Autowire is an ultra-lightweight dependency injection framework built into lambdragon.

Instead of introducing a whole new set of annotations and concepts, it relies on the type system and simple conventions.

A Basic Example

The API for the framework is very simple:

• There is just one function called autowire
• You use it to create instances of classes
• If a class has constructor parameters, autowire will try to figure them out for you

For example:

class Foo {
  constructor(bar: Bar){}
}
class Bar {}

// without autowire
const foo1 = new Foo(new Bar())

// with autowire
const foo = autowire(Foo)

• Autowire doesn't need any special @inject annotations
• It leverages the type system (including interfaces)
• Autowiring happens at compile time

class Foo { constructor(bar: Bar, baz: Baz){} }
class Bar {}
class Baz { private constructor(){} }

// this will throw a compile-time error since Baz has a "private" constructor
const foo = autowire(Foo)
