⏯ Dumb and (re)useful React components for media players.
react-player-controls
This is a minimal set of modular and hopefully useful React components for composing media player interfaces. It is designed for you to compose media player controls yourself using a small and easy-to-learn API.
Instead of shipping default but customisable styles, there are implementation recipies to help you get going quickly. Also check out the demo site to try the components out.
⚠️ NOTE: This library does not deal with actual media in any way, only the UI. ⚠️

<PlayerIcon />

<Slider />
Direction
An enum describing a slider's active axis.
Key | Value |
---|---|
HORIZONTAL |
"HORIZONTAL" |
VERTICAL |
"VERTICAL" |
<FormattedTime />
<FormattedTime />
translates a number of seconds into the player-friendly format of m:ss
, or h:mm:ss
if the total time is one hour or higher.
// This will render -1:01:02
<FormattedTime numSeconds={-3662} />
Prop name | Default value | Description |
---|---|---|
numSeconds |
0 |
A number of seconds, positive or negative |
className |
null |
A string to set as the HTML class attribute |
style |
{} |
Styles to set on the wrapping span element. |
<PlayerIcon />
<PlayerIcon />
is not really a component in itself, but a container of a number of icon components.
<PlayerIcon.Play />
<PlayerIcon.Pause />
<PlayerIcon.Previous />
<PlayerIcon.Next />
<PlayerIcon.SoundOn />
<PlayerIcon.SoundOff />
Any props passed to a <PlayerIcon.* />
component will be passed onto the underlying svg
element.
<Slider />
The <Slider />
helps you build things like volume controls and progress bars. It does not take a value
prop, but expects you to keep track of this yourself and render whatever you want inside it.
What this component actually does is that it renders an element inside itself, on top of its children, which listens to mouse events and invokes change and intent callbacks with relative, normalised values based on those events.
<Slider
direction={Direction.HORIZONTAL}
onIntent={intent => console.log(`hovered at ${intent}`)}
onIntentStart={intent => console.log(`entered with mouse at ${intent}`)}
onIntentEnd={() => console.log('left with mouse')}
onChange={newValue => console.log(`clicked at ${newValue}`)}
onChangeStart={startValue => console.log(`started dragging at ${startValue}`)}
onChangeEnd={endValue => console.log(`stopped dragging at ${endValue}`)}
>
{/* Here we render whatever we want. Nothings is rendered by default. */}
</Slider>
Prop name | Default value | Description |
---|---|---|
direction |
Direction.HORIZONTAL |
The slider's direction |
onIntent |
(intent) => {} |
A function that is invoked with the relative, normalised value at which the user is hovering (when not dragging). |
onIntentStart |
(intent) => {} |
A function this is invoked with the relative, normalised value at which the user started hovering the slider (when not dragging). |
onIntentEnd |
() => {} |
A function this is invoked when the mouse left the slider area (when not dragging). |
onChange |
(value) => {} |
A function that is invoked with the latest relative, normalised value that the user has set by either clicking or dragging. |
onChangeStart |
(value) => {} |
A function that is invoked with the relative, normalised value at which the user started changing the slider's value. |
onChangeEnd |
(value) => {} |
A function that is invoked with the relative, normalised value at which the user stopped changing the slider's value. When the component unmounts, this function will be invoked with a value of null . |
children |
null |
Child elements. |
className |
null |
A string to set as the HTML class attribute. |
style |
{} |
Styles to set on the wrapping div element. |
overlayZIndex |
10 | The z-index of the invisible overlay that captures mouse events |

Styled buttons with icons
import { PlayerIcon } from 'react-player-controls'
// A base component that has base styles applied to it

const PreviousButton = props => <button {...props}><PlayerIcon.Previous /></button>

Styled slider
import { Direction, Slider } from 'react-player-controls'
const WHITE_SMOKE = '#eee'

Playback controls

Progress bar with buffer

Progress bar that shows the target time on hover

handleIntentEnd() {
// Note that this might not be invoked if the user ends
// a control change with the mouse outside of the slider
// element, so you might want to do this inside a
// onChangeEnd callback too.
