The goal is a design that is small enough to read in one sitting but realistic enough to deploy. We favor explicit SQL over an ORM so that the data model stays transparent, and we lean on Fastify's schema validation and plugin system to keep the codebase organized.

Go does not validate XML against XSD out of the box, and no mature pure-Go validator has emerged to change that. The practical, production-proven path is a cgo binding over libxml2.

SSL/TLS certificates are the backbone of secure communication on the modern web.

Node.js gives you everything needed to manage TLS certificates end to end.

Go is one of the very few languages that ships a complete, production-grade TLS stack in its standard library.

Node.js gives you everything needed to sign files properly: modern algorithms through a stable built-in module, streaming digests for artifacts of any size, and a standards-based alternative when code must run in more than one runtime.

Go's standard library gives you everything required to sign files correctly with no external dependencies.

Node.js is often described in a single, slightly misleading sentence: "it is single-threaded." That statement is true of the JavaScript code you write, but it hides a much richer reality.

Python gives you three concurrency models because there is no single right answer.

Concurrency is one of the defining features of the Go programming language.
