configureContainer.js

import { createContainer, asClass, asFunction } from 'awilix'
import makeTodosService from './todosService'
import TodosRepository from './todosRepository'

export default function configureContainer () {
  const container = createContainer()
  
  // Ordering does not matter.
  container.register({
    // Notice the scoped() at the end - this signals
    // Awilix that we are gonna want a new instance per "scope"
    todosService: asFunction(makeTodosService).scoped(),
    // We only want a single instance of this
    // for the apps lifetime (it does not deal with user context),
    // so we can reuse it!
    todosRepository: asClass(TodosRepository).singleton()
  })
  
  return container
}
