Dependency Injection Using decorators

@Injectable

Use Injectable to declare a class as a provider. Use DependsOn to declare its dependencies.

import { DependsOn, Injectable } from "@cho/core/di";

@Injectable(DependsOn("foo", "bar"))
class MyService {
  constructor(private foo: string, private bar: number) {
    // foo and bar will be injected by the injector
  }
}

@Module

Use Module decorator to declare a module. Module is a logic container for providers. Module can import other modules to access their providers.

import { imports, Injectable, Module, provide } from "@cho/core/di";

@Module(
  imports(OtherModule),
  provide("foo", () => "bar"),
  provide(MyService),
)
class MyModule {
}
