## Overview

TimeSafari provides a simple script-based approach to clear the database for development purposes. This avoids the complexity of programmatic database clearing and provides reliable, platform-specific solutions.

## Quick Start

```bash
# Run the interactive database clearing script
./scripts/clear-database.sh

# Then restart your development server
npm run build:electron:dev  # For Electron
npm run build:web:dev       # For Web
```

## Platform-Specific Approaches

### Electron (Desktop App)

The script automatically detects your platform and clears the SQLite database files:

- **Linux**: `~/.config/TimeSafari/`
- **macOS**: `~/Library/Application Support/TimeSafari/`
- **Windows**: `%APPDATA%\TimeSafari`

### Web Browser

For web browsers, the script provides two approaches:

#### 1. Custom Data Directory (Recommended)

Create an isolated browser profile for development:

```bash
# Create isolated profile
mkdir ~/timesafari-dev-data

# Start browser with custom profile
google-chrome --user-data-dir=~/timesafari-dev-data

# Clear when needed
rm -rf ~/timesafari-dev-data
```

#### 2. Manual Browser Clearing

Use browser DevTools to clear IndexedDB:

1. Open Developer Tools (F12)
2. Go to Application/Storage tab
3. Find 'IndexedDB' section
4. Delete 'TimeSafari' database
5. Refresh the page

## Why Script-Based Approach?

### **Simplicity**
- No complex programmatic database clearing
- No browser storage complications
- No race conditions or permission issues

### **Reliability**
- Direct file system access for Electron
- Isolated browser profiles for web
- Clear, predictable behavior

### **Safety**
- Interactive script guides users
- Platform-specific instructions
- Only clears TimeSafari data

## Manual Commands

If you prefer manual commands:

### Electron
```bash
# Linux
rm -rf ~/.config/TimeSafari/*

# macOS
rm -rf ~/Library/Application\ Support/TimeSafari/*

# Windows
rmdir /s /q %APPDATA%\TimeSafari
```

### Web Browser
```bash
# Create and use isolated profile
mkdir ~/timesafari-dev-data
google-chrome --user-data-dir=~/timesafari-dev-data

# Clear when needed
rm -rf ~/timesafari-dev-data
```

## Best Practices

1. **Stop the development server** before clearing
2. **Use isolated browser profiles** for web development
3. **Restart the development server** after clearing
4. **Backup important data** before clearing
5. **Use the script** for consistent behavior

## Troubleshooting

### Script Not Found
```bash
# Make sure script is executable
chmod +x scripts/clear-database.sh

# Run from project root
./scripts/clear-database.sh
```

### Permission Errors
```bash
# Check file permissions
ls -la ~/.config/TimeSafari/

# Use sudo if needed (rare)
sudo rm -rf ~/.config/TimeSafari/*
```

### Browser Profile Issues
```bash
# Ensure browser is completely closed
pkill -f chrome
pkill -f firefox

# Then clear profile
rm -rf ~/timesafari-dev-data
```
