To setup the application, first install the dependencies:
$ cd nodejs
$ npm installThe application expects to find Redis at localhost on port 6379 with no password. These are the default values when installing Redis.
If your Redis server is located elsewhere and/or requires a password, set the value of the REDIS_URL environment variable to a valid Redis connection URL before starting the application. For example:
$ export REDIS_URL=redis://simon:sssssh@redis.mydomain.com:6390Start the application as follows:
$ npm run devThis uses nodemon which will restart the application for you automatically every time you make a code change.
