Default cookie banner

Default cookie Modal

Usage / Examples ✏️

You can either use the components right out of the box without setting any properties or completely customize either one of the consent components in your own taste.

Cookie modal 💚

Basic

import { CookieBanner } from '@schlomoh/react-cookieConsent'

const MyApp = () => (
    <>
        <CookieBanner > // above the rest of the page
        <MyPage />
    </>
)

Cookie banner 💙

Basic

import { CookieModal } from '@schlomoh/react-cookieConsent'

const MyApp = () => (
    <>
        <CookieModal > // above the rest of the page
        <MyPage />
    </>
)

Customized 📐

(All properties work for both modal and banner)

...

const Content = () => (
    <>
        <h3>I'm using cookies on my site.</h3>
        <p>Bla Bla Bla this is my own informational text.</p>
    </>
)

const containerStyle = {backgroundColor: '#333'};
const buttonStyle = {borderRadius: 0}
const primaryButtonStyle={...buttonStyle, backgroundColoe:'red'}
const secondaryButtonStyle={...buttonStyle, backgroundColoe:'blue'}

const MyApp = () => (
    <>
        <CookieBanner 
            acceptButtonText='I want it'
            declineButtonText='Go away'
            headingColor='white'
            paragraphColor='grey'
            containerStyle={containerStyle}
            primaryButtonStyle={primaryButtonStyle}
            secondaryButtonStyle={secondaryButtonStyle}
            infoContent={<Content />}
        />
        <MyPage />
    </>
)

... it then looks like this (dont mind the text👀 earlier screenshot):

Enabling cookie preferences 🔧

To let a visitor select their cookie preferences the property enableManagement has to be set to true.

You can then set an array of cookie categories which the user can select from. There is always the category "Necessary" predefined and set to true and disabled by default.

When enableManagement is set you can also override the default text of the button by setting managementButtonText='whatever'. This button is a secondary button.

For example

<>
    <CookieBanner
        enableManagement
        managementButtonText='manage cookie preferences'
        cookieCategories={['analytics', 'advertisement']}
    />
</>

Callbacks 👉🏼

You can define callbacks which are called on either accept or decline. Simply pass a function into the onAccept or onDecline property which is executed accordingly.

The onAccept event can pass an object with the selected cookies as ICookieObject into your accept callback.

const onAccept = (cookies : ICookieObject) => {
    console.log(cookies);
};

const onDecline = () => {
    console.log('declined');
}


// inside your app
const MyApp = () => (
    <>
        <CookieBanner
        onAccept={onAccept} 
        onDecline={onDecline}
        />
    <>
)

Reference 🔎

The ICookieObject:

interface ICookieObject {
  [key: string]: boolean;
}

Example:

{ "advertisement": false, "analytics": true }

<table> <tr> <th>Prop</th> <th>Type</th> <th>Default</th> <th>Description</th> </tr> <tr> <td>onAccept</td> <td>function(cookies?: ICookieObject){}</td> <td>()=>{}</td> <td>Function called when user clicks "accept"</td> </tr> <tr> <td>onDecline</td> <td>function(){}</td> <td>()=>{}</td> <td>Function called when user clicks "decline"</td> </tr> <tr> <td>infoContent</td> <td>JSX.Element</td> <td>-</td> <td>A JSX component that should contain the heading and paragraph of the greeting view</td> </tr> <tr> <td>managementContent</td> <td>JSX.Element</td> <td>-</td> <td>A JSX component rendered in the management view above the cookie checkboxes best containing heading and paragraph text.</td> </tr> <tr> <td>acceptButtonText</td> <td>string</td> <td>"Accept"</td> <td>String displayed in the accept button</td> </tr> <tr> <td>declineButtonText</td> <td>string</td> <td>"Decline"</td> <td>String displayed in the decline button</td> </tr> <tr> <td>managementButtonText</td> <td>string</td> <td>"Manage Cookies"</td> <td>String displayed in the management toggle button</td> </tr> <tr> <td>enableManagement</td> <td>boolean</td> <td>false</td> <td>Set to true to display the third button which toggles the management view (where visitors select their cookie preferences). </td> </tr> <tr> <td>cookieCategories</td> <td>string[] (array of strings)</td> <td>[]</td> <td>An array listing the available cookie preferences to choose from.</td> </tr> <tr> <td>accentColor</td> <td>string (React.CSSProperties.backgroundColor)</td> <td>'coral'</td> <td>The accent color used for the primary butttons</td> </tr> <tr> <td>headingColor</td> <td>string (React.CSSProperties.color)</td> <td>'black'</td> <td>The color applied to h1, h2, h3, h4 elements inside the views</td> </tr> <tr> <td>paragraphColor</td> <td>string (React.CSSProperties.color)</td> <td>'grey'</td> <td>The color applied to p elements inside the views</td> </tr> <tr> <td>containerStyle</td> <td>object (React.CSSProperties)</td> <td>-</td> <td>Style object overriding the banner or modal style</td> </tr> <tr> <td>primaryButtonStyle</td> <td>object (React.CSSProperties)</td> <td>-</td> <td>Style object overriding the primary buttons' style</td> </tr> <tr> <td>secondaryButtonStyle</td> <td>object (React.CSSProperties)</td> <td>-</td> <td>Style object overriding the secondary buttons' style</td> </tr> </table>

Sample usage in a NextJs project

1. Make a component named Cookie.tsx in your components folder with the following content.

'use client';

import { CookieBanner } from '@schlomoh/react-cookieconsent';
import React from 'react';

const MyCookieBanner = () => {
    const Content = () => (
        <>
            <h3>Lorem Ipsum Dolor Sit Amet</h3>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. <a href="/cookie" className='text-blue underline'>Cookie Policy</a></p>

        </>
    )

    const MContent = () => (
        <>
            <h3> Lorem Ipsum Dolor Sit Amet </h3>
            <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
        </>
    )
    
    const containerStyle = {backgroundColor: 'white'};
    const buttonStyle = {borderRadius: 0}
    const primaryButtonStyle={...buttonStyle, backgroundColor:'green'}
    const secondaryButtonStyle={...buttonStyle, backgroundColor:'red'}
    
  return (
    <CookieBanner
        acceptButtonText='I accept'
        declineButtonText='Reject'
        headingColor='black'
        paragraphColor='grey'
        containerStyle={containerStyle}
        primaryButtonStyle={primaryButtonStyle}
        secondaryButtonStyle={secondaryButtonStyle}
        infoContent={<Content />}
        enableManagement
        managementContent={<MContent />}
        managementButtonText='Consent Preferences'
        cookieCategories={['analytics', 'advertisement']}
        // accentColor = 'coral'
    />
  );
};

export default MyCookieBanner;
 

2. add the component it your App.js or _app,js or app/layout.js file

import CookieBanner from '@/components/Cookie'
...

...
     
        <ThemeProviders>
          <Analytics analyticsConfig={siteMetadata.analytics as AnalyticsConfig} />
          <SectionContainer>
            <div className="flex h-screen flex-col justify-between font-sans">
              <SearchProvider>
                <Header />               
                <main className="mb-auto">{children}</main>
              </SearchProvider>
              <Footer />
              <CookieBanner />
            </div>
          </SectionContainer>
        </ThemeProviders>
...
