If you want to avoid the full OIDC redirection flow (Sign in with Authgear), you are likely looking for the Custom UI approach using the @authgear/web SDK.

For Next.js App Router (SSR), using OIDC/cookies is usually the most secure and standard way (via @authgear/nextjs). If you strictly want a custom login form inside your Next.js app calling your NestJS backend (or Authgear directly), check the Authentication via API docs (if enabled on your plan). However, the React SPA guide you linked mostly assumes client-side auth. For Next.js + NestJS, the standard OIDC flow is typically recommended for security unless you have a specific reason to avoid redirects.

I am using ssr app router nextjs for frontend and nest backend. So how I should add auth provider?I should have next server and next frontend and nest api backend? I want add Authgear. What guide I should follow. They have guide for react spa and guide for regular web app nextjs but it is out of date.

Hi @nkur8903
For Next.JS integration, the recommended way is to use the next-auth.js package (https://next-auth.js.org/) and then add Authgear as an OIDC provider
Were you able to follow the Part 2 - Step 2 in this guide? https://docs.authgear.com/get-started/regular-web-app/next.js#step-2-installing-nextauth.js
