express-enforce-https v1.0.0

express-enforce-https

Customisable Express middleware to enforce HTTPS on requests.

Summary

This is a really simple piece of middleware. When it detects that a request is using an insecure connection, it sends a response with a status code and message of your choice. You can also customise the handler function for insecure connections to tune express-enforce-https to your needs.

Usage

The main middleware function takes an options object. More on configuration in the Option reference section.

const enforceHttps = require('express-enforce-https')

const options = {
  statusCode: 403
  message: 'Please switch to a HTTPS connection!'
}

app.use(enforceHttps(options))

Option reference

statusCode

The HTTP status code to send when a request is insecure. Defaults to 403.

message

The message to send in response to an insecure request. Can be a string, object or anything supported by Express' res.send(). Defaults to 'Insecure connection detected, please switch to HTTPS.'.

handler

The function to execute when an insecure connection is detected. This function has access to the req, res and next properties from Express, so you can change this any way you like.

Default:

(req, res, next) => {
  res.status(options.statusCode).send(options.message)
}

Note: You lose access to the options object when overriding the handler function.
