Visualizing nutrition facts, a project started at #code4health. This is built with the Haskell SnapFramework.

Charts are made with javascript code that renders SVG files.

#Installation

Install GHC from haskell.org/platform. It should be the latest. At the time of this writing the latest version is GHC 7.6.3. It comes with cabal, which is a package manager that helps you install packages from hackage.

The .cabal file lists dependencies.

You also need to install postgres.

#Usage

1. Sign up for API accounts at Instagram, Jawbone Up, and FatSecret.
2. Create a configuration file that lists the api secret keys.
3. Build and run server

$ cabal build
$ createuser postgres
$ createdb testdb
$ dist/build/codeforhealth/codeforhealth

Developer Note: if you will be editing files, use the fswatch library to automatically reload your app. The command to watch for changes is shown below. Template places are saved in snaplets/heist/templates directory and media files saved in static.

$ fswatch snaplets/heist/templates:static "curl http://localhost:8000/heistReload"
