The injector package is a dependecy injection tool built on top of TypeScript decorators for use with Node.JS/TypeScript applications. The original design is for a framework that is soon to come out, this is a prerequisite library.

## Getting Started

### Standard usage.

```typescript

import { Inject, Provide } from '@symbux/injector';

@Provide() // You can optionally give it a name.

export class NumberHelper {

	public multiply(num1: number, num2: number): number {

		return num1 * num2;

	}

}

export class BusinessLogic {

	@Inject() helper!: NumberHelper;

	public main(): void {

		console.log(this.helper.multiply(5, 5));

	}

}

```

### Custom usage.

```typescript

import { Injector, Inject } from '@symbux/injector';

// You can register variables specifically.

Injector.register('my_special_var', 12345);

// You can also resolve them manually.

const mySpecialVar = Injector.resolve('my_special_var');

// You can also inject with a name.

export class BusinessLogic {

	@Inject('my_special_var')

	public specialVariable!: number;

}

```
