Technical Note: Database Architecture
This plugin integrates <code>webcalendar-core</code>, a framework-agnostic Composer library that provides all calendar business logic (events, recurrence, iCal, permissions) through 17 repository classes. These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via <code>$wpdb</code> through the plugin’s Bridge layer (<code>WpUserRepository</code>, <code>WpConfigRepository</code>, etc.). See <code>src/Bridge/PdoFactory.php</code> for the connection factory.

<h4>Remote Calendar Sync (User-Configured)</h4>
When remote iCal subscriptions are configured, the plugin fetches .ics data from 
those URLs via HTTP GET. No user data is transmitted to these services.
<h4>OpenStreetMap / Nominatim</h4>
When a single event page has a location and the map provider is set to OpenStreetMap 
(the default), the plugin geocodes the address via the Nominatim API and displays a 
map using OpenStreetMap tile servers. The event location string is sent as a search 
query. No user personal data is transmitted. 
* Geocoding endpoint: https://nominatim.openstreetmap.org/search

* <a href="https://wiki.osmfoundation.org/wiki/Privacy_Policy" rel="nofollow ugc">OpenStreetMap Privacy Policy</a>
<h4>Google Maps Embed API</h4>
When the map provider is set to Google Maps in settings, single event pages display 
an embedded Google Map for the event location. The event location string and your 
Google Maps API key are sent to Google. No other user data is transmitted. 
* Endpoint: https://www.google.com/maps/embed/v1/place

<h4>Add to Calendar Links</h4>
Single event pages include “Add to Calendar” buttons that generate links to Google 
Calendar, Outlook.com, and Yahoo Calendar. When a visitor clicks a button, the event 
title, date, time, location, and description are passed as URL parameters to the 
chosen service. No data is sent until the visitor clicks.

<h3>Development & Source Code</h3>
Full unminified source for this plugin is included in this distribution under GPL-2.0-or-later — you do not need to download anything external to rebuild the compiled assets.
What ships in this zip:
<ul>
<li><code>src/</code> — unminified React/JSX source for all admin components, frontend calendar, and the mini-calendar widget</li>
<li><code>build/</code> — the pre-compiled minified bundles (what the plugin actually loads at runtime)</li>
<li><code>package.json</code> + <code>package-lock.json</code> — Node build manifest and lockfile for reproducible <code>npm install</code></li>
<li><code>composer.json</code> — PHP dependency manifest</li>
</ul>
Rebuilding the compiled assets from source:
Prerequisites: PHP 8.2 or higher with Composer 2, Node.js 20 or higher with npm 10.
<ol>
<li><code>composer install</code> — install PHP dependencies</li>
<li><code>npm install</code> — install JavaScript build dependencies (@wordpress/scripts, React, Toast UI Calendar, Leaflet, Tiptap)</li>
<li><code>npm run build</code> — compile <code>src/index.js</code> and <code>src/frontend.js</code> into the minified bundles under <code>build/</code></li>
</ol>
The compiled output in <code>build/</code> is byte-reproducible from the matching <code>src/</code> at the same version using this toolchain.

Hello Event adds event management and ticket sales in an extremely easy way to any WordPress site! Just drop in the plugin and you’re ready to go. Welcome to the “Hello World” for events!
With this plugin you can easily create and manage events (like concerts, training camps or competitions). The events you create have fields for location, start and end dates (and optionally times for events that are not full-day events) and can be presented in different formats, both in lists and in calendars.
If you have installed WooCommerce you will be able to generate and sell tickets with a simple click. On the event page a link will point to the tickets in WooCommerce and in WooCommerce there will be a backlink from the ticket to the event. And in the backend dashboard you will immediately see how ticket sales progress for each event
Hello Event supports different date and time formats and is of course multi-lingual and currently comes with translations for English, French and Swedish. More languages will be added, and if you want to add other languages yourself, you can easily do that for example with the help of the Loco plugin.
Hello Event is iCal compatible and the event pages will display an “Add to calendar button” to allow users to insert the event into their calendars. The plugin can make use of external services to present the locations of events. For this purpose either Google Maps or OpenStreetMap may be used.
Although the plugin is perfect for use by the non-technical site creator, it is also developer-friendly with shortcodes, hooks and all styling provided by CSS that can be overridden. To get you going immediately the plugin will automatically show event-related information when a post of the “hello_event” custom type is presented. For more control, you can switch off the automatic insertion of this information and use the shortcodes provided wherever you want.
To enhance the organic SEO of your site, all pages that present events provide Structured Data descriptions of the event – see <a href="https://developers.google.com/search/docs/guides/intro-structured-data" rel="nofollow ugc">Google documentation on Structured Data</a>.
With Hello Event you can now use WooCommerce and all its different payment gateways to handle the ticket sales! Easy peasy!
