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.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“The API design is thoughtful. Integrates well with existing stacks.”
