Native Tauri App Conversion

Overview

Your AxeOS Live! app has been successfully converted from a hybrid Next.js server-based app to a truly native desktop application using Tauri commands in Rust. This eliminates the need for Next.js API routes and makes it a standalone, statically-built desktop app.

What Changed

Before (Hybrid Approach)

Next.js ran as a server inside Tauri
API routes (/api/miner/[ip]) proxied requests to miners
Required Next.js server to be running
Larger bundle size
Slower startup

After (Native Approach)

✅ Next.js builds to static HTML/CSS/JS
✅ Tauri Rust commands handle all network requests
✅ No server required - pure desktop app
✅ Smaller bundle size
✅ Faster startup and performance
✅ True cross-platform builds

Changes Made

1. Rust Backend (Tauri Commands)

File: `src-tauri/Cargo.toml`

Added dependencies:

reqwest = { version = "0.12", features = ["json"] }
tokio = { version = "1", features = ["full"] }

File: `src-tauri/src/lib.rs`

Created 3 Tauri commands:

get_miner_data - Fetches miner information

Tries multiple API paths: /api/system/info, /api/system, /api/swarm/info
10-second timeout
Returns JSON data or error

restart_miner - Restarts a miner

POST to /api/system/restart
Returns success or error

update_miner_settings - Updates frequency and voltage

PATCH to /api/system with { frequency, coreVoltage }
Returns success or error

File: `src-tauri/capabilities/default.json`

Added permissions:

"allow-get-miner-data",
"allow-restart-miner",
"allow-update-miner-settings"

2. TypeScript Wrapper

File: `src/lib/tauri-api.ts` (NEW)

Created abstraction layer:

getMinerData(ip: string) - Fetches miner data
restartMiner(ip: string) - Restarts miner
updateMinerSettings(ip, frequency, coreVoltage) - Updates settings

Smart detection:

If running in Tauri → uses invoke() to call Rust commands
If running in dev mode → falls back to Next.js API routes
Seamless development experience

3. Frontend Updates

File: `src/components/miner-card.tsx`

Updated:

Import getMinerData, restartMiner, updateMinerSettings from tauri-api
setMinerSettings() now calls updateMinerSettings() instead of fetch
restartMiner() now calls restartMinerTauri() instead of fetch

File: `src/components/miner-dashboard.tsx`

Updated:

Import getMinerData from tauri-api
fetchMinerData() now calls getMinerData() instead of fetch

4. Build Configuration

File: `next.config.ts`

Enabled static export:

export const config = {
  output: 'export',
  images: {
    unoptimized: true
  }
}

File: `src-tauri/tauri.conf.json`

Configured for static build:

{
  "build": {
    "frontendDist": "../out",
    "devUrl": "http://localhost:9002",
    "beforeDevCommand": "npm run dev",
    "beforeBuildCommand": "npm run build"
  }
}

API Routes Status

❌ Removed/Unused (No longer needed)

/api/miner/[ip] - Replaced by Rust command get_miner_data
/api/miner/[ip]/restart - Replaced by Rust command restart_miner
/api/miner/[ip]/settings - Replaced by Rust command update_miner_settings

✅ Kept for Dev Mode

The API routes still exist in the codebase but are only used when running npm run dev (non-Tauri mode). This allows for:

Testing in browser without building Tauri app
Debugging with browser DevTools
Faster iteration during development

Development Workflow

Running in Dev Mode

# Option 1: Tauri Desktop App (recommended)
npm run tauri:dev

# Option 2: Browser Only (for debugging)
npm run dev
# Then open http://localhost:9002

Building for Production

# Build for current platform
npm run tauri:build

# Output:
# Windows: src-tauri/target/release/bundle/nsis/
# macOS: src-tauri/target/release/bundle/dmg/
# Linux: src-tauri/target/release/bundle/appimage/ or /deb/

Troubleshooting

Issue: "Command not found" error

Cause: Permissions not granted in capabilities Fix: Ensure src-tauri/capabilities/default.json includes all allow-* permissions

Issue: Miner data not loading

Cause: Network request failing Fix:

Check console for error messages
Verify miner IP is reachable
Check firewall settings

Issue: Build fails with Rust errors

Cause: Missing Rust dependencies Fix:

cd src-tauri
cargo clean
cargo build

Issue: "Failed to parse" error during dev

Cause: Tauri CLI not finding Rust dependencies Fix:

npm run tauri:dev
# Wait for initial Rust compilation

Testing Checklist

Run npm run tauri:dev successfully
Add a miner and see it fetch data
Restart a miner and verify it works
Adjust miner settings (frequency/voltage)
Enable auto-tuner and watch it work
Test hashrate verification and reversion
Check update notifications work
Build production app: npm run tauri:build
Test production build on your OS
