Use index.js to import multiple image assets in React

Question

I have been using a pattern of collecting component files for export with index.js files placed in directories, for example:

// index.js file in /components directory
export { Splash } from './Splash'
export { Portfolio } from './Porfolio'
export { Contact } from './Contact'

In Layout.js (located in root directory) I can neatly import with one call:

import { Splash, Portfolio, Contact } from '.'

I use this pattern a lot as I structure components across directories and sub-directories.

My specific question is to ask if there is any way to extend this pattern to image assets collected in src/assets/img? Can I place an index.js file in my images directory and to be able to call groups of images to a component?

//index.js in /src/assets/img directory
export { Img01 } from './img-01.png'
export { Img02 } from './img-02.jpg'
export { Img03 } from './img-03.svg'

//Call in Component.js
import { Img01, Img02, Img03 } from '../assets/img'

I think this should be achievable, but I can't figure out the correct syntax or modifications required to this pattern. Any code samples or recommendations for better practices are appreciated. Thanks in advance!

Answer 1

To export default components do it like this:

export { default as Splash } from './Splash'
export { default as Portfolio } from './Porfolio'
export { default as Contact } from './Contact'

// you dont need to include the 'index' on the route, just do './' if you 
// are in the same directory, but your export file must be named index.js
import { Splash, Portfolio, Contact } from './';

To export files: images, css, .svg etc, just include the file extension:

export { default as Img01 } from './img-01.png'
export { default as Img02 } from './img-02.jpg'
export { default as Img03 } from './img-03.svg'

//Call in Component.js

import { Img01, Img02, Img03 } from '../assets/img'

if you are using webpack take a look at this require. You can use require to import a file like the example below:

tree directory

-images 
  |_index.js
  |_notification.png
  |_logo.png
-pages
  |-home.js

images/index.js

export const notification = require('./notification.png')
export const logo = require('./logo.png')

pages/home.js

import { notification } from '../images/'
<img src={notification} />

i hope i helped you
