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 17.3.6
Usage
npm i static-injector
Create a first level dependency injector with Injector.create
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 Currently no longer updated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
