Lightning Talks – Andrey Melikhov
summary
A team of ~50 migrated a large Express monolith to Nest and encountered real problems: Nest’s DI binds by class not interface, request-scoped injections had a bug, TypeScript decorators were experimental/incompatible, passport integrations often failed to mount, and class-validator/class-transformer version mismatches blocked upgrades. They resolved this pragmatically by rebuilding small microservices with simple lambda/Express-style handlers and using TypeScript where helpful, which proved more reliable and easier to reason about.
