http

http is a module to provide HTTP client and server implementations.

Server

Server APIs utilizing Deno’s HTTP server APIs.

import { listenAndServe } from "https://deno.land/std@0.108.0/http/server.ts";

listenAndServe(":8000", () => new Response("Hello World\n"));

console.log("http://localhost:8000/");

Legacy Server (Deprecated)

Legacy server APIs using a JavaScript HTTP server implementation.

import { serve } from "https://deno.land/std@0.108.0/http/server_legacy.ts";

const server = serve({ port: 8000 });
console.log("http://localhost:8000/");

for await (const req of server) {
  req.respond({ body: "Hello World\n" });
}

File Server

A small program for serving local files over HTTP.

deno run --allow-net --allow-read https://deno.land/std/http/file_server.ts
> HTTP server listening on http://localhost:4507/

Helpers to manipulate the Cookie header.

getCookies

import { getCookies } from "https://deno.land/std@0.108.0/http/cookie.ts";

const headers = new Headers();
headers.set("Cookie", "full=of; tasty=chocolate");

const cookies = getCookies(headers);
console.log(cookies); // { full: "of", tasty: "chocolate" }

setCookie

import {
  Cookie,
  setCookie,
} from "https://deno.land/std@0.108.0/http/cookie.ts";

const headers = new Headers();
const cookie: Cookie = { name: "Space", value: "Cat" };
setCookie(headers, cookie);

const cookieHeader = headers.get("set-cookie");
console.log(cookieHeader); // Space=Cat

deleteCookie

Note: Deleting a Cookie will set its expiration date before now. Forcing the browser to delete it.

import { deleteCookie } from "https://deno.land/std@0.108.0/http/cookie.ts";

const headers = new Headers();
deleteCookie(headers, "deno");

const cookieHeader = headers.get("set-cookie");
console.log(cookieHeader); // deno=; Expires=Thus, 01 Jan 1970 00:00:00 GMT

Note: It is possible to pass the exact same path and domain attributes that were used to set the cookie.

import { deleteCookie } from "https://deno.land/std@0.108.0/http/cookie.ts";

const headers = new Headers();
deleteCookie(headers, "deno", { path: "/", domain: "deno.land" });

Note: At the moment multiple Set-Cookie in a Response is not handled.
