gt-local-calendar-sync

A simple calendar syncing system that keeps a local cache of calendar events that sync to Google Calendar API.

Devise and implement a simple cache system that allows an endpoint that serves a list of calendar events from a logged in user's Google calendar while limiting the number of API hits to Google Calendar by holding a local cache of events.

Guidelines

The cache can be built in any way you see fit as long as it persistants beyond server restarts.
Response of GET request should return JSON

Requirements

The server should respond to the following request via JSON in the format of the sample output below

GET /calendar-events

If the user is not logged in, redirect to login page for Google Calendar to authorize user. After auth, redirect to /calendar-events endpoint
Show a list of upcoming calendar events with event data:
- Event Title
- Event Description
- List of Attendees (with attendance reponse)
