Installation

npm i shikwasa2
# or
pnpm i shikwasa2

Also available on CDN: https://www.jsdelivr.com/package/npm/shikwasa

Usage

include stylesheet and script

 <head>
   <link rel="stylesheet" href="shikwasa.min.css">
 </head>
 <body>
   <script src="shikwasa.min.js"></script>
 </body>

If you use module system, import like this instead:

  import 'shikwasa/dist/shikwasa.min.css'
  import Shikwasa from 'shikwasa'

Specify a container to inject the player component.

 <div class="element-of-your-choice">
   <!-- this is where the player will be injected -->
 </div>

Create an instance of the player

 // an example with basic init options

 const player = new Shikwasa({
   container: () => document.querySelector('.element-of-your-choice'),
   audio: {
     title: 'Hello World!',
     artist: 'Shikwasa FM',
     cover: 'image.png',
     src: 'audio.mp3',
   },
 })

Any child nodes inside container will be cleared upon the time Shiwkasa mounts.

Here's a fiddle to kickstart. To use the chapter feature, you need to import the chapter script and stylesheets as well. View details

API

Methods

play

play(): Promise | void

Start playing the current audio. In modern browsers and IE9+ it will return a promise while pre IE9 it will return nothing.

Updating audio via this method is deprecated, use update instead.

pause

pause(): void

Pause the current audio.

toggle

toggle(): Promise | void

Toggle audio play state between play and pause. Promise details.

seek

seek(time: number): void

Seek the audio to the new time. time is a number that specifies target playback time in seconds.

update

update(audio: TAudio): void

Passing TAudio in will replace the current audio source.

  player.update({
    title: 'Embrace the universe with a cup of shikwasa juice',
    artist: 'Shikwasa',
    cover: 'image.png',
    src: 'sourceAudio.mp3'
})

destroy

destroy(): void

Destroy the player instance.

on(event: string, callback: () => void): void

preloadForIOS

preloadForIOS(): void

Even though preload is set as metadata or auto, meta data will not be loaded in iOS devices. You can lead your user to interact (tap / click) with GUI, and then call this function to load meta data.

Properties

currentTime

Read-only
type: number
default: 0

The current playback time. Inherits the native HTMLMediaElement.currentTime.

muted

type: boolean
default: options.muted

The current mute state of the player. Similar to the native HTMLMediaElement.muted, except thatmuted's value will not be affected when audio source is updated.

playbackRate

type: number
default: 1

The current playbackRate of the player. Inherits the native HTMLMediaElement.playbackRate, except thatplaybackRate's value will not be affected when audio source is updated.

duration

type: number
default: audio.duration || options.audio.duration

Options

audio

required
type: TAudio | null
default: null

  TAudio {
    src: string,
    title?: string,
    artist?: string,
    cover?: string,
    duration?: number,
    album?: string,
    live?: boolean,
  }

The target audio to be played. If duration is passed along, players with preload option set to none will be able to display the custom duration in UI before the audio metadata is fetched. However, after the audio metadata is loaded, this prop will be ignored.

album is not visible in the UI. It will only display in the Chrome mini player and any other browsers/devices/operating systems that support MediaSession.

live is for audio stream.

container

(Optional) The container element for the player. If document is not available in the env, pass a function that will return the container element.

type: HTMLElement | () => HTMLElement
default: document.querySelector('body')

fixed

(Optional) Whether player should be fixed to viewport.

type: TFixed

TFixed {
  type: 'auto' | 'fixed' | 'static',
  position: 'bottom' | 'top',
}

default:

{
  type: 'auto',
  position: 'bottom',
}

details:

| Property | Type | Description | |---------------|----------|------------------------------------------| | type | String | either auto, static or fixed auto: player position is controlled by media queries. Normally the player stays static, but on small screens it will be fixed to viewportstatic: force the player to remain static regardless of screen widthfixed: force the player to fix to viewport | | position | String | either bottom or top ⚠️Note: position will be ignored when type is set to static |

themeColor

(Optional) Theme color of the player.

type: string
default: '#00869B'

theme

(Optional)

type: 'auto' | 'dark' | 'light'
default: 'auto'

autoplay

(Optional) If audio should autoplay on load. ⚠️Note: Chrome and Safari disable audio autoplay unless muted is set to true by default. To comply with this policy, see details in Chrome Developers and Webkit Announcement.

type: boolean
default: false

muted

Whether audio should be muted by default. Similar to HTMLMediaElement's defaultMuted.

type: boolean
default: false

preload

(Optional) Choose from auto, metadata and none. For details view MDN Doumentation.

If a parser is used, the audio will be requested immediately on page load for the parser to work properly, even if preload is set to none.

type: 'auto' | 'metadata' | 'none'
default: 'metadata'

speedOptions

(Optional) The playback speed range. Each value of the array should be between the range of 0.25 to 5.0, or will likely be ignored by certain browsers.

type: Array<number>
default: [0.5, 0.75, 1.25, 1.5]

download

(Optional) Whether the current audio source is download-able. When set to true, the player will provide an anchor with downlaod attribute and href set to audio.src. Cross-origin href will not prompt download due to anchor's nature, but you can offer an alternative blob:, data: url or a same-origin direct download link(DDL).

type: string | boolean
default: false
alternatives:

// direct user to the source url
download: true
// direct user to a custom url, preferrably one configured to generate download
download: 'data:audio/mp3;base64,...'

onBeforeClick(target)

点击播放器上的按钮时，执行该回调，若返回 false 则阻断用户该操作

target 有以下值:

play_or_pause: 播放或暂停按钮
mute: 静音按钮
forward: 快进按钮
backward: 后退按钮
speed: 速率调整按钮
seek: 拖动进度条按钮

parser

(Optional) To focus on the player itself as well as to maintain Shikwasa as efficient as possible, we don't extract data from audio files. If you don't have control over the chapter data but would like to implement chapter feature, we support using jsmediatags as an external parser to parse the current audio's metadata.

It will read the audio's title, artist, duration and chapters, meaning you don't have to provide these four properties into audio manually unless you preferred your own. Priority: property values passed to audio > parsed data.

type: null | JSMediatags
default: null
usage:

  npm install jsmediatags // https://github.com/aadsm/jsmediatags

  import jsmediatags from 'jsmediatags'

  new Shikwasa({
    ...
  parser: jsmediatags,
  audio: { src: ... },
  })

⚠️Note: If audio.src is not of the same origin, proper CORS configuration will be needed to use the parser. Due to jsmediatags limitation, relative urls are not supported. Please use absolute urls for audio.src.

Events

Support all HTMLMediaElement native events.

Plus player events:

audioupdate: fired when audio source is updated.

audioparse: fired when audio file data is parsed.

Style

Although Shikwasa have not yet provided a full customization support of its styles, some CSS variables are available and should cover basic needs.

  --background-body                           /* background of the player body */
  --color-title                               /* color of the title text */
  --color-artist                              /* color of the artist text */
  --color-button: var(--color-primary);       /* color of the buttons, defaults to `themeColor` */
  --color-button-disabled                     /* color of button:disabled */
  --color-button-active-background            /* color of the background of button:active` */
  --color-handle: var(--color-primary);       /* color of the playback progress handle, defaults to `themeColor` */
  --color-handle-disabled                     /* color of the handle:disabled */
  --color-bar-loaded                          /* color of the loaded playback progress, defaults to `themeColor` */
  --color-bar-played: var(--color-primary);   /* color of the loaded playback progress, defaults to `themeColor` */
  --color-time                                /* color of the playback time */
  --color-spinner: var(--color-primary);      /* color of the playback loading indicator, defaults to `themeColor` */
  --color-live-symbol: var(--color-primary);  /* color of the live indicator symbol, defaults to `themeColor` */
  --color-live-text: var(--color-primary);    /* color of the live indicator text, defaults to `themeColor` */
  --shadow-body                               /* box shadow of the player body */
  --shadow-body-mobile                        /* box shadow of the player body in small screens */
  --shadow-handle                             /* box shadow of the playback progress handle */
  --shadow-handle-mobile                      /* box shadow of the playback progress handle in small screens */

Usage: overwrite the style property in your player container:

  .container .shk {
    --background-body: linear-gradient(-45deg, #84ccff, #b8e8ff);
  }

Chapters

Shikwasa supports chapters display and playback control with the help of its external chapter plugin. To use this feature:

 import Chapter as 'shikwasa/dist/shikwasa.chapter.cjs'
 import 'shikwasa/dist/shikwasa.chapter.min.css'

 Shikwasa.use(Chapter)
 new Shikwasa({...})

This does not guarantee that the audio will display chapters. To display chapters, you need to provide chapter data to the player.
If you don't have direct access to the chapter data, Shikwasa has built-in support to work with jsmediatags to read and extract the data from the audio file;
- (1) To manually provide chapters, add the chapters property when passing audio into options or .update(audio).
```
  audio: {
    ...
    // manually provide chapters
    chapters: [
      { title, startTime, endTime }, // the first chapter
      { title, startTime, endTime }, // the second chatper
    ],
  }
```
  The structure of a single chapter object:
  | Property | Type | Description | |---------------|----------|------------------------------------------| | title | string | chapter title | | startTime | number | chapter start time in seconds | | endTime | number | chapter end time in seconds |
  ⚠️Note: endTime should be the same as startTime of the next chapter.
- (2) To use an external parser, pass jsmediatags in the parser options. How to use a parser?

(1) will take the higher priority.

Registering Chapter plugin will empower Shikwasa instance with the following API:

Methods:

updateChapter

updateChapter(index: number): void

Seek the audio to the target chapter. index is the index of of chapters array.

Properties:

chapters

<property>

Read-only
type: Array<TChapter> | []
default: []

  TChapter {
    title: string,
    startTime: number,
    endTime: number,
  }

Chapter metadata of the current audio, if any. See Chapter.

currentChapter

Read-only
type: Null | TChapter
default: null

Indicate which chapter is currently on play, if any. See Chapter.

Events:

chapterchange: fired when currentChapter changes.
