A modern, GDPR-compliant cookie consent banner for Rails applications

Easily integrate a customizable, fully-featured cookie consent banner in your Ruby on Rails application. Built with modern web standards, responsive design, and complete GDPR compliance in mind.

• 🎨 Modern responsive design - Clean, accessible UI that works on all devices
• 🍪 Smart cookie management - Automatically remove specific cookies when consent is refused
• ⚙️ Highly customizable - Customize text, links, duration, and appearance
• 🚀 Zero dependencies - Pure JavaScript, no external libraries required
• 📱 Mobile optimized - Touch-friendly interface with responsive breakpoints

Add to your Gemfile:

gem "immosquare-cookies"

Run:

bundle install

Add to your layout or view:

<%= render("immosquare-cookies/consent_banner") %>

For modern Rails applications using cssbundling-rails or similar:

1. Add the following to your package.json scripts:

{
  "scripts": {
    "build:css": "ruby scripts/compile_sass.rb",
    "build:css-dev": "ruby scripts/compile_sass.rb development"
  }
}

2. Create scripts/compile_sass.rb:

#!/usr/bin/env ruby

require_relative "../config/environment"

cmd = "sass ./app/assets/stylesheets/application.sass.scss ./app/assets/builds/application.css #{Rails.application.config.assets.paths.map {|path| "--load-path=#{path}" }.join(" ")}"
cmd += ARGV[0] == "development" ? " --source-map --source-map-urls=absolute --watch" : " --style compressed"

system(cmd)

3. Update your Procfile.dev:

web: bin/rails server -p 3000
css: bun run build:css-dev
js: bun run build-dev --watch

<%= render("immosquare-cookies/consent_banner") %>

<%= render("immosquare-cookies/consent_banner",
    privacy_policy_link: "https://example.com/privacy",
    cookie_policy_link: "https://example.com/cookies") %>

<%= render("immosquare-cookies/consent_banner",
    site_name: "MyApp",
    duration_months: 12,
    privacy_policy_link: "https://example.com/privacy",
    cookie_policy_link: "https://example.com/cookies",
    cookies_to_remove: ["_ga", "_gid", "_fbp", "_gat"],
    target: "_blank") %>

New in v2.0! The cookies_to_remove parameter automatically removes unwanted cookies when users refuse consent.

<%= render("immosquare-cookies/consent_banner",
    cookies_to_remove: ["_ga", "_gid", "_fbp", "_gat_UA-*"]) %>

This prevents tracking cookies from being recreated and ensures true GDPR compliance.

Check consent before loading tracking scripts:

<% if cookies["_immosquare_consented"] != "false" %>
  <!-- Google Analytics -->
  <script async src="https://www.googletagmanager.com/gtag/js?id=GA_MEASUREMENT_ID"></script>
  <script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'GA_MEASUREMENT_ID');
  </script>
<% end %>

Built-in translations for 7 languages:

• 🇫🇷 French (fr)
• 🇬🇧 English (en)
• 🇪🇸 Spanish (es)
• 🇳🇱 Dutch (nl)
• 🇮🇹 Italian (it)
• 🇨🇳 Simplified Chinese (zh)
• 🇹🇼 Traditional Chinese (zh-TW)

Customize translations in your app's locale files:

en:
  immosquare-cookies:
    document_title: "Cookie Settings for %{site_name}"
    text: "We use cookies to enhance your experience. By continuing to visit this site, you agree to our use of cookies for %{duration_months} months."
    refuse: "Refuse"
    accept: "Accept"
    link_text: "Learn more:"
    privacy_policy: "Privacy Policy"
    cookie_policy: "Cookie Policy"

The banner features a modern, accessible design with:

• Clean card-based layout with subtle shadows
• Responsive breakpoints for mobile and desktop
• CSS custom properties for easy theming
• Smooth animations and hover effects
• Fixed bottom-left positioning (non-intrusive)

Override CSS custom properties:

#immosquare-cookies-container {
  --immosquare-cookies-color: #your-brand-color;
  --immosquare-cookies-bg: #your-background;
  --immosquare-cookies-border: #your-border-color;

}

immosquare-cookies v2.0 includes breaking changes and major improvements.
