I'm getting an error type is invalid
when I try to import a stateless component into my App.js to run. When I run the same code in App.js, it works just fine but when I import it, it breaks. What is the solution here and what is going on?
Thank you in advance
my mobile.js
import React from 'react';
//this part will be imported via a component. Need to check and make sure how to update state via component.
const checkIfMobile = {
Android: function() {
return navigator.userAgent.match(/Android/i);
},
BlackBerry: function() {
return navigator.userAgent.match(/BlackBerry/i);
},
iOS: function() {
return navigator.userAgent.match(/iPhone|iPad|iPod/i);
},
Opera: function() {
return navigator.userAgent.match(/Opera Mini/i);
},
Windows: function() {
return navigator.userAgent.match(/IEMobile/i);
},
any: function() {
return (
checkIfMobile.Android() ||
checkIfMobile.BlackBerry() ||
checkIfMobile.iOS() ||
checkIfMobile.Opera() ||
checkIfMobile.Windows()
);
}
};
export default checkIfMobile;
Which is imported into App.js and gives me the type is invalid
error.
import React, { Component } from 'react';
import ChromePluginNotice from '../components/banner/ChromePluginNotice';
import Content from './Content';
import Banner from './Banner';
import Footer from '../components/footer/Footer';
import checkIfMobile from '../components/banner/checks/mobile';
// //this part will be imported via a component. Need to check and make sure how to update state via component.

// Windows: function() {

// any: function() {
// return (
// checkIfMobile.Android() ||
// checkIfMobile.BlackBerry() ||
// checkIfMobile.iOS() ||
// checkIfMobile.Opera() ||
// checkIfMobile.Windows()
// );
// }
// };
export default class App extends Component {
constructor() {
super();
this.state = { isMobile: checkIfMobile.any() };
}
render() {
const { isMobile } = this.state; // destructure isMobile to variable
return (
<div>
<ChromePluginNotice />
<Banner isMobile={isMobile} />
<Content isMobile={isMobile} />
<Footer />
</div>
);
}
}
Not sure what to do to fix it from here. The full error is
invariant.js?4599:44 Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of

StatelessComponent .
这是一些恶意代码试图访问我的 mobile.js 的旧版本,现在一切正常。
