    Follow these easy steps to integrate the cookie settings in your page.

    1. Install cookie-consent-js in your project with npm install cookie-consent-js

    Alternatively you can download the git repository.

    2. Include cookie-consent.css

    <link rel="stylesheet" href="/node_modules/cookie-consent-js/src/cookie-consent.css"/>

    This should be done before any bootstrap or other frameworks css. You can overwrite styling in your projects css, take a look at cookie-consent.scss.

    3. Include cookie-consent.js

    <script src="/node_modules/cookie-consent-js/src/cookie-consent.js"></script>

    In your websites <head> or at the bottom of the <body>.

    4. Initialize the Script

    const cookieConsent = new CookieConsent({
        contentUrl: "/node_modules/cookie-consent-js/cookie-consent-content", // location of the language files
        privacyPolicyUrl: "/privacy-policy.html"

    In props you should at least define contentUrl and privacyPolicyUrl. See below "Configuration properties".

    5. Enable "Cookie settings" in your service navigation

    <a href="javascript:cookieConsent.reset()">Cookie settings</a>

    So the user can anytime reconfigure, if he wants tracking or not.

    6. Enable or disable tracking depending on configuration

    Client side JavaScript: Surround your tracking code with

    if (cookieConsent.trackingAllowed()) {
        // Google Analytics code and/or other tracking code

    Server side PHP: Surround your tracking code with

    if($_COOKIE['cookie-consent-tracking-allowed'] === 'true') {
        // do some tracking

    All other languages: Just read, if the cookie cookie-consent-tracking-allowed is "true"

    ...that's all! Contact me, if you have questions.


    This framework writes a cookie (it's default name is cookie-consent-tracking-allowed) with the value "true", if the user has accepted tracking. You can read the value with the JavaScript API (cookieConsent.trackingAllowed()) or from any other language, server or client side, which can read cookies.

    JavaScript API

    Show the settings dialog again


    Use this to allow the user to reconfigure the cookie settings, for example, in your service navigation as "Cookie settings".

    Read the status


    Returns true if the user did accept tracking cookies. Use this function to disable tracking. Surround tracking code, like the Google Analytics code with

    if (cookieConsent.trackingAllowed()) {
        // Google Analytics code and/or other tracking code

    Read the status from PHP

    Read the cookie from a PHP server with

    if($_COOKIE['cookie-consent-tracking-allowed'] === 'true') {
        // do some tracking

    Configuration properties

    With default values.

    self.props = {
        buttonPrimaryClass: "btn btn-primary", // the "accept all" buttons class, only used for styling
        buttonSecondaryClass: "btn btn-secondary", // the "accept necessary" buttons class, only used for styling
        autoShowModal: true, // disable autoShowModal on the privacy policy page, to make that page readable
        blockAccess: false, // set "true" to block the access to the website before choosing a cookie configuration
        position: "right", // position ("left" or "right"), if blockAccess is false
        postSelectionCallback: undefined, // callback, after the user has made a selection
        lang: navigator.language, // the language, in which the dialog is shown
        defaultLang: "en", // default language, if the `lang` is not available as translation in `cookie-consent-content`
        content: [], // deprecated, we now have a `content` folder, which contains the language files
        contentUrl: "./cookie-consent-content", // the url of the "cookie-consent-content" folder, which contains the language files
        privacyPolicyUrl: "privacy-policy.html",
        cookieName: "cookie-consent-tracking-allowed",  // the name of the cookie, the cookie is `true` if tracking was accepted
        modalId: "cookieConsentModal" // the id of the modal dialog element

    Disable autoShow

    You can disable autoShowModal, for instance, in the privacy policy and legal notice pages to make these pages better readable.

    var cookieConsent = new CookieConsent({
        autoShowModal: false,
        privacyPolicyUrl: "privacy-policy.html",
        contentUrl: "./cookie-consent-content"


    See ./src/cookie-consent.scss and overwrite values as you need in your project's stylesheet.
