⏳ nr-contrib-async-loader

Async Loader is a custom Node-RED node that simulates asynchronous processing. It dynamically displays a progress bar in the node's status area and forwards the message only after the simulated task is completed.

✨ Features

• Async Process Simulation: Perfectly mimics long-running tasks (like database queries or API calls).
• Dynamic Progress Status: Real-time visual feedback ([████▒▒▒▒] 40%) right inside the Node-RED editor.
• Seamless Integration: Fully compatible with Node-RED v3+.
• Lightweight & Fast: Uses native JavaScript setInterval without heavy external dependencies.

📦 Installation

Run the following command in your Node-RED user directory (typically ~/.node-red):

npm install nr-contrib-async-loader

(Note for development: You can also use npm link to install this node locally).

🚀 Usage Example

1. Add the async-loader node to your flow.
2. Configure the duration in milliseconds (e.g., 3000 for 3 seconds) by double-clicking the node.
3. Connect an inject node to its input, and a debug node to its output.
4. Deploy your flow.
5. Send a message using the inject node to test and watch the animated status!
