CORS Policy Configurator
Configures secure Cross-Origin Resource Sharing (CORS) policies for .NET and Python backends with environment-specific logic.
The ln-773-cors-configurator is an automated tool designed to implement robust Cross-Origin Resource Sharing (CORS) policies across development and production environments. It intelligently detects frontend frameworks like React, Vite, and Angular to suggest appropriate origins, while enforcing security best practices such as disabling wildcards in production and requiring environment-variable-driven origin lists. By providing separate configurations for local development and live deployments, it ensures a seamless developer experience without compromising security or API integrity.
