I built a VS Code extension that broadcasts UDP messages on task completion 🚀

I often compile firmware, embedded projects, or code that triggers hardware tests.

But I always wished I had a physical indicator — like an RGB LED or display — to show when a build finishes successfully or fails.

So I made a small but useful VS Code extension:

👉 notifybuildresult

https://github.com/sdrshnptl/notifybuildresult

🔧 What it does

This extension broadcasts a UDP message whenever a VS Code task completes.

You can trigger anything that listens on your network:

RGB LEDs (ESP32, Arduino)
Desktop indicators
IoT devices
Dashboards
Lab automation
Raspberry Pi scripts
Home automation nodes

Example use case:

💡 Build succeeded → LED turns green

❌ Build failed → LED turns red

📡 How it works

When a task finishes, the extension sends a JSON payload like:


json
{
  "task": "build",
  "status": "success"
}
