I have created a web-app using vue.js and firebase as my back-end. and I want to use the PayPal subscription system, but I couldn’t integrate the paypal-rest-sdk with it.
now I have to create a node.js app besides handle that.
but I want available only to my web-app, hosted in the same droplet with Nginx.
can I do that?

Yes this sould be ok, you just need to make sure that the port that your express application is closed via your firewall so that nobody could access it. Then you could use Nginx as a reverse proxy to control the access to that service.
