Reviewer scorecard
“Typed errors and dependency injection for TypeScript done right. The platform modules (HTTP, Schema, SQL) are production-grade.”
“Revived by the Nx team and better than ever. The standard for publishing multiple npm packages from a monorepo.”
“Steep learning curve and the functional programming style isn't for everyone. The benefits are real but the adoption cost is high.”
“Was nearly dead, but Nx's stewardship brought it back. For npm publishing workflows, it's still the go-to.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
“Nx and Turborepo are the future of monorepo tooling. Lerna is a legacy tool that works but isn't innovating.”
