Express + CloudFlare with SSL

I have an express app freshly created using

express appName
.
I've changed the port to 443.
The domain is under CloudFlare's proxy with SSL enabled.
When I go to the website though, I get the CloudFlare page
Web server is down
instead of seeing the express index page.

How can I make Express work with CloudFlare's SSL?

Answer

There are two options:

  • You need to alter your app such that it is able to accept HTTPS connections instead of HTTP. You can do this by using the HTTPS library instead of HTTP.
  • You can switch to Flexible SSL instead of Full, but this is not recommended for a lot of applications as it means the connection from Cloudflare's Edge to your Origin is unencrypted.
