Usage

Quick Start: CDN

The simplest way to get started is to add it to your page:

<script
  type="text/javascript"
  src="https://cdn.jsdelivr.net/npm/ez-consent@^1/dist/ez-consent.min.js"
  defer
  async
  onload="
        ez_consent.init({
            privacy_url: '/privacy',
            texts: {
                buttons: {
                    ok: 'OK',
                    more: 'More',
                },
            },
        });
    "
></script>

See Initialize the script for additional options and alternative ways.

Advanced Usage

1. Import
2. Initialize
3. Style (optional)

1. Import

Here are some examples how you can install the script:

• Using NPM: npm install ez-consent --save
• Or using yarn: yarn add ez-consent
• Using git submodule (not recommended):
  • Go to the folder you wish to have the repository
  • Run git submodule add https://github.com/undergroundwires/safe-email

Add it to your page:

<script
  type="text/javascript"
  src="/node_modules/ez-consent/dist/ez-consent.min.js"
></script>

Or you can import ez_consent as a module:

<script type="module" async defer>
  import { ez_consent } from './ez-consent/src/ez-consent.js'; // /node_modules/ez-consent/ez-consent.js ...
  ez_consent.init();
</script>

Or import it via webpack, gulp, rollup etc.:

import { ez_consent } from './node_modules/ez-consent/src/ez-consent';

2. Initialize

When importing a script using the <script> element, it's recommended to use the onload attribute to initialize it. This approach allows you to keep both async and defer attributes, which improve webpage performance and user experience by optimizing script loading. This can help your pages rank better in search engines.

<script
  type="text/javascript"
  src="/node_modules/ez-consent/dist/ez-consent.min.js"
  async
  defer
  onload="
        ez_consent.init({
            privacy_url: '/privacy',
            texts: {
                buttons: {
                    ok: 'OK',
                    more: 'More',
                },
            },
        });
    "
></script>

Or, you can initialize later using this snippet:

ez_consent.init();

See all options:

ez_consent.init({
  is_always_visible: false, // Always shows banner on load, default: false
  privacy_url: '/privacy', // URL that "more" button goes to, default: "/privacy/"
  consent_duration: 'P10Y', // Consent duration (cookie expiry date), default: 10 years. ISO 8601 format, decimals are not supported.
  enable_google_consent_mode: false, // Sends consent state to Google (enables Google consent mode)
  more_button: {
    target_attribute: '_blank', // Determines what the behavior of the 'more' button is, default: "_blank", opens the privacy page in a new tab
    is_consenting: true, // Controls whether clicking the 'more' button automatically gives consent and removes the banner, default: true
  },
  texts: {
    main: 'We use cookies', // The text that's shown on the banner, default: "This website uses cookies & similar."
    buttons: {
      ok: 'ok', // OK button to hide the text, default: "ok"
      more: 'more', // More/accept button that shows the privacy policy, default "more"
    },
  },
  css_classes: {
    // CSS class name overrides
    container: 'container', // Main container element, default: "cookie-consent"
    message_text: 'mainText', // Main message text container, default: "cookie-consent__text"
    buttons: {
      wrapper: 'buttonsWrapper', // Button container, default: "cookie-consent__buttons"
      more: 'moreButton', // More info button, default: "cookie-consent__button cookie-consent__button--more"
      ok: 'okButton', // More/accept button, default: "cookie-consent__button cookie-consent__button--ok"
    },
  },
});

The banner will be shown if the user has not yet agreed to read & understand the information. You can force the banner to always show by including the force-consent query parameter in the URL. Example for https://test.com/fest page: test.com/fest?force-consent.
