effect-ts

Effect-TS is a functional TypeScript library providing typed effects, structured concurrency, and a robust runtime.

Use the Cache module: @effect/schema generates JSON Schema Draft-07 (not 2020-12): Effect has native OpenTelemetry integration: - Expected Errors (Failures) - Typed in E channel, must be handled - Unexpected Errors (Defects) - Runtime bugs, captured but not typed - Effect Documentation - Effect GitHub - @effect/schema JSON Schema - @effect/opentelemetry
