GDPR Compliant Overlay

Library that prevents an iframe from being loaded until the user has explicitly accepted the loading. A typical use case my be the usage of Google Maps.
To provide a maximum of flexibility you are responsible for the design and content of the alternate overlay.

Install

npm --save gdpr-c-v

Configuration

1. Define a const config:GDPRCoOvConfig

   GDPRCoOvConfig:
     Properties:
       - wrapperElemId: ID of the HTML element that contains the overlay
       - overlayElemId: ID of the HTML element that represents the overlay
       - cookieValidInDays: number of days the cookie should be saved
       - iframeSettings: IframeSettings Object
   
   IframeSettings:
     Properties:
       - width: width of iframe
       - height: height of iframe
       - frameBorder: border size of iframe in px
       - src: source of iframe
   

2. Create an const instance = new GDPRCoOv(config)

3. After DOM is loaded run instance.init()

4. When user accepts and the iframe should be loaded call instance.userAccepted(cookieEnabled) where cookieEnabled tells the lib whether to save a cookie for the next cookieValidInDays days

How to use - example

Note: for the sake of simplicity the following example is based on react using typescript.

import { GDPRCoOv, GDPRCoOvConfig, IframeSettings } from "gdpr-c-o"

const ExampleFunctionalComponent = (iframeSrc): JSX.Element => {
    const [gdprIframeInstance, setGdprIframeInstance] = React.useState<GDPRCoOv>();
    const [enableCookie, setEnableCookie] = React.useState(false);

    const overlayId = 'overlayId'
    const wrapperId = 'wrapperId'



    React.useEffect(() => {
      const iframSettings = new IframeSettings(
        "100%",
        "350",
        "0",
        iframeSrc
      );

      // gdpr-c-o config
      const gdprConfig = new GDPRCoOvConfig(
        wrapperId,
        overlayId,
        30,
        iframSettings
      );

      const gdprCoOv = new GDPRCoOv(gdprConfig);
      gdprCoOv.init();
      setGdprIframeInstance(gdprCoOv);
    }, [iframeSrc])


    // Overlay
    const Overlay = <div id={overlayId}> </div>

    const checkboxHandler = (event) => {
      setEnableCookie(event.target.checked);
    }

    // hide overlay, show iframe and remember user setting for the future as a cookie
    const userAccepted = () => gdprIframeInstance.userAccepted(enableCookie)

    return (
        <div id={wrapperId}>
            <div id={overlayId}>
              <p>Custom message for the user</p>
              <button type="button" onClick={userAccepted}>Load content anyway</button>
              <input
                      type="checkbox"
                      onChange={checkboxHandler}
                    />
              Remember my setting.
            </div>
        </div>
    )
}
