Customizable GDPR Cookie Consent Popup In JavaScript – Cookify


Cookify is a highly customizable GDPR cookie consent popup library to make your site or app compliant with GDPR and EU Cookie Law.

The GDPR cookie consent popup enables visitors to manage (enable and disable) cookies allowed to use, and toggle scripts on/off accordingly.


$ npm i cookify

How to use it:

1. The library requires Bootstrap’s stylesheet loaded in the document.

<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />

2. Import the Cookify as an ES module.

import Cookify from './src/index.js';

3. Initialize the Cookify library and pass the following parameters:

var cookify = new Cookify(
    dataName = 'cookify', 
    actionCallback = () => {}, 
    trackingCallback = () => {}, 
    saveWithChange = false, 
    saveByDefault = false, 
    cookieDefault = 'necessary',

4. Create checkboxes to manage your cookies:

<div class="m-3 fixed-bottom">
  <div id="manage" class="mx-md-5 p-3 bg-white shadow-lg rounded d-none" data-c-view="manage">
    <h2>Manage Cookies</h2>

        <input data-c-check="necessary" class="form-check-input" type="checkbox" value="" id="necessary">
        <label class="form-check-label" for="necessary">
      <div class="form-check">

      <div class="form-check">
        <input data-c-check="performance" class="form-check-input" type="checkbox" value="" id="performance">
        <label class="form-check-label" for="performance">
    <div class="d-flex">
      <div data-c-action="accept" class="btn btn-secondary flex-fill me-1">
      <div data-c-action="all" class="btn btn-primary flex-fill">
      <div data-c-action="necessary" class="btn btn-primary flex-fill ms-1">

5. Toggle on/off scripts based on user selection.

<script src="app.js" data-c-script="necessary"><script>
<script src="analytics.js" data-c-script="marketing"><script>
