Introduction

• 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

Source

• Angular 18.0.0

Usage

• 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);
console.log(instance.child.output());

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 Currently no longer updated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

Test

• 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

Sync

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