Is it possible to import a group of images as an array? (create-react-app project)

问题

Is it possible to import a group of images as an array? (create-react-app project) like written below but as a single-line?

import Hat1 from '../../assets/img/accesories/hats/hat1.png';
import Hat2 from '../../assets/img/accesories/hats/hat2.png';
import Hat3 from '../../assets/img/accesories/hats/hat3.png';
import Hat4 from '../../assets/img/accesories/hats/hat4.png';
import Hat5 from '../../assets/img/accesories/hats/hat5.png';
import Hat6 from '../../assets/img/accesories/hats/hat6.png';

const hatsArr = [
    Hat1,
    Hat2,
    Hat3,
    Hat4,
    Hat5,
    Hat6
];

回答1:

You can't directly import them as an array but you can use a file dedicated to these imports :

images.js :

import Hat1 from '../../assets/img/accesories/hats/hat1.png';
import Hat2 from '../../assets/img/accesories/hats/hat2.png';
import Hat3 from '../../assets/img/accesories/hats/hat3.png';
import Hat4 from '../../assets/img/accesories/hats/hat4.png';
import Hat5 from '../../assets/img/accesories/hats/hat5.png';
import Hat6 from '../../assets/img/accesories/hats/hat6.png';

export default [
    Hat1,
    Hat2,
    Hat3,
    Hat4,
    Hat5,
    Hat6
];

Then import this array in one line in other files :

import hatsArr from './images';

Edit : I think you can do some tricky stuff in webpack.config.js to achieve this one line import but can't help on that.

You can write a separate file to export those images like below:

var AppData = {


adata: {
    "initialdata":[
      {
      "text":"",
      "image":"images/slider1.png"
      },
      {
      "text":"",
      "image":"images/slider2.png"
      },
      {
      "text":"",
      "image":"images/slider3.png"
      }
    ]
  }
}
export default AppData;

and import it in your component like below:

import AppData from './AppData';

class App extends Component {
  constructor() {
    super();
    this.state = AppData.adata;
  }

  render() {
    return (
      <ul className="slider">
        {this.state.initialdata.map(function(item,index) {
            return (
                <li key={index}>
                 <img className="sliderImage" src={`./${item.image}.png`} role="presentation" alt="image"/>
                </li>       
            )
        },this)}
      </ul>
    );
  }
}

Hope this would help and working demo by exporting,importing like this demo

I have a hybrid of a solution of what has been mentioned here

import Hat1 from '../../assets/img/accesories/hats/hat1.png';
import Hat2 from '../../assets/img/accesories/hats/hat2.png';
import Hat3 from '../../assets/img/accesories/hats/hat3.png';
import Hat4 from '../../assets/img/accesories/hats/hat4.png';
import Hat5 from '../../assets/img/accesories/hats/hat5.png';
import Hat6 from '../../assets/img/accesories/hats/hat6.png';

export const hatsArr = [
    Hat1,
    Hat2,
    Hat3,
    Hat4,
    Hat5,
    Hat6
];

... your logic goes here ...

Notice that all you have to do is add export in front of you const.

This way you can have your images AND your logic in ONE file at the cost of just one keyword.
