TerraFab

Prerequisites

  • Node.js 0.10.x or newer

Getting up and running

You need the graphics library Cairo installed. Cairo needs to be linked with freetype to work with node_canvas for some reason. A simple way to achieve this if you are using homebrew on OS X is to install Cairo without X11-bindings, like so:

$ brew install cairo --without-x

Then:

    $ npm install
    $ node server.js

The web app should now be accessible at http://localhost:3000

Configuration

All configuration can be done under ./config/app.json. Have a look at the ./config/app.example.json.

In order to configure the accessToken and accessTokenSecret for Shapeways, you may obtain them by calling the route /accesstoken in the app after you have configrued the consumerKey and consumerKeySecret for your Shapeways application.

Model endpoints

/preview

Packages the model into an archive ready for export.

/download

Download the built model archive.

/cart

Lets the user buy the model at Shapeways through our configured Shapeways application.

It assumes the user already have visited the /preview route.
