Information Security with HelmetJS - Install and Require Helmet

JavaScript
1

Tell us what’s happening:

TypeError: Router.use() requires a middleware function but got a Object

What happened thus far:

I’ve cloned the github repo to my machine and I’ve ran npm i to install dependencies. (Here I ran into a slight issue, since npm found vulnerabilities in old express packages and didn’t want to install it, so I’ve force-installed it with npm install express@4.14.0)

Without adding additional code I’ve encountered the above-mentioned type-error. With many hours of research I cannot find how to resolve the issue.

What I’ve tried so far:

  • replacing const app = express() to const app = express.Router()
  • moving the module.exports = app
  • messing with the server.js code

I’ve just moved the module.exports = app in server.js before the app.use declaration and, magically, it works?

It says: Your app is listening on port 3000
