About NuxtLoadingIndicator

I want to ask you guys about nuxtloadingindicator when switching pages. I want to show that. How can i make that happen to show? (ex. const nuxtapp = useNuxtapp(); after that i will use hooks that page:loading:start and end to handle start and finished functions from useLoadingIndictor util. I am using that method but didn't work.)

Hi @NyiNyi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To implement the NuxtLoadingIndicator for page transitions in Nuxt 3, you can follow these steps: 1. First, add the <NuxtLoadingIndicator /> component to your app.vue file: 
<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
This will automatically display the loading indicator between page navigations NuxtLoadingIndicator docs (https://nuxt.com/docs/api/components/nuxt-loading-indicator#usage). 2. If you want more control over the loading indicator, you can use the useLoadingIndicator composable. Here's an example of how to use it: 
<script setup lang="ts">
const { isLoading, progress, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  start()
})

nuxtApp.hook('page:finish', () => {
  finish()
})
</script>

<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
<script setup lang="ts">
const { isLoading, progress, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  start()
})

nuxtApp.hook('page:finish', () => {
  finish()
})
</script>

<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
This approach uses the page:start and page:finish hooks to control the loading indicator useLoadingIndicator docs (https://nuxt.com/docs/api/composables/use-loading-indicator#example). Note that the page:loading:start and page:loading:end hooks you mentioned are not the correct hooks for this purpose. The correct hooks are page:start and page:finish Nuxt Lifecycle Hooks (https://nuxt.com/docs/api/advanced/hooks). If you're still having issues, make sure that: 1. You're using Nuxt 3. 2. The <NuxtLoadingIndicator /> component is placed in your app.vue file or in a layout that wraps all your pages. 3. You're not accidentally stopping the loading indicator prematurely in your code. If you need to customize the appearance of the loading indicator, you can pass props to the <NuxtLoadingIndicator /> component: 
<NuxtLoadingIndicator :height="5" color="#00dc82" />
<NuxtLoadingIndicator :height="5" color="#00dc82" />
This will adjust the height and color of the loading bar NuxtLoadingIndicator Props (https://nuxt.com/docs/api/components/nuxt-loading-indicator#props). Remember that the loading indicator is designed to work automatically with Nuxt's page transitions. If you're not seeing it, ensure that you're actually navigating between different pages in your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize that you're still experiencing issues with the NuxtLoadingIndicator. To better assist you, could you please provide more specific details about the problem you're facing? For example: 1. Are you not seeing the loading indicator at all? 2. Is it appearing but not behaving as expected? 3. Are you encountering any error messages in the console? Without more information about your specific issue, it's difficult to provide a targeted solution. If you can share more details about your setup and the exact behavior you're observing, I'd be happy to help you troubleshoot further. Remember, the NuxtLoadingIndicator is designed to work automatically in most cases, but there can be situations where additional configuration or debugging is needed. If you can provide a minimal code example or describe your current implementation, that would be very helpful in identifying the root cause of your issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're not seeing the loading indicator at all. Let's troubleshoot this issue step by step: 1. First, make sure you have added the <NuxtLoadingIndicator /> component to your app.vue file or your default layout. It should look something like this: 
<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
<template>
  <div>
    <NuxtLoadingIndicator />
    <NuxtPage />
  </div>
</template>
NuxtLoadingIndicator docs (https://nuxt.com/docs/api/components/nuxt-loading-indicator#usage) 2. If you've added the component but still don't see it, it's possible that the loading is happening too quickly for you to notice. You can try adding a throttle to slow it down: 
<NuxtLoadingIndicator :throttle="500" />
<NuxtLoadingIndicator :throttle="500" />
This will add a 500ms delay before the loading indicator appears, making it more noticeable NuxtLoadingIndicator Props (https://nuxt.com/docs/api/components/nuxt-loading-indicator#props). 3. Another possibility is that the loading indicator is appearing but is not visible due to styling issues. Try increasing its height and changing its color to make it more prominent: 
<NuxtLoadingIndicator :height="5" color="#ff0000" />
<NuxtLoadingIndicator :height="5" color="#ff0000" />
4. If you're using a custom implementation with useLoadingIndicator, make sure you're calling the start() and finish() functions correctly: 
<script setup>
const { start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()
nuxtApp.hook('page:start', () => {
  start()
})
nuxtApp.hook('page:finish', () => {
  finish()
})
</script>
<script setup>
const { start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()
nuxtApp.hook('page:start', () => {
  start()
})
nuxtApp.hook('page:finish', () => {
  finish()
})
</script>
useLoadingIndicator docs (https://nuxt.com/docs/api/composables/use-loading-indicator) 5. Ensure that you're actually navigating between different pages in your application. The loading indicator only appears during page transitions. 6. Check your browser console for any error messages that might indicate why the loading indicator isn't appearing. 7. If you're running your app in development mode, try building and running it in production mode to see if the issue persists: 
npm run build
npm run start
npm run build
npm run start
If none of these steps resolve your issue, it might be helpful to create a minimal reproduction of the problem in a fresh Nuxt 3 project. This can help isolate whether the issue is specific to your project configuration or if it's a potential bug in Nuxt itself. If you're still unable to see the loading indicator after trying these steps, please provide more details about your Nuxt version, project setup, and any custom configurations you might have that could be affecting the loading indicator. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I call start function in page start and console.log(isLoading.value) the value is false @kapa.ai

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information you've provided, it seems that there might be an issue with how the isLoading state is being updated or accessed. Let's investigate this further: 1. First, make sure you're using the useLoadingIndicator composable correctly. Here's how it should be implemented: 
<script setup>
const { isLoading, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  start()
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  finish()
  console.log('isLoading after finish:', isLoading.value)
})
</script>
<script setup>
const { isLoading, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  start()
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  finish()
  console.log('isLoading after finish:', isLoading.value)
})
</script>
useLoadingIndicator docs (https://nuxt.com/docs/api/composables/use-loading-indicator) 2. If you're still seeing false immediately after calling start(), it's possible that the state update is not synchronous. Try wrapping your console.log in a nextTick: 
<script setup>
import { nextTick } from 'vue'

// ... other code ...

nuxtApp.hook('page:start', async () => {
  start()
  await nextTick()
  console.log('isLoading after start:', isLoading.value)
})
<script setup>
import { nextTick } from 'vue'

// ... other code ...

nuxtApp.hook('page:start', async () => {
  start()
  await nextTick()
  console.log('isLoading after start:', isLoading.value)
})
3. Another possibility is that the page:start hook is being called multiple times, or that finish() is being called immediately after start(). To debug this, you can add more logging: 
<script setup>
const { isLoading, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  console.log('page:start hook triggered')
  start()
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  console.log('page:finish hook triggered')
  finish()
  console.log('isLoading after finish:', isLoading.value)
})
</script>
<script setup>
const { isLoading, start, finish } = useLoadingIndicator()

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  console.log('page:start hook triggered')
  start()
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  console.log('page:finish hook triggered')
  finish()
  console.log('isLoading after finish:', isLoading.value)
})
</script>
4. It's worth noting that the isLoading state might be affected by Nuxt's hydration process. If you're checking this value during the initial page load, you might want to ensure that the app has finished hydrating: 
<script setup>
const nuxtApp = useNuxtApp()

if (process.client) {
  nuxtApp.hook('app:mounted', () => {
    console.log('App has finished hydrating')
    // Your loading indicator logic here
  })
}
</script>
<script setup>
const nuxtApp = useNuxtApp()

if (process.client) {
  nuxtApp.hook('app:mounted', () => {
    console.log('App has finished hydrating')
    // Your loading indicator logic here
  })
}
</script>
useNuxtApp docs (https://nuxt.com/docs/api/composables/use-nuxt-app#ishydrating) 5. If none of the above solutions work, there might be an issue with how the useLoadingIndicator composable is implemented in your Nuxt version. You can try creating a custom loading state as a workaround: 
<script setup>
import { ref } from 'vue'

const isLoading = ref(false)

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  isLoading.value = true
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  isLoading.value = false
  console.log('isLoading after finish:', isLoading.value)
})
</script>
<script setup>
import { ref } from 'vue'

const isLoading = ref(false)

const nuxtApp = useNuxtApp()

nuxtApp.hook('page:start', () => {
  isLoading.value = true
  console.log('isLoading after start:', isLoading.value)
})

nuxtApp.hook('page:finish', () => {
  isLoading.value = false
  console.log('isLoading after finish:', isLoading.value)
})
</script>
If you're still experiencing issues after trying these suggestions, it would be helpful to see more of your code, including how you're using the <NuxtLoadingIndicator> component and any other relevant parts of your application. This would allow for a more accurate diagnosis of the problem. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
