javascript - Component names need to start with capital letter? - Stack Overflow

So I am trying to use this as part of my hybrid react app. However when I copy and paste the code into my project it gives me an error

import React, {Component } from 'react';
import { FacebookProvider, Page } from 'react-facebook';
//import {createBottomTabNavigator, createAppContainer} from 'react- 
navigation';
export default class Home extends Component {
    render(){
       //const { navigate } = this.props.navigation
    return (
       <FacebookProvider appId="2319566588264121">
           <Page href="/" tabs="timeline" 
            />
       </FacebookProvider> 
    );
   }
 }

The idea is to have a facebooks pages feed show up on my app screen. However I get this error:

Invariant Violation: View config not found for name div. Make sure to start ponent names with a capital letter.

• Maybe there is something wrong with your configuration. Have you tried github./facebook/create-react-app. It creates you a new project with an example page. It's just one mand and everything should be generated and configured correctly. – Frank Roth Commented Jul 29, 2019 at 13:51

It looks like seeden/react-facebook is built for browsers and the DOM. You cannot use <div> and the likes in React Native -- This means you have to implement this library yourself, or find something else that is React Native patible

Yes,ponents' names must start with capital letter , because , when you write ponent name with small letter , piler runs it like as html tag, but when you write with capital letter , piler runs it from your javascript file location.
