Fable.Actor

Experimental / work in progress.

Fable.Actor is an actor library for F# on .NET, JavaScript, Python and BEAM. Write message loops with actor { }, keep state inside each actor, and communicate through typed messages. BEAM uses native processes; other targets use MailboxProcessor.

open Fable.Actor

let greeter =
    Actor.spawn (fun inbox ->
        let rec loop () = actor {
            let! name = inbox.Receive()
            printfn "Hello, %s!" name
            return! loop ()
        }
        loop ())

Actor.send greeter "World"

Start with Getting started, then follow the documentation guide:

  • One actor API: choose a loop, state handler or command handler.
  • Messaging: state, requests, deadlines and timers.
  • Supervision: linked children and restart policies.
  • Commands: optional state handlers with linked finite work.
  • Lifetimes: optional cooperative shutdown and owned cleanup, using the same builder and NuGet package.
  • Platform notes: portability and runtime limits.
  • Development: build, test and run the examples.

Use messages rather than shared mutable state: on BEAM, actors have separate heaps and captured values are copied.
