RonSijm.Syringe 0.2.1

RonSijm.Syringe

A library for to make it easier to do dependency injection.

Get it? A Syringe is used to inject things. Yes jokes are better when you have to explain them...

Default ServiceCollection Extensions:

Extension Methods

By doing a WireImplicit - The extension will return a SyringeServiceCollectionAndRegistration object. This is an object that keeps track of the last registion that you've made, allowing you to append extra configuration to that specific registration:

<a id='snippet-CodeExample-DontRegisterTypesExtension'></a>

var serviceCollection = new SyringeServiceCollection();
serviceCollection.WireImplicit<ClassA>().DontRegisterTypes(typeof(ClassA));

^{<a href='/src/Tests/RonSijm.Syringe.Tests/Features/Tests/MicrosoftServiceProvider/CustomCollection/Parameters/TestWireImplicit_DontRegisterAsTypes_Class.cs#L11-L14' title='Snippet source file'>snippet source</a> | <a href='#snippet-CodeExample-DontRegisterTypesExtension' title='Start of snippet'>anchor</a>}

<a id='snippet-CodeExample-DontRegisterTypesWithInterfaces'></a>

var serviceCollection = new SyringeServiceCollection();
serviceCollection.WireImplicit<ClassA>().DontRegisterTypesWithInterfaces([typeof(InterfaceFor_ClassWithInterfaceA)]);

Registration Extensions

A SyringeServiceCollection contains a internal List<IWireSyringeServiceDescriptorExtension> Extensions { get; set; } = []; - which lets you add your own BeforeBuildServiceProvider Extensions

Example

You can put these kind of configurations in your appsettings.json:

Don't register classes with this interface:

Usecase:

Imagine you have an IProcessor (Interface), DatabaseProcessor and APIProcessor that implement this interface - In your appsettings.json you can register or unregister a specific implementation for this interface.

<a id='snippet-CodeExample-ConfigurationNotWithInterfaces'></a>

var appsetting = """
                 {
                     "DependencyInjection": {
                         "Assembly:RonSijm.Syringe.ExamplesC": {
                         "Type:ExampleCInterface": "None"
                         }
                     }
                 }
                 """.ToConfiguration();

^{<a href='/src/Tests/RonSijm.Syringe.Tests/Features/Tests/MicrosoftServiceProvider/Registration/Config/ExamplesC_InterfaceRegistrationNone.cs#L11-L23' title='Snippet source file'>snippet source</a> | <a href='#snippet-CodeExample-ConfigurationNotWithInterfaces' title='Start of snippet'>anchor</a>}

Don't register these specific classes:

Usecase:

Imagine you have an IProcessor (Interface), DatabaseProcessor and APIProcessor and UserProcessor - In your appsettings.json you can register or unregister a specific implementations for this interface.

When your consumer takes an IEnumerable<IProcessor> - you can register or unregister specific processors, and only run selected processors.
