我是 React 的新手,我试图从一个外部文件导入一个 JSON DATA
变量。我得到了以下错误:
找不到模块“ ./customData.json”
有人能帮帮我吗?如果我的 DATA
变量在 index.js
中,但是在外部 JSON 文件中,它就不工作了。
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import customData from './customData.json';
import Profile from './components/profile';
import Hobbies from './components/hobbies';
class App extends Component {
render() {
return (
<div>
<Profile name={this.props.profileData.name}imgUrl={this.props.profileData.imgURL} />
<Hobbies hobbyList={this.props.profileData.hobbyList}/>
</div>
);
}
}
ReactDOM.render(<App profileData={DATA}/>, document.querySelector('.container'));

import React, {Component} from 'react';
var Hobbies = React.createClass({
render: function(){
var hobbies = this.props.hobbyList.map(function(hobby, index){
return (<li key={index}>{hobby}</li>);
});
return (
<div>
<h5>My hobbies:</h5>
<ul>
{hobbies}
</ul>
</div>
);
}
});
export default Hobbies;
配置文件 js
import React from 'react';
var Profile = React.createClass({
render: function(){
return (
<div>
<h3>{this.props.name}</h3>
<img src={this.props.imgUrl} />
</div>
)
}
});
export default Profile
CustomData.json
var DATA = {
name: 'John Smith',
imgURL: 'http://lorempixel.com/100/100/',
hobbyList: ['coding', 'writing', 'skiing']
}
export default DATA
