Transitioning from Python to Spruce

Python development often involves using dynamic scripting languages and various frameworks like Django or Flask. Spruce, on the other hand, uses TypeScript. This guide will help you connect your Python expertise to Spruce’s architecture, showing how to adapt and apply your existing skills in a new environment.

Key Differences between Python and Spruce Development

	Python	Spruce
Programming Language	Python	TypeScript
IDE	PyCharm, VS Code	Visual Studio Code
App Lifecycle	Depends on the framework or context	No Equivalent
UI Design	Tkinter for desktop GUI, Frameworks like Django or Flask for web	Heartwood, ViewControllers
Event Handling	Event loops in frameworks, Callbacks	Mercury
Data Persistence	SQLite, SQLAlchemy, Django ORM	Data Stores
Error Handling	Try-Except Blocks	Try-Catch Blocks, SpruceErrors
Testing	Unittest, PyTest	Jest, Testing Library
User Authentication	Depends on the framework; Flask-Login, Django’s auth system	Mercury, Authenticator
User Permissions	Framework-specific; Django’s permission framework, Flask-Principal	Mercury, Authorizor
