Reference

Common Component Props

lineRenderer: ({ index: number, active: boolean, line: Line }) => React.ReactNode

The method to render every valid line of parsed lrc. active means whether it is current line. Line is LrcLine when using Lrc component or is MultipleLrcLine when MultipleLrc.

currentMillisecond?: number

Current time of lrc, default -1.

verticalSpace?: boolean

Make active line always vertical-middle even start or end of line list, default false.

without verticalSpace:

with verticalSpace:

onLineUpdate?: ({ index: number, line: Line | null }) => void

Call this when current line changed. Line is LrcLine when using Lrc component or is MultipleLrcLine when MultipleLrc.

recoverAutoScrollInterval

The interval of recovering auto scroll after user scrolling. It is millisecond, default 5000.

onAutoScrollChange?: ({ autoScroll: boolean }) => void

There is a state which indicates whether or not it is auto-scroll, and which default value is true. When scrolling by user, it will be set to false. After recoverAutoScrollInterval milliseconds, it will be set to true automatically. onAutoScrollChange will be called when the state changed.

Component Lrc

lrc: string

The lrc.

Component MultipleLrc

lrcs: string[]

The lrc array.

Hook useRecoverAutoScrollImmediately

When user scroll, react-lrc will stop auto scroll during recoverAutoScrollInterval. useRecoverAutoScrollImmediately helps recover auto scroll immediately.

import { Lrc, useRecoverAutoScrollImmediately } from 'react-lrc';

const Demo = () => {
  const { signal, recoverAutoScrollImmediately } =
    useRecoverAutoScrollImmediately();

  return (
    <>
      <button type="button" onClick={recoverAutoScrollImmediately}>
        recover auto scroll immediately
      </button>
      <Lrc {...otherProps} recoverAutoScrollSingal={signal} />
    </>
  );
};

Q & A

How to prevent user scroll ?

const style = { overflow: 'hidden !important' };

<Lrc style={style} recoverAutoScrollInterval={0} {...otherProps} />;

How to hide scrollbar ?

.lrc {
  /* webkit */
  &::-webkit-scrollbar {
    width: 0;
    height: 0;
  }

  /* firefox */
  scrollbar-width: none;
}

<Lrc className="lrc" {...otherProps} />
