I just finished reading the entire book.
By: Simon Holmes
Read On: O'Reilly
In Paperback: 440 pages
Publisher: Manning Publications (December 1, 2015)
I swapped Google maps for OpenStreetMap's using leaflet.js, it's my anti-google-isms.
You won't be able to use MongoLab's much longer, I used MongoAtlas to connect to Heroku... worked fine. Also geoNear has changed so that was a bust, I got it working but not as the author intended, I fiddled far to long on that section.
All and all I love Manning books, always so thorough, great read if you're in the reading zone.
No git repo for this one, I used Mr. Holmes' as they were in easy to pull branches.
