Basic library to create an IoC (Inversion of Control) container with service providers. Supports Transient and Singleton services and dependencies.

Services are registered with the ServiceProvider, which is used to generate the IoC Container. The registerXXX method takes as arguments

key {string} : Identifier for service.

serviceClass {class} : Implementation class for service, serviceClass should have a constructor that matches the dependency list.

dependencies {Optional[Array<string>]} : List of service keys that will be used to initialize serviceClass. Dependencies should be passed in the order of constructor arguments.

let serviceProvider = new ServiceProvider();

serviceProvider.registerSingleton("ConsoleWriter", CustomConsoleWriter);
serviceProvider.registerTransient("Printer", PrettyPrinter, ["ConsoleWriter"]);

let container : IoCContainer = serviceProvider.generateContainer();

let prettyPrint = container.getService("Printer");
prettyPrint.out("Hello World!")
