Three microservices, two incompatible auth models, one public endpoint, and a Go gateway that turned into a pile of strings.HasPrefix conditionals. Here's the rewrite, in Go + TypeScript, and why it ended up sandboxed across two runtimes.
The article today might be a little boring depending on how much you're into systems and distributed architecture. And if you're already thinking, "Great, another API gateway," I can't really blame you.
But bear with me for a bit: Conduit isn't just another request-forwarding proxy. Along the way, we'll dive into programmable gateways, sandboxed runtimes, Unix sockets, and some of the engineering decisions that made building it surprisingly fun.
TL;DR
Built a small Go API gateway in front of three services with two different auth schemes (custom HMAC sessions, and JWT).
