Bilstrap-iocjs

Bilstrap-iocjs is a IoC(Inversion of Controll) container for your typescript project.

Install

npm install bilstrap-iosjs@latest

This is a simple light weight typescript library that let you to remove your hardcodes dependencies from your ES6 classes. This allow you to manage both singleton and other dependency classes.

class Piston {
  constructor() {}

  public fire() {
    console.log('piston is firing')
  }
}

class Engine {
   constructor(private piston: Piston) {
     console.log('initializing Engine');
     // hardcodes value
     this.piston = new Piston();
   }

   public start() {
     console.log('Stating the engine');
     this.piston.fire();
   }

   public stop() {
     console.log('Stoping the engine');
   }
 }

 class Car {
   constructor(private engine: Engine) {
     // hardcoded values
     this.engine = new Engine(new Piston());
   }

   public start() {
     this.engine.start();
   }

   public getEngine(): Engine {
     return this.engine;
   }
 }

Using bilstrap-iocjs

import { Container } from 'bilstrap-iocjs';

class Piston {
  constructor() {}

  public fire() {
    console.log('piston is firing')
  }
}

class Engine {
   constructor(private piston: Piston) {
     console.log('initializing Engine');
   }

   public start() {
     console.log('Stating the engine');
     this.piston.fire();
   }

   public stop() {
     console.log('Stoping the engine');
   }
 }

 class Car {
   // you dependencies define here
   constructor(private engine: Engine) {}

   public start() {
     this.engine.start();
   }

   public getEngine(): Engine {
     return this.engine;
   }
 }

const container = new Container();
// here you register the class
container.register('piston', Piston, []);
container.register('engine', Engine, ['piston']);
container.register('car', Car, ['engine']);

const BMW: any = container.get('car');
BMW.start();

Singleton classes

// singleton example
container.register('piston', Piston, [], true);

 const BMW: any = container.get('car');
 const BENZ: any = container.get('car');
 BMW.start();
 BENZ.start();

 console.log('is same engine: ', BMW.getEngine() === BENZ.getEngine()) // false
 console.log('is same Piston: ', BMW.getEngine().getPiston() === BENZ.getEngine().getPiston()) // true
