Shorty is a simple URL shortener demonstration project made up of:

• A Python Pyramid + SQLAlchemy + React UI (shorty_ui)
• A Node.js app to resolve short URLs (shorty_resolver)
• MySQL for persistent storage
• Memcached to cache the short-to-long URL map

Prerequisites:

• Python 2.7, working in a virtualenv with $VENV set accordingly
• MySQL 5 installed and running, with a "shorty:shorty" user created
• Node.js 0.10
• Memcached listening on localhost 11211

In the shorty_ui directory:

% $VENV/bin/python setup.py develop
% $VENV/bin/python initialize_shorty_db development.ini
% $VENV/bin/pserve development.ini

In the shorty_resolver directory:

% npm install mysql
% npm install node-mysql
% npm install memcached
% node resolver.js

You'll have two webapps running:

• The web UI for adding URLs at http://localhost:6543
• The short URL resolver at http://localhost:7654

• Build initial Pyramid app with SQLAlchemy scaffolding
• Build initial Node.js resolver app
• Initial docs
• Document scalability issues - (see scalability)
• Add URL caching via memcached
• Add React (+ Bootstrap) UI to Pyramid app
• Add basic URL metrics
• Add user/account management
• Expose API
