javascript - Importing multiple files in react

Question

I am using create-react-app for my react project. It has got webpack configured for importing images. I wish to import multiple images (say 10) from a images folder into a component. The easiest way of doing this would be to add multiple import statement such as -

import Img0 from '../images/0.png';
import Img1 from '../images/1.png';
import Img2 from '../images/2.png';
import Img3 from '../images/3.png';
import Img4 from '../images/4.png';
import Img5 from '../images/5.png';
import Img6 from '../images/6.png';
...

The above code would not be a good choice when we have multiple files to import. Is there a way to add the import statements in a loop? I tried adding for loop but I was unable to modify the variables Img0, Img1 etc. (using ES6 `` didn't work as it converted the variable to a string)

I think maybe a better idea is to use an index file for your images folder.

Supposing you have this structure:

And you need to import all of your images to your HomePage component. You can easily create an index.js file on your images folder, exporting all the images using require, like this:

export const Background = require('./bg/background.jpg');
export const First = require('./photos/first.jpg');
export const Second = require('./photos/second.jpg');
export const LinkedIn = require('./social/linkedin.png');

Then on your component you can import all of them with a single import.

import {
  Background,
  First,
  Second,
  LinkedIn
} from '../../assets/images'

And this would be your final folder structure:

Hope it helps! ;)

If you want to use ES6 named imports:

images/index.js:

import Background from './bg/background.jpg';
import First from './photos/first.jpg';
import Second from './photos/second.jpg';
import LinkedIn from './social/linkedin.png';

export {
  Background,
  First,
  Second,
  LinkedIn
};
