Introducing the Smart TV

A comprehensive guide to creating professional Smart TV applications with React and TypeScript

If you're building Smart TV apps, you need to check out the Smart TV — a comprehensive monorepo with everything you need to build professional streaming apps. It includes a powerful video player, data fetching utilities, and a CLI to get started in seconds. All open-source and ready to use!

The Problem: Smart TV Development Is Hard

Let me paint you a picture: You're a developer tasked with building a streaming app for Smart TVs. Sounds exciting, right? Until you realize...

🎮 Navigation is completely different — Users navigate with remote controls, not mice or touchscreens
📱 Multiple platforms — Samsung Tizen, LG webOS, Fire TV... each with quirks
🎬 Video playback is complex — Adaptive streaming, DRM, subtitle support, live content
⚡ Performance matters — TV hardware is limited; every KB counts
🔄 Data management — Efficient caching and fetching for smooth experiences

You could spend weeks (or months!) solving these problems from scratch. Or you could use a toolkit that's already solved them.

The Solution: Smart TV

The Smart TV is an open-source monorepo that provides everything developers need to build modern Smart TV applications. Think of it as your development accelerator — it handles the hard parts so you can focus on building great user experiences.

📦 What's Inside?

The toolkit consists of three core packages published on npm:

1. @smart-tv/player 🎬

A production-ready video player built on Shaka Player with:

✅ Adaptive streaming (DASH, HLS)
✅ DRM support (Widevine, PlayReady, FairPlay)
✅ Subtitles and multi-audio tracks
✅ Live and VOD content
✅ Fully customizable UI
✅ TypeScript support

2. @smart-tv/query 🔄

Smart data fetching and caching utilities designed for TV apps:

✅ Automatic caching and revalidation
✅ Infinite scrolling support
✅ Request deduplication
✅ Optimistic updates
✅ Memory-efficient for TV hardware
✅ React hooks for easy integration

3. create-smart-tv-app 🚀

A CLI tool to scaffold complete Smart TV projects:

✅ One command setup
✅ Pre-configured TypeScript, ESLint, Prettier
✅ Tailwind CSS included
✅ Development server ready
✅ Production build optimized

🚀 Getting Started in 30 Seconds

Want to see how easy it is? Here's how you create a complete Smart TV app:

# Create a new app
npm create smart-tv-app my-streaming-app

# Start development
cd my-streaming-app
npm install
npm run dev

That's it! You now have a fully configured Smart TV application with:

TypeScript for type safety
Tailwind CSS for styling
Spatial navigation ready
Hot module reload for fast development
Production builds optimized for TV platforms

💡 Real-World Usage Examples

Let's see the packages in action:

Example 1: Adding a Video Player

import { Player } from '@smart-tv/player';
import '@smart-tv/player/styles.css';

function VideoPage() {
  return (
    <Player
      src="https://example.com/content/manifest.mpd"
      poster="https://example.com/poster.jpg"
      autoPlay={false}
      controls={true}
      onPlay={() => console.log('Playing!')}
      onError={(error) => console.error('Error:', error)}
    />
  );
}

The player handles all the complexity:

Adaptive bitrate streaming
Buffer management
Error recovery
Accessibility features
Cross-platform compatibility

Example 2: Fetching Data Efficiently

import { useQuery } from '@smart-tv/query';

function MovieList() {
  const { data, loading, error, refetch } = useQuery({
    queryKey: ['movies', 'trending'],
    queryFn: async () => {
      const response = await fetch('/api/movies/trending');
      return response.json();
    },
    staleTime: 5 * 60 * 1000, // 5 minutes
    cacheTime: 10 * 60 * 1000, // 10 minutes
  });

  if (loading) return <LoadingSkeleton />;
  if (error) return <ErrorMessage error={error} />;

  return (
    <Grid>
      {data.movies.map((movie) => (
        <MovieCard key={movie.id} movie={movie} />
      ))}
    </Grid>
  );
}

The query hook provides:

Automatic caching
Background refetching
Loading and error states
Request deduplication
Memory efficiency

Example 3: Infinite Scrolling

import { useInfiniteQuery } from '@smart-tv/query';

function BrowseMovies() {
  const {
    data,
    loading,
    error,
    fetchNextPage,
    hasNextPage,
  } = useInfiniteQuery({
    queryKey: ['movies', 'all'],
    queryFn: async ({ pageParam = 1 }) => {
      const response = await fetch(`/api/movies?page=${pageParam}`);
      return response.json();
    },
    getNextPageParam: (lastPage) => lastPage.nextPage,
  });

  return (
    <InfiniteScroll
      onEndReached={fetchNextPage}
      hasMore={hasNextPage}
    >
      {data?.pages.flatMap(page => 
        page.movies.map(movie => (
          <MovieCard key={movie.id} movie={movie} />
        ))
      )}
    </InfiniteScroll>
  );
}

How to play encrypted HLS & DASH play in React with Shaka Player

Faridul Islam — Thu, 05 Oct 2023 12:38:02 +0000

**Shaka Player **is an open-source JavaScript library designed for adaptive media playback. Here are some key points about Shaka Player based on the information gathered from multiple sources:

Media Formats: Shaka Player supports adaptive media formats including Dynamic Adaptive Streaming over HTTP (DASH), Apple's HTTP Live Streaming (HLS), and Microsoft Smooth Streaming (MSS), allowing it to play various media formats in a browser without needing plugins or Flash.
Web Standards: It leverages open web standards such as MediaSource Extensions (MSE) and Encrypted Media Extensions (EME) to facilitate media playback and handling of adaptive bitrate streaming, which dynamically adjusts the quality of a video stream in real-time based on the network conditions.
DRM Services: Shaka Player is notable for its support of Digital Rights Management (DRM) services, which are crucial for content protection. It binds the Video Element and Widevine Content Decryption Module (CDM) by utilizing the EME API to handle adaptive bitrate streaming, ensuring that the quality of the media adapts to the user's bandwidth.
Popularity: It's recognized as the second-most-popular library for media playback, which highlights its reliability and widespread acceptance in the developer community.
Deployment: Shaka Player is designed to be compiled before being deployed, indicating a level of flexibility and control for developers who want to integrate it into their projects.
Maintained by Google: The player is maintained by Google, which suggests a level of credibility and support for the library.

How to use React or Next js

There are lots more packages available on the NPM Packager manager but all of the packages are backdated and there are errors. Also, all packages did not support typescript. So in that case I created a typescript-supported Shaka player for React or Nextjs.
shaka-react-video-player This is best to use for React 16, 17, and 18 versions.

How to use shaka-react-video-player

Installation

npm install shaka-react-video-player --save
yarn add shaka-react-video-player

Usage

import React from 'react';
import ShakaPlayer from 'shaka-react-video-player';
import 'shaka-react-video-player/dist/controls.css';
import 'shaka-react-video-player/dist/themes.css';

function App() {
  return (
    <ShakaPlayer
      autoPlay
      theme="youtube"
      src="https://storage.googleapis.com/shaka-demo-assets/angel-one/dash.mpd"
    />
  );
}

The following ShakaPlayer properties are supported by all of the video tags in HTML:

Property	Description	Type
src	The MPEG-DASH, or HLS media asset. Is provided to `shaka.Player.load` on mount or change.	String
autoPlay	Whether the asset should autoplay or not, directly bound to the `HTMLVideoElement` element.	Boolean
width	Width of the player.	Number
height	Height of the player.	Number
playbackRate	Sets the speed of the audio/video playback.	Number
muted	Sets whether the video is muted or not	Boolean
loop	Sets whether the audio/video should start over again when finished	Boolean
volume	Sets the volume of the audio/video	Number
className	Adds a class to the root element, which is a div.	String
themes	There have 'default, youtube'	String

Note: Follow the npm documentation.

What's needed for improvement?

You guys need to support for this package improvement. Please feel free to contribute to this package.
Here is GitHub: shaka-react-video-player

What issue did I find here?

1. HLS not working without "mux.js"
Dash is working fine but HSL not working without including mux.js.
import muxjs from 'mux.js'; interface MyWindow extends Window { muxjs: string; player: any } (window as MyWindow & typeof globalThis).muxjs = muxjs;
I need to remove this link of code and want it to work perfectly. So please anyone help and contribute there.

2. Typescript Support properly
This package not properly working typescript. Does anyone else work also there?

Please contribute and improve this package for React Lover.
