Waker

The general workflow of Waker is:

• Call server endpoint to return the host and port(s) of a server
• After returning the server info, check to see if it’s up
• If it isn’t, post a status on the Twitter bot (limited to every half hour)

Libraries

• service-checker: used to check if a server is up (using rawTcp)
• twit: twitter bot framework
• express: basic REST server
• dotenv: storing config options as process environment variables
• geoip-lite: getting physical server locations for Eyes
• others: moment, log4js, lodash
