If "areas" is coming back undefined it probably means that the data wasn't added to the database.

Before running the server you need to run:

node addtodb.js

And wait about two or three minutes for all the information to get added. Sorry there is no output to tell you when the process is done.

whenever I tried to Run addtodb.js in gives me this msgs.

node_redis: Deprecated: The SADD command contains a argument of type ObjectID. This is converted to "573eb7e97ab2208a0bba5f8c" by using .toString() now and will return an error from v.3.0 on. Please handle this in your code to make sure everything works as you intended it to.

Okay, I just updated the addtodb.js script. It should work without error and also give more useful output.

Also if you run the script multiple times you might need to delete the information already added to mongodb and redis or you will have a lot of duplicates.
