Injector 是一个用于 TypeScript 和 JavaScript 应用程序的控制反转 (IoC) 容器。

import { ValueProvider, injectable, inject, injector } from '@unicreators/injector';

@injectable()
class B { }

@injectable()
class A { constructor(public b: B, @inject('value1') v1: number) { } }

injector.register(new ValueProvider('value1', 10));

let a = injector.get<A>(A);
let b = injector.get<B>(B);

expect(a).instanceOf(A);
expect(a.b).equals(b);
expect(a.v1).equals(10);
