Automatically Disable Tracking

Unlike other cookie consent managers and React components, this component automatically disables tracking for Google Analytics, Facebook Pixel, and other tracking services. This is done by blocking the tracking scripts from loading. Therefore, you don't need to manually disable tracking, saving you hours of work.

Embedded Content Blocking

React Cookie Manager automatically blocks embedded iframes that would otherwise load cookies without consent, such as:

• YouTube videos
• Vimeo videos
• Google Maps
• Social media embeds (Twitter, Instagram, etc.)
• Third-party widgets and tools

When a user hasn't consented to the required cookies, these embeds are replaced with user-friendly placeholders that:

• Explain why the content is blocked
• Provide a button to manage cookie settings
• Inform users to refresh the page after accepting cookies
• Maintain the same dimensions as the original content

This ensures your site remains GDPR-compliant while providing a seamless user experience.

Installation

npm install react-cookie-manager
# or
yarn add react-cookie-manager

Importing Styles

The component requires its CSS file to be imported in your application. Add the following import to your app's entry point (e.g., App.tsx or index.tsx):

import "react-cookie-manager/style.css";

Basic Usage

import { CookieManager } from "react-cookie-manager";
import "react-cookie-manager/style.css";

function App() {
  return (
    <CookieManager
      translations={{
        title: "Cookie Preferences",
        message: "We use cookies to improve your experience.",
      }}
      onManage={(preferences) =>
        console.log("Cookie preferences:", preferences)
      }
    >
      <YourApp />
    </CookieManager>
  );
}

Next.js Usage

For Next.js applications, you'll need to use dynamic imports to prevent SSR of the cookie manager:

"use client";

import dynamic from "next/dynamic";

const CookieManager = dynamic(
  () => import("react-cookie-manager").then((mod) => mod.CookieManager),
  { ssr: false, loading: () => null }
);

// In your Providers component or layout
export function Providers({ children }: { children: React.ReactNode }) {
  return (
    <CookieManager
      showManageButton={true}
      translations={{
        title: "Cookie Preferences",
        message: "We use cookies to improve your experience.",
      }}
      displayType="banner"
      theme="light"
    >
      {children}
    </CookieManager>
  );
}

// In your page component
import { useCookieConsent } from "react-cookie-manager";

export default function Home() {
  const { showConsentBanner, detailedConsent } = useCookieConsent();

  return (
    <div>
      <button onClick={showConsentBanner}>Manage Cookie Settings</button>
      {detailedConsent && (
        <div>
          Analytics:{" "}
          {detailedConsent.Analytics.consented ? "Enabled" : "Disabled"}
          Social: {detailedConsent.Social.consented ? "Enabled" : "Disabled"}
          Advertising:{" "}
          {detailedConsent.Advertising.consented ? "Enabled" : "Disabled"}
        </div>
      )}
    </div>
  );
}

Full Usage

import { CookieManager } from "react-cookie-manager";
import "react-cookie-manager/style.css";

function App() {
  return (
    <CookieManager
      translations={{
        title: "Would You Like A Cookie? 🍪",
        message:
          "We value your privacy. Choose which cookies you want to allow. Essential cookies are always enabled as they are necessary for the website to function properly.",
        buttonText: "Accept All",
        declineButtonText: "Decline All",
        manageButtonText: "Manage Cookies",
        privacyPolicyText: "Privacy Policy",
      }}
      showManageButton={true}
      privacyPolicyUrl="https://example.com/privacy"
      theme="light"
      displayType="popup"
      cookieKitId="" // Optional: Enable CookieKit.io integration
      onManage={(preferences) => {
        if (preferences) {
          console.log("Cookie preferences updated:", preferences);
        }
      }}
      onAccept={() => {
        console.log("User accepted all cookies");
        // Analytics tracking can be initialized here
      }}
      onDecline={() => {
        console.log("User declined all cookies");
        // Handle declined state if needed
      }}
    >
      <AppContent />
    </CookieManager>
  );
}

Advanced Usage with Hook

import { CookieManager, useCookieConsent } from "react-cookie-manager";

function CookieSettings() {
  const { showConsentBanner, detailedConsent } = useCookieConsent();

  return (
    <div>
      <button onClick={showConsentBanner}>Manage Cookie Settings</button>
      {detailedConsent && (
        <div>
          Analytics:{" "}
          {detailedConsent.Analytics.consented ? "Enabled" : "Disabled"}
          Social: {detailedConsent.Social.consented ? "Enabled" : "Disabled"}
          Advertising:{" "}
          {detailedConsent.Advertising.consented ? "Enabled" : "Disabled"}
        </div>
      )}
    </div>
  );
}

Floating Cookie Button

The floating cookie button provides a persistent, accessible way for users to manage their cookie preferences after they've made their initial choice. It appears as a small, animated cookie icon in the bottom-left corner of the screen.

Enabling the Floating Button

  enableFloatingButton={true}
  theme="light" // or "dark"
  // ... other props
>
  <YourApp />
</CookieManager>

}

Event Callbacks

The CookieManager component provides callback props that allow you to respond to user interactions with the consent UI:

Usage Example

<CookieManager
  onAccept={() => {
    console.log("All cookies accepted");
    // Initialize analytics tools
    window.gtag?.("consent", "update", { analytics_storage: "granted" });
  }}
  onDecline={() => {
    console.log("All cookies declined");
    // Ensure tracking is disabled
    window.gtag?.("consent", "update", { analytics_storage: "denied" });
  }}
  onManage={(preferences) => {
    console.log("Custom preferences saved:", preferences);
    // Handle granular consent
    if (preferences?.Analytics) {
      // Enable analytics
    }
    if (preferences?.Advertising) {
      // Enable ad personalization
    }
  }}
>
  {children}
</CookieManager>

Common Use Cases

• Analytics Initialization: Only initialize tracking tools after receiving explicit consent
• Ad Personalization: Enable or disable personalized advertising based on user preferences
• Social Media Integration: Load social widgets only when Social cookies are accepted
• Consent Logging: Record user consent choices for compliance purposes
• UI Updates: Update the UI based on user consent status (e.g., showing alternative content)

i18next support

import { default as i18next } from "i18next";

function App() {
  return (
    <CookieManager
      translations={i18next.t}
      translationI18NextPrefix="cookies."
      ...
      />
  )
}

// en.json
{
  "cookies": {
    "title": "Would You Like A Cookie? 🍪",
    "message": "We value your privacy. Choose which cookies you want to allow. Essential cookies are always enabled as they are necessary for the website to function properly.",
    "buttonText": "Accept All",
    "declineButtonText": "Decline All",
    "manageButtonText": "Manage Cookies",
    "privacyPolicyText": "Privacy Policy"
  }
  //...
}

Translation Options

All available translation keys and their default values:

{
  // Main consent banner/popup/modal
  title: "",  // Optional title
  message: "This website uses cookies to enhance your experience.",
  buttonText: "Accept",
  declineButtonText: "Decline",
  manageButtonText: "Manage Cookies",
  privacyPolicyText: "Privacy Policy",

  // Manage consent modal
  manageTitle: "Cookie Preferences",
  manageMessage: "Manage your cookie preferences below. Essential cookies are always enabled as they are necessary for the website to function properly.",

  // Essential cookies section
  manageEssentialTitle: "Essential",
  manageEssentialSubtitle: "Required for the website to function properly",
  manageEssentialStatus: "Status: Always enabled",
  manageEssentialStatusButtonText: "Always On",

  // Analytics cookies section
  manageAnalyticsTitle: "Analytics",
  manageAnalyticsSubtitle: "Help us understand how visitors interact with our website",

  // Social cookies section

  manageCookiesStatusConsented: "Consented",
  manageCookiesStatusDeclined: "Declined",

  // Buttons in manage modal
  manageCancelButtonText: "Cancel",
  manageSaveButtonText: "Save Preferences"
}

You can override any of these translations by passing them in the translations prop:

<CookieManager
  translations={{
    title: "Cookie Settings 🍪",
    message: "We use cookies to improve your experience.",
    buttonText: "Allow All",
    manageButtonText: "Customize",
    // ... override any other translations
  }}
>
  <App />
</CookieManager>

i18next Integration

When using i18next, make sure your translation files include all the keys under your chosen prefix:

{
  "cookies": {
    "title": "Cookie Settings 🍪",
    "message": "We use cookies to improve your experience.",
    "buttonText": "Allow All",
    "declineButtonText": "Decline All",
    "manageButtonText": "Customize",
    "privacyPolicyText": "Privacy Policy",
    "manageTitle": "Cookie Preferences",
    "manageMessage": "Customize your cookie preferences below...",
    "manageEssentialTitle": "Essential Cookies"
    // ... include all other translation keys
  }
}

Then use it with the i18next translation function:

import { useTranslation } from "react-i18next";

function App() {
  const { t } = useTranslation();

  return (
    <CookieManager translations={t} translationI18NextPrefix="cookies.">
      <YourApp />
    </CookieManager>
  );
}
