title: manifest.json
description: API Reference for manifest.json file.
---
Add or generate a `manifest.(json|webmanifest)` file that matches the [Web Manifest Specification](https://developer.mozilla.org/docs/Web/Manifest) in the **root** of `app` directory to provide information about your web application for the browser.
## Static Manifest file
```json filename="app/manifest.json | app/manifest.webmanifest"
{
"name": "My Next.js Application",
"short_name": "Next.js App",
"description": "An application built with Next.js",
"start_url": "/"
// ...
}
```
## Generate a Manifest file
Add a `manifest.js` or `manifest.ts` file that returns a [`Manifest` object](#manifest-object).
> Good to know: `manifest.js` is special Route Handlers that is cached by default unless it uses a [Dynamic API](/docs/app/guides/caching#dynamic-apis) or [dynamic config](/docs/app/guides/caching#segment-config-options) option.
```ts filename="app/manifest.ts" switcher
import type { MetadataRoute } from 'next'
export default function manifest(): MetadataRoute.Manifest {
return {
name: 'Next.js App',
short_name: 'Next.js App',
description: 'Next.js App',
start_url: '/',
display: 'standalone',
background_color: '#fff',
theme_color: '#fff',
icons: [
{
src: '/favicon.ico',
sizes: 'any',
type: 'image/x-icon',
},
],
}
}
```
```js filename="app/manifest.js" switcher
export default function manifest() {
return {
name: 'Next.js App',
short_name: 'Next.js App',
description: 'Next.js App',
start_url: '/',
display: 'standalone',
background_color: '#fff',
theme_color: '#fff',
icons: [
{
src: '/favicon.ico',
sizes: 'any',
type: 'image/x-icon',
},
],
}
}
```
### Manifest Object
The manifest object contains an extensive list of options that may be updated due to new web standards. For information on all the current options, refer to the `MetadataRoute.Manifest` type in your code editor if using [TypeScript](https://nextjs.org/docs/app/api-reference/config/typescript#ide-plugin) or see the [MDN](https://developer.mozilla.org/docs/Web/Manifest) docs.
