ShiftScheduler

A Blazor WebAssembly application for managing work shift schedules with calendar export and transport integration.

Overview

ShiftScheduler is a web-based shift management system that allows users to:

• Plan and visualize work shifts using a monthly calendar interface
• Export schedules to ICS and PDF formats
• Sync shifts directly to Google Calendar or Nextcloud Calendar
• View optimal transport connections for work commutes
• Secure access through Google OAuth authentication

Key Features

Calendar-Based Shift Management

• Monthly calendar view with day-by-day shift assignment
• Toggle between current and next month
• Mobile-friendly week layout alongside the desktop grid view

Export & Sync

• ICS Export: Download a calendar file compatible with any calendar application
• PDF Export: Generate a printable monthly schedule
• Google Calendar Sync: Direct sync to a selected Google Calendar; existing app-managed events are updated, other events are untouched
• Nextcloud Calendar Sync: CalDAV-based sync to a selected Nextcloud calendar

Transport Integration

• Calculates optimal departure and arrival times for work commutes
• Integrates with the Swiss public transport API (transport.opendata.ch)
• Displays morning and afternoon connections alongside each shift
• Configurable safety buffers and break durations

Authentication

• Google OAuth 2.0 with a configurable list of authorized email addresses

Configuration

• Shift definitions (name, emoji icon, morning/afternoon time ranges) managed via the in-app configuration dialog
• Transport settings (stations, API URL, timing buffers) configurable in-app
• Configuration can be exported and imported as JSON for backup
