I'm trying to Fetch a URL (http://localhost) that will return a picture (At this moment, the extension doesn't matter) through HTTP using Node.js.

Front End

let image = await fetch('http://localhost:3031', {
   mode: 'cors',
   method: 'GET'
})

Back End

var http = require('http');
var fs = require('fs');

http.createServer(function (req, res) {
    res.setHeader('Content-Type', 'image/png');
    fs.readFile('image.png', (err, data) => {
        res.write(data, "binary");
        res.end();
    });
}).listen(3031)

I want to take that picture and then display it into the Website.

Im getting the file, NOT THE SRC

node.js http html javascript

Directly in the HTML as:

<img id="loadedimage" src="http://localhost:3031/"/>

Or with fetch, using createObjectURL:

var element = document.getElementById('loadedimage');
var response = await fetch('http://localhost:3031');
var image = await response.blob();
element.src = URL.createObjectURL(image);
