Question about Do notation
Basically, I have some experiences with FP-TS and I playing around with Effect-TS, below is the code I playing with Do notation
But the typescript complaint
I also not get any chance by wrap
I even do the simplest thing in this context:
It still error
Please help
const program = pipe(
Effect.Do,
// error next line
Effect.bind('connIdToSocket', () => Ref.make(Map.empty<string, SocketStream>())),
Effect.bind('clientIdToConnId', () => Ref.make(Map.empty<string, string[]>())),
Effect.flatMap(({connIdToSocket, clientIdToConnId}) => {
// do something with connIdToSocket and clientIdToConnId
})
)const program = pipe(
Effect.Do,
// error next line
Effect.bind('connIdToSocket', () => Ref.make(Map.empty<string, SocketStream>())),
Effect.bind('clientIdToConnId', () => Ref.make(Map.empty<string, string[]>())),
Effect.flatMap(({connIdToSocket, clientIdToConnId}) => {
// do something with connIdToSocket and clientIdToConnId
})
)But the typescript complaint
