Depender

A simple javascript realisation of Dependency Injection pattern.

Example of DI

import { injectable } from '@depender/core/injectable';
import { Container } from '@depender/core/container';

@injectable() // <-- Add injectable decorator
class DependencyOne { 
    print() {
        console.log(123);
    }
}

@injectable() //  <-- Add injectable decorator
class Application {  
    constructor(
        public dependencyOne: DependencyOne, // <-- instance will be created by Depender
    ) {}

    callDependency() {
        this.dependencyOne.print(); // <-- Call child instance created by Depender
    }
}

const applicationInstance: Application = Container.inject({ class: Application });
applicationInstance.callDependency() // <-- Prints 123
