Had to rearrange Client/App.js file

[Matthew-Hiebing]

Others might run into this problem so I figured I might as well post the code inside the Client/Apps.js file that I used to get things working.

If you're starting a new React project, you're going to start with a function inside Client/App.js called, App(). This needs to be replaced by Render() and moved into App class. Please see below:

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

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = { apiResponse: "" };
  }

  callAPI() {
      fetch("http://localhost:9000/testAPI")
          .then(res => res.text())
          .then(res => this.setState({ apiResponse: res }));
  }

  componentDidMount() {
      this.callAPI();
  }

  render() {
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <p>
            Edit <code>src/App.js</code> and save to reload.
          </p>
          <a
            className="App-link"
            href="https://reactjs.org"
            target="_blank"
            rel="noopener noreferrer"
          >
            Learn React
          </a>
        </header>
        <p className="App-intro">{this.state.apiResponse}</p>
      </div>
    );
  }
}

export default App;
