Handling Errors in TypeScript with Custom Error Classes and Effect Library

class ApplicationError extends Data.TaggedError(`ApplicationError`)<{ cause?: unknown }> {}

const someOtherFunction = async () => {
  return Promise.reject(new Error('This is an error'))
}

export const handler = () => Effect.gen(function* ($) {
  const eff = Effect.tryPromise(() => someOtherFunction())
    .pipe(
      Effect.mapError(({ error }) => new ApplicationError({ cause: error }))
    )

  yield* $(eff)
}).pipe(runPromise)
