figure out a way to initialize games using CryptoCompare

• Usage: /api/capcoin/gameId/userId should return the user's CapCoin data at 15-minute intervals for this game specifically

Either correct use of Heroku automatic scheduler or find a different one for creating/closing CoinDuel games

https://devcenter.heroku.com/articles/scheduled-jobs-custom-clock-processes

^apparently a better and more reliable alternative to scheduler. even heroku's own website states that scheduler is free and can commonly miss or duplicate tasks and is unreliable for scale.

-Create endpoints to categorize and send data to display HQ style leaderboard for frontend.

• See: dartmouth-cs98/18w-CoinDuel-frontend#84

A little vague for now, but will become clearer as term progresses.

https://min-api.cryptocompare.com use this for all coin price/historical data for consistency

Setup app on heroku to allow connection between backend/frontend

Create necessary endpoints and models/routes to interact with Heroic mongo backend

Clean up any unused endpoints or combine endpoints between the Game and Leaderboard controller to make the flow more efficient

Previously /coin/TICKER returned "price" and "name" as values, now it only returns the price as a number

• Every 15 mins, should update every user's CapCoin balance for both (1) all-time CapCoin balance and (2) current game CapCoin balance
• Needs to be stored on backend for use in #37 and #40

Usage:

• /api/capcoin/userId/ outputs CapCoin data for that user at 15 minute intervals going back all-time

might want to not send back the plaintext passwords. not a huge deal but if someone is looking for something to clean up, comparing salted+hashed passwords is the way to go, where you can't ever decrypt it. as this progresses probably you'll want to add in auth tokens - as your routes could be hacked pretty easily without that.

getAllTimeRankings (api/leaderboard) returns {"error":{}} if there is no game in the database with finish_date greater than the current date

Perhaps implement our own scheduler to create new games instead of using Heroku's

Essentially create a PUT endpoint to add a new user to our app

Deploy backend for api calls

• Every week, sometime before a game ends, the next week's game should be created with appropriate date time for start and finish
• Close out the games when they end by updating entries to set CapCoin return (says percent_return right now but should be in CapCoin)

Specific errors are not caught on signup - custom error messages should be sent back.
