README

Every morning you get an email with the top tweets from yesterday. On the website you can further view all yesterday's tweets, sorted by popularity. It's Twitter in pure and focused form that doesn't suck you into a rabbitwhole of endless comments and threads.

Prerequisite

Twitter developer app

First create a twitter app here: https://developer.twitter.com/en/apps

Configure the callback url to https://[your-hostname]/auth/twitter/callback

Note the API key and API secret key.

Encryption string

Consumer keys for signed up twitter users are encrypted before stored in the database using a 256 bit encryption string (https://github.com/attr-encrypted/attr_encrypted#usage).

You need to generate this string and you can use the following ruby code:

require "securerandom"
SecureRandom.alphanumeric(32)

This will be the key for encrypting/decrypting twitter consumer keys so be careful of it.

Running the app locally
