Sometimes it's not possible to avoid cookies for which we need consent of the visitors of our web applications. For that, some kind of component might help which provides a sleek, but customizable UI with an easy to use API.
That's where the Cookie Consent Banner comes in.
In order to focus on the things that really matter, the Cookie Consent Banner supports us to fulfill that requirement.
It visualizes the available categories, like technically required and analysis, stores the decision of the user and provides an event-based API for you to handle appropriately. And of course, the consent data is stored locally in the vistor's browser.
:arrows_counterclockwise: Consent Flow
The consent banner has two tasks: Providing a UI Component to allow visitors of your web application to choose which cookies they want to accept, and the ability to react on the choosen settings via an API.
There are two typical scenarios: Either the external scripts, which set cookies are managed through a tag manager of your choice using the consent data, or the scripts are loaded or configured directly on code level.
Using a Tag Manager
The flow could look like this: Every script that sets cookies which require a consent from the visitor is blocked by default.
Instead, the Consent Banner is shown. Once the visitor updates its preferences an event is triggered (cookie_consent_preferences_updated).
Additionally the consent data is stored within a cookie in a format that can be parsed either programmatically or with a tag manager (e.g.: name: cookies_accepted_categories, value: technically_required,analytics,marketing). A tag manager could read the value of that 1st-Party Cookie before any other script (tag) is loaded (e.g.: Fire trigger only if Accepted Cookie Categories contains marketing).
Using the API directly

:spiral_notepad: Documentation
The Cookie Consent Banner supports multiple frontend frameworks, because it is built as an agnostic web component. For easier integration we also provide a wrapper component for React environments. It's necessary to set at least the required properties for the component in order to work properly (see the provided examples).
