PlanAI Editor Python Backend

This Python backend serves as the server component for the PlanAI Editor application. It provides the following functionality:

1. Code Generation: Converts visual graph representations (nodes and edges) from the frontend into executable PlanAI Python code.
2. Module Loading: Dynamically loads and validates the generated Python modules to ensure they are syntactically correct.
3. WebSocket Communication: Uses Flask-SocketIO to establish real-time communication with the frontend for sending graph data and receiving generated code.

Key Components

• Flask Application: Serves as the main web server
• SocketIO: Handles real-time bidirectional communication with the frontend
• Code Generation: Transforms visual graph data into Python code with proper imports, task definitions, worker definitions, and graph setup
• Black Formatter: Ensures generated code follows consistent formatting standards

API Endpoints

The backend primarily communicates through WebSocket events:

• connect: Handles client connections
• disconnect: Handles client disconnections
• export_graph: Receives graph data from the frontend, generates Python code, and attempts to load it
• export_result: Sends the result of the code generation and loading process back to the frontend

Running the Backend

The server runs on port 5001 by default, separate from the SvelteKit frontend development server.
