import * as mod from "https://deno.land/std@0.167.0/http/mod.ts";

Contains the enum Status which enumerates standard HTTP status codes and provides several type guards for handling status codes with type safety.

Examples

Example 1

import {
  Status,
  STATUS_TEXT,
} from "https://deno.land/std@0.167.0/http/http_status.ts";

console.log(Status.NotFound); //=> 404
console.log(STATUS_TEXT[Status.NotFound]); //=> "Not Found"

import { isErrorStatus } from "https://deno.land/std@0.167.0/http/http_status.ts";

const res = await fetch("https://example.com/");

if (isErrorStatus(res.status)) {
  // error handling here...
}

Classes

c CookieMap	Provides a way to manage cookies in a request and response on the server as a single iterable collection.
c HttpError	The base class that all derivative HTTP extend, providing a `status` and an `expose` property.
c SecureCookieMap	Provides an way to manage cookies in a request and response on the server as a single iterable collection, as well as the ability to sign and verify cookies to prevent tampering.
c Server	Used to construct an HTTP server.

Enums

Status

Standard HTTP status codes.

Variables

v cookieMapHeadersInitSymbol	Symbol which is used in mergeHeaders to extract a `[string \| string][]` from an instance to generate the final set of headers.
v errors	A namespace that contains each error constructor. Each error extends `HTTPError` and provides `.status` and `.expose` properties, where the `.status` will be an error `Status` value and `.expose` indicates if information, like a stack trace, should be shared in the response.
v STATUS_TEXT	A record of all the status codes text.

Functions

f accepts	Returns an array of media types accepted by the request, in order of preference. If there are no media types supplied in the request, then any media type selector will be returned.
f acceptsEncodings	Returns an array of content encodings accepted by the request, in order of preference. If there are no encoding supplied in the request, then `["*"]` is returned, implying any encoding is accepted.
f acceptsLanguages	Returns an array of languages accepted by the request, in order of preference. If there are no languages supplied in the request, then `["*"]` is returned, imply any language is accepted.
f createHttpError	A factory function which provides a way to create errors. It takes up to 3 arguments, the error `Status`, an message, which defaults to the status text and error options, which incudes the `expose` property to set the `.expose` value on the error.
f deleteCookie	Set the cookie header with empty value in the headers to delete it
f getCookies	Parse cookies of a header
f getSetCookies	Parse set-cookies of a header
f isClientErrorStatus	A type guard that determines if the status code is a client error.
f isErrorStatus	A type guard that determines if the status code is an error.
f isHttpError	A type guard that determines if the value is an HttpError or not.
f isInformationalStatus	A type guard that determines if the status code is informational.
f isRedirectStatus	A type guard that determines if the status code is a redirection.
f isServerErrorStatus	A type guard that determines if the status code is a server error.
f isSuccessfulStatus	A type guard that determines if the status code is successful.
f mergeHeaders	Allows merging of various sources of headers into a final set of headers which can be used in a `Response`.
f serve	Serves HTTP requests with the given handler.
f serveListener	Constructs a server, accepts incoming connections on the given listener, and handles requests on these connections with the given handler.
f serveTls	Serves HTTPS requests with the given handler.
f setCookie	Set the cookie header properly in the headers
