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
My DI Container
It's my own implementation PSR-11 Container Interface.
Installation
Init
Resolvers
ClassResolver- defines namespaces, that are allowed to autowireParameterResolver- defines scalar parameters, that can be set to constructorsDefinitionResolver- defines paths to definitions
You can implement your resolvers in a project if you need them. Look at the Interfaces namespace.
ClassResolver
Only classes from defined namespaces can be autowired.
ParameterResolver
Typical usage:
Expected behaviour:
Parameter with default value does not have to be resolved by the config:
You can create a specific resolver in your way and use it in your project. Just implement ParameterResolverInterface
and specify it during container construct.
DefinitionResolver
Attach definitions to container.
Definition, there is no more than a factory that creates an object in a specific way. There is one
specific ReflectionClassDefinition that constructs classes by their reflections. All autowired classes use that factory
to create their object.
You should create as many definitions in your project as you need and specify them during container construct or attach
them later by $container->addDefinition() method. Any definition must implement DefinitionInterface.
Typical definition class looks like this:
You can fetch some default parameters from the ParameterResolver:
Also, you can find out from which context it was called. It may be useful for autowire interfaces:
Exceptions
