📦 WJb.Demo (WASM)

Lightweight demo application showcasing WJb background job engine running in a Blazor WebAssembly (WASM) environment.

---

🚀 Overview

WJb.Demo (WASM) demonstrates how to:

• Execute background jobs in a client-side environment
• Track job lifecycle and progress in real time
• Use clean, decoupled job actions
• Chain and configure actions
• Handle success, failure, and cancellation scenarios

---

🧩 Features

• ✅ Job dashboard with live updates
• ✅ Multiple action types:
  • Hello Action
  • Configured Action
  • Progress Action
  • Chained Actions
• ✅ Progress tracking (0–100%)
• ✅ Status handling:
  • Completed
  • Failed
• ✅ Message output per job
• ✅ Job cleanup support

---

🖥️ UI Overview

The demo UI includes:

• Sidebar navigation
  • Dashboard
  • Action samples
• Active Jobs table
  • ID
  • Status
  • Progress bar
  • Message
  • Remove action

Example states:

• Completed jobs with full progress
• Failed jobs with partial progress
• Informational messages for each job

⚙️ How It Works

WJb separates concerns into:

• Execution – runs actions
• Storage – tracks job state
• Hosting – coordinates lifecycle

In this demo:

• Jobs are triggered from UI
• Execution happens in WASM runtime
• Progress updates are reflected immediately

---

▶️ Run Locally

git clone https://github.com/UkrGuru/WJb.Demo
cd WJb.Demo
dotnet run

Then open:

https://localhost:7268

🧪 Example Scenarios

• Run simple job (Hello Action)
• Execute configured job (SMTP simulation)
• Track progress over time
• Trigger chained jobs
• Observe failure handling

📌 Notes

• This is a demo application intended for showcasing WJb capabilities.
• Behavior and APIs may evolve.
• Some features may be simplified for demonstration purposes.
