A collection of HTTP errors and utilities.

The export errors contains an individual class that extends HttpError which makes handling HTTP errors in a structured way.

The function createHttpError provides a way to create instances of errors in a factory pattern.

The function isHttpError is a type guard that will narrow a value to an HttpError instance.

import * as netzo from "https://deno.land/x/netzo@0.3.66/deps/std/http/http_errors.ts";
