effect-patterns

Structure backend services in TypeScript using Effect by applying composable service and repository patterns that enforce clear separation of concerns. This approach improves consistency and makes testing backend layers significantly easier.

Handle errors in an Effect backend application by using tagged errors and Effect-based workflows to ensure robust failure semantics. This method provides composable logic and reliable error handling across your server-side code.

Implement batch processing and resolvers with Effect to achieve efficient data fetching through batched calls and resolver-style orchestration. This pattern optimizes data loading workflows in TypeScript backend projects.

The Effect library works well for testing repository and service layers by providing practical examples and patterns to validate Effect-based code. Composable logic allows developers to test backend layers in isolation.

Use tagged errors instead of standard exceptions in TypeScript backend patterns to achieve robust failure semantics and composable effects. Standard exceptions often lead to scattered patterns and brittle backend code.
