What is Unit of Work pattern in Go?

It's an interface wrapping atomic ops across repos, hiding tx details like SQL or DynamoDB for clean, testable services.

How to test Go services with Unit of Work?

Mock an in-memory UoW buffering changes—rollback on fn error, commit on nil. Runs blazing fast, proves atomicity sans DB.

Is hexagonal architecture overkill for simple Go apps?

Yes, if one repo per op. Skip for CRUD; use UoW only for cross-repo atomics to avoid needless complexity.

Ditch SQL Txs in Your Go Services: The Unit of Work Fix That Saves Your Architecture

Go devs are wiring sql.Tx straight into services, creating brittle code that fails tests and locks into SQL. A smarter Unit of Work abstraction flips the script—pure domain logic, flawless rollbacks, no leaks.

⚡ Key Takeaways

Passing *sql.Tx into Go services leaks DB details, breaks tests, and vendor-locks you—Unit of Work fixes it cleanly. 𝕏
UoW ports Execute a closure for atomic ops, keeping domain DB-agnostic with in-memory mocks for instant tests. 𝕏
Adopt for multi-repo transactions; skip simple cases—scales to prod without Java's EJB-style bloat. 𝕏
