highcharts/highcharts-react-native

Is there anyway to use this library in a project which is initialized by Expo & using Typescript template?

I know this library is deprecated but hope someone has also met the issue.
I tried following the instruction but it doesn't work.

My steps:

  • Install package by yarn
  • Create file metro.config.js
  • Install react-native-webview by yarn
  • Put some //@ts-ignore in code for ignore type checking
  • Try with the example code in a component
import React, { useEffect, useState } from "react";
import { View, StyleSheet } from "react-native";
// @ts-ignore
import HighchartsReactNative from "@highcharts/highcharts-react-native";

const Chart: React.FC = () => {
  const [chartOptions, setChartOptions] = useState<any>();

  useEffect(() => {
    let intervalId: NodeJS.Timer;
    const chartOptionsTest = {
      chart: {
        events: {
          load: function () {
            // @ts-ignore
            // set up the updating of the chart each second
            const series = this.series[0];
            intervalId = setInterval(function () {
              const y = Math.random();
              series.addPoint(y, true, true);
            }, 1000);
          }
        }
      },
      series: [{
        data: [1, 2, 3]
      }]
    }
    setChartOptions(chartOptionsTest);

    return () => {
      if (intervalId) {
        clearInterval(intervalId);
      }
    }
  }, [])

  return (
    <View style={styles.container}>
      <HighchartsReactNative
        styles={styles.container}
        options={chartOptions}
      />
    </View>
  )
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: '#fff',
    justifyContent: 'center',
    flex: 1
  }
});

export default Chart;

what is the error?

what is the error?

The chart doesn't show up although there isn't any error.
I just wonder if there is anyone has used this library with the typescript template which is created by Expo CLI? or it doesn't work because it doesn't support typescript so we can close this issue.

Can you inspect the webview? maybe there is an error there.

Had tough time using the package. So went about custom approach using WebView.

I'm new here can you make a demo. That will be great. 👍
