FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package container
Everest - Container
This Everest component handles Dependency Injection. It's inspired by the AngularJS injector and Pimple\Container.
Usage
Injection
Dependencies can be injected into services and factories using a dependency array ['dependencyA', 'dependencyB', $callableOrClassname] where the dependecies will be given to the callable or the class constructor as arguments.
A (slower) way is using the parameter names of the callable or constructor to specify the dependencies. E.g. function($dependencyA, $dependencyB) {...} has the same result as ['dependencyA', 'dependencyB', function($depA, $depB) { /*...*/ }].
Note: This does not work with inner callbacks!
Constant
Constants can be defined using the self Everest\Container\Container::constant(string $name, mixed $value)-method.
Note: Constants are available during the provider configation cycle!
Values
Values can be defined using the self Everest\Container\Container::value(string $name, mixed $value)-method.
Factory
Factorys can be defined using the self Everest\Container\Container::factory(string $name, mixed $factory-method.
Service
Services can be defined using the self Everest\Container\Container::service(string $name, mixed $service)-method.
The service-method expects a class name or a dependency array with the class name as last element as argument. E.g. ['dependencyA', 'dependencyB', 'Vendor\\Project\\Service'] or just (slower) 'Vendor\\Project\\Service' where the parameter names of the constructor are used to inject the dependencies.
Decorator
You can use the self Everest\Container\Container::decorator(string $name, mixed $decorator)-method to overload existing dependencies while receiving the original instance as local dependency. Decorators MUST be a factory or a provider.
Provider
A provider can be any object having the public property factory describing the factory as dependency array. A provider can be set using the self Everest\Container\Container::provider(string $name, object $provider)-method.
Providers can be accessed during configuration process by using their name with Provider suffix as dependency.
