Performance: Installing Flask
LOW IMPACT
This affects the initial page load speed indirectly by adding to the backend server setup time and the size of the deployed application.
Setting up a Python web server with Flask
Flask
pip install flask
Installs the latest stable Flask version with performance improvements and security patches.
📈 Performance GainImproved backend startup and response times with smaller security risks
