Effect.Platform

Platform services for Effect with typed errors and testable interfaces.

HTTP client, file system, and console — all returning Effect with typed errors instead of throwing exceptions.

Install

dotnet add package Effect.Platform --prerelease

Requires the Effect package.

HttpClient

open Eff
open Eff.Platform

let client = Http.fromHttpClient (new HttpClient())

let fetchUser =
    effect {
        let! response = client.Get "https://api.example.com/users/1"
        let! body = Http.getText response
        return body
    }
// Errors are HttpError: RequestFailed | Timeout | ConnectionError

FileSystem

let fs = FileSystem.live

let processFile =
    effect {
        let! content = FileSystem.readAllText "/data/input.txt" fs
        let processed = content.ToUpper()
        do! FileSystem.writeAllText "/data/output.txt" processed fs
    }
// Errors are FileSystemError: FileNotFound | AccessDenied | IOError | ...

Console

Testable console I/O with a built-in test double.

// Production

let tc = Console.testConsole ()
tc.Input.Enqueue("Alice")

let greet =
    effect {
        do! Console.writeLine "Name?" tc.Console
        let! name = Console.readLine tc.Console
        do! Console.writeLine $"Hello, {name.Value}!" tc.Console
