services.js

import * as services from './module';

const serviceModule = angular.module('app.services', []);

// Automatically register each service.
Object.keys(services).forEach(key => {
  if(!services[key].__service) {
    console.warn(`Service ${key} is missing the @Service decorator.`);
    return;
  }

  const { name } = services[key].__service;
  const defaultName = key.substring(0, 1).toLowerCase() + key.substring(1);

  serviceModule.service(name || defaultName, services[key]);
});

export default serviceModule.name;
