cookie-consent-js
A simple dialog and framework to handle the German and EU law (as written by EuGH, 1.10.2019 – C-673/17) about cookies
in a website.
cookie-consent-js has no external dependencies, and it works also with Bootstrap.
Note We made another version with more detailed cookie settings, which needs Bootstrap. You find it
at https://github.com/shaack/bootstrap-cookie-consent-settings
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 <head>
or at the bottom of your <body>
.
4. Initialize the Script
var cookieConsent = new CookieConsent({privacyPolicyUrl: "/privacy-policy.html"})
In props
you should at least define 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()) {
}
Server side PHP: Surround your tracking code with
if($_COOKIE['cookie-consent-tracking-allowed'] === 'true') {
}
All other languages: Just read, if the cookie cookie-consent-tracking-allowed
is "true"
...that's all! Contact me, if you have questions.
API
This framework writes a cookie (it's default name is cookie-consent-tracking-allowed
)
with the value "true"
, if the user has accepted tracking. You can read the value with the JavaScript
API (cookieConsent.trackingAllowed()
) or from any other language, server or client side, which can read cookies.
JavaScript API
Show the settings dialog again
cookieConsent.reset()
Use this to allow the user to reconfigure the cookie settings, for example, in your service navigation as "Cookie
settings".
Read the status
cookieConsent.trackingAllowed()
Returns true
if the user did accept tracking cookies. Use this function to disable tracking. Surround tracking code,
like the Google Analytics code with
if (cookieConsent.trackingAllowed()) {
}
Read the status from PHP
Read the cookie from a PHP server with
if($_COOKIE['cookie-consent-tracking-allowed'] === 'true') {
}
