I had to use new Reference('service.animal') in the index.js file. It worked ! But still not sure if that the correct?

Yml i have tried the yml file as well to understand the configuration. No luck

@venkataramkishore can you please add your code here with a simple example of what you are doing?

[venkataramkishore]

Hi @zazoomauro , I have attached my code as requested. Please do npm install first and npm start ditest.zip

Thank you for your help.

[zazoomauro]

@venkataramkishore Instead of uploading ditest.zip file I would like to see your code here like:

hello = 'bye bye'
function() {...}

[venkataramkishore]

Ok, The following is the code

# dependency-config.yml
services:
  service.animal:
    class: 'src/Animal'
  service.tiger:
    class: 'src/Tiger'
    arguments: ['@service.animal']

# index.js
const ContainerBuilder = require('node-dependency-injection').ContainerBuilder;
const YamlFileLoader = require('node-dependency-injection').YamlFileLoader;

let container = new ContainerBuilder()
let ymlFileLoader = new YamlFileLoader(container);

ymlFileLoader.load('./dependency-config.yml');
const mailer = container.get('service.tiger');
mailer.printMessage('Hello Node ..!');

# src/Animal.js
class Animal {
    constructor() {}

    print(msg) {
        console.log('Classone print message', msg);
    }
}
module.exports = Animal;

# src/Tiger.js
class Tiger {

    _animal;
    constructor(animal) {
        console.log('animal instance ', animal);
        this._animal = animal;
    }

    printMessage(message) {
        this._animal.print(message);
    }
}
module.exports = Tiger;

Finally with

# package.json
{
  "name": "ditest",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "node-dependency-injection": "^2.6.8"
  }
}

After

npm install && npm start
