Versioning public URLs
Prefer explicit prefixes such as /v1/ for externally visible node-js endpoints. Keep internal-only routes on separate listeners where possible.
Middleware ordering rules
Early chain
Request ids, trace propagation, body size limits, and authentication gates belong early for predictable failures in nodejs services.
Late chain
Serialization, caching headers, and compression belong late—after domain outcomes are known.
Illustrative route table
// illustrative route declarations
routes.register("GET", "/v1/health", handlers.health);
routes.register("POST", "/v1/events", handlers.eventsCreate, { middlewares: [m.authn, m.rateLimit] });Testing routes
Use contract tests that assert status codes, problem payloads, and security headers. Keep tests close to handler modules to reduce drift across node repositories.
Golden tests
Stable snapshots for response shapes where appropriate.
Fuzz inputs
Exercise parsers and validators with hostile inputs in CI.
Operational notes
When rolling out route changes, prefer dual-running old and new paths for a bounded interval, with metrics comparing traffic volumes for each node-js path template.
