What is the preferred/recommended way to implement protected routes?

I gave https://tanstack.com/router/latest/docs/framework/react/guide/authenticated-routes a read and was still unsure what the preferred way would be, using Tanstack Router. The _authenticated.tsx is rather simple but fits really well. And I'm still unsure what the approach would be if I had a RBAC requirement for my routes. In a way that people without the expected claims/roles would not be able to view these routes.

Authenticated Routes | TanStack Router React Docs

Authentication is an extremely common requirement for web applications. In this guide, we'll walk through how to use TanStack Router to build protected routes, and how to redirect users to login if they try to access them. The route.beforeLoad Option

Could you just throw a not found error for unauthenticated users?

optimistic-goldOP•2y ago

what

You can have a layout route that will check the user has the necessary roles to access any child routes. You can use the notFound() function to show a 404 page for anyone without the necessary roles. https://tanstack.com/router/latest/docs/framework/react/api/router/notFoundFunction#notfound-function

notFound function | TanStack Router React Docs

The notFound function returns a new NotFoundError object that can be either returned or thrown from places like a Route's beforeLoad or loader callbacks to trigger the notFoundComponent. notFound options

If you have multiple sets of roles, you could create multiple layout routes for each set of roles.

optimistic-goldOP•2y ago

Oh yeah sure But then how would I check what are the required roles for the given route? Without having to hardcode everything in the layout route any suggestions @camburris ?

You can setup your auth context to store the user if they are logged in (null otherwise) and store the user roles as part of that user object. Then in the route you can do something like

export const Route = createFileRoute("/_authenticated/admin")({
  beforeLoad: ({ context, location }) => {
    if (!context.auth.user?.roles.find((role) => role.name === "Admin")) {
      throw redirect({
        to: "/auth/login",
        search: {
          redirect: location.href,
        },
      });
    }
  },
});

export const Route = createFileRoute("/_authenticated/admin")({
  beforeLoad: ({ context, location }) => {
    if (!context.auth.user?.roles.find((role) => role.name === "Admin")) {
      throw redirect({
        to: "/auth/login",
        search: {
          redirect: location.href,
        },
      });
    }
  },
});

or at least thats how I've been doing it

My problem is that I have really granular permissions so it'd be your scenario but with kind of with one role per page and I don't want to have these permissions hardcoded in the layout

fascinating-indigo•2y ago

Why hardcoding in the layout? Inside beforeLoad you have access to the context, you can move all your logic inside a hook and just call something like auth.isAuthorized(user, location.href) in the route as in the example above

optimistic-goldOP•2y ago

Doesn't this still imply I'll have it hardcoded somewhere? All of them, together. I was hoping to be able to declare each required claim or role in the specific route file.

optimistic-goldOP•2y ago

I'll take a look thanks Nah it still doesn't solve my issue sadly I suppose I could use some "reflection" to load the permissions from each route dynamically and aggregate them into a map. Either that or writing a build script and I'm not a fan of this idea.

fascinating-indigo•2y ago

Why you can't just write the rules in a map directly? Can you share how the definition of permissions for a single route looks like? I have the feeling you're overcomplicating it

optimistic-goldOP•2y ago

I can. I just wanted to have each route containing the permission they need. And aggregate it all automatically. It's just claims

fascinating-indigo•2y ago

Ah ok, got it! I don't know if maybe you can append some kind of metadata to routes and try to grab them all from the generated routes 🤔

optimistic-goldOP•2y ago

btw apparently not even this is working for some reason gave this a quick try and it appears as if it's not going through my _authenticated.tsx

// src/routes/_authenticated.tsx
import { createFileRoute, redirect } from "@tanstack/react-router";

export const Route = createFileRoute("/_authenticated")({
  beforeLoad: async ({ location }) => {
    throw redirect({
      to: "/login",
      search: {
        redirect: location.href,
      },
    });
  },
});

// src/routes/_authenticated.tsx
import { createFileRoute, redirect } from "@tanstack/react-router";

export const Route = createFileRoute("/_authenticated")({
  beforeLoad: async ({ location }) => {
    throw redirect({
      to: "/login",
      search: {
        redirect: location.href,
      },
    });
  },
});

Nothing really happens This is my root.tsx:

import { DashboardShell } from "@/components/dashboard-shell";
import { createRootRoute, Outlet } from "@tanstack/react-router";
import { lazy } from "react";

const TanStackRouterDevtools =
  process.env.NODE_ENV === "production"
    ? () => null
    : lazy(() =>
        import("@tanstack/router-devtools").then((res) => ({
          default: res.TanStackRouterDevtools,
        }))
      );

export const Route = createRootRoute({
  component: () => (
    <DashboardShell>
      <Outlet />
      <TanStackRouterDevtools />
    </DashboardShell>
  ),
});

import { DashboardShell } from "@/components/dashboard-shell";
import { createRootRoute, Outlet } from "@tanstack/react-router";
import { lazy } from "react";

const TanStackRouterDevtools =
  process.env.NODE_ENV === "production"
    ? () => null
    : lazy(() =>
        import("@tanstack/router-devtools").then((res) => ({
          default: res.TanStackRouterDevtools,
        }))
      );

export const Route = createRootRoute({
  component: () => (
    <DashboardShell>
      <Outlet />
      <TanStackRouterDevtools />
    </DashboardShell>
  ),
});

And this is the generated routeTree ```ts import { createFileRoute } from '@tanstack/react-router' // Import Routes import { Route as rootRoute } from './routes/root' import { Route as AuthenticatedImport } from './routes/_authenticated' // Create Virtual Routes const LoginLazyImport = createFileRoute('/login')() const AboutLazyImport = createFileRoute('/about')() const IndexLazyImport = createFileRoute('/')() // Create/Update Routes const LoginLazyRoute = LoginLazyImport.update({ path: '/login', getParentRoute: () => rootRoute, } as any).lazy(() => import('./routes/login.lazy').then((d) => d.Route)) const AboutLazyRoute = AboutLazyImport.update({ path: '/about', getParentRoute: () => rootRoute, } as any).lazy(() => import('./routes/about.lazy').then((d) => d.Route)) const AuthenticatedRoute = AuthenticatedImport.update({ id: '/_authenticated', getParentRoute: () => rootRoute, } as any) const IndexLazyRoute = IndexLazyImport.update({ path: '/', getParentRoute: () => rootRoute, } as any).lazy(() => import('./routes/index.lazy').then((d) => d.Route)) // Populate the FileRoutesByPath interface declare module '@tanstack/react-router' { interface FileRoutesByPath { '/': { preLoaderRoute: typeof IndexLazyImport parentRoute: typeof rootRoute } '/_authenticated': { preLoaderRoute: typeof AuthenticatedImport parentRoute: typeof rootRoute } '/about': { preLoaderRoute: typeof AboutLazyImport parentRoute: typeof rootRoute } '/login': { preLoaderRoute: typeof LoginLazyImport parentRoute: typeof rootRoute } } } // Create and export the route tree export const routeTree = rootRoute.addChildren([ IndexLazyRoute, AboutLazyRoute, LoginLazyRoute, ])

``
Wtf is happening
oh yeah it's not going through

_authenticated.tsx's beforeLoad

 at all
yeah idk what is happening
huh so my routes would need to be

_authenticated.XXX.tsx`?
