const moduleMap = new Map();

async function loadModule(name) {

  }
  
  const module = await Promise.resolve({
    default: () => `Module ${name} loaded`,
    version: '1.0.0'
  });
  
  moduleMap.set(name, module);
  return module;

loadModule('auth').then(m => console.log(m.default()));
loadModule('auth').then(m => console.log(m.version));
loadModule('db').then(m => console.log(m.default()));
