FIO.WebSockets

NuGet Run Tests License: MIT

WebSockets for FIO. Open connections, send frames, and pattern match on incoming messages as composable effects — connections are scoped and released for you, and failures surface as a typed WsError rather than raw exceptions.

  • Client — WebSocketClient.connectDefault opens a scoped connection
  • Server — WebSocketServer.start / acceptDefault / close to accept clients
  • Typed messages — match on Frame(Text …) / Frame(Binary …) / ConnectionClosed
  • Custom codecs — send and receive typed payloads

Install

dotnet add package FSharp.FIO.WebSockets

Quick Start

open FIO.DSL
open FIO.WebSockets
open FIO.WebSockets.WebSocketExtensions

let client = fio {
    use! ws = WebSocketClient.connectDefault "ws://localhost:8080/ws"
    do! ws.SendString "Hello, server!"
    return! ws.ReceiveString()
}

Server

open FIO.DSL
open FIO.WebSockets

let server = fio {
    let! listener = WebSocketServer.start "http://localhost:8080/ws/"
    let! webSocket = WebSocketServer.acceptDefault listener WebSocketConfig.defaultConfig

    match! webSocket.ReceiveMessage() with
    | Frame(Text text) -> do! webSocket.SendText $"echo: {text}"
    | _ -> do! WebSocketServer.close listener
}

Errors

Operations fail with a typed WsError — ConnectionFailed, SendFailed, ReceiveFailed, MessageTooLarge, TimeoutError, CodecError, Closed, GeneralError — with WsError.fromException / WsError.toException to bridge raw exceptions.
