Authentication is a critical feature for most web applications. NextAuth.js (now part of the Auth.js project) is a complete open-source authentication solution for Next.js applications. It's designed to be easy to use and supports a wide range of providers.
Step 1: Installation and Setup
First, add the necessary packages to your project:
npm install next-auth
Next, create a dynamic route handler at app/api/auth/[...nextauth]/route.ts. This file will contain all your NextAuth.js configuration.
// app/api/auth/[...nextauth]/route.ts
import NextAuth from "next-auth";
import GithubProvider from "next-auth/providers/github";
import GoogleProvider from "next-auth/providers/google";
export const authOptions = {
providers: [
GithubProvider({
clientId: process.env.GITHUB_ID,
clientSecret: process.env.GITHUB_SECRET,
}),
GoogleProvider({
clientId: process.env.GOOGLE_CLIENT_ID,
clientSecret: process.env.GOOGLE_CLIENT_SECRET,
}),
],
secret: process.env.NEXTAUTH_SECRET,
};
const handler = NextAuth(authOptions);
export { handler as GET, handler as POST };Read More
