## Quick Start

Get up and running quickly with React Cookie Manager:

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

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

createRoot(document.getElementById("root")).render(
  <StrictMode>
    <CookieManager>
      <App />

    <CookieManager
      cookieKitId="" // Get this from cookiekit.io
      translations={{
        title: "Cookie Preferences",

## 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

```bash
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`):

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

![React Cookie Manager Styles](https://github.com/hypershiphq/react-cookie-manager/blob/main/assets/banner-styles.jpg?raw=true)

## Basic Usage

```jsx
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:

```tsx
"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

```jsx
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

```jsx
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

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

### Features

- 🎯 Automatically appears after initial consent
- 🎨 Matches your theme (light/dark mode)
- 🔄 Smooth animations and hover effects
- ❌ Dismissible with a close button
- 📱 Responsive and mobile-friendly
- 🎛️ Easy access to cookie preferences

### Behavior

1. The button appears after users make their initial cookie choice
2. Hovering reveals a close button to dismiss the floating button
3. Clicking opens the cookie preferences modal
4. The button remains hidden until page refresh after being closed
5. Maintains position during scroll

### Customization

The floating button automatically adapts to your chosen theme:

```jsx
// Light theme (default)
<CookieManager
  enableFloatingButton={true}
  theme="light"
>
  <YourApp />
</CookieManager>

// Dark theme
<CookieManager
  enableFloatingButton={true}
  theme="dark"
>
  <YourApp />
</CookieManager>
```

The button inherits your color scheme:

- Light theme: White background with gray text
- Dark theme: Black background with light gray text

### Accessibility

The floating button is fully accessible:

- Proper ARIA labels
- Keyboard navigation support
- Focus management
- High contrast ratios
- Screen reader friendly

## CSS Customization

React Cookie Manager provides extensive styling customization through the `classNames` prop. You can override the default styling for each element of the cookie consent UI.

  Analytics: boolean;
  Social: boolean;
  Advertising: boolean;
}
```

## Hook API

The `useCookieConsent` hook provides the following:

```typescript
interface CookieConsentHook {
  hasConsent: boolean | null;
  isDeclined: boolean;
  detailedConsent: DetailedCookieConsent | null;
  showConsentBanner: () => 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` |

### Usage Example

```jsx
<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

```typescript
import { default as i18next } from "i18next";

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

```json
// 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:

```typescript
{
  // 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
  manageSocialTitle: "Social",
  manageSocialSubtitle: "Enable social media features and sharing",

  // Advertising cookies section
  manageAdvertTitle: "Advertising",
  manageAdvertSubtitle: "Personalize advertisements and measure their performance",

  // Status messages
  manageCookiesStatus: "Status: {{status}} on {{date}}", // Supports variables
  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:

```jsx
<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:

```json
{

Then use it with the i18next translation function:

```jsx
import { useTranslation } from "react-i18next";

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

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