@im03/react-hls-player

A lightweight, TypeScript-first React component for playing HLS (HTTP Live Streaming) video streams. Built on top of hls.js with full support for React 18 and 19.

---

Features

• Native HLS playback via hls.js with automatic fallback for browsers that support HLS natively (Safari)
• Written in TypeScript with full type exports
• Configurable hls.js options via hlsConfig prop
• Built-in preset system for tuning buffer behavior (performance, balanced, quality)
• Automatic error recovery with exponential backoff retry for network errors
• Imperative handle ref (ReactHlsPlayerRef) for programmatic control: play, pause, seek, volume, quality level
• Supports playerRef for direct access to the underlying <video> element
• Callback props for player lifecycle events: onReady, onPlay, onPause, onEnded, onError, onLevelsLoaded
• Compatible with React 18 and 19
• Zero wrapper overhead — renders a plain <video> element

---

Installation

npm install @im03/react-hls-player hls.js

yarn add @im03/react-hls-player hls.js

pnpm add @im03/react-hls-player hls.js

Peer dependencies: This package requires react and react-dom (v18 or v19) and hls.js to be installed in your project.

Props

Prop	Type	Default	Description
src	string	Required	The URL of the HLS stream (.m3u8 manifest).
playerRef	RefObject<HTMLVideoElement>	—	Ref to the underlying <video> element. Use this for programmatic control.
hlsConfig	HlsConfig	{}	Partial hls.js configuration object. See HlsConfig for available options.
preset	"performance" | "balanced" | "quality"	"balanced"	Buffer preset. See Presets for details.
autoPlay	boolean	false	Whether to start playback automatically. May be blocked by browsers without user interaction.
muted	boolean	true	Whether the video is muted. Set to false to enable audio.
poster	string	undefined	URL of a poster image shown before the video plays.
className	string	""	Additional CSS class name(s). The element always includes react-hls-player as a base class.
onReady	() => void	—	Called when the manifest is parsed and the player is ready.
onPlay	() => void	—	Called when playback starts.
onPause	() => void	—	Called when playback is paused.
onEnded	() => void	—	Called when the video ends.
onError	(error: unknown) => void	—	Called on any hls.js error (fatal or not).
onLevelsLoaded	(levels: string[]) => void	—	Called with a list of human-readable resolution labels (e.g. ["360p", "720p", "1080p"]) when the manifest is parsed.
...props	React.VideoHTMLAttributes<HTMLVideoElement>	—	Any valid HTML <video> attribute is forwarded to the underlying element.

Presets

The preset prop provides opinionated buffer configuration shortcuts. You can still override any value via hlsConfig.

Preset	Description
performance	Small buffer (maxBufferLength: 10, maxMaxBufferLength: 20). Best for low-memory or mobile environments.
balanced	hls.js defaults. Suitable for most use cases.
quality	Large buffer (maxBufferLength: 60, maxMaxBufferLength: 120). Best for VOD where smooth, uninterrupted playback is preferred.

<ReactHlsPlayer
  src="https://example.com/stream.m3u8"
  preset="quality"
  muted={true}
/>

---

Imperative Handle (ReactHlsPlayerRef)

Pass a ref directly to <ReactHlsPlayer> to get access to imperative controls. This is separate from playerRef (which gives access to the raw <video> element).

interface ReactHlsPlayerRef {
  play: () => void;
  pause: () => void;
  seek: (time: number) => void;
  setVolume: (volume: number) => void;   // 0.0 – 1.0
  setQuality: (level: number) => void;   // hls.js level index; -1 for auto
}

import { useRef } from "react";
import { ReactHlsPlayer, ReactHlsPlayerRef } from "@im03/react-hls-player";

export default function Player() {
  const controlRef = useRef<ReactHlsPlayerRef>(null);

  return (
    <>
      <ReactHlsPlayer
        ref={controlRef}
        src="https://example.com/stream.m3u8"
        muted={true}
      />
      <button onClick={() => controlRef.current?.play()}>Play</button>
      <button onClick={() => controlRef.current?.pause()}>Pause</button>
      <button onClick={() => controlRef.current?.seek(30)}>Skip to 0:30</button>
      <button onClick={() => controlRef.current?.setVolume(0.5)}>50% Volume</button>
      <button onClick={() => controlRef.current?.setQuality(0)}>Lowest Quality</button>
    </>
  );
}

---

HlsConfig

The hlsConfig prop accepts a partial configuration object for hls.js. All fields are optional.

type HlsConfig = Partial<{
  autoStartLoad: boolean;
  startPosition: number;
  debug: boolean;
  enableWorker: boolean;
  lowLatencyMode: boolean;
  maxBufferLength: number;
  maxMaxBufferLength: number;
  maxBufferSize: number;
  capLevelToPlayerSize: boolean;
  abrEwmaFastLive: number;
  abrEwmaSlowLive: number;
  abrEwmaFastVoD: number;
  abrEwmaSlowVoD: number;
  enableCEA708Captions: boolean;
  enableWebVTT: boolean;
}>;

For the full list of hls.js configuration options, refer to the hls.js API documentation.

Examples

Autoplay with sound

Note that most browsers block autoplay with audio unless the user has interacted with the page. If autoplay is blocked, a warning is logged to the console instead of throwing an error.

<ReactHlsPlayer
  src="https://example.com/stream.m3u8"
  autoPlay={true}
  muted={false}
/>

With a poster image

<ReactHlsPlayer
  src="http://content.jwplatform.com/manifests/vM7nH0Kl.m3u8"
  poster="https://upload.wikimedia.org/wikipedia/commons/7/7c/Aspect_ratio_16_9_example.jpg"
  muted={true}
/>

Quality switcher using onLevelsLoaded

onLevelsLoaded receives a list of resolution labels derived from the manifest, such as ["360p", "720p", "1080p"]. Use this alongside setQuality on the imperative ref to build a quality selector.

import { useRef, useState } from "react";
import { ReactHlsPlayer, ReactHlsPlayerRef } from "@im03/react-hls-player";

export default function Player() {
  const controlRef = useRef<ReactHlsPlayerRef>(null);
  const [levels, setLevels] = useState<string[]>([]);

  return (
    <>
      <ReactHlsPlayer
        ref={controlRef}
        src="https://example.com/stream.m3u8"
        muted={true}
        onLevelsLoaded={setLevels}
      />
      <select onChange={(e) => controlRef.current?.setQuality(Number(e.target.value))}>
        <option value={-1}>Auto</option>
        {levels.map((label, i) => (
          <option key={i} value={i}>{label}</option>
        ))}
      </select>
    </>
  );
}

Lifecycle callbacks

<ReactHlsPlayer
  src="https://example.com/stream.m3u8"
  muted={true}
  onReady={() => console.log("Player ready")}
  onPlay={() => console.log("Playing")}
  onPause={() => console.log("Paused")}
  onEnded={() => console.log("Ended")}
  onError={(err) => console.error("HLS error", err)}
  onLevelsLoaded={(levels) => console.log("Available qualities:", levels)}
/>

Controlling the player via playerRef

Pass a ref via playerRef to access the native HTMLVideoElement directly.

import { useRef } from "react";
import { ReactHlsPlayer } from "@im03/react-hls-player";

export default function Player() {
  const playerRef = useRef<HTMLVideoElement>(null);

  return (
    <>
      <ReactHlsPlayer
        src="https://example.com/stream.m3u8"
        playerRef={playerRef}
        muted={true}
      />
      <button onClick={() => playerRef.current?.play()}>Play</button>
      <button onClick={() => playerRef.current?.pause()}>Pause</button>
    </>
  );
}

Custom hls.js configuration

<ReactHlsPlayer
  src="https://example.com/stream.m3u8"
  hlsConfig={{
    lowLatencyMode: true,
    maxBufferLength: 30,
    capLevelToPlayerSize: true,
    debug: false,
  }}
  muted={true}
/>

Low-latency live stream

<ReactHlsPlayer
  src="https://example.com/live.m3u8"
  autoPlay={true}
  muted={true}
  preset="performance"
  hlsConfig={{
    lowLatencyMode: true,
    enableWorker: true,
    abrEwmaFastLive: 3,
    abrEwmaSlowLive: 9,
  }}
/>

Forwarding native video attributes

Any standard HTML <video> attribute not listed in the props table is forwarded directly to the video element.

<ReactHlsPlayer
  src="https://example.com/stream.m3u8"
  muted={true}
  width={1280}
  height={720}
  style={{ borderRadius: "8px" }}
  aria-label="Live stream player"
/>

Browser Support

Browser	HLS Support
Chrome	via hls.js
Firefox	via hls.js
Safari	Native (hls.js is bypassed)
Edge	via hls.js
Mobile Safari	Native (hls.js is bypassed)
Android Chrome	via hls.js

When a browser supports HLS natively (e.g., Safari), the component sets the src attribute directly on the <video> element and skips hls.js entirely.

---

Error Handling

The component handles hls.js errors automatically:

• Network errors — retries up to 3 times using hls.startLoad(), with an increasing delay between each attempt (1s, 2s, 3s).
• Media errors — calls hls.recoverMediaError() to attempt recovery.
• Fatal unrecoverable errors — destroys and reinitializes the player from scratch.

All errors are also surfaced via the onError callback if provided.

---

Styling

The rendered <video> element always has the class react-hls-player. You can target it in your stylesheet:

.react-hls-player {
  width: 100%;
  height: auto;
  display: block;
}

You can also pass additional classes via the className prop.

---

TypeScript

All types are exported from the package entry point.

import type {
  ReactHlsPlayerProps,
  ReactHlsPlayerRef,
  HlsConfig,
  PlayerPreset,
} from "@im03/react-hls-player";
