📦 Installation

Install the package using the following npm command:

npm install add-to-calendar-button-react

It requires React and React-Dom, both >=18.0.0. The installer will warn you automatically if your setup does not fit.

🎛️ Setup & Configuration

Import the component wherever you want to use it:

import { AddToCalendarButton } from 'add-to-calendar-button-react';

Use the componet inside your code and declare any options as props. You will get warned about any type misconfiguration.

Calendar type options and time zone information are not required, but recommended.


If you need to use the type explicitely, you can import it via:

import type { AddToCalendarButtonType } from 'add-to-calendar-button-react';

When using the PRO version, you can keep it even shorter, as you would only need the proKey.

<AddToCalendarButton proKey="prokey-of-your-event"></AddToCalendarButton>

All options and hidden features

Find all information about the available props and how to configure specific features on the demo page at

Mind the difference to the web component! At this wrapper, you would use the <AddToCalendarButton> component instead of the <add-to-calendar-button> custom element.

Also mind that, different to the main package, with the React wrapper, you can actually declare arrays (like with the options prop) as arrays and objects (like with multi-date setups) as objects!
