    # CDN links
    https://cdn.jsdelivr.net/gh/orestbida/cookieconsent@v2.9.2/dist/cookieconsent.js
    https://cdn.jsdelivr.net/gh/orestbida/cookieconsent@v2.9.2/dist/cookieconsent.css

    Thanks to Till Sanders for bringing the plugin on npm!

    npm i vanilla-cookieconsent
  2. Import the production version of the plugin (dist folder):

    <html>
        <head>
            <!-- Load stylesheet -->
            <link rel="stylesheet" href="cookieconsent.css">
        </head>
        <body>
            <!-- Load script with the "defer" keyword -->
            <script defer src="cookieconsent.js"></script>
        </body>
    </html>

    If you're on React, check out the FAQ for more details or this live Stackblitz demo.

    If you're using VUE/Nuxt, check out this example setup.

  3. Configure the plugin:

    Since there are no default settings, you must configure the (cookie) categories and at least one language! Example configurations:

    • using an external script

      • Create a .js file (e.g. cookieconsent-init.js) and import it in your html page

        <body>
            <!-- Load script with the "defer" keyword -->
            <script defer src="cookieconsent.js"></script>
            <script defer src="cookieconsent-init.js"></script>
        <body>
      • Configure the plugin inside cookieconsent-init.js

        // obtain plugin
        var cc = initCookieConsent();
        
        // run plugin with your configuration
        cc.run({
            current_lang: 'en',
            autoclear_cookies: true,                   // default: false

                                          }
                                      }, {

                                      }, {

                                  ]
                              }
                          }
                      }
                  });
              });
          </script>
      <body>

  4. Add a button/link to show the settings modal:

    <button type="button" data-cc="c-settings">Manage cookie settings</button>
  5. Now you must configure the scripts and cookies.


How to block/manage scripts

You can manage any script tag (inline or external).

  1. Enable page_scripts option:

    cc.run({
        // ...
        page_scripts: true
        // ...
    });
  2. Set type="text/plain" and data-cookiecategory="<category>" to any script tag you want to manage:

    <!-- External script -->
    <script
        type="text/plain"
        data-cookiecategory="analytics"
        src="analytics.js">
    </script>
    
    <!-- Inline script -->
    <script
        type="text/plain"
        data-cookiecategory="ads">
        console.log('"ads" category accepted');
    </script>

    You can also specify a custom type via the data-type attribute:

    <script
        type="text/plain"
        data-type="module"
        data-cookiecategory="analytics"
        src="test.js">
    </script>

    Note: the type="text/plain" disables the script tag (required attribute)!


How to clear cookies

You can configure the plugin so that it automatically clears existing cookies when a category is rejected/disabled.

Cookies must be listed manually as the plugin is not aware of them.

  1. Enable the autoclear_cookies option:

    cc.run({
        // ...
        autoclear_cookies: true,
        // ...
    });
  2. Add the settings_modal.cookie_table_headers field:

    cc.run({
        // ...
        autoclear_cookies: true,
    
        languages: {
            en: {
                // ...
                settings_modal: {
                    // ...
                    cookie_table_headers: [
                        {col1: 'Name'},
                        {col2: 'Service'},
                        {col3: 'Description'}
                    ]
                }
            }
        }
    });
  3. Add the cookie_table field under the desired category block. A category block must contain the toggle object with a valid category name (toggle.value).

    cc.run({
        // ...
        autoclear_cookies: true,
        // ...
    
        languages: {
            'en': {
                // ...
                settings_modal: {
                    // ...
                    cookie_table_headers: [
                        {col1: 'Name'},
                        {col2: 'Service'},
                        {col3: 'Description'}
                    ],
                    blocks: [
                        // ...
                        {
                            // ...
                            toggle: {
                                value: 'analytics'
                            },
                            cookie_table: [
                                {
                                    col1: '^_ga',
                                    col2: 'Google Analytics',
                                    col3: 'description ...',
                                    is_regex: true
                                },
                                {
                                    col1: '_gid',
                                    col2: 'Google Analytics',
                                    col3: 'description ...',
                                }
                            ]
                        }
                    ]
                }
            }
        }
    });

    For the autoclear function to work, the first column must contain the name of the cookie!

    You can also specify 3 optional fields for each cookie item:

    • is_regex: boolean
    • domain: string
    • path: string

    The is_regex option is handy if you want to match multiple cookies without specifying them individually.

    // Match all cookies starting with `'_ga'`
    {
        col1: '^_ga',
        is_regex: true
    }
    // Match only the `'_ga'` cookie
    {
        col1: '_ga',
    }

    The domain domain option is useful when you are in a subdomain but you want to clear cookies set in the main domain:

    {
        col1: '_ga',
        domain: 'example.com'   // main domain
    }

    Full example.


Layout options & customization

You can choose a few layout options via gui_options.

cc.run({
    // ...
    gui_options: {
        consent_modal: {
            layout: 'cloud',               // box/cloud/bar
            position: 'bottom center',     // bottom/middle/top + left/right/center
            transition: 'slide',           // zoom/slide
            swap_buttons: false            // enable to invert buttons
        },
        settings_modal: {
            layout: 'box',                 // box/bar
            position: 'left',              // left/right
            transition: 'slide'            // zoom/slide
        }
    }
    //...
});

How to customize the color scheme

You can customize the color scheme using css variables, which you can find at the top of cookieconsent.css file.


API

Once you configure and run the plugin:

const cc = initCookieConsent();

cc.run({
    // required config.
});

the following methods are available:

  • cc.show(delay?: number, createModal?: boolean)
  • cc.hide()
  • cc.showSettings(delay?: number)
  • cc.hideSettings()

  • cc.accept(<accepted_categories>, <optional_rejected_categories>) [v2.5.0+]

    • accepted_categories: string or string[]
    • rejected_categories: string[] - optional

    Note: all categories marked as readonly will ALWAYS be enabled/accepted regardless of the categories provided inside the .accept() API call.

    Examples:

    cc.accept('all');                // accept all categories
    cc.accept([]);                   // accept none (reject all)
    cc.accept('analytics');          // accept only analytics category
    cc.accept(['cat_1', 'cat_2']);   // accept only these 2 categories
    cc.accept();                     // accept all currently selected categories inside modal
    
    cc.accept('all', ['analytics']); // accept all except "analytics" category
    cc.accept('all', ['cat_1', 'cat_2']); // accept all except these 2 categories

    How to later reject a specific category (cookieconsent already accepted)? Same as above:

    cc.accept('all', ['targeting']);     // opt out of targeting category

  • cc.allowedCategory(<category_name>)

    Note: there are no default cookie categories, you create them!

    A cookie category corresponds to the string of the value property inside the toggle object:

    // ...
    toggle: {
        value: 'analytics',      // cookie category
        enabled?: false,         // default status
        readonly?: false         // allow to enable/disable
        reload?: 'on_disable',   // allows to reload page when the current cookie category is deselected
    }
    // ...

    Example:

    // Check if user accepts cookie consent with analytics category enabled
    if (cc.allowedCategory('analytics')) {
        // yoo, you might want to load analytics.js ...
    };

  • cc.validCookie(<cookie_name>)

    If cookie exists and has non empty ('') value => return true, otherwise false.

    // Example: check if '_gid' cookie is set
    if (!cc.validCookie('_gid')) {
        // yoo, _gid cookie is not set, do something ...
    };

  • cc.validConsent()

    If consent is valid return true, otherwise false.

    // Example: show modal if consent is not valid
    if (!cc.validConsent()) {
        cc.show();
    }

  • cc.eraseCookies(<cookie_names>, <optional_path>, <optional_domains>) [v2.5.0+]

    • cookie_names: string[]
    • path: string - optional
    • domains: string[] - optional

    Examples:

    cc.eraseCookies(['cc_cookies']);             // erase "cc_cookie" if it exists
    cc.eraseCookies(['cookie1', 'cookie2']);     // erase these 2 cookies
    
    cc.eraseCookies(['cc_cookie'], "/demo");
    cc.eraseCookies(['cc_cookie'], "/demo", [location.hostname]);

  • cc.loadScript(<path>, <callback_function>, <optional_custom_attributes>)

    Basic example:

    cc.loadScript('https://www.google-analytics.com/analytics.js', function(){
        // Script loaded, do something
    });

    How to load scripts with custom attributes:

    cc.loadScript('https://www.google-analytics.com/analytics.js', function(){
        // Script loaded, do something
    }, [
        {name: 'id', value: 'ga_id'},
        {name: 'another-attribute', value: 'value'}
    ]);

  • cc.set(<field>, <object>) [v2.6.0+]

    The .set() method allows you to set the following values:

    • data (used to save custom data inside the plugin's cookie)
    • revision

    How to save custom data:

    // Set cookie's "data" field to whatever the value of the `value` prop. is
    cc.set('data', {value: {id: 21, country: "italy"}});
    
    // Only add/update the specified props.
    cc.set('data', {value: {id: 22, new_prop: 'new prop value'}, mode: 'update'});

  • cc.get(<field>) [v2.6.0+]

    The .get() method allows you to retrieve any of the fields inside the plugin's cookie:

    cc.get('level');     // retrieve all accepted categories (if cookie exists)
    cc.get('data');      // retrieve custom data (if cookie exists)
    cc.get('revision');  // retrieve revision number (if cookie exists)

  • cc.getConfig(<field>) [v2.7.0+]

    The .getConfig() method allows you to read configuration options from the current instance:

    cc.getConfig('current_lang');        // get currently used language
    cc.getConfig('cookie_expiration');   // get configured cookie expiration
    // ...

  • cc.getUserPreferences() [v2.7.0+]

    The .getUserPreferences() returns the following object (for analytics/logging purposes):

    {
        accept_type: string,            // 'all', 'necessary', 'custom'
        accepted_categories: string[],  // e.g. ['necessary', 'analytics']
        rejected_categories: string[]   // e.g. ['ads']
    }

  • cc.updateScripts() [v2.7.0+]

    This method allows the plugin to manage dynamically added/injected scripts that have been loaded after the plugin's execution.

    E.g. dynamic content generated by server side languages like php, node, ruby ...

  • cc.updateLanguage(<language>, <force_update>) [v2.8.0+]

    Use this method to change modal's language dynamically (without page reload).

    • language: string
    • force_update: boolean - optional

    Example:

    cc.updateLanguage('it');

    Note: language will change only if it is valid (already defined) and different from the current language!


    You can also forcefully update the modals (useful if you dynamically change the content of the modals). Example:

    // Change content: e.g. modify modal title
    cc.getConfig('languages').en.consent_modal.title = 'New title';
    
    // Update changes
    cc.updateLanguage('en', true);


Available callbacks

  • onAccept

    This function will be executed:

    • at the first moment that consent is given (just like onFirstAction)
    • after every page load, if consent (accept or "reject" action) has already been given

    parameters:

    • cookie: contains the current value of the cookie

    example:

    //...
    cc.run({
        // ...
        onAccept: function(cookie){
            // load script, e.g. google analytics ...
        },
        // ...
    });

  • onChange

    This function will be executed (only if consent has already been given):

    • when user changes his preferences (accepts/rejects a cookie category)

    parameters:

    • cookie: contains the current value of the cookie
    • changed_categories: array of categories whose state (accepted/rejected) just changed

    example:

    //...
    cc.run({
        // ...
        onChange: function(cookie, changed_categories){
            // cleanup logic ... (e.g. disable gtm if analytics category is disabled)
        },
        // ...
    });

  • onFirstAction [v2.7.0+]

    This function will be executed only once, when the user takes the first action (accept/reject).

    parameters:

    • user_preferences: contains the same data provided by the .getUserPreferences() API
    • cookie: contains the current value of the cookie

    example:

    //...
    cc.run({
        // ...
        onFirstAction: function(user_preferences, cookie){
            console.log('User accept type:', user_preferences.accept_type);
            console.log('User accepted these categories', user_preferences.accepted_categories)
            console.log('User reject these categories:', user_preferences.rejected_categories);
        },
        // ...
    });


Custom data-cc attribute

You can add the data-cc attribute to any element (typically a button) to perform a few actions without having to use code.

Valid values:

  • c-settings: show settings modal
  • accept-all: accept all categories
  • accept-necessary: accept only categories marked as necessary/readonly (reject all)
  • accept-custom: accept currently selected categories inside the settings modal

Example:

<button type="button" data-cc="c-settings">Show cookie settings</button>

Configuration options

Below a table which sums up all of the available options (must be passed to the .run() method).

How to manage revisions

Revisions can be enabled by setting a value different from 0 (default). If the saved revision number (stored in the cookie) is different from the current one, the consent modal will be shown.

  1. Enable revisions by setting a revision number > 0:

    cc.run({
        // ...,
        revision: 1,
        // ...
    })
  2. You can optionally set a revision message. To do this, add the revision_message parameter inside consent_modal, and also place the following placeholder {{revision_message}} inside the description field:

    cc.run({
        // ...,
        revision: 1,
        // ...,
        languages: {
            en: {
                consent_modal: {
                    // ...,
                    description: 'Usual description ... {{revision_message}}',
                    revision_message: '<br> Dude, my terms have changed. Sorry for bothering you again!',
                    // ...
                },
                // ...
            }
        }
        // ...
    })

If your main domain and subdomain share the same cookieconsent configuration, you can also share the consent by pointing all configurations to the same cookie (using the main domain).

In the plugin's config. simply specify the main domain in the cookie_domain option:

var cc = initCookieConsent();

cc.run({
    // ...
    cookie_domain: 'domain.com'
});

E.g. if your main domain is "loremipsum.com" or "www.loremipsum.com", you have to put "loremipsum.com".


How to block iframes

CookieConsent does not have any built-in functionality to block iframes. You can however use iframemanager which was specifically designed for this task.


FAQ

  • How to enable dark mode

    Either manually add the following class c_darkmode to the body/html tag, or toggle it via javascript:

    document.body.classList.toggle('c_darkmode');

  • How to add link/button to open cookie settings

    Create a button (or link) with data-cc="c-settings" attribute:

    <button type="button" data-cc="c-settings">Cookie Settings</button>

  • How to integrate with a multi-language website

    If you have multiple versions of your html page, each with a different <html lang="..." > attribute, you can grab this value using:

    document.documentElement.getAttribute('lang');

    and then set it as current_lang value like this:

    cc.run({
        // ...
        current_lang: document.documentElement.getAttribute('lang'),
        // ...
    });

    Note: make sure that the lang attribute's value format (example: 'en' => 2 characters) is identical to the ones you defined. If you have 'en-US' as lang attribute, make sure to also specify 'en-US' (and not just 'en') in the config. parameters.

  • How to load scripts after a specific cookie category has been accepted

    Suppose you have a analytics.js file you want to load after the analytics category has been accepted:

    • Method 1 (recommended)

      1. enable page_scripts:

        cc.run({
            // ...
            page_scripts: true,
            // ...
        });
      2. add a <script> tag with the following attributes: type="text/plain" and data-cookiecategory="<category>"

        <script type="text/plain" data-cookiecategory="analytics" src="<path-to-analytics.js>"></script>

    • Method 2

      Load script using the .loadScript() method inside the onAccept method:

      cc.run({
          // ...
          onAccept: function () {
              if (cc.allowedCategory('analytics')) {
                  cc.loadScript('analytics.js', function () {
                      // script loaded ...
                  });
              }
          }
      })

  • Make consent required (block page navigation until action)

    This is a css only solution:

    1. enable force_consent option:
      cc.run({
          // ...
          force_consent: true,
          // ...
      });
    2. That should do it. If you want to remove the weird horizontal jump (due to the scrollbar disappearing) you can add the following style inside the head tag of your page:
      <style>
          html,
          body {
              height: auto!important;
              width: 100vw!important;
              overflow-x: hidden!important;
          }
      </style>

  • How to create custom cookie tables

    • Cookie tables are defined by you, that is you choose how many columns and what their naming will be
    • Make sure that the first column of the table contains the name of the cookie for autoclear_cookie to work properly

    1. Specify the table structure via the cookie_table_headers property inside settings_modal object:

      Example with 3 columns:

      // ...
      cookie_table_headers: [
          {col1: "Name"},
          {col2: "Source"},
          {col3: "Description"},
      ]
      // ...
    2. Now you can create a cookie_table array of objects:

      // ...
      cookie_table: [
          {
              col1: '_ga',
              col2: 'google.com',
              col3: 'description ..',
          },
          {
              col1: '_gid',
              col2: 'google.com',
              col3: 'description ..',
          }
      ]
      // ...

    Check the examples above for a valid implementation.

  • How to use in React

    You can find a live demo ( next.js) on stackblitz.

    1. Create a new component: CookieConsent.js

      import { useEffect } from "react";
      
      import 'vanilla-cookieconsent';
      import 'vanilla-cookieconsent/dist/cookieconsent.css';
      
      export default function CookieConsent() {
          useEffect(() => {
      
              if (!document.getElementById('cc--main')) {
                  window.CC = window.initCookieConsent();
                  window.CC.run({
                      // your config (required)
                  });
              }
      
          }, []);
      
          return null;
      }
    2. Import the component in your main/root file (e.g. App.js):

      import CookieConsent from "./<path-to-CookieConsent.js-component>";
      
      export default function App() {
          return (
              <div className="App">
                  <h1>Hello World</h1>
      
                  <CookieConsent/>
              </div>
          );
      }
