Official @wthek Extension – Express Middleware for `http-error-kit`

Seamless Express Error Handling with @wthek

Built for applications powered by http-error-kit, this middleware ensures that all http-error-kit errors are properly formatted and returned with the correct HTTP status codes.

💡 What the HEK?! Need a hassle-free way to manage error responses for http-error-kit errors in Express? @wthek/express-middleware has got you covered!

Features

Official http-error-kit Extension – The recommended middleware for Express.js apps.
Auto-sets HTTP status codes – Ensures the response status matches the error type.
Plug-and-Play Middleware – Just drop it before starting your server!
Graceful Fallbacks – Passes unrecognized errors to the next middleware.

Installation

npm install @wthek/express-middleware

Usage

Add Middleware Just Before Starting the Server

To catch all errors correctly, place KitExpressMiddleware() after all routes but before starting your Express server.

import express from "express";
import { KitHttpError, BadRequestError } from "http-error-kit";
import { KitExpressMiddleware } from "@wthek/express-middleware";

const app = express();

// Routes
app.get("/", (req, res) => {
  throw new BadRequestError("Invalid request!");
});

// Error Handling Middleware (must be after routes)
app.use(KitExpressMiddleware());

// Start Server
app.listen(3000, () => {
  console.log("Server running on port 3000");
});

How It Works

Catches errors thrown in routes and middleware
Checks if the error is an instance of any http-error-kit Errors
Formats the error response and sets the correct HTTP status code
Passes other errors to the next middleware (so they can be handled separately)

Why Use `@wthek/express-middleware`?

No more manual error handling – Status codes are automatically set.
Consistent API responses – Standardized errors improve debugging & logging.
Works perfectly with http-error-kit – Fully compatible with existing http-error-kit error structures.
