How do I start hexagonal architecture in Go?

Port your domain: extract logic to package, define repo interfaces. Stub for tests. Wire adapters outside.

Why are my Go tests so slow?

Tangled deps—DB in units. Hexagonal isolates; tests fly.

Nope. Tiny ports? Hand-stubs beat reflection every time.

Sick of Go tests that chug like old hardware? Hexagonal architecture flips the script—pure domain logic tests in a blink, no databases required.

Ditch Docker in units—use stubs and rare integrations for a natural test pyramid. 𝕏
No need for mocking frameworks; simple hand-written doubles suffice. 𝕏
