Trax.StateMachine

Build NuGet codecov License: MIT Docs

Part of Trax .NET: business logic you can call, schedule, or serve as an API, with every run recorded in your Postgres. Docs · Getting started · Repository

Trax.StateMachine is the portable state-machine engine: a multi-step flow's state as language-neutral JSON, with each event's guard, reducer and caller rule declared as data. Trax.StateMachine.Persistence stores each instance per user, runs a machine's one irreversible effect exactly once, and lets a state invoke a train. @traxsharp/state-machine on npm runs the same machine in the browser.

Install

dotnet add package Trax.StateMachine.Persistence
dotnet add package Trax.StateMachine.Testing   # in a test project

Example

From Author and serve a machine:

[TraxMachine]
public sealed class CheckoutMachine : Machine<CheckoutState, CheckoutTrigger>
{
    protected override void Configure(IMachineBuilder<CheckoutState, CheckoutTrigger> m)
    {
        m.Id("checkout").Version(1) /* start, rules on Get, Watch and Discard */;

        m.In(CheckoutState.Review)
            .Context<CartContext>()
            .On(CheckoutTrigger.Pay)
            .AnyAuthenticated()
            .WithInput<PayInput>()
            .RunsOnce<ICharge>("checkout:charge")
            .To(CheckoutState.Paid);

        m.In(CheckoutState.Paid).Context<PaidContext>().Committed();
    }
}

builder.Services.AddTrax(trax =>
    trax.AddEffects(effects => effects.UsePostgres(connectionString))
        .AddStateMachines(typeof(CheckoutMachine).Assembly)
        .AddMediator(typeof(CheckoutMachine).Assembly));

The server runs ICharge once per send and fires Pay with its receipt. A client never fires Pay itself.

Where this fits

Trax is split into layers, one folder of this repository each. Take the ones you need; the trains you wrote do not change. You are here: Trax.StateMachine.

Folder What it adds
Trax.Core Trains, junctions and the chain, with no database and no DI container
Trax.Effect A recorded run for every execution (Postgres, SQLite or in memory), DI, effect providers
Trax.StateMachine State machines a page drives and the server applies, in C# and TypeScript, held to one conformance kit
Trax.Mediator The train bus: run a train by handing over its input, with every chain checked at startup
Trax.Scheduler Cron and interval schedules, retries, dead letters, and workers on other machines or in Lambda
Trax.Api GraphQL generated from your trains, with authentication, audit and typed clients, and the operations console your host serves
Trax.Cli The trax tool: scaffold a hub and trains from an OpenAPI or GraphQL schema, and state-machine codegen
Trax.Samples Complete sample apps, and the trax-api, trax-scheduler and trax-hub templates
