# 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`

```ts

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 Currently no longer updated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`
