# 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 19.2.0

# Usage

- Create a first level dependency injector with `createRootInjector`

```ts
import {
  Injector,
  inject,
  // root
  createRootInjector,
  // child
  createInjector,
} from 'static-injector';

class Main {
  child = inject(Child);
}
class Child {
  output() {
    return 'hello world';
  }
}
let injector = createRootInjector({ providers: [Main, Child] });
const instance = injector.get(Main);
console.log(instance.child.output());
```

# 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

# reactivity

- support `signal`,`effect`,`resource`,`linkedSignal`,`computed`

# 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`
