I want my the /image of my app to return a random image, how can I do that?

app.js:

const app = express();



app.get('/image', async (req, res) => {

  const url = 'https://example.com/images/test.jpg';

  res.send(/**/);  // How do I send the image binary data from the url?

});

index.html

In HTML, this image actually shows the content of the image https://example.com/images/test.jpg

<img src=https://my-app.com/image />

We have the same problem, and this is my solution for this using request package, so you have to yarn add request or npm i request first.
your code should be like this

const request = require('request');

const express = require('express');

const app = express();



app.get('/image', async (req, res) => {

  const url = 'https://example.com/images/test.jpg';



  request({

    url: url,

    encoding: null

  }, 

  (err, resp, buffer) => {

    if (!err && resp.statusCode === 200){

      res.set("Content-Type", "image/jpeg");

      res.send(resp.body);

    }

  });

});
