What is CORS?
CORS, short for Cross-Origin Resource Sharing, is a security feature found in web browsers. Its job is to stop scripts on one webpage from asking for things from another domain. It sets up rules to decide if a web app on one site (like domain.com) can get stuff from a different site (like api.domain.com). This keeps users safe from bad scripts that might try to steal their info or do things they shouldn’t on other websites.
How to use CORS in Next.js to Handle Cross-origin Requests ?
NextJS simplifies server-side logic with its API routes, reducing the need for separate server maintenance. CORS, usually configured on the server, can be handled within NextJS API routes directly. These routes, integrated into the application codebase, allow control over request origins. By implementing CORS in API routes, NextJS ensures secure and controlled access to server resources. This approach aligns with NextJS’s server-side rendering capabilities. Developers benefit from reduced complexity and streamlined maintenance.
NextJS emerges as a favorable framework for building applications with server-side rendering needs. Its integration of CORS management within API routes enhances security and flexibility. This model offers a unified solution for both client and server-side needs, promoting efficient development practices.
