As a script dependency, I recommend using wp-api-request
instead of wp-api
unless you need the full wp-api + backbone + underscore to be loaded and ready for use otherwise you're just loading a bunch of stuff you do need.
Using wp-api-request
you still get access to wpApiSettings.root
and wpApiSettings.nonce
which is all you need to send a REST request.

What if I'm sending post data from another website to WP data backend?
