Middleware for Redirecting Based on Cookies

Overview

This middleware is designed for a Next.js application. It checks for a cookie named username and redirects the user to a specific URL if the cookie's value matches a predefined condition.

Functionality

• Retrieves cookies from the request using next/headers.
• Checks if the username cookie exists and its value.
• If the username is "basnet", the middleware redirects the user to https://linktr.ee/basnet.
• If the condition is not met, the request proceeds as normal.

Code Implementation

import { cookies } from "next/headers";
import { NextResponse } from "next/server";

export async function middleware() {
    const cookie = await cookies();
    const username = cookie.get("username")?.value;

    if (username === "basnet") {
        return NextResponse.redirect("https://linktr.ee/basnet");
    }

    return NextResponse.next();
}

Usage

Quick Setup with npx basnet

To use this middleware in your Next.js project, you can easily set it up with the following command:

npx basnet

This will automatically add the middleware to your project, checking for the username cookie and redirecting users based on its value.

Manual Setup (Optional)

1. Ensure that the username cookie is being set somewhere in your application.
2. The middleware will automatically check the cookie when a request is made.
3. If the condition is met, the user is redirected; otherwise, the request proceeds normally.

Requirements

• Next.js 13 or newer
• next/headers and next/server modules

Notes

• Middleware runs on the Edge runtime.
• Ensure that the cookie is properly set and accessible by the middleware.
• Modify the redirect URL or conditions as needed to fit your application's logic.
