Google-calendar integration

To help beekeepers do 📅Varroa Treatment diary and plan their events without the need of using our app all the time, we should integrate popular google calendar to synchronize events

User story: (dis-) connecting service

• I go to web-app → settings page → google integration
  • Ask our 🔲Designer (UX / UI / Industrial) to design google integrations page, or do yourself

• I click Connect button to authorize access to google API and user’s calendar data
  • it will need permissions to add/edit/delete events in calendar
  • proficiency with OAuth is needed here
  • we should be able to reuse some code and experience in user-cycle that does user-cycle - Login with google
  • after OAuth process, we should store google tokens in our DB [table and service t

• If I authorized google calendar access, I get redirected back to same page, now instead of Connect button, I should see Disconnect
  • if I press Disconnect, we should cleanup stored tokens

• Once we get tokes and access, we should select which calendar we use for our events in case user has multiple calendars, for example in google calendar I mean these below →

User story: event sync

• When user adds a new event in 📅Varroa Treatment diary or 📅Calendar view (of events, treatments, alerts), we should synchronize this event one way → google calendar

• When user removes event that was synchronized, we should remove it → from google calendar

Two-way sync

• Allow user to have a setting. one-way-sync or two-way-sync.
  • In case of two-way sync, we would need to delete event from our system if user deletes it from google calendar. Research needed if this is doable and if there will be any side effects
