The next-nprogress-bar and nprogress-v2 packages remain available and usable in their current versions, but will no longer be maintained. We therefore advise you to migrate to @bprogress/next.

Getting started

$3

``bash
npm install next-nprogress-bar
`

or

`bash
yarn add next-nprogress-bar
`

$3

_Import it into your /pages/\_app(.js/.jsx/.ts/.tsx) or /app/layout(.js/.jsx/.ts/.tsx) folder_

`javascript
// In app directory
import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

// In pages directory
import { PagesProgressBar as ProgressBar } from 'next-nprogress-bar';
`

$3

`javascript

`

Example with /pages/\_app

$3

`jsx
import { PagesProgressBar as ProgressBar } from 'next-nprogress-bar';

export default function App({ Component, pageProps }) {
return (
<>

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>

);
}
`

$3

`tsx
import type { AppProps } from 'next/app';
import { PagesProgressBar as ProgressBar } from 'next-nprogress-bar';

export default function App({ Component, pageProps }: AppProps) {
return (
<>

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>

);
}
`

Example with /app/layout

$3

#### First approach in a use client layout

`jsx
// In /app/layout.jsx
'use client';

import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

export default function RootLayout({ children }) {
return (


{children}
height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>


);
}
`

#### Second approach wrap in a use client Providers component

See Next.js documentation

##### /components/ProgressBarProvider.jsx

`jsx
// Create a Providers component to wrap your application with all the components requiring 'use client', such as next-nprogress-bar or your different contexts...
'use client';

import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

const Providers = ({ children }) => {
return (
<>
{children}
height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>

);
};

export default Providers;
`

##### /app/layout.jsx

`jsx
// Import and use it in /app/layout.jsx
import Providers from './providers';

export const metadata = {
title: 'Create Next App',
description: 'Generated by create next app',
};

export default function RootLayout({ children }) {
return (


{children}


);
}
`

#### First approach in a use client layout

// In /app/layout.tsx
'use client';

import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

export default function RootLayout({
children,

children: React.ReactNode;
}) {
return (


{children}
height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>


);
}

import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

const Providers = ({ children }: { children: React.ReactNode }) => {

Data attributes

$3

You can disable the progress bar on specific links by adding the data-disable-nprogress={true} attribute.

_/!\ This will not work for Link in svg elements._

`jsx

Features

`

$3

You can prevent the progress bar from starting by adding the data-prevent-nprogress={true} attribute.

`jsx

Dashboard
e.preventDefault()} data-prevent-nprogress={true}>
preventDefault


`

Props

$3

Height of the progress bar - by default 2px

$3

Color of the progress bar - by default #0A2FFF

$3

by default undefined

See NProgress V2 docs

$3

Position of the spinner (if showSpinner is true) - by default top-right

$3

Do not display the progress bar when the query parameters change but the route remains the same - by default false

See Next.js docs

$3

The position the progress bar starts at from 0 to 1 - by default 0

$3

When the page loads faster than the progress bar, it does not display - by default 0

$3

Disable the progress bar when the target URL is the same as the current URL - by default true

$3

The delay in milliseconds before the progress bar stops - by default 0

$3

A cryptographic nonce (number used once) used to declare inline scripts for Content Security Policy - by default undefined

$3

A cryptographic nonce (number used once) used to declare inline scripts for Content Security Policy - by default true

$3

Your custom CSS - by default NProgress CSS

$3

Disable the default CSS - by default false
If you need to disable the default CSS, you will need to add your own CSS to see the progress bar. You can use NProgress CSS as a base.

$3

Activates a detailed comparison of component props to determine if a rerender is necessary.
When true, the component will only rerender if there are changes in key props such as color, height, shallowRouting, delay, options, and style.
This is useful for optimizing performance in scenarios where these props change infrequently. If not provided or set to false, the component will assume props have not changed and will not rerender, which can enhance performance in scenarios where the props remain static. - by default undefined

$3

Provides a custom function to preprocess the target URL before comparing it with the current URL.
This is particularly useful in scenarios where URLs undergo transformations, such as localization or path modifications, after navigation.
The function takes a URL object as input and should return a modified URL object.
If this prop is provided, the preprocessed URL will be used for comparisons, ensuring accurate determination of whether the navigation target is equivalent to the current URL.
This can prevent unnecessary display of the progress bar when the target URL is effectively the same as the current URL after preprocessing. - by default undefined

$3

Start the progress bar on load - by default false

App directory router

$3

`jsx
import { useRouter } from 'next-nprogress-bar';
`

$3

`tsx
router.push(url: string, options?: NavigateOptions, NProgressOptions?: RouterNProgressOptions)
router.replace(url: string, options?: NavigateOptions, NProgressOptions?: RouterNProgressOptions)
router.back(NProgressOptions?: RouterNProgressOptions)
router.refresh(NProgressOptions?: RouterNProgressOptions)
`

NavigateOptions is the options of the next router.

`tsx
interface RouterNProgressOptions {
showProgressBar?: boolean;
startPosition?: number;
disableSameURL?: boolean;
}
`

$3

Replace your 'next/navigation' routers with this one. It's the same router, but this one supports NProgress.

`tsx
const router = useRouter();

// With progress bar
router.push('/about');
router.replace('/?counter=10');
router.back();
router.refresh();
`

It also has an optional parameter (customRouter) that allows you to use this router with another custom router (for example, it could be the one from next-intl):

`tsx
import { useRouter as useAnotherCustomRouter } from 'sample-package';
const router = useRouter(useAnotherCustomRouter);

// With progress bar
router.push('/about');
router.replace('/?counter=10');
router.back();
router.refresh();
`

Migrating from v1 to v2

$3

`jsx
// before (v1)
import ProgressBar from 'next-nprogress-bar';

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>;

// after (v2)
import { PagesProgressBar as ProgressBar } from 'next-nprogress-bar';

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>;
`

$3

`jsx
// before (v1)
import ProgressBar from 'next-nprogress-bar';

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
appDirectory
shallowRouting
/>;

// after (v2)
import { AppProgressBar as ProgressBar } from 'next-nprogress-bar';

height="4px"
color="#fffd00"
options={{ showSpinner: false }}
shallowRouting
/>;
``
