http

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

import { serve } from "https://deno.land/std@$STD_VERSION/http/server.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://0.0.0.0:4507/

Cookie

Helper to manipulate Cookie through ServerRequest and Response.

import { ServerRequest } from "https://deno.land/std@$STD_VERSION/http/server.ts";
import { getCookies } from "https://deno.land/std@$STD_VERSION/http/cookie.ts";

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

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

To set a Cookie you can add CookieOptions to properly set your Cookie:

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

let response: Response = {};
const cookie: Cookie = { name: "Space", value: "Cat" };
setCookie(response, cookie);

const cookieHeader = response.headers.get("set-cookie");
console.log("Set-Cookie:", cookieHeader);
// Set-Cookie: Space=Cat

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

import { Response } from "https://deno.land/std@$STD_VERSION/http/server.ts";
import { deleteCookie } from "https://deno.land/std@$STD_VERSION/http/cookie.ts";

let response: Response = {};
deleteCookie(response, "deno");

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

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