The convenient JavaScript snippet, which lets you reliably create beautiful buttons, where people can add events to their calendars.
For everybody, who wants to include a button at their website or app, which enables users to easily add a specific event to their calendars. It's main goal is to keep this process as easy as possible at maximum compatibility. Simply define your button configuration and everything else is automatically generated by the script. Supporting calendars at Apple, Google, Microsoft (365, Outlook, Teams), Yahoo, and generic iCal.
The script integrates easily with any usual HTML webpage (VanillaJS way) as well as popular JavaScript frameworks and libraries like Angular, React, Vue, Svelte, and more.
In terms of system support, all modern browsers (Chrome, Edge, Firefox, Safari) on Windows, Mac, Android, and iOS as well as rather restricted webview environments like the Instagram in-app browser are supported.
See add-to-calendar-button.com for a live demo.

You can use the jsDeliver CDN and load the respective ressources into your web project.
Put the css (use atcb-3d for an alternative style) into the <head>:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/add-to-calendar-button@1/assets/css/atcb.min.css">
... and the javascript into the <body> footer:
<script src="https://cdn.jsdelivr.net/npm/add-to-calendar-button@1" async defer></script>
Mind that this always pulls the latest release of v1! You can pin a more specific version by adding the exact version number after the "@" - see jsDeliver.com for details. If you want to rather host it yourself, you could also download the source files or clone the repository (mind to take the original one at github.com/add2cal/add-to-calendar-button) and maintain/update it manually.
Import the package using the following npm command:
npm install add-to-calendar-button
Import the module into your project/component. For example with Angular/React:
import { atcb_action, atcb_init } from 'add-to-calendar-button';
Either use atcb_action with your own buttons/forms/etc, or run atcb_init after the DOM has been loaded. To determine the right moment to execute the atcb_init, ...
- with Angular, you would use
ngAfterViewInit()withatcb_init();(mind that, depending on your app, other hooks might be better); - with React, you might want to include an event listener for
DOMContentLoadedor use a hook in a functional component likeuseEffect(() => atcb_init());.
Include the css. For example with Angular or React, add @import 'add-to-calendar-button/assets/css/atcb.css' to some other css file - or include it in other more direct ways (like adding import 'add-to-calendar-button/assets/css/atcb.css'; to the respective component) (use atcb-3d for an alternative style).
A button can be easily created by placing a respective placeholder, wherever you want the button to appear.
(The style="display:none;" theoretically is not necessary, but should be used for better compatibility.)
<div class="atcb" style="display:none;">(...)</div>Within this placeholder, you can easily configure the button, by placing a respective JSON structure.
Mind that with Angular, you might need to escape the { with {{ '{' }} and } with {{ '}' }}; with React it would be { '{' } and { '}' }.
If there is no endDate set, the script assumes that it is the same as startDate.
Mind that for auto-generating rich snippets, a location would be mandatory as well. Even a timezone is not required, but recommended - if not given, the script will assume UTC.
<div class="atcb" style="display:none;">
{
"name":"Add the title of your event",
"startDate":"2022-02-21",
"options":[
"Google"
]
}
</div><div class="atcb" style="display:none;">
{
"name":"Add the title of your event",
"description":"A nice description does not hurt",
"startDate":"2022-02-21",
"endDate":"2022-03-24",
"startTime":"10:13",
"endTime":"17:57",
"location":"Somewhere over the rainbow",
"label":"Add to Calendar",
"options":[
"Apple",
"Google",
"iCal",
"Microsoft365",
"MicrosoftTeams",
"Outlook.com",
"Yahoo"
],
"timeZone":"Europe/Berlin",
"trigger":"click",
"inline":true,
"listStyle":"modal",
"iCalFileName":"Reminder-Event"
}
</div>If you can't or don't want to use atcb_init, you can use the atcb_action import with your own buttons or other elements/components.
This may work better with React and other frontend frameworks, but it misses the Schema.org and button specific functionalities.
import React from 'react';
import { atcb_action } from 'add-to-calendar-button';
const MyComponent = () => {
const [name, setName] = React.useState("Some event");
const changeName = e => {
setName(e.target.value);
};
return (
<form onSubmit={e => {
e.preventDefault();
atcb_action({
name: name,
startDate: "2022-10-14",
endDate: "2022-10-18",
options: ['Apple', 'Google', 'iCal', 'Microsoft365', 'Outlook.com', 'Yahoo'],
timeZone: "Europe/Berlin",
iCalFileName: "Reminder-Event",
});
}}>
<input value={name} onChange={changeName} />
<input type="submit" value="save" />
</form>
);
}Alternatively, you could use atcb_init with a useEffect hook:
import React from "react";
import { atcb_init } from "add-to-calendar-button";
import 'add-to-calendar-button/assets/css/atcb.css';
const MyComponent = () => {
React.useEffect( () => { atcb_init() }, []);
return (
<div className="atcb">
{ '{' }
"name":"Add the title of your event",
"description":"A nice description does not hurt",
"startDate":"2022-02-21",
"endDate":"2022-03-24",
"startTime":"10:13",
"endTime":"17:57",
"location":"Somewhere over the rainbow",
"label":"Add to Calendar",
"options":[
"Apple",
"Google",
"iCal",
"Microsoft365",
"Outlook.com",
"Yahoo"
],
"timeZone":"Europe/Berlin",
"iCalFileName":"Reminder-Event"
{ '}' }
</div>
);
}By the way: Both functions return an array, holding the IDs of the generated buttons!
