API Security with NextJS Rewrites and Proxy
Introduction NextJS Proxy and Rewrites are a powerful duo that helps manage and route requests flexibly. NextJS Rewrites act as an internal proxy, essentially mapping one URL path to another. Its biggest advantage is hiding the actual URL of the underlying core server, while transforming requests from Cross-Origin to Same-Origin on the client interface. NextJS Proxy allows you to execute code before a request is completed. As a result, you can easily intervene to implement features like Authentication, authorization, or centralized Rate Limiting, reducing the load on the core API server and maximizing performance. Previously, this function was called middleware, the name change to Proxy aims to confirm that this is an ultra-lightweight Gateway layer: It should only be used for tasks such as Routing, Rewrite, Redirect and managing Header/Cookie.
