🌊 First Workflow

A workflow is simply a chain of Actions.

Each Action decides what should run next.

Create two Actions

using WJb;
public sealed class GreetAction : JobAction<string>
{
    public override Task<IActionResult> ExecuteAsync(
        string name, CancellationToken ct)
    {
        Console.WriteLine($"Hello, {name}!");
        return NextAsync<LogAction>($"Greeted {name}");
    }
}
public sealed class LogAction : JobAction<string>
{
    public override Task<IActionResult> ExecuteAsync(
        string message, CancellationToken ct)
    {
        Console.WriteLine($"Log: {message}");
        return CompleteAsync();
    }
}

Register both Actions

var store = new InMemoryStore();
var wjb = WJbBuilder.Create(store, cfg =>
    {
        cfg.AddAction<GreetAction>("greet");
        cfg.AddAction<LogAction>("log");
    })
    .Build(store);

Run the workflow

await wjb.EnqueueAsync("greet", "Alice");
await wjb.ExecuteOnceAsync(); // runs GreetAction
await wjb.ExecuteOnceAsync(); // runs LogAction

What happens

GreetAction
    ↓
LogAction
    ↓
Complete

1. GreetAction prints the greeting. 2. It explicitly schedules LogAction. 3. LogAction writes the log message. 4. The workflow finishes.

Key idea

The next step is decided inside the Action using NextAsync.

Nothing is hidden.
