This was made for the series of the same name on YouTube
It shows how to use Rust to build a TCP proxy that does Blue/Green deploys of a Fresh/Deno app, which is stored in a Postgres instance (on Amazon RDS for me, but it could be anywhere). The whole thing runs on Control Plane, who sponsored this series (thanks!)
Start the project:
deno task start
This will watch the project directory and restart as necessary.
See also the various tasks in Justfile - the fresh app itself isn't the most interesting part, the Rust code is.
