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.

Installation
| Manager | 3.* | 2.* | 1.* |
|---|---|---|---|
| php ^8.1 | :white_check_mark: | :x: | :x: |
| php 8.0.* | :white_check_mark: | :white_check_mark: | :x: |
| php 7.* | :x: | :x: | :white_check_mark: |
Usage
This package offers an abstract class DeGraciaMathieu\Manager\Manager which needs to be extended to implement the creation of various Driver classes :
A driver is a class integrating all the logic of an implementation, in our examples the interactions with the APIs of Openweathermap :
From now on, you can directly call the method of a driver directly from the manager :
The manager will call the itsRainingNow method of the default driver configured by the getDefaultDriver method.
You can also call any driver from the manager's driver method :
Now if you want to create a new implementation, for example if you want to use Aerisweather APIs, you just have to create a new driver in your manager :
Tip, the
getDefaultDrivermethod is the perfect place to use a configuration or environment variable !
Add an interface to the drivers
For more consistency it is advisable to implement an interface to the different drivers :
You obviously need to add this interface to your drivers.
Now you will be assured that each driver instantiated by the manager will have the same interface.
Repository class
To control side effects of drivers, it is advisable to create a class encapsulating the instance of a driver, this class is usually called Repository :
The repository is a class providing a bridge between your application and the driver :
This repository class is an anti-corruption layer
Thus, your application will never be aware of which driver it is handling, because it will always be encapsulated in a class repository.
The repository is also a good place if you need to add specific logic for all drivers.
Work with singleton
You can also cache the creation of Drivers with the $singleton property.
With the singleton property you will only create one instance of Openweathermap driver :
by default, singleton property value is False
