> Twister is a fast and light-weight micro-framework component library
|
|
|
|
|
|
|
|
|
|
|
|
Another definition of this code release would be;
|
|
|
|
|
|
> Twister is a set of fast and light-weight components around which a framework can be written
|
|
|
|
|
|
|
|
|
|
|
|
There is also a [skeleton application](https://github.com/twister-php/skeleton) based on this code!
|
|
|
|
|
|
|
|
|
|
|
|
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}`, `{uuid}` etc. in the routes, the pre-configured patterns are 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:
|
|
|
|
|
|
* Everything is configured/loaded from a `config` array (which is usually cached by APC/Xcode/PHP7)
|
|
|
|
|
|
* The router splits the request uri by '/', doing an `isset` array lookup for the first path segment
|
|
|
|
|
|
* 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
