Wayfinder is the second web application I built in a node.js/express.js framework. I completed the initial prototype in about 9 days.
How it Works
Wayfinder enables its users to build and share maps as a way of telling their stories about living in and visiting places around the world. Users can also learn from others by viewing the maps others have created. Anyone can browse user-created maps, but you must create an account to build your own.

Built in a node.js/ExpressJS framework using a PostgreSQL for data storage. Also makes extensive use of the Google Maps API.
