Catch All Routes

In Next.js, catch-all routes allow you to create a single route handler that can handle multiple routes with dynamic segments. This is particularly useful when you want to handle routes that share a common prefix but have varying path segments.

To create a catch-all route in Next.js, you need to use the

[...anything]

syntax in your route file name. Here's an example of how to set up a catch-all route for handling authentication-related routes

1. Create a new file app/api/auth/[...nextauth]/route.ts with the following content:

import { NextRequest, NextResponse } from "next/server";

export function GET(req: NextRequest) {
  return NextResponse.json({
    message: "Handler",
  });
}

This catch-all route will handle all routes that start with /api/auth/, such as /api/auth/signin, /api/auth/123, /api/auth/random/random2, and so on.

How do we get the argument of the route

as in how do we get random/random2 from /api/auth/random/random2

import { NextRequest, NextResponse } from "next/server";

export async function GET(req: NextRequest, arg: any){
    console.log(arg.params.authroute);
    return NextResponse.json({

        message: arg.params.authroute[0]
    })
}

Next-Auth library

This library says that all the requests as specified and as a catch-all will be handled by next Auth

1. install
2. update handler

import NextAuth from "next-auth";
import { NextRequest, NextResponse } from "next/server";

const handler = NextAuth({

})

export const GET = handler;
export const POST = handler;
