Description: Flask-Cors is an extension for Flask that facilitates the implementation of CORS (Cross-Origin Resource Sharing) in web applications. CORS is a security mechanism that allows browsers to make requests to different domains than the one that served the original web page. This is especially relevant in modern applications that use microservices architectures or require interaction between different domains. Flask-Cors simplifies the configuration of CORS by providing a straightforward interface to enable it on specific routes or throughout the application. Its main features include the ability to define access policies, specify allowed methods, and manage custom headers. The extension is highly configurable, allowing developers to tailor CORS rules to the specific needs of their application. Its relevance lies in the growing need for secure interactions between different origins in web development, making it an essential tool for any developer working with APIs and modern web applications.
