Variables

var ENV = envy.Get("GO_ENV", "development")

ENV is used to help switch settings based on where the application is being run. Default is "development".

Functions

func App

func App() *buffalo.App

App is where all routes and middleware for buffalo should be defined. This is the nerve center of your application.

Routing, middleware, groups, etc... are declared TOP -> DOWN. This means if you add a middleware to `app` *after* declaring a group, that group will NOT have that new middleware. The same is true of resource declarations as well.

It also means that routes are checked in the order they are declared. `ServeFiles` is a CATCH-ALL route, so it should always be placed last in the route declarations, as it will prevent routes declared after it to never be called.
