Recurse Center contact importer.
A web app were you login with your RC account, give permission to modify
your Google Contacts, and with just a few clicks you import the contacts
of whole batches.
Note: The code present on this app started as a 2-hour Monday hack, so you might find several parts of it rather naïve or even wrong. Also, this is part of my Node.js + Express.js + Jade + Passport.js learning, so the quality of the code is somewhat low.
npm install
npm start
