Cookie Management in Web Development

Cookie management libraries in JavaScript provide developers with tools to create, read, and delete cookies in a web browser. Cookies are small pieces of data stored on the client side, often used for session management, user tracking, and storing preferences. These libraries simplify cookie handling by providing easy-to-use APIs, ensuring proper encoding and decoding of cookie values, and handling issues like cookie expiration and path scoping. They are essential for building web applications that require persistent data storage on the client side.

README for cookie

cookie

NPM Version NPM Downloads Build Status Coverage Status

Basic HTTP cookie parser and serializer for HTTP servers.

Installation

$ npm install cookie

API

const cookie = require("cookie");
// import * as cookie from 'cookie';

cookie.parse(str, options)

Parse a HTTP Cookie header string and returning an object of all cookie name-value pairs. The str argument is the string representing a Cookie header value and options is an optional object containing additional parsing options.

const cookies = cookie.parse("foo=bar; equation=E%3Dmc%5E2");
// { foo: 'bar', equation: 'E=mc^2' }

Options

cookie.parse accepts these properties in the options object.

decode

Specifies a function that will be used to decode a cookie-value. Since the value of a cookie has a limited character set (and must be a simple string), this function can be used to decode a previously-encoded cookie value into a JavaScript string.

The default function is the global decodeURIComponent, wrapped in a try..catch. If an error is thrown it will return the cookie's original value. If you provide your own encode/decode scheme you must ensure errors are appropriately handled.

cookie.serialize(name, value, options)

Serialize a cookie name-value pair into a Set-Cookie header string. The name argument is the name for the cookie, the value argument is the value to set the cookie to, and the options argument is an optional object containing additional serialization options.

const setCookie = cookie.serialize("foo", "bar");
// foo=bar

Options

cookie.serialize accepts these properties in the options object.

encode

Specifies a function that will be used to encode a cookie-value. Since value of a cookie has a limited character set (and must be a simple string), this function can be used to encode a value into a string suited for a cookie's value, and should mirror decode when parsing.

The default function is the global encodeURIComponent.

maxAge

Specifies the number (in seconds) to be the value for the Max-Age Set-Cookie attribute.

The cookie storage model specification states that if both expires and maxAge are set, then maxAge takes precedence, but it is possible not all clients by obey this, so if both are set, they should point to the same date and time.

expires

Specifies the Date object to be the value for the Expires Set-Cookie attribute. When no expiration is set clients consider this a "non-persistent cookie" and delete it the current session is over.

The cookie storage model specification states that if both expires and maxAge are set, then maxAge takes precedence, but it is possible not all clients by obey this, so if both are set, they should point to the same date and time.

domain

Specifies the value for the Domain Set-Cookie attribute. When no domain is set clients consider the cookie to apply to the current domain only.

path

Specifies the value for the Path Set-Cookie attribute. When no path is set, the path is considered the "default path".

httpOnly

Enables the HttpOnly Set-Cookie attribute. When enabled, clients will not allow client-side JavaScript to see the cookie in document.cookie.

secure

Enables the Secure Set-Cookie attribute. When enabled, clients will only send the cookie back if the browser has a HTTPS connection.

partitioned

Enables the Partitioned Set-Cookie attribute. When enabled, clients will only send the cookie back when the current domain and top-level domain matches.

This is an attribute that has not yet been fully standardized, and may change in the future. This also means clients may ignore this attribute until they understand it. More information about can be found in the proposal.

priority

Specifies the value for the Priority Set-Cookie attribute.

  • 'low' will set the Priority attribute to Low.
  • 'medium' will set the Priority attribute to Medium, the default priority when not set.
  • 'high' will set the Priority attribute to High.

More information about priority levels can be found in the specification.

sameSite

Specifies the value for the SameSite Set-Cookie attribute.

  • true will set the SameSite attribute to Strict for strict same site enforcement.
  • 'lax' will set the SameSite attribute to Lax for lax same site enforcement.
  • 'none' will set the SameSite attribute to None for an explicit cross-site cookie.
  • 'strict' will set the SameSite attribute to Strict for strict same site enforcement.

More information about enforcement levels can be found in the specification.

Example

The following example uses this module in conjunction with the Node.js core HTTP server to prompt a user for their name and display it back on future visits.

var cookie = require("cookie");
var escapeHtml = require("escape-html");
var http = require("http");
var url = require("url");

function onRequest(req, res) {
  // Parse the query string
  var query = url.parse(req.url, true, true).query;

  if (query && query.name) {
    // Set a new cookie with the name
    res.setHeader(
      "Set-Cookie",
      cookie.serialize("name", String(query.name), {
        httpOnly: true,
        maxAge: 60 * 60 * 24 * 7, // 1 week
      }),
    );

    // Redirect back after setting cookie
    res.statusCode = 302;
    res.setHeader("Location", req.headers.referer || "/");
    res.end();
    return;
  }

  // Parse the cookies on the request
  var cookies = cookie.parse(req.headers.cookie || "");

  // Get the visitor name set in the cookie
  var name = cookies.name;

  res.setHeader("Content-Type", "text/html; charset=UTF-8");

  if (name) {
    res.write("<p>Welcome back, <b>" + escapeHtml(name) + "</b>!</p>");
  } else {
    res.write("<p>Hello, new visitor!</p>");
  }

  res.write('<form method="GET">');
  res.write(
    '<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">',
  );
  res.end("</form>");
}

http.createServer(onRequest).listen(3000);
