Express Force Secure

Forces the Express application to be served over a secure connection.

Aborts when it does not detect a secure connection instead of upgrading the request.

Installation

npm install --save express-force-secure

Usage

app.use(require('express-force-secure')())

Error handling

The middleware will return a 426 — Upgrade required error, you can check for this error using the code property.

// error middleware
app.use((err, req, res, next) => {
	if (err.code === 426) {
		// ...
	}
})

Proxy

If the Express application sits behind a proxy, you must manually trust the proxy by setting trust proxy.

app.set('trust proxy', true)

This will allow the middleware to pick up the X-Forwarded-Proto header.

Make sure you correctly set the X-Forwarded-Proto header in your Proxy.

Nginx

location / {
	proxy_pass http://127.0.0.1:3000/;
	proxy_set_header Host $host;
	proxy_set_header X-Real-IP $remote_addr;
	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_set_header X-Forwarded-Proto $scheme;
}
