# Reading image files asynchronously and displaying them on the page

I am trying to display images from a folder in my project using the "fs" module with NodeJS. I need to read all images in a directory and run them in a loop for them to be displayed. I was able to do it but I'm not sure if this is the proper or good way to do it.

I inserted my readdir (Reading Files Asynchronously) inside my Homepage route. The images were displayed but I have no one to ask if I did it the proper way.

const express = require('express');
const router = express.Router();
const fs = require('fs');

router.get('/', function(){
if(err) {
throw err;
}
res.render('home', {
files: files
});
});
});

module.exports = router;


• Perhaps you should also provide us the res.render function – konijn Jul 22 at 11:57
• Hi @konijn, res.render function is from express module required on top, you can check here for reference --> expressjs.com/en/api.html#res.render . Thank you! – Vhin Gabuat Jul 22 at 22:44

If anything, the value of './assets/images/' could have been an upfront declared constant, or could have been retrieved from a configuration file.
