First, let's let the code get the word out...

before

middleware.ts

import { NextRequest } from 'next/server';

export const middleware = async (req: NextRequest) => {
  let user = undefined;
  let team = undefined;
  const token = req.headers.get('token');

  if(req.nextUrl.pathname.startsWith('/auth')) {
    user = await getUserByToken(token);

    if(!user) {
      return NextResponse.redirect('/login');
    }

    return NextResponse.next();
  }

  if(req.nextUrl.pathname.startsWith('/team/') || req.nextUrl.pathname.startsWith('/t/')) {
    user = await getUserByToken(token);

    if(!user) {
      return NextResponse.redirect('/login');
    }

    const slug = req.nextUrl.query.slug;
    team = await getTeamBySlug(slug);

    if(!team) {
      return NextResponse.redirect('/');
    }

    return NextResponse.next();
  }

  return NextResponse.next();
}

export const config = {
  matcher: ['/((?!_next/|_static|_vercel|[\\w-]+\\.\\w+).*)'],
};

after

middleware.ts

import { createNEMO, type MiddlewareFunctionProps } from '@rescale/nemo';
import { auth } from '@/app/(auth)/auth/_middleware';
import { team } from '@/app/(team)/team/_middleware';

const globalMiddlewares = {
  before: auth, // OR: [auth, ...]
};

const middlewares = {
  '/auth/:path*': auth,
  '/(team|t)/:slug/:path*': team, // OR: [team, ...]
};

export const middleware = createNEMO(middlewares, globalMiddlewares);

export const config = {
  matcher: ['/((?!_next/|_static|_vercel|[\\w-]+\\.\\w+).*)'],
};

Do you feel the difference?
