Welcome to the anti-framework
engine4 is an "anti-framework", a framework that does not require you to work in a particular way or to subscribe to a particular methodology. There is no MVC, no MVVM. It doesn't drop twenty plus directories into your application or make you do anything you don't want to do.
Out of the box, it is completely file based, has zero-configuration requirements, and runs incredibly quickly.
engine4's only job is kickstart your development with a core library to handle the job of pulling the various parts of your application together, a set of selected common libraries to save you time in picking and choosing 3rd party components, and a set of "helper" classes to take the pain out of day-to-day tasks.
engine 4 features
Out of the box, engine 4 is completely file based. Mix HTML, plain-text, and markdown files to create your site or application however you want to.
engine4 has a variable structure and workflow. You can use a design pattern, such as MVC, or just hack your way to victory. Work in the way you want and customise the framework or follow the well-defined examples in the documentation.
Fast and Light-Weight
engine4 doesn't carry any baggage with it and contains only the tools you need to get the job done.
engine4 includes hand-picked 3rd party libraries, documentation and code samples, but you can drop them all and take just the framework with you if that's all you need.
