Using dependency injection in nodejs environment


  • Angular dependency injection standalone version
  • The usage method is completely consistent with Angular's dependency injection
  • No transformer required
  • 0 dependencies
  • Remove Decorator > @Injectable()=>static injectOptions={} > @Inject() xx=>xx=inject() > @Optional()=>xx=inject(token,{optional:true})
  • JS/TS Support


  • Angular 17.3.6


  • npm i static-injector
  • Create a first level dependency injector with Injector.create
import { Injector, inject } from 'static-injector';

class Main {
  child = inject(Child);
class Child {
  output() {
    return 'hello world';
let injector = Injector.create({ providers: [Main, Child] });
const instance = injector.get(Main);
Enter fullscreen mode Exit fullscreen mode

Different from injection-js

  • injection-js belongs to dynamic dependency injection and is a version used before Angular5. Currently no longer updated
  • The two are basically interchangeable (the details need to be adjusted)

  • Support the use of inject during construction

No Decorator

  • The original use of @Injectable() to pass parameters has been changed to static injectOptions={}. If there are no parameters, there is no need to set them
  • Originally, @Optional, @SkipSelf, @Self, please use the second pass parameter of inject instead


  • Partially conducted unit testing to ensure that most functions are functioning properly
  • Because most of the code itself is extracted from Angular, stability is definitely guaranteed


  • Currently, the synchronization logic has been refactored and modified using @code-recycle/cli to ensure consistency with the official version of angular
