Create Barrel File

What's a barrel file?

A barrel file is an index.js that exports everything from a directory. This allows us to import named exports directly from that directory instead of referencing the filename.

A simple barrel file located in the src/components directory.

export * from './Container'
export * from './Counter'
export * from './Home'

Now, instead of importing modules based on their specific filenames, we can instead import everything we need in one statement.

A simple usage file located in the src directory.

import { Container, Counter, Home } from './components'

Install

npm install -g create-barrel-file
