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 lean
Lean
Lean allows you to use the PHP League's Container package with auto-wiring support as the core container in Slim 3.
Install
Via Composer
Usage
The easiest way to start using Lean is simply creating a Jenssegers\Lean\App instance:
Behind the scenes, a Slim application is bootstrapped by adding all of the required Slim components to League's container.
Service Providers
Service providers give the benefit of organising your container definitions along with an increase in performance for larger applications as definitions registered within a service provider are lazily registered at the point where a service is retrieved.
To build a service provider it is as simple as extending the base service provider and defining what you would like to register.
To register this service provider with the container simply pass an instance of your provider or a fully qualified class name to the League\Container\Container::addServiceProvider method.
Read more about service providers here.
Settings
You can access Slim's internal configuration through the settings key on the container:
Alternatively, an alias is registered that allows a bit more fluent way of working with settings:
Read more about the available configuration options here.
Route arguments
By default, Lean will use method injection to pass arguments to your routes. This allows you to type-hint dependencies on method level (similar to the Laravel framework).
Route arguments will be passed as individual arguments to your method:
They are also accessible through the getAttribute method.
If you want to disable this behaviour and use the default Slim way of route arguments, you can disable this feature be setting methodInjection to false:
Read more about routes here.
Error Handlers
By default, Lean uses Slim's error handlers. There are different ways to implement an error handler for Slim, read more about them here.
Typically you would create a custom error handler class that looks like this:
Then you overwrite the default handler by adding it to the container:
Ideally, you would put this code inside a service provider. Read more about service providers above.
