### 🚧 Note to new viewers 🚧

\[90s under-construction gif\]

Thanks for checking out the project! It's in its early stages and currently a mix of protoyping and early structure pointing in the direction we want to go with Video.js v10 (so be kind 🙏).

#### Get up to speed

- Read the [v10 discussion topic](https://github.com/videojs/video.js/discussions/9035)
- Watch [Heff's recent presentation](https://players.brightcove.net/3737230800001/eyILA5XG7K_default/index.html?videoId=6379311036112)
- More roadmap and architecture docs to come...

#### How you can help currently

- Run the React and HTML demos
- Give us feedback in a github issue on:
  - The aesthetics of the player(s)
  - The initial embed code and component structure
  - The general direction

Thank you!

## Quick Start

### HTML / Vanilla JavaScript

```bash
npm install @vjs-10/html
```

```html
<vjs-player src="video.mp4" controls poster="poster.jpg"></vjs-player>
```

### React

```bash
npm install @vjs-10/react
```

```jsx
import { VideoPlayer } from '@vjs-10/react';

<VideoPlayer src="video.mp4" controls poster="poster.jpg" />
```

### React Native

```bash
npm install @vjs-10/react-native
```

```jsx
import { VideoPlayer } from '@vjs-10/react-native';

<VideoPlayer source={{ uri: 'video.mp4' }} controls />
```

## Architecture & Design Philosophy

### Dependency Hierarchy

The monorepo follows a strict dependency hierarchy to ensure modularity and prevent circular dependencies:

```
Core Packages (runtime-agnostic)
    ↓
Platform Packages (HTML, React, React Native)
    ↓
Complete UI Libraries
```

**Rules:**
- **Core packages** have no dependencies on other vjs-10 packages
- **HTML packages** depend only on core packages
- **React packages** depend only on core packages (peer dependency on React)
- **React Native packages** depend only on core packages (peer dependencies on React Native ecosystem)

This ensures:
- Maximum code reusability across platforms
- Clear separation of concerns
- No circular dependencies
- Tree-shakeable, modular architecture

### Key Design Decisions

**State Management** - Built on [nanostores](https://github.com/nanostores/nanostores) for minimal, reactive state that works across all platforms.

**Streaming Support** - HLS.js integration for adaptive bitrate streaming, with extensible design for DASH.js and other engines.

**Web Components** - Standards-based custom elements for HTML/DOM implementation, ensuring framework-agnostic usage.

**TypeScript First** - Full TypeScript support with strict type checking across all packages.

**Accessibility** - WCAG 2.1 AA compliance with keyboard navigation, ARIA attributes, and screen reader support.

## TypeScript

All packages are written in TypeScript and use project references for efficient compilation. The monorepo uses a shared `tsconfig.base.json` for consistent compiler options across all packages.

Key TypeScript features:
- Strict mode enabled with additional checks
- Path mappings for all `@vjs-10/*` packages
- Composite builds for incremental compilation
- Full type definitions included

## Features

- ✅ **HLS Streaming** - Built-in support via HLS.js
- ✅ **Web Components** - Standards-based custom elements
- ✅ **React Integration** - Full React component library
- ✅ **State Management** - Reactive state with nanostores
- ✅ **TypeScript** - Complete type definitions
- ✅ **Accessible** - WCAG 2.1 AA compliant
- ✅ **SSR Ready** - Works with Next.js, Remix, etc.
- ✅ **Tree-shakeable** - Modular architecture
- 🚧 **DASH Streaming** - Coming soon
- 🚧 **React Native** - Coming soon
- 🚧 **Vue Components** - Coming soon
- 🚧 **Svelte Components** - Coming soon
