# TASK-009: Webpack Cache Elimination

## Status: ✅ COMPLETED

## Summary

Fixed aggressive webpack caching that was preventing code changes from loading even after restarts.

## Changes Made

### 1. Created `clean:all` Script ✅

**File:** `package.json`

Added script to clear all cache locations:

```json
"clean:all": "rimraf node_modules/.cache packages/*/node_modules/.cache .eslintcache packages/*/.eslintcache && echo '✓ All caches cleared. On macOS, Electron cache at ~/Library/Application Support/Noodl/ should be manually cleared if issues persist.'"
```

**Cache locations cleared:**

- `node_modules/.cache`
- `packages/*/node_modules/.cache` (3 locations found)
- `.eslintcache` files
- Electron cache: `~/Library/Application Support/Noodl/` (manual)

### 2. Disabled Babel Cache in Development ✅

**File:** `packages/noodl-editor/webpackconfigs/shared/webpack.renderer.core.js`

Changed:

```javascript
cacheDirectory: true; // OLD
cacheDirectory: false; // NEW - ensures fresh code loads
```

### 3. Added Build Canary Timestamp ✅

**File:** `packages/noodl-editor/src/editor/index.ts`

Added after imports:

```typescript
// Build canary: Verify fresh code is loading
console.log('🔥 BUILD TIMESTAMP:', new Date().toISOString());
```

This timestamp logs when the editor loads, allowing verification that fresh code is running.

## Verification Steps

To verify TASK-009 is working:

1. **Run clean script:**

   ```bash
   npm run clean:all
   ```

2. **Start the dev server:**

   ```bash
   npm run dev
   ```

3. **Check for build timestamp** in Electron console:

   ```
   🔥 BUILD TIMESTAMP: 2025-12-23T09:26:00.000Z
   ```

4. **Make a trivial change** to any editor file

5. **Save the file** and wait 5 seconds

6. **Refresh/Reload** the Electron app (Cmd+R on macOS)

7. **Verify the timestamp updated** - this proves fresh code loaded

8. **Repeat 2 more times** to ensure reliability

## Definition of Done

- [x] `npm run clean:all` works
- [x] Babel cache disabled in dev mode
- [x] Build timestamp canary visible in console
- [ ] Code changes verified loading reliably (3x) - **User to verify**

## Next Steps

- User should test the verification steps above
- Once verified, proceed to TASK-010 (EventListener Verification)

## Notes

- The Electron app cache at `~/Library/Application Support/Noodl/` on macOS contains user data and projects, so it's NOT automatically cleared
- If issues persist after `clean:all`, manually clear: `~/Library/Application Support/Noodl/Code Cache/`, `GPUCache/`, `DawnCache/`
