为什么在尝试将转译的 js 文件导入我的应用程序时会收到 $ isotafunction 和 window.renderDashboardisnotafunction 的错误？

Question

I have a React Component that uses @nivo/line. I have had no issues working on the component itself, but I am unable to render it in my rails application. I am inserting it into an html.erb.file like this:

<script src="<%=root_url%>DogDashboard.js">    
</script>

index.js of the application I am trying to insert into:

import React from 'react';
import ReactDOM from 'react-dom';
import { Dashboard } from '@reponame/projectrepo';
window.renderDashboard = data =>
    ReactDOM.render(<DogDashboard linedata={data}/>, document.getElementById('name-of-dogdiv'));

App.js of React Component

import React, { Component } from 'react';
import './App.css';


import { Chart } from './components'

class App extends Component {
  render() {
    return (
      <div className="App">
        <header className="App-header">
          <Chart data = {this.props.linedata} />
        </header>
      </div>
    );
  }
}

export default App;

index.js of React Component

import "core-js/stable";
import "regenerator-runtime/runtime";
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import linedata from './linedata.json'

ReactDOM.render(<App linedata={linedata}/>, document.getElementById('name-of-dogdiv'));

serviceWorker.unregister();

The errors I am getting are:

Uncaught TypeError: $ is not a function

                ]

            },
            { 
                test:/\.css/,

            },

        }),
    ],
    resolve: {
        extensions: ['*', '.js'],
    },
    stats: {
        colors: true
    },
    devtool: 'source-map'
}

Things I have tried: * reverse engineering it and specifically seeing where this breaks, but any upgrade I do to the component, breaks the rendering of it. * verified dependencies in package.json * reviewed git history for accidental code changes * limiting the scope of window.renderDashboard * changing the vars to let (even though they would have the same result in my context, but as a sanity check) * adding quotes ( to "”) * removing "window" and making a new global object * removing the lambda and making it a regular function using keyword function in

window.renderDashboard = data => ReactDOM.render(<DogDashboard linedata={data}/>, document.getElementById('name-of-dogdiv'));

Please help. Thanks.

Answer 1

I ended up starting fresh from a new create-react-app and putting my chart over it. I couldn't figure out what was causing this. I am guessing conflicts with dependencies, particularly with core-js. Upgrading dependencies was not helpful.
