Es6 exporting/importing in index file

Clarity and accessibility with named and default exports

Named exports allow for explicit exports, enhancing readability and maintainability when your module provides multiple entities. On the other hand, default exports are suitable when we have a single main export in our module - it's like the crown jewel 👑, it stands alone.

The art of exports organization (or the 'DRY' principle)

Avoid repetitive export declarations to prevent confusion (and carpal tunnel syndrome 😉). Consider an index.js as a housekeeper, consolidating and organizing exports for a cleaner API surface.

// Below exports: We are family! 🎵
export { default as User } from './User';
export { Login, Logout } from './Authentication';


In the consumer file:

// Single-line import: 'Simplicity is the ultimate sophistication' - DaVinci 🎨
import { User, Login, Logout } from './components';


Peak into the future with ES8

Although history belongs to ES6, keep an eye on future proposals. Always chase the next big wave in JavaScript 🌊 - regular GitHub munching can keep you well-fed with all the insights you need!

Serve multiple exports efficiently

We all love smart folder structures. Consider bundling related files within the same directory where index.js whips up a buffet of centralized exports. Hence, creating a monolith import 🗿 elsewhere becomes a breeze!

// Centralize exports in folder index.js
// Home is where the art is 🏡 🎲 
export * from './Button';
export * from './TextInput';


Now, extract what you need using a cleaner import:

// Kitchen is ready, order up! 🍽️
import { Button, TextInput } from '../components/shared';


Having the cake and eating it too: mixed export types

Sometimes functions can't be typecasted into simply default or named exports. Fret not, you can export them side by side:

// Giving you the best of both worlds 🌗
export { default as DefaultComponent, namedExport1, namedExport2 } from './MyComponent';


This approach brings uniformity and predictability into your imports.

The long game: Balance ES6 with new tech

ES6 with its modular aspects made our lives whole lot simpler. But, sometimes you've got to spread your wings and look for innovations beyond ES6. Keep an eye on Webpack Module Federation and dynamic imports to stay ahead of the curve!
