Reviewer scorecard
“Typed errors and dependency injection for TypeScript done right. The platform modules (HTTP, Schema, SQL) are production-grade.”
“Steep learning curve and the functional programming style isn't for everyone. The benefits are real but the adoption cost is high.”
“This fills a real gap in the ecosystem. Worth adopting early.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
“The team ships fast and responds to feedback. Good sign.”
