Library for DI with global container underhood

This library was inpired by AngularJS

  npm i inject-dependency

---

Typescript Example:

    import {Context, singleton, injectable, dependencies, lazyInject, fabrica} from 'inject-dependency'

    @singleton
    @injectable()
    class A {
      @lazyInject<C>('C', a => a.c.hello())
      c: C;

      hello() {
        console.log('A');
      }
    }

    @singleton
    @dependencies(A)
    @injectable()
    class B {
      constructor(public a: A) {}

      hello() {
        console.log('B');
      }
    }
    @singleton
    @dependencies(B)
    @injectable('C')
    class C {
      constructor(public b: B) {}

      hello() {
        console.log('C');
      }
    }

    const cInstance = Context.resolve<C>(C);

    cInstance.b.a.hello();
    cInstance.b.hello();
    cInstance.hello();

    /*
      A
      B
      C
      C
    */

ES7 Example:

    import {Context, singleton, injectable, dependencies, lazyInject, fabrica} from 'inject-dependency'

    @singleton
    @injectable()
    class A {
      @lazyInject('C', a => a.c.hello()) 
      c;

      hello() {
        console.log('A');
      }
    }

    @singleton
    @dependencies(A)
    @injectable()
    class B {
      constructor(a) {
        this.a = a
      }

      hello() {
        console.log('B');
      }
    }
    @singleton
    @dependencies(B)
    @injectable('C')
    class C {
      constructor(b) {
        this.b = b
      }

      hello() {
        console.log('C');
      }
    }

    const cInstance = Context.resolve(C);

    cInstance.b.a.hello();
    cInstance.b.hello();
    cInstance.hello();

    /*
      A
      B
      C
      C
    */
