📧 Send Email → Log → Done

A complete sequential workflow example.

send-email
    ↓
log
    ↓
Complete

1. Input Models

public sealed class EmailInput
{
    public string To { get; init; } = string.Empty;
    public string Subject { get; init; } = string.Empty;
    public string Body { get; init; } = string.Empty;
}
public sealed class LogInput
{
    public string Message { get; init; } = string.Empty;
}

2. Actions

[ActionName("send-email")]
public sealed class SendEmailAction : JobAction<EmailInput>
{
    public override async Task<IActionResult> ExecuteAsync(
        EmailInput input, CancellationToken ct)
    {
        // Simulate sending email
        Console.WriteLine($"Sending email to {input.To}: {input.Subject}");
return await NextAsync<LogAction>(
            new LogInput
            {
                Message = $"Email sent to {input.To}"
            });
    }
}
[ActionName("log")]
public sealed class LogAction : JobAction<LogInput>
{
    public override async Task<IActionResult> ExecuteAsync(
        LogInput input, CancellationToken ct)
    {
        Console.WriteLine($"LOG: {input.Message}");
return await CompleteAsync();
    }
}

3. Registration

var wjb = WJbBuilder.Create(store, cfg =>
{
    cfg.AddAction<SendEmailAction>();
    cfg.AddAction<LogAction>();
});

4. Starting the Workflow

await wjb.EnqueueAsync("send-email",
    new EmailInput
    {
        To = "user@example.com",
        Subject = "Welcome",
        Body = "Thank you for joining us!"
    });

5. Execution Result

Sending email to user@example.com: Welcome
LOG: Email sent to user@example.com

Job status becomes Completed.

Key Point

This is the classic sequential pattern:

• First action does the work and schedules the next step
• Second action finishes the workflow with Complete
