Short ppt and a simple demo app used during guest lecture to PES students on 2020-11-20.
run npm install on client and server, use npm start in respective folders.
I used marp to convert markdown to presentation, create-react-app for creating the client for the demo app.
I used Expose during the talk to create a tunnel to my machine. The setup is a bit complex, but this is the best one afaik.
PSA: The explanation I gave to the question asked right at the end wasn't quite right/that straightforward. Have a look at https://stackoverflow.com/questions/8107856/how-to-determine-a-users-ip-address-in-node
Thanks for tuning in.
