Frack is a small example implementation of how to build a simple MVC style application from scratch. Check out the commit history to see how I implemented it step-by-step.
It obviously lacks a lot of features compared to something like Rails and should not be used for production. But for serving simple dynamic pages it should be fine.
When you clone the repo bundle and rackup should be enough to get the application running.
Then point your Browser to localhost:9292.
If you found to this repo because of my talk, you may want to dive deeper.
Rebuilding features you get for free in Rails, is a great opportunity to learn how all this stuff works.
I for example, had a lot of fun inside the rabbit hole of ActionView, figuring out how render is implemented.
So here is an incomplete and unordered list of possible extensions:
- render partial: 'foo'
- render different formats
- implicit call to render
- routing with placeholders
- routing with specific http verbs
- error handling
- session management
- flash messages
- persistence
- security stuff and protection
- different mime types
- url helper
- better class loading / autoloading
- asset management
