Domains to use

Domains for backend APIs

For API callers (i.e. frontend web/app)

Choose the domain accordingly, prepend it with http or https, and append it with port number and path.

Domains for frontend website (dashboard)

https://dashboard.diaper-project.cfcom

(If you visit via http:// (without secure) , you'll be automatically redirected to https:// (with secure))

Note: More details about this, go to the doc "Deploy React on AWS"

SSL Certificate for https (Skip this as long as you know what is SSL and certs)

The free SSL cert from Let's Encrypt is used for this purpose.

Let's Encrypt website (no need to visit for this purpose, though): https://letsencrypt.org/

Where do we need to use SSL certs?

SSL certs are required wherever there is a https and domain (Mind the s at the end)

Please refer to the two docs about how to deploy them to find details of using SSL certs.
