MIDIMon v2.4 Plugin Marketplace - Deployment Guide

Target: Production release of Plugin Marketplace feature Status: Phase 2 Complete - Ready for deployment Estimated Time: 15-30 minutes

Prerequisites Checklist

✅ All code committed (7 commits)
✅ All tests passing (8/8 = 100%)
✅ Release build successful (3m 54s)
✅ Plugin binaries built and checksums generated
✅ Registry structure created (plugins/registry/)
✅ Documentation complete (~3,300 lines)

Step 1: Prepare Plugin Binaries (5 min)

1.1 Locate Existing Plugin Binaries

The plugin binaries are already built and located at:

~/Library/Application Support/midimon/plugins/
├── spotify/
│   └── libmidimon_spotify_plugin.dylib  (4.6 MB)
└── obs/
    └── libmidimon_obs_plugin.dylib      (1.9 MB)

1.2 Copy Binaries to Release Directory

# Create release staging directory
mkdir -p ~/Desktop/midimon-plugins-v2.4.0

# Copy plugin binaries
cp ~/Library/Application\ Support/midimon/plugins/spotify/libmidimon_spotify_plugin.dylib \
   ~/Desktop/midimon-plugins-v2.4.0/libmidimon_spotify_plugin-aarch64-apple-darwin.dylib

cp ~/Library/Application\ Support/midimon/plugins/obs/libmidimon_obs_plugin.dylib \
   ~/Desktop/midimon-plugins-v2.4.0/libmidimon_obs_plugin-aarch64-apple-darwin.dylib

# Verify files
ls -lh ~/Desktop/midimon-plugins-v2.4.0/

1.3 Verify Checksums Match Registry

cd ~/Desktop/midimon-plugins-v2.4.0/

# Verify Spotify checksum
shasum -a 256 libmidimon_spotify_plugin-aarch64-apple-darwin.dylib
# Expected: d9c84a75ac0193669ac114cd00b1428088b96f3ebad757e3f8728c6c5078f488

# Verify OBS checksum
shasum -a 256 libmidimon_obs_plugin-aarch64-apple-darwin.dylib
# Expected: 6ba95374b5af8f71b3b3634a55cd21c37c9644493299555ab5aac50b0a56c45b

Step 3: Verify Registry Access (2 min)

3.1 Test Registry URL

# Test registry fetch
curl -I https://raw.githubusercontent.com/amiable-dev/midimon/main/plugins/registry/registry.json

# Should return: HTTP/2 200

3.2 Test Plugin Download URLs

# Test Spotify download
curl -I https://github.com/amiable-dev/midimon/releases/download/v2.4.0-plugins/libmidimon_spotify_plugin-aarch64-apple-darwin.dylib

# Should return: HTTP/2 302 (redirect to actual file)

# Test OBS download
curl -I https://github.com/amiable-dev/midimon/releases/download/v2.4.0-plugins/libmidimon_obs_plugin-aarch64-apple-darwin.dylib

# Should return: HTTP/2 302 (redirect to actual file)

3.3 Verify Checksums in Registry

Open plugins/registry/registry.json and confirm:

Spotify checksum matches: d9c84a75ac0193669ac114cd00b1428088b96f3ebad757e3f8728c6c5078f488
OBS checksum matches: 6ba95374b5af8f71b3b3634a55cd21c37c9644493299555ab5aac50b0a56c45b

Step 4: Update Registry URLs (if needed) (3 min)

If you created the release under a different repository or organization, update the download URLs in plugins/registry/registry.json:

{
  "downloads": {
    "macos-aarch64": "https://github.com/YOUR-ORG/midimon/releases/download/v2.4.0-plugins/libmidimon_spotify_plugin-aarch64-apple-darwin.dylib"
  }
}

Then commit and push:

git add plugins/registry/registry.json
git commit -m "fix(registry): Update download URLs for v2.4.0-plugins release"
git push origin main

Step 5: Manual Testing (Optional, 10-15 min)

5.1 Launch Tauri Dev Mode

cd /Users/christopherjoseph/projects/amiable/midimon/midimon-gui/src-tauri
cargo tauri dev

5.2 Test Plugin Marketplace Workflow

Open Plugin Marketplace Tab
- Navigate to "Plugins" or "Marketplace" tab
- UI should load without errors
Fetch Registry
- Click "Refresh" or "Fetch Plugins"
- Should display 2 plugins (Spotify, OBS)
- Verify categories and tags display correctly
Install Plugin
- Click "Install" on Spotify plugin
- Progress should be shown (or instant if small)
- After completion, plugin should appear as "Installed"
- Check: ~/Library/Application Support/midimon/plugins/spotify/
Verify Installation
- Plugin should appear in installed list
- Plugin manifest should be created
- Binary checksum should be verified
Uninstall Plugin
- Click "Uninstall" on Spotify plugin
- Confirm dialog should appear
- After confirmation, plugin should disappear from installed list
- Check: Directory should be deleted
Test Search/Filter
- Search for "spotify" - should show Spotify plugin
- Search for "obs" - should show OBS plugin
- Filter by category "streaming" - should show both
- Filter by category "media" - should show both

5.3 Test Error Scenarios

Network Failure
- Disconnect internet
- Try to fetch registry
- Should show error message (not crash)
Invalid Plugin
- Try to install non-existent plugin
- Should show error message
Checksum Mismatch (hard to test)
- Would require tampering with download
- Skip for now, trust the implementation

Step 6: UI Polish (Optional, 1-2 hours)

6.1 Install Toast Notification Library

cd /Users/christopherjoseph/projects/amiable/midimon/midimon-gui/ui
npm install svelte-french-toast

6.2 Replace Alert Dialogs

Edit PluginMarketplace.svelte:

import toast from 'svelte-french-toast';

// Replace alert() calls:
// Before:
alert(`Plugin "${pluginId}" installed successfully!`);

// After:
toast.success(`Plugin "${pluginId}" installed successfully!`);

6.3 Add Loading States

let isInstalling = false;

async function installPlugin(pluginId) {
  isInstalling = true;
  try {
    await invoke('install_plugin_from_registry', { pluginId });
    toast.success(`Plugin "${pluginId}" installed!`);
  } catch (e) {
    toast.error(`Failed to install: ${e}`);
  } finally {
    isInstalling = false;
  }
}

6.4 Add Progress Indicators

This requires backend changes to emit progress events. Skip for v2.4.0, defer to v2.4.1.

Step 7: Create Release Notes (5 min)

7.1 Update CHANGELOG.md

cd /Users/christopherjoseph/projects/amiable/midimon

Troubleshooting

Issue: Registry fetch fails

Test with curl: curl -L <URL>

Issue: Download fails

Solution:

Verify release was published (not draft)
Check binary was uploaded correctly
Test download URL with curl
Verify URL format matches registry

Issue: Checksum mismatch

Solution:

Regenerate checksum: shasum -a 256 plugin.dylib
Update registry.json with new checksum
Commit and push changes
Wait 1-2 minutes for GitHub raw CDN to update

Issue: Plugin won't load

Solution:

Check plugin binary is executable: chmod +x plugin.dylib
Verify manifest exists: cat plugin.toml
Check daemon logs for errors
Ensure capabilities are granted
