No More Sneaky Uploads : How I Made My Node.js App Virus-Free🛡️🦠

#security #node #backend #javascript

So, I’m working on An app, and today it hit me like: What if someone tries to sneak in a virus through a file upload?

But then I found this awesome tool called ClamAV, and its command-line sidekick clamscan, which is like a hero for keeping your app safe from malicious files. Also it's super-easy to integrate in Node.js project.

What I Figured Out

ClamAV is a free, open-source antivirus engine that scans files for viruses, trojans, and other nasty stuff. Think of it as the bouncer at your app’s file upload gate, checking IDs and kicking out troublemakers.(same like security guard of your college😁)

😎Quick Setup Guide-

1). npm i clamscan

2). How to use it in your code-

const NodeClam = require('clamscan');

(async () => {
  const clamscan = await new NodeClam().init();
  const { isInfected, viruses } = await clamscan.isInfected('/path/to/your/file');

  if (isInfected) {
    console.log(`🚨 Uh-oh, infected file! Found: ${viruses}`);
    // Toss the file or block the upload
  } else {
    console.log('🎉 File’s all good!');
  }
})();

that's it . this simple code block can prevent malicious files from being uploaded by users in database
