What is a CORS Error?
Every JavaScript developer has faced the frustration of dealing with Cross-Origin Resource Sharing (CORS) issues. It's one of the most common and annoying errors in web development, blocking your app from accessing APIs and resources on different domains.
CorsProxy allows web applications to securely access resources from different domains, overcoming browser restrictions. It simplifies API integration, enhances security, and improves user experience by enabling seamless interaction with third-party services.
Access to XMLHttpRequest at 'https://api.example.com' from origin 'http://localhost:8100' has been blocked by CORS policy:
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
