πͺ React Cookie Manager
Privacy-first, flexible cookie consent for React. Automatically block trackers, manage granular consent, and provide a beautiful UX in a few lines of code.

Feature highlights
- Automatic blocking of common trackers and third-party embeds
- Granular categories (Analytics, Social, Advertising)
- Beautiful, responsive UI (banner, popup, modal) with theming
- Floating settings button and full preferences UI
Quick Start
Get up and running quickly with React Cookie Manager:
npm install react-cookie-manager
# or
yarn add react-cookie-managerimport { CookieManager } from "react-cookie-manager";
createRoot(document.getElementById("root")).render(
<StrictMode>
<CookieManager>
<App />
</CookieManager>
</StrictMode>
);The CookieManager component needs to wrap your entire application to properly manage cookie consent across all components and pages. Styles are automatically injected; no manual CSS import is required.

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.
Google Consent Mode v2
If you use Google Analytics 4 or Google Ads, enable Google Consent Mode v2 with a single prop. The library emits a denied-by-default state on mount and pushes a gtag('consent', 'update', β¦) whenever the user accepts, declines, or saves preferences β no manual wiring required.
import { CookieManager } from "react-cookie-manager";
<CookieManager googleConsentMode>
<App />
</CookieManager>;
// or with options
<CookieManager
googleConsentMode={{
waitForUpdate: 500, // ms Google waits for an update before pinging (default 500)
urlPassthrough: true, // gtag('set', 'url_passthrough', true)
adsDataRedaction: true, // gtag('set', 'ads_data_redaction', true)
}}
>
<App />
</CookieManager>;How categories map to Google signals
| Google signal | Cookie category |
| ------------------------- | ------------------ |
| analytics_storage | Analytics |
| ad_storage | Advertising |
| ad_user_data | Advertising |
| ad_personalization | Advertising |
| personalization_storage | Social |
| functionality_storage | always granted |
| security_storage | always granted |
A category that is hidden (via cookieCategories) or not consented maps to denied. Override any mapping or default with the options object:
<CookieManager
googleConsentMode={{
mapping: { personalization_storage: "Advertising" },
defaults: { analytics_storage: "granted" },
}}
>Loading the default before Google tags (strict ordering)
Consent Mode prefers the default command to run before the Google tag loads. Since the React provider mounts after <head> scripts, all commands are pushed to window.dataLayer (so Google still applies them, and wait_for_update covers the gap). For strict ordering, call the exported helper in <head> before your gtag snippet, then keep the googleConsentMode prop for updates:
<script>
// before the gtag.js snippet
</script>
<script type="module">
import { setGoogleConsentDefault } from "react-cookie-manager";
setGoogleConsentDefault();
</script>The exported updateGoogleConsent(preferences, options?) and mapConsentToSignals(preferences, options?) helpers are available for fully manual control as well.
Basic Usage
import { CookieManager } from "react-cookie-manager";
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
With Next.js (App Router), render CookieManager in a client Providers component at the root. No dynamic import is required.
// app/components/Providers.tsx
"use client";
import { CookieManager } from "react-cookie-manager";
export function Providers({ children }: { children: React.ReactNode }) {
return (
<CookieManager
showManageButton
enableFloatingButton
displayType="popup"
theme="light"
>
{children}
</CookieManager>
);
}// app/layout.tsx
import type { Metadata } from "next";
import { Providers } from "@/components/Providers";
export const metadata: Metadata = { title: "App" };
export default function RootLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<html lang="en">
<body>
<Providers>{children}</Providers>
</body>
</html>
);
}Use the hook in any client component:
// app/page.tsx (client component)
"use client";
import { useCookieConsent } from "react-cookie-manager";
export default function Home() {
const { showConsentBanner, detailedConsent, openPreferencesModal } =
useCookieConsent();
return (
<div>
<button onClick={showConsentBanner}>Manage Cookie Settings</button>
<button onClick={openPreferencesModal}>Open Preferences</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";
function App() {
return (
<CookieManager
translations={{
title: "Would You Like A Cookie? πͺ",
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"
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.

enableFloatingButton={true}
theme="light" // or "dark"
// ... other props
>
<YourApp />
</CookieManager>Features
- π― Automatically appears after initial consent
- π¨ Matches your theme (light/dark mode)
- π Smooth animations and hover effects
- β Dismissible with a close button
- π± Responsive and mobile-friendly
- ποΈ Easy access to cookie preferences
Behavior
- The button appears after users make their initial cookie choice
- Hovering reveals a close button to dismiss the floating button
- Clicking opens the cookie preferences modal

Other Elements

Cookie Categories
The component supports managing consent for three predefined cookie categories:
interface CookieCategories {
Analytics: boolean;
Social: boolean;
Advertising: boolean;
}You can control which categories appear in the Manage Preferences UI by using the cookieCategories prop. This allows you to selectively hide or show specific categories based on your needs:
<CookieManager
cookieCategories={{
Analytics: true, // Show Analytics category
Social: false, // Hide Social category
Advertising: true, // Show Advertising category
}}
>
{children}
</CookieManager>By default, all categories are shown. When a category is hidden, its initial value is still respected as defined in the initialPreferences prop. The default preferences are:
{
Analytics: false,
Social: false,
Advertising: false,
}This means even hidden categories will retain their configured initial values and can still be programmatically accessed.
Custom Categories
Beyond the three built-ins you can define your own categories with the categories prop. The built-ins (Analytics, Social, Advertising) are kept by default β passing a definition with a built-in id overrides its copy/domains, and any other id adds a custom category.
import { CookieManager } from "react-cookie-manager";
<CookieManager
categories={[
// Override a built-in's copy (optional):
{ id: "Analytics", description: "Helps us improve the product" },
// Add custom categories:
{
id: "marketing",
title: "Marketing",
description: "Personalised offers and campaigns",
trackerDomains: ["ads.example.com", "track.partner.com"],
defaultConsent: false,
},
{ id: "functional", title: "Functional", description: "Remember your settings" },
]}
>
{children}
</CookieManager>;CategoryDefinition:
interface CategoryDefinition {
id: string; // consent key; built-ins: "Analytics" | "Social" | "Advertising"
title?: string; // display title (built-ins fall back to their translation key)
description?: string; // sub-text
defaultConsent?: boolean; // initial toggle value (default false)
essential?: boolean; // render as an always-on row (no toggle)
trackerDomains?: string[]; // hosts/keywords blocked when this category is declined
}- Persistence & callbacks: custom categories are stored in the consent cookie under their
idand included in theonManage/useCookieConsent().detailedConsentdata, e.g.detailedConsent.marketing.consented. - Blocking: when a category is declined (or before consent), every host/keyword in its
trackerDomainsis blocked automatically β this is additive to the built-in blocklists. - Google Consent Mode: the built-in mapping is unchanged; custom categories are not mapped to Google signals by default.
Hook API
The useCookieConsent hook provides the following:
interface CookieConsentHook {
hasConsent: boolean | null;
isDeclined: boolean;
detailedConsent: DetailedCookieConsent | null;
showConsentBanner: () => void;
openPreferencesModal: () => void;
acceptCookies: () => void;
declineCookies: () => void;
updateDetailedConsent: (preferences: CookieCategories) => void;
}Event Callbacks
The CookieManager component provides callback props that allow you to respond to user interactions with the consent UI:
| Callback | Triggered when | Parameters |
| ----------------- | ------------------------------------------------------- | --------------------------------------- |
| onAccept | User accepts all cookies | None |
| onDecline | User declines all cookies | None |
| onManage | User saves custom cookie preferences | preferences?: CookieCategories |
| onConsentLoaded | Once on mount, with consent restored from storage | consent: DetailedCookieConsent \| null |
onConsentLoadedlets you sync analytics on page load when consent was already given on a previous visit (the interaction callbacks only fire when the user interacts). It receivesnullwhen no prior consent decision exists.
<CookieManager
onConsentLoaded={(consent) => {
if (consent?.Analytics.consented) {
window.gtag?.("consent", "update", { analytics_storage: "granted" });
}
}}
>
{children}
</CookieManager>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)

}You can override any of these translations by passing them in the translations prop:
<CookieManager
translations={{
title: "Cookie Settings πͺ",
message: "We use cookies to improve your experience.",
buttonText: "Allow All",
manageButtonText: "Customize",
// ... override any other translations
}}
>

</CookieManager>i18next Integration
When using i18next, make sure your translation files include all the keys under your chosen prefix:
{
"cookies": {
"title": "Cookie Settings πͺ",
"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>
);
