cfn-builder is a NodeJS command line application that will convert your JSON "blueprints" to an AWS CloudFormation template.
The idea behind this project is to create a small number of JSON & Handlebars (.hbs) files (aka Blueprints) that can be compiled into a larger number of CF templates. Each project has multiple JSON files describing a particular environment (i.e. Prod, QA, Dev) which is then compiled against a general blueprint which results in a CloudFormation template that can be executed.
