@dmitriyzverev/locator

Simple implementation of Service Locator pattern with singletons and lazy loading

---

Usage

1. Install dependencies:

   npm i -SE @dmitriyzverev/locator

2. Create locator and define your services inside:

   import {createLocator} from '@dmitriyzverev/locator';
   const locator = createLocator({
       services: {
           get user() {
               return {
                   name: 'Bob',
               };
           },
           get helloMessage() {
               return `Hello, ${locator.user.name}!`;
           },
       },
   });

   Now you can use any service defined in locator:

   console.log(locator.helloMessage); // Hello, Bob!

   By default, each service is a singleton. It will be created only once, and only if requested. If you need to create a new service instance for each service request, disable the service singleton in the singletons property:

   import {createLocator} from '@dmitriyzverev/locator';
   const locator = createLocator({
       services: {
           get user() {
               return {
                   name: 'Bob',
               };
           },
       },
       singletons: {
           user: false,
       },
   });
   console.log(locator.user === locator.user); // false
