Using nginx in front of my app

[Decor]

Hi,

I would like to not bother with the networking side of my project.
Hence I will use nginx to receive https/websocket requests and serve static
html (vuejs) files.

But, sometimes, clients will call my API for more complex actions
(database...) and I would like nginx to be a proxy to simplify my
application. 

client sends encrypted websocket 
> nginx receive it and decrypts it 
> nginx transfers the http content using UDP (for simplicity) to my local c
socket application 
> my app does what it does best and sends back the response to nginx 
> nginx sends back the valid encrypted packet to the client

So I need nginx as a https proxy but switching to UDP protocol and
remembering how to answer the client after getting the response from my
app.

How may I do that?

Thanks
