Lucia 2.6: Migrate to v3 Next.js middleware API

[pilcrowonpaper]

In Lucia 2.6, we introduced a new middleware: nextjs_future()

This will replace the existing nextjs() middleware in v3. While nextjs() won't be deprecated, we recommend migrating early. This newer middleware makes every a bit more consistent and properly supports the experimental form actions. To migrate, replace nextjs() with nextjs_future() middleware.

import { nextjs_future } from "lucia/middleware"

export const auth = lucia({
  adapter: nextjs_future()
});

If you're using Next.js 12 or the Pages Router, there are no changes. For Next.js 13 users, here are the new APIs:

// page.tsx
import * as context from "next/headers";

export default () => {
	const authRequest = auth.handleRequest("GET", context);

	const actions = async () => {
		const authRequest = auth.handleRequest("POST", context);
	};
	// ...
};

// API routes
import * as context from "next/headers";

export const POST = async (request: NextRequest) => {
	const authRequest = auth.handleRequest(request.method, context);
	// ...
};
