AWS ELB with Node.js and WebSockets

This assumes that:

• You are using Nginx.
• You want to accept incoming connections on port 80.
• Your Node.js app is listening on port 3000.
• You want to be able to connect to your Node.js instance directly as well as via the load balancer.

Top-level await is a footgun 👣🔫

Follow-ups:

• Why imperative imports are slower than declarative imports
• Dynamic module loading done right
• Non-deterministic module ordering is an even bigger footgun

As the creator of Rollup I often get cc'd on discussions about JavaScript modules and their semantics. Recently I've found myself in various conversations about top-level await.
