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 box
Box - Minimalist Dependency Injection Container
Box is dependency injection container which manage dependencies based on closure definitions only. This approch has the particularity to be simple, easy and flexible. It also support lazy dependencies resolution using wrappers.
API
Creating a Dependency container
Setting up a service
To to share a unique service over your application use Box::service(). A service can be a class, an instance, a string or any kind of value.
Example:
Each shared service defined with Box::service() can be retreived using Box::get().
Note: If a share is defined using a closure, the closure will be executed once and the result will be returned for all next Box::get() calls.
Setting up a factory
Use Box::factory() to setup a factory. It can be a closure:
Or a fully-namespaced class name.
Box::factory() will create an new instance of the definition when resolved using Box::get().
Resolving a dependency
To resolve a dependency, use Box::get():
All $paramX are optional parameters passed to the closure or directly to the constructor if the definition is a fully-namespaced class name string.
Returing a wrapped dependency
Wrapping a dependency has the advantage to allow to inject a dependency without resolving it directly. To be able to lazily resolve a dependency you need to use Box::wrap():
All $paramX are optional parameters passed to the closure or directly to the constructor if the definition is a fully-namespaced class name string.
Then dependency is resolved by doing:
All $paramX are optional and will overrides the ones setted at the wrapping step.
Cleanup
Use Box::remove('foo') to remove a specific dependency or Box::clear() to remove all dependencies.
Global API
You can use the box() function to get/set a DI anywhere in your code.
