Using with react

[stevenKirill]

Hello! Can I use this component timeline with React.js library?

[stevenKirill]

I tried to use this library with react and got this error, could anybody help me please?

I guess it's coz of peer dependencies

[RunRanger]

I'm using vis-timeline in my react-project without any problems. Moment.js is just a dependency and hasn't to be listed in your package.json file. It should be installed automatically by vis-timeline itself if you're using a normal packetmangager like npm. Just try to uninstall and install vis-timeline again.

[stevenKirill]

Could you share your code example please? How did you use it in react.js please

[RunRanger]

I just see it now, you have to import from 'vis-timeline/standalone' and not 'vis-timeline'.
if you use any interfaces for typescript you can use 'vis-timeline'.

My code:

import { useRef, useEffect } from "react";
import {
  Timeline as Vis,
  TimelineEventPropertiesResult,
} from "vis-timeline/standalone";
import createOptions from "./createOptions";
import MusicMetaData from "@types/MusicMetaData";

interface Props {
  musicData: MusicMetaData,
  onChangePosition: (positionInPercent: number) => void,
}

function Timeline({ musicData, onChangePosition }: Props) {
  const containerRef = useRef<HTMLDivElement | null>(null);
  const timelineRef = useRef<Vis | null>(null);

  const initTimeline = () => {
    if (!containerRef.current) return;
    timelineRef.current = new Vis(
      containerRef.current,
      [],
      [],
      createOptions({ musicData })
    );
    const timeline = timelineRef.current;
    timeline.addCustomTime(new Date(1920, 0, 1));
    timeline.setCustomTimeTitle("0:0");
    timeline.on("timechange", onTimeChange);
    timeline.on("click", onTimeChange);
  };

  const onTimeChange = (event: TimelineEventPropertiesResult) => {
    const time =
      event.time.getMinutes() * 60 +
      event.time.getSeconds() +
      event.time.getMilliseconds() / 1000;
    onChangePosition((time / musicData.duration) * 100);
  };

  useEffect(() => {
    if (!timelineRef.current) initTimeline();
  }, [containerRef]);

  return <div ref={containerRef} />;
}

export default Timeline;

Great, Could you also send the implementation of createOptions and onChangePosition functions , I would like to understand how does this change your timeline

[RunRanger]

onChangePosition is not relevant for vis or react. It's just a function as property to provide the position of the customMarker to other compontents/outer states.
CreateOptions is just a function which returns the vis-options like you can see in any other sample from offical vis-homepage.

[stevenKirill]

Great, thank you very much) can you show me please the final version if it please?

With this approach, writing and receiving to the state does not work. setState gets when exiting option

[RunRanger]

we can't do anything without exact error message and with the code snippet. We need more to help you.
