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

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
