# 🔧 Fixes Applied

## Issues Fixed

### 1. Database Directory Creation Error ✅
**Problem:** `SQLITE_CANTOPEN: unable to open database file`
**Root Cause:** The `db/` directory didn't exist and wasn't automatically created
**Solution:** Modified scripts to create directory if missing

### 2. Session Directory Management ✅
**Problem:** Session directory might not exist at runtime
**Root Cause:** Directory wasn't being created
**Solution:** Now created automatically when server starts

### 3. Missing .env File ✅
**Problem:** Configuration not available
**Solution:** Default `.env` file provided with sensible defaults

## Files Modified

### `src/db.js`
Added directory creation logic:
```javascript
const dir = path.dirname(dbPath);
if (!fs.existsSync(dir)) {
  fs.mkdirSync(dir, { recursive: true });
}
```

### `scripts/initDb.js`
Added explicit directory creation and better error messages

### `scripts/seedDb.js`
Added directory creation before database initialization

## Files Added

### `.env` (Default Configuration)
- PORT=3000
- NODE_ENV=development
- Default admin credentials
- OIDC settings

### `.gitkeep` Files
- `db/.gitkeep` - Ensures db/ directory is tracked by git
- `sessions/.gitkeep` - Ensures sessions/ directory is tracked by git

### Setup Scripts
- `setup.sh` - Automated setup for Linux/Mac
- `setup.bat` - Automated setup for Windows
- `verify.sh` - Verify installation is complete

### Documentation
- `LINUX-QUICKSTART.md` - Quick start guide for Linux users

## Testing

To verify all fixes are working:

```bash
# Clean start
rm -rf db/ sessions/ node_modules/

# Reinstall
npm install

# Initialize (should now work!)
npm run init-db

# Verify
npm run dev
```

## What Changed in Summary

| Component | Before | After |
|-----------|--------|-------|
| Directory Creation | Manual | Automatic |
| Error Handling | Basic | Detailed |
| Configuration | Manual setup | `.env` provided |
| Verification | None | `verify.sh` script |
| Setup Process | Multi-step | `setup.sh` script |

## Backward Compatibility

All changes are backward compatible. Existing setups will continue to work, and the automatic directory creation only triggers if directories don't exist.

## Next Steps

For users encountering the original issue:

1. ✅ Pull latest changes
2. ✅ Run `npm run init-db` (should now work)
3. ✅ Run `npm run dev`
4. ✅ Visit http://localhost:3000
