Deploy Static Files with Rsync over SSH

#!/bin/bash

# --- Configuration ---
LOCAL_DIR="./dist/"                  # Local directory to sync (e.g., your build output)
REMOTE_USER="your_ssh_user"          # SSH username for the remote server
REMOTE_HOST="your_remote_server_ip_or_domain" # Remote server IP or domain
REMOTE_PATH="/var/www/html/mysite/"  # Remote directory where files will be deployed
SSH_KEY_PATH="~/.ssh/id_rsa"         # Path to your private SSH key (optional)

# --- Script Logic ---
echo "Starting deployment to ${REMOTE_HOST}:${REMOTE_PATH}"

# Check if local directory exists
if [ ! -d "${LOCAL_DIR}" ]; then
    echo "Error: Local directory '${LOCAL_DIR}' not found. Please build your project first."

# Use rsync to synchronize files
# -a: archive mode (preserves permissions, timestamps, etc.)
# -v: verbose output
# -z: compress file data during transfer
# --delete: delete extraneous files from destination dirs (optional, use with caution)
# -e "ssh -i ${SSH_KEY_PATH}": specify SSH command with identity file (if not using default)
