javascript - Jquery in React is not defined

Question

Hi I just want to receive ajax request, but the problem is that jquery is not defined in React. React version is 14.0

Error message

 Uncaught ReferenceError: $ is not defined

I have two files :

index.js

import React from 'react'; 
import { render } from 'react-dom';
import App from './containers/App';  

const root = document.getElementById('root');  

render( 
  <App source='https://api.github.com/users/octocat/gists' />, 
  root
);

app.js

import React, { Component } from 'react';

export default class App extends Component {

    componentDidMount() {
        const { source } = this.props;

        console.log($); // throws error
    }

    render() {
        return (
            <h1>Hey there.</h1>
        );
    }
}

Try add jQuery to your project, like

npm i jquery --save

or if you use bower

bower i jquery --save

then

import $ from 'jquery';
