libby

Libby - Strekmann express setup

Libby enables trust_proxy in express, if configured. Then sets up a cookieParser, logging, error handlers and sessions. Libby will also set up body-parser and method-override and ‘connect-flash’ to send messages to users through res.locals.messages. For validation, Libby sets up express-validator. Lastly, Libby sets up the translation framework i18n-abide and adds a translation shortcut to res.locals.__.

Usage
