Go stdlib for zero-dependency APIs.

Why

No dependencies, full control, stdlib only. Node.js, Go, and Python are the top 3 backend languages (Stack Overflow 2024).

Go's goroutines handle 100k+ concurrent connections per process; Node's event loop excels at I/O-bound workloads.

When

Use for learning and simple services. Avoid for complex routing.

How

1. go mod init app 2. Define handlers 3. Use http.ServeMux (Go 1.22+) 4. http.ListenAndServe(':8080', mux)

Example

mux := http.NewServeMux() mux.HandleFunc('GET /users', func(w http.ResponseWriter, r *http.Request) { json.NewEncoder(w).Encode(users) })

Common Problems

⚠No middleware — write your own
⚠Routing patterns — Go 1.22+ supports method patterns
⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

✓Use http.Server for timeouts
✓Prefer stdlib for long-term maintenance
✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is Go stdlib HTTP and what projects is it for?

Go stdlib for zero-dependency APIs. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with Go stdlib HTTP in 10 minutes?

Two steps: (1) go mod init app; (2) Define handlers. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with Go stdlib HTTP and how do I avoid it?

The most common pitfall is: No middleware — write your own. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for Go stdlib HTTP?

Best practices for Go stdlib HTTP include: Use http.Server for timeouts; Prefer stdlib for long-term maintenance; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use http.Server for timeouts" — should be set up at project init to avoid costly rework later.

When should I NOT choose Go stdlib HTTP?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Go stdlib HTTP shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
