如何显示本地 Json 文件中的数据（图像）

Question

I am new to React and am trying to figure out how to parse this data file to create a number of divs with the images as backgrounds and the text overlayed. Right now, I am having a hard time with even getting any data to display on the page without editing the json file to have export const = images instead of what it is currently. The images listed in my example code are different than actual. Any help is greatly appreciated! Thanks!

images.json

{
  "images": [
    {
      "id": "1425ac9e-5718-4e2e-af43-132dcf58246b",
      "description": "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.",

      "subtitle": "sit amet"
    },

  ]
}

thumbs.js

import React from 'react';
import { images } from '../../data/images.json';

export const Thumbs = () => {
  return (
    <>
    <div className="thumb-container">
      {images.map((data, key) => {
        reutrn (
          <div key={key}>
            {data.thumb}
          </div>
        );
      })}
    </div>
    </>
  );
};

I also have a file that renders a.Thanks for reading!

You have return mispelled. That's the only error I can find in your code, I ran it in a brand new create-react-app app and it worked just fine. There could be an issue if you're not using a recent version of Webpack, but it would have to be a pretty old version to not have built in json loading. And here's my modified code, which is just showing the images rather than their URLs:

export const Thumbs = () => (
  <div className="thumb-container">
    {images.map((img, i) => <img src={img.thumb} key={i} />)}
  </div>
)
