Andurel v2.0.0-alpha is a major release of a Go web framework featuring independently versioned modules, Fx composition roots, pgx/v5 persistence, Inertia v3 UI support, and new CLI commands. The release requires Go 1.27.1 and introduces architectural changes including application-owned Inertia documents and a new configuration system.
Optimistic UI—showing changes immediately before server confirmation—requires fundamental architectural changes beyond a simple UX tweak. Implementing it in Rulrmail exposed cascading challenges: handling overlapping requests, synchronizing feedback, managing premature undo clicks, preventing race conditions in shared state, and resolving database locking issues.
