How to change the base path in nextjs?

Understand the base path configuration in nextjs with easy ways.

You can change the base path in nextjs. Base path help distribute the nextjs app on a different subdomain.

/** @type {import('next').NextConfig} */
const nextConfig = {
reactStrictMode: true, basePath: '/blog',}module.exports = nextConfig

Now your application serves on http://localhost:3000/blog.

Now, if you access your application on http://localhost:3000, you face a 404 error.

How to use the nextjs base path in-app?

In next/link component, nextjs automatic generate a path with a combined base path + /about and your base is http://localhost:3000/blog/about

<Link href="/page"><a>about</a></Link>

Now the access your public folder image with /blog in your project.

<Image   width={724}   height={324}   objectFit="cover"   src="/blog/vercel.svg"   alt="vercel logo "/>

In nextjs your images in the asset folder, you cannot access an image with a base path. You import images and use them.

import heavyrain from '../Images/heavy-rain.jpg'export default function Home() {return (     <Image         width={724}         height={324}         objectFit="cover"         src={heavyrain}         alt="vercel logo "    />  )}

In nextjs, you use the useRouter hook in the component—useRouter hook return basepath. No difference in useRouter hook functionality with base

let router= useRouter()console.log(router.basePath,' router ');
