twister
Twister is a fast and light-weight micro-framework.
Actually, a more precise definition of this code would be;
Twister is a set of fast and light-weight components around which a framework can be written
At the heart of the framework, sits a very flexible, simple and elegant Inversion-of-Control (IoC) Container.
In fact, there are NO global variables, NO define's, NO pipeline, NO Kernel and NO App; just the Container.
The Container controls the entire flow of code (except routing), with a custom execute() function (written by you);
which is actually just an anonymous callback function inside the Container, called from the Front Controller (index.php);
even the name of that function can be changed in the config file.
ie. There is NO pre-programmed flow of the program or hard-coded Kernel/App.
Most things are handled/registered with the IoC Container, objects are pre-configured and lazy-loaded on request/use only!
Along with the Container, comes a very flexible and fast router (inside the Request class).
I consider this router to be THE fastest router I've tested, with the same functionality.
It includes the ability to filter by method (GET/POST), and optional parameters like /user/{id}[/{name}]
Another somewhat unique capability is the ability to pre-define the patterns associated with named parameters eg. id->\d+
So everytime you specify {id}, {date} etc. in any route, the same patterns are re-used,
or you can specify custom patterns with {id:[0-9]+} or {id:uuid} where 'uuid'=>'[A-F0-9-]+' etc.
Two design choices make the router fast:
1) Everything is configured/loaded from a config array (which is usually cached by APC/Xcode/PHP7)
2) The router splits the request uri by '/', doing an isset array lookup for the first path segment
3) The router only takes further action after the first segment (eg. /admin/, /login etc.) is resolved
Although Twister is a fully functional and useable framework (based on my personal framework), it's more a proof-of-concept for me to demonstrate my capabilities and design decisions.
Benchmarks:
All tests were done with a skeleton hello world application on the same PC.
Laravel and Symfony were NOT configured to establish a database connection, while Twister WAS!
With a database connection, Symfony dropped to 9~12 requests per second, and Laravel 12~16 rps,
Twister was running about 50x~100x faster than Symfony and Laravel
