npm install @wthek/express-middlewareAdd 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");
});- Catches errors thrown in routes and middleware
- Checks if the error is an instance of any
http-error-kitErrors - Formats the error response and sets the correct HTTP status code
- Passes other errors to the next middleware (so they can be handled separately)
- No more manual error handling – Status codes are automatically set.
- Consistent API responses – Standardized errors improve debugging & logging.
