Viper
Viper is a lightweight universal PHP MVC framework with its own models and templating engine, (*1)
Starting developing on Viper is as easy as typing in the console:, (*2)
composer create-project arsengoian/viper PROJECT_NAME dev-master
and configuring DB credentials., (*3)
To check out the application build which is deployed with this command (or contribute) check out: https://github.com/arsengoian/viper, (*4)
Configuration
The web application is configured by an array of YAML files at config/ directory. They contain a list of instructions on every setting. local.yaml contains configuration related to the current server environment while global.config sets up overall application settings., (*5)
Settings may be accessed at any time using Config class:, (*6)
if (Config::get('DEBUG')) // From local.yaml -> local.yaml and global.yaml don't need a preffix
return Config::get('Bots.VERIFY_TOKEN') // From bots.yaml
Features
YAML routing
Requests are routed automatically, for example a GET request to http://website.com/chairs will invoke the get method of ChairsController, (*7)
Routing example:, (*8)
welcome: DefaultController # directs DOMAIN/welcome -> DefaultController::get($http_params)
hello: DefaultController.main # directs DOMAIN/hello -> DefaultController::main($http_params)
products: # 1-level hierarchies are also supported
parse: DefaultController
count: DefaultController.main
Easy-to-use controllers and built-in validation
A controller function implementing a POST request:, (*9)
public function post (...$args): ?Viewable
{
$v = new Required($this -> params()); // Create validator
$v -> email('email'); // Validate "email" field
Client::registerWithImages($this -> params(), $this -> files()); // Create new model in the database
return new RedirectView('/'); // Redirect to main page
}
Auto-completing models
Viper deals with databases automatically, miminizing the need to edit SQL manually. A YAML setup like this:, (*10)
allowOverwrite: true
fields:
fname: VARCHAR(255) NOT NULL
lname: VARCHAR(255) NOT NULL
email: VARCHAR(255) NOT NULL
age: INT NOT NULL
img: TEXT NOT NULL
will create the needed database structure if needed and update it along with the file if needed., (*11)
Filters
Will be applied to all routes before any controller actions:, (*12)
class Application extends \Viper\Core\Application
{
/**
* Defines the list of filters to be run
* before any controller actions
* @return FilterCollection
*/
protected function declareFilters (): FilterCollection
{
return new FilterCollection([
LocalizationFilter::class,
Authorization::class
]);
}
}
Logging and utilities
Viper supports built-in logging and a collection of useful utilities, including caching, advanced string handling etc., (*13)
Caching capabilities
All views and parsed .yaml files are recovered, if possible, from cache, (*14)
Features in early development
- Background processes and services
- Windows background tasks
- Viper templating engine
- Console commands
- Full Mysql support
- Full SQL Server support
- Other SQL dialects support
- Numerous feature and structure improvements
Contributing and development
Since the framework is on an early stage of development, it may feature structural irreversable changes without reverse compatibility., (*15)
