Creating HTTP Error Objects

This feature allows developers to create HTTP error objects with a status code and message. The example demonstrates creating a 404 Not Found error.

import createError from 'http-errors';

const NotFoundError = createError(404, 'This page does not exist.');
console.log(NotFoundError.status); // 404
console.log(NotFoundError.message); // 'This page does not exist.'

Type Checking for HTTP Error Objects

This feature provides type definitions for handling HTTP errors in a type-safe way. The example shows a function that accepts an HttpError object, demonstrating the use of TypeScript for type checking.

import createError, { HttpError } from 'http-errors';

function handleError(error: HttpError) {
  console.log(error.status);
  console.log(error.message);
}

const myError = createError(500, 'Internal Server Error');
handleError(myError);
