Hi @formal monolith. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, there isn't a direct solution to your problem. However, I can suggest a few things that might help.

  1. Lazy Loading: You can use Next.js's dynamic import feature to lazy load your video component. This means the video will only be loaded when it's needed, which could help improve the initial load time of your page. Here's an example of how to do this:
import dynamic from 'next/dynamic'

const PageLoading = dynamic(() => import('../components/PageLoading'), {
  loading: () => <p>Loading...</p>,
})

export default function Page() {
  return (
    <div>
      <PageLoading />
    </div>
  )
}

Source (https://nextjs.org/docs/app/building-your-application/optimizing/lazy-loading)

  1. Client-side Rendering: If the delay is due to the time it takes to download, parse, and execute JavaScript, you might want to consider using client-side rendering for your page. This means the page will be rendered in the browser using JavaScript, which can be faster than server-side rendering. Here's an example of how to do this:
import React, { useState, useEffect } from 'react'

export function Page() {
  const [data, setData] = useState(null)

  useEffect(() => {
    const fetchData = async () => {
      const response = await fetch('<https://api.example.com/data'>)
      if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`)
      }
      const result = await response.json()
      setData(result)
    }

    fetchData().catch((e) => {
      console.error('An error occurred while fetching the data: ', e)
    })
  }, [])

  return <p>{data ? `Your data: ${data}` : 'Loading...'}</p>
}

  1. Streaming: If you're using Next.js 13 or later, you can use the loading file convention or a Suspense component to show an instant loading state from the server while the content of a route segment loads. This could help improve the perceived load time of your page. Here's an example of how to do this:
import { Suspense } from 'react'
import { PostFeed, Weather } from './components'

export default function Posts() {
  return (
    <section>
      <Suspense fallback={<p>Loading feed...</p>}>
        <PostFeed />
      </Suspense>
      <Suspense fallback={<p>Loading weather...</p>}>
        <Weather />
      </Suspense>
    </section>
  )
}

@ancient pier No video should be already present when I render PageLoading component. now PageLoading component starts loading the video after it is rendered, so i see the yellow circle background, then the video appears. I want that video appears directly when PageLoading component renders

Based on the information provided in the extracts, there isn't a direct solution to your problem. However, I can suggest a few things that might help.

  1. Preloading the Video: You can try preloading the video so that it's ready to play as soon as the PageLoading component is rendered. This can be done by adding the preload attribute to your video tag:
<video autoPlay loop muted playsInline preload="auto">
  <source
    src={{absoluteUrl("/loading/loading.webm")}}
    type="video/webm"
  />
  <source src={{absoluteUrl("/loading/loading.mp4")}} type="video/mp4" />
</video>

The preload attribute hints to the browser that you expect the user to need this video and it should start getting loaded as soon as possible. The auto value allows the browser to decide whether to load the video immediately (based on factors like connection speed and whether the user interacts with the video).

Please note that preloading can consume significant bandwidth, so use it judiciously.

  1. Using a Poster Image: Another approach could be to use a poster image that will be displayed before the video starts playing. This can be done by adding the poster attribute to your video tag:
<video autoPlay loop muted playsInline poster="/path/to/poster.jpg">
  <source
    src={{absoluteUrl("/loading/loading.webm")}}
    type="video/webm"
  />
  <source src={{absoluteUrl("/loading/loading.mp4")}} type="video/mp4" />
</video>

The poster attribute specifies an image to be shown while the video is downloading, or until the user hits the play button.

Please note that these are general suggestions and might not directly solve your problem. You might need to adjust them to fit your specific use case.

@ancient pier How can I make this component shows preloaded and prerendered, so it just shows instantly

@ancient pier can I cache this JSX.Element and use cached Element?

Let me check the knowledge base for you. One moment! :books:

Based on the information provided in the extracts, there isn't a direct solution to your problem. However, I can suggest a few things that might help.

Caching a JSX.Element directly is not a common practice in React or Next.js. The reason is that React components (which are essentially JSX.Elements) are not just static HTML - they can have state, effects, and can re-render when props change. Caching a component instance would mean freezing all of this, which is generally not what you want.

However, Next.js does provide several caching mechanisms to improve your application's performance:

  1. Server-side Caching: Next.js caches the result of server-side rendering, which can significantly improve performance for subsequent requests. This is done automatically by Next.js and doesn't require any configuration. Source (https://nextjs.org/docs/app/building-your-application/caching)

  2. Incremental Static Regeneration (ISR): With ISR, you can create a static page at build time, but update it incrementally as new requests come in. This allows you to have a fast, static page that can still be updated with new data over time. Source (https://nextjs.org/docs/app/building-your-application/caching)

  3. Client-side Caching: For data fetching on the client side, you can use libraries like SWR or React Query, which provide built-in caching mechanisms. Source (https://nextjs.org/docs/pages/building-your-application/rendering/client-side-rendering)

Remember, these are general suggestions and might not directly solve your problem. You might need to adjust them to fit your specific use case.
