Fever Cookies
A simple, lightweight cookie consent system.
Features
- Only loads cookies after the user gives consent
- Allows user preferences to be changed at any time via settings
- Splits cookies into categories
Getting Started
CDN
To start using Fever Cookies right away, you can use the CDN to serve the files as close, and fast as possible to users.
Simply add the CSS & JS in your <head>:
<link rel="stylesheet" type="text/css" media="screen" href="//cdn.jsdelivr.net/npm/@thisisfever/cookies@1/dist/fever-cookies.min.css" />
<script src="//cdn.jsdelivr.net/npm/@thisisfever/cookies@1/dist/fever-cookies.min.js" defer></script>NPM Package
Note: If you intend to use Fever Cookies with the CDN, you can skip this
- Install package via the following command:
$ npm install @thisisfever/cookies
- Import core script to your JS using:
import '@thisisfever/cookies/src/fever-cookies';
- Import core styling to your SCSS using:
import "~@thisisfever/cookies/src/fever-cookies";
Usage
First you need to initilise Fever Cookies.
-
Add the following in your
<head>, below the CSS & JS:<script> window.addEventListener('load', function() { window.FeverCookies({ settings_toggle: '.cookie-settings-btn', policy: { link: '/cookies-policy/', name: 'Cookies Policy', }, optional_cookies: { analytics: { cookies: [], onAccept: function() { }, onRevoke: function() { } }, marketing: { cookies: [], onAccept: function() { }, onRevoke: function() { } } } }); }); </script>
-
To start adding scripts, you can integrate in two ways, or a combination of both:
- Modify each script tag
- Add JS directly into Fever Cookies
Modify Scripts
To prevent a script from loading (unless the relevent category has been chosen by the user), you need to modify the script.
We need to add
data-cookie="[category]andtype="text/plain"to the script tag.For example, Google Analytics would look like this:
<script type="text/plain" data-cookie="analytics" async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXXXX-X"></script>
Important: For each category, you must fill in the the
cookies: []array with the names of the cookies used within that category.Add JS to Fever Cookies
When you initialse the package, there is a
optional_cookiesobject.optional_cookies: { analytics: { cookies: [], onAccept: function() { }, onRevoke: function() { } }, marketing: { cookies: [], onAccept: function() { }, onRevoke: function() { } } }
For each category, you must fill in the the
cookies: []array with the names of the cookies used within that category.For example, Google Analytics would be:
cookies: ['_ga', '_gid', '_gat', '_gat_gtag_UA_XXXXXXXX_X'],
For any JS you wish to run when a category is accepted, add it directly to the category's
onAccept.onAccept: function() { // This category has been accepted, run JS here },
Likewise, you can add any JS you wish to run when a category has been revoked using
onRevokeonRevoke: function() { // This category has been revoked, run JS here },
