🚀 Advanced Features

Interactive Mode

FasCraft provides an interactive, guided experience for project creation:

# Start interactive mode
fascraft new

# Follow the guided prompts:
# 1. Enter project name
# 2. Choose project path
# 3. Select project type
# 4. Choose features to include
# 5. Confirm and create

Dry-Run Mode

Preview all changes before applying them:

# See what will be created without making changes
fascraft new my-api --dry-run

# Review project structure, files, and content
# Perfect for understanding what FasCraft will generate

Automatic Backup & Rollback

FasCraft automatically creates backups before destructive operations and provides rollback functionality if anything goes wrong.

# FasCraft automatically creates a backup
fascraft migrate ../legacy-project

# If migration fails, rollback is automatic
# Your original project is safe!
