What is Next.js?

Next.js is a powerful React framework that makes web development easier. It boasts features like hybrid static and server rendering, TypeScript support, smart bundling, and route pre-fetching. In addition to these built-in features, there are numerous libraries built around Next.js that make it even more powerful.

Introducing the Top Next.js Libraries

Here are three notable Next.js libraries that have risen to prominence in 2023.

1. SWR

SWR is a React Hooks library for remote data fetching. Staple to Next.js, it simplifies fetching and revalidating data, thereby enhancing Next.js's capabilities.

Here's an example of how you can use SWR:

import useSWR from 'swr'

function Profile() {
  const { data, error } = useSWR('/api/user', fetch)

  if (error) return <div>Failed to load</div>
  if (!data) return <div>Loading...</div>

  return <div>Hello, {data.name}!</div>
}

2. NextAuth.js

NextAuth.js is a complete solution for all your authentication needs in Next.js applications. It's easy to set up and works with various providers.

Check out this sample code showing how to utilize NextAuth.js:

import Providers from 'next-auth/providers'

export default NextAuth({
  providers: [
    Providers.GitHub({
      clientId: process.env.GITHUB_CLIENT_ID,
      clientSecret: process.env.GITHUB_CLIENT_SECRET
    }),

      </mesh>
    </Canvas>
  )
}
