Demo pages with usage examples

Usage

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.

API

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

cookieConsent.reset()

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

Read the status

cookieConsent.trackingAllowed()

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"
})

Styling

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