feat(middleware): add light mode

[baptadn]

Light mode

The response rewriting features (e.g., SEO overrides, custom body, etc.) of redirection.io are currently not compatible with React Server Components (RSC). This is due to the fact that Vercel’s middleware implementation does not follow standard middleware protocols, requiring us to fetch requests, which is incompatible with both RSC and Vercel’s implementation.

However, we provide a light mode that supports RSC by offering only the redirection functionality. To enable this mode, simply set the mode option to light.

This allows you to implement redirection behavior without modifying response content, ensuring smooth operation with RSC.

const middleware = createRedirectionIoMiddleware({
    // …
    mode: "light",
});
