req.protocol is not picking up "https" for my secure link. It always pics "http" . For creating my baseURL am using this. any solutions please?

That's happening most probably because there is a proxy in between. In my case I am using Heroku.

If that's the case, you need to add app.enable('trust proxy'); to your express app.

Without enabling that, req.protocol returned http. After that change I got https.

You can also use req.secure to get true or false depending on if your app is secured by https or not.
