@intelligo-dev/next

The Next.js adapter: the one Intelligo package that imports next/*, binding request context, auth routes and Route Handler guards.

Part of Intelligo, an application framework and operational platform for vertical AI SaaS products. Every @intelligo-dev/* package is released at one version and shares one database schema; pnpm dlx @intelligo-dev/cli create my-app installs the set an application needs. Documentation: intelligo.dev/docs/packages/next.

Install

pnpm add @intelligo-dev/next

next and better-auth are peers: the adapter binds into the copies your application already has.

Use

Tell the framework where a request's headers come from — once, from the composition root:

// lib/intelligo.ts
import {
  setBackgroundTaskRunner,
  setRequestContextSource,
} from "@intelligo-dev/core/request-context";
import { nextBackgroundTasks, nextRequestContext } from "@intelligo-dev/next";

setRequestContextSource(nextRequestContext);
setBackgroundTaskRunner(nextBackgroundTasks);

nextBackgroundTasks hands the work the framework starts without awaiting it — auth emails, a new workspace's bootstrap, notification emails — to Next's after(), so a serverless host keeps the function alive until it finishes.

Mount Better-Auth's HTTP handlers:

// app/api/auth/[...all]/route.ts
export { GET, POST } from "@intelligo-dev/next/auth";

Guard a Route Handler. The wrapper resolves the caller first and answers a failed check itself — 401 without a session, 403 without a workspace or the role, with { "error": <code> } as the body. What the handler throws propagates unchanged:

// app/api/invoices/route.ts
import { withRole } from "@intelligo-dev/next/route";

export const GET = withRole(
  ["owner", "admin"],
  async (request, { workspace }) =>
    Response.json(await listInvoices(workspace.id))
);

withAuth needs only a session, withWorkspace an active workspace. Next's own second argument — a dynamic segment's params — arrives third, typed by the wrapper's parameter (Next's generated RouteContext<"/api/invoices/[id]"> fits there too):

// app/api/invoices/[id]/route.ts
export const DELETE = withWorkspace<{ params: Promise<{ id: string }> }>(
  async (request, { workspace }, { params }) => {
    const { id } = await params;
    await deleteInvoice(workspace.id, id);
    return new Response(null, { status: 204 });
  }
);

ActionResult<T> is the shape a Server Action returns to its form — { success: true, data } or { success: false, error } — shared by every registry item's actions:

import type { ActionResult } from "@intelligo-dev/next";

The subpaths are separate so that binding the request context does not load the configured Better-Auth server instance.

Why a package

Every other @intelligo-dev/* package has to be usable from a queue worker, a Hono API, a test, or a product built on something that is not Next. Keeping every next/* import in one package — and having an architecture test refuse it anywhere else — is what makes that true.
