I am building a web app on React Js and trying too build a custom map of floors of building. I followed the article on https://www.highcharts.com/docs/maps/create-custom-maps and created an application using HTML CSS and JavaScript,https://jsfiddle.net/hop9cqxj/92/ however I want it inside of ReactJS. Whenever I paste the map options into the React JS variable. I get the error below:
Error
Highcharts error #17: www.highcharts.com/errors/17/?missingModuleFor=map
The demo work's link is here: https://codesandbox.io/s/inspiring-sunset-o3pf92
missingModuleFor: map
You need to use Highmaps source code and mapChart chart constructor type.
import Highcharts from "highcharts/highmaps";
import HighchartsReact from "highcharts-react-official";
import React from "react";
const option2 = {...};
export default function DeltaSecond() {
return (
<>
<HighchartsReact
highcharts={Highcharts}
options={option2}
constructorType="mapChart"
></HighchartsReact>
</>
);
}
Also, I have noticed that Highcharts doesn't work in StrictMode from the newest React, so you can report a potential bug on highcharts-react github: https://github.com/highcharts/highcharts-react

I am trying to impliment Editor.js in my next.js Project but First it was showing the error
Then I searched and get next/dynamic method and loaded the import as dunamic method
And then it is showing this error
Now I have remove the useEffect and initializing the editor and No error is coming , the page is loading normal but the editor is not initialized in the holder "editorjs"
I am trying to impliment editor.js ( Blocked type editor ) to post the blogs in my website .
I had the same issue as you. I added the loading param in the dynamic function and it works.
import dynamic from 'next/dynamic';
const Editor = dynamic(
() => import('#editorjs/editorjs'),
{ssr: false, loading: <p>loading...</p>}
);

I am trying to use Dumbbell chart of highcharts in react app.
As per the link below, I have imported dumbbell module.
https://www.npmjs.com/package/highcharts-react-official#how-to-add-a-module
import highchartsDumbbell from 'highcharts/modules/dumbbell';
import Highcharts from 'highcharts'
import HighchartsReact from 'highcharts-react-official';
highchartsDumbbell(Highcharts);
And wrapping the options and data in HichartsReact component as below:
<HighchartsReact highcharts={Highcharts} options={options} />
Getting below error:
Uncaught TypeError: Cannot read property 'prototype' of undefined
at dumbbell.js:16
at h (dumbbell.js:8)
at dumbbell.js:15
Could you please suggest if anything is missing here.
Notice that the dumbbell series requires also the highcharts-more package.

Another learning project in the works... I am trying to use paperjs in an electron app.
According to the instructions, I think I should be using paper-jsdom (please correct me if I'm wrong). BTW, I am using TypeScript if that makes a difference. I have an HTML document with nothing but an empty <canvas> and a <script> tag referencing this:
import paper, {Color, Point, Path} from 'paper-jsdom'
window.onload = (): void => {
let canvas = document.getElementById("workspace") as HTMLCanvasElement;
paper.setup(canvas);
let path = new Path();
path.strokeColor = Color.random();
let start = new Point(100, 100);
path.moveTo(start);
path.lineTo(start.add(new Point(200, -50)));
paper.view.update();
};
So right off the bat I get:
Uncaught TypeError: paper_jsdom_1.Path is not a constructor
Ugh... So I tried a few random things (it's late, I'm tired...) and changing my import to:
import paper from 'paper'
import {Color, Point, Path} from 'paper-jsdom'
works, or at least the code above works.
Am I supposed to be importing some things from 'paper' and others from 'paper-jsdom'? What is the correct way to use paperjs in an electron app?
Unfortunately paper-jsdom doesn't seem to have any type info for TS.
Thanks!!
Since you are using Paper.js in the renderer process of Electron, you are using it in the browser context and not in Node.js context so you should use the common paper package which relies on browser Canvas API (and not paper-jsdom which targets browserless usage).
So you should be able to use Paper.js as you would for a website.
From your code example, I see that you are using TypeScript so you can have a look at this simple quickstart project that I made to play with Paper.js and TypeScript.
It uses this kind of import:
import * as paper from 'paper';
And then access Paper.js classes through the imported paper object:
new paper.Path.Circle({
center : paper.view.center,
radius : 50,
fillColor: 'orange',
});
Edit
Here is a repository showing the simplest way of using Paper.js in an Electron app.
I have been searching the internet about how to add highchart patternfill in angular highcharts, but no results have been found for angular. Is there any plugin available for angular or anybody have used this in angular application? Thank you.
You need to import and initialize the pattern-fill module:
import * as Highcharts from "highcharts";
import * as patternFill from "highcharts/modules/pattern-fill";
patternFill(Highcharts);

How can import and use any third party javascript libraries in dart..? I want to use snapsvg in my dart application to render svg. But not sure how to add dependencies to add and import it.
I added js: any to my pubspec.yaml and imported packages/browser/interop.js into my html. Where do I place downloaded snapsvg.js and import it to my dart source file to use it.
I am trying to use following javascript code using snapsvg framework from dart.
s = Snap(800, 600);
s.rect(0, 0, 100, 100).attr({
fill: 'white',
stroke: 'black'
});
I tried this code from in dart:
import 'package:js/js.dart' as js;
void main() {
var s = js.context.Snap(800, 600);
s.rect(0, 0, 100, 100);
}
This works fine in dartium, but when I Run as Javascript after build, I got javascript error "method zm not found in object"
I believe this is not right way and I should use be using callMethod on proxy. So I changed code like this
import 'dart:js' show context, JsObject;
void main() {
var snap = context['Snap'];
snap.callMethod('rect', 0,0,100,100);
}
This is not working in Dartium as itself. I would appreciate if someone can provide example of how to call constructor Snap(800, 600) from dart and also rect and attr methods in my example code.
You add them to the HTML file using <script> tags.
You can call JavaScript functions from Dart using dart-js-interop.
There are many examples here on Stackoverflow under this tag - just click on the tag below your question.
When you provide a more concrete example it is easier to help.
You can call into JavaScript with the built-in dart:js library. Please try to avoid using /package/ js, which is what you install by adding js: any to your pubspec. The js package is likely to cause the dart2js output to be bloated and we're probably going to deprecate it at some point.
You can reference JavaScript files like you would in any HTML page, via script tags. You don't actually import them into Dart source, you use dart:js to access JavaScript via its top-level context property.
