This is a minimal Web development framework. Instead of downloading thousands of packages from NPM, it builds on a template engine (Handlebars), a DOM manipulation library (jQuery), and a JavaScript transpiler (Babel).
Single page applications are built from single file components, which are XML files containing a) a template section, b) a script section and c) a style section. All programming is done in pure, object-oriented JavaScript.
Since Snazzy apps are hand-crafted, they tend to be small -- meaning they load swiftly and run efficiently.
