Watch-Sync

A Go console application that watches directories for changes and synchronizes them using various protocols (FTP, SFTP, Rsync).

Features

• File System Watching: Monitors a directory for file/folder creation, modification, and deletion
• Recursive Watching: Detects changes in subdirectories
• Multiple Sync Methods:
  • FTP upload
  • SFTP upload
  • Rsync synchronization (preserves directory structure)
• Configurable: Uses JSON configuration file stored in the user's home directory
• Graceful Shutdown: Properly cleans up resources on exit
• Ignores CHMOD Events: Avoids unnecessary syncs for permission changes

Installation

Using Go

# Build and install
make install

From Binary

Download the latest binary from the releases page.

Usage

# Watch the current directory with no actions
watch-sync

# Watch a specific directory
watch-sync -path /path/to/watch

# Watch with specific actions to trigger
watch-sync -actions prod-ftp,staging-sftp

# Watch a specific path with specific actions
watch-sync -path /path/to/watch -actions backup-rsync

# Watch without recursion (top level only)
watch-sync -recursive=false -actions prod-ftp

# Enable verbose logging
watch-sync -verbose -actions backup-rsync

Configuration

The configuration file is stored at ~/.watch-sync.json. If it doesn't exist, a default one will be created.

Example configuration:

{
  "actions": {
    "prod-ftp": {
      "type": "ftp",
      "settings": {
        "host": "ftp.example.com",
        "port": 21,
        "user": "username",
        "password": "password",
        "remote_dir": "/public_html"
      }
    },
    "staging-sftp": {
      "type": "sftp",
      "settings": {
        "host": "sftp.example.com",
        "port": 22,
        "user": "username",
        "password": "password",
        "key_file": "/path/to/private_key",
        "remote_dir": "/var/www"
      }
    },
    "backup-rsync": {
      "type": "rsync",
      "settings": {
        "host": "example.com",
        "user": "username",
        "remote_dir": "/var/www/html",
        "options": "-av --delete"
      }
    }
  },
  "filters": {
    "exclude": [".git", "node_modules", "*.tmp", "vendor", "*.log"]
  }
}

With this configuration, you can reference your actions by name when running the command:

watch-sync -actions prod-ftp,staging-sftp

Recent Improvements

• Fixed rsync path preservation: rsync now correctly preserves directory structure on the remote server
• Ignore CHMOD events: CHMOD events no longer trigger synchronization actions
• Better error handling: Improved error logging and recovery
