CORS, or Cross-Origin Resource Sharing, is a crucial mechanism for controlling access to resources from different origins. It plays an essential role in web security, especially for applications that communicate with various API servers. In this article, the author explains how CORS works, the basic headers involved, and how developers can manipulate them to allow or restrict access. One key point made is that without proper CORS configuration, modern applications may face issues accessing essential resources. The article also provides real-world examples of CORS usage in different scenarios, illustrating how widely this standard is implemented. Understanding CORS is a necessary skill for any developer working with cross-origin requests and aiming to maintain secure access to resources.
