interface CookieMapOptions
import { type CookieMapOptions } from "https://deno.land/std@0.158.0/http/mod.ts";

Provides a iterable map interfaces for managing cookies server side.

Examples

To access the keys in a request and have any set keys available for creating a response:

import {
  CookieMap,
  mergeHeaders
} from "https://deno.land/std@0.158.0/http/cookie_map.ts";

const request = new Request("https://localhost/", {
  headers: { "cookie": "foo=bar; bar=baz;"}
});

const cookies = new CookieMap(request, { secure: true });
console.log(cookies.get("foo")); // logs "bar"
cookies.set("session", "1234567", { secure: true });

const response = new Response("hello", {
  headers: mergeHeaders({
    "content-type": "text/plain",
  }, cookies),
});

To have automatic management of cryptographically signed cookies, you can use the SecureCookieMap instead of CookieMap. The biggest difference is that the methods operate async in order to be able to support async signing and validation of cookies:

import {
  SecureCookieMap,
  mergeHeaders,
  type KeyRing,
} from "https://deno.land/std@0.158.0/http/cookie_map.ts";

const request = new Request("https://localhost/", {
  headers: { "cookie": "foo=bar; bar=baz;"}
});

// The keys must implement the `KeyRing` interface.
declare const keys: KeyRing;

const cookies = new SecureCookieMap(request, { keys, secure: true });
console.log(await cookies.get("foo")); // logs "bar"
// the cookie will be automatically signed using the supplied key ring.
await cookies.set("session", "1234567");

const response = new Response("hello", {
  headers: mergeHeaders({
    "content-type": "text/plain",
  }, cookies),
});

In addition, if you have a Response or Headers for a response at construction of the cookies object, they can be passed and any set cookies will be added directly to those headers:

import { CookieMap } from "https://deno.land/std@0.158.0/http/cookie_map.ts";

const request = new Request("https://localhost/", {
  headers: { "cookie": "foo=bar; bar=baz;"}
});

const response = new Response("hello", {
  headers: { "content-type": "text/plain" },
});

const cookies = new CookieMap(request, { response });
console.log(cookies.get("foo")); // logs "bar"
cookies.set("session", "1234567");

Properties

optional
response: Headered | Headers

The Response or the headers that will be used with the response. When provided, Set-Cookie headers will be set in the headers when cookies are set or deleted in the map.

An alternative way to extract the headers is to pass the cookie map to the mergeHeaders function to merge various sources of the headers to be provided when creating or updating a response.

optional
secure: boolean

A flag that indicates if the request and response are being handled over a secure (e.g. HTTPS/TLS) connection. Defaults to false.
