## Usage
|
|
|
|
Add `<NuxtLoadingIndicator/>` in your [`app.vue`](/docs/guide/directory-structure/app) or [`layouts/`](/docs/guide/directory-structure/layouts).
|
|
|
|
```vue [app.vue]
|
|
<template>
|
|
<NuxtLoadingIndicator />
|
|
<NuxtLayout>
|
|
<NuxtPage />
|
|

|
```

## Slots
|
|
|
|
You can pass custom HTML or components through the loading indicator's default slot.
|
|
|
|
## Props
|
|
|
|
- `color`: The color of the loading bar. It can be set to `false` to turn off explicit color styling.
|
|
- `errorColor`: The color of the loading bar when `error` is set to `true`.
|
|
- `height`: Height of the loading bar, in pixels (default `3`).
|
|
- `duration`: Duration of the loading bar, in milliseconds (default `2000`).
|
|
- `throttle`: Throttle the appearing and hiding, in milliseconds (default `200`).
|
|
- `estimatedProgress`: By default Nuxt will back off as it approaches 100%. You can provide a custom function to customize the progress estimation, which is a function that receives the duration of the loading bar (above) and the elapsed time. It should return a value between 0 and 100.

::note
|
|
This component is optional. :br
|
|
To achieve full customization, you can implement your own one based on [its source code](https://github.com/nuxt/nuxt/blob/main/packages/nuxt/src/app/components/nuxt-loading-indicator.ts).

|
|
::note
|
|
You can hook into the underlying indicator instance using [the `useLoadingIndicator` composable](/docs/api/composables/use-loading-indicator), which will allow you to trigger start/finish events yourself.
|

|
|
|
|
::tip
|
|
The loading indicator's speed gradually decreases after reaching a specific point controlled by `estimatedProgress`. This adjustment provides a more accurate reflection of longer page loading times and prevents the indicator from prematurely showing 100% completion.
