
 * import { fastifyErrorMiddleware } from '@ingeze/api-error';
 *
 * const app = fastify();
 * app.setErrorHandler(fastifyErrorMiddleware);
 * ```
