The pages in Next.js are lazy-loaded so if you fetch some API or fetch data from a database it can take a few seconds to reach the second page. So to let the user know that the page is being loaded we will add a progress bar at the top of the screen. Here is how it will look-

So let's get started
Creating a Next app
npx create-next-app next-progress-bar
Installing the required dependency
npm i nextjs-progressbar # npm
yarn add nextjs-progressbar # yarn
Creating the pages (for demo)
First, create a new file in the pages folder. This will create a new route for you.
I am naming it about.js. . I am just creating an h1
tag and a button
that will redirect to the home page.
import Head from "next/head";
import { useRouter } from "next/router";
export default function About() {
const router = useRouter();
return (
<div>
<Head>
<title>Create Next App</title>
<meta name="description" content="Generated by create next app" />
<link rel="icon" href="/favicon.ico" />
</Head>
<h1>About page</h1>
<button onClick={() => router.push("/")}>Go to Home</button>
</div>
);
}
I will do the same in index.js but redirect to the about page instead
import Head from "next/head";
import { useRouter } from "next/router";
export default function Home() {
const router = useRouter();
return (
<div>
<Head>
<title>Create Next App</title>
<meta name="description" content="Generated by create next app" />
<link rel="icon" href="/favicon.ico" />
</Head>
<h1>Home page</h1>
<button onClick={() => router.push("/about")}>Go to about me</button>
</div>
);
}
Adding the progress bar 📊
We will go to _app.js and add the NextNProgress
component
import "../styles/globals.css";
import NextNProgress from "nextjs-progressbar";
function MyApp({ Component, pageProps }) {
return (
<>
<NextNProgress />
<Component {...pageProps} />
</>
);
}
export default MyApp;
And that is it! The progress bar is now working 🥳🎉.
Customizing the progress bar
You can add some props to NextNProgress
like color, height, key, ref, startPosition, and many more. I mostly just change the color and height because I like the other stylings the default way they are. Here is how you can change the color and height-
<NextNProgress height={6} color="#4338C9" />
This will make the progress bar thicker and purple in color. Feel free to try out different colors and styles. Drop your favorite style for the progress bar in the comments 👇🏻

This is really helpful
Hi Avneesh, your project is really cool.
I'm trying to remove the spinner like this but it doesn't work
<NextNProgress options={{ showSpinner: false }} />
this should work. Try restarting your app
Thanks! I restarted the apps as you said and it worked! :D
Really great 👍 I should use it for my next project.
Next Next.js project haha
