blank/white Screen not being rendered-CodePudding

I am getting a blank screen in react app after running it with npm start it worked adequately till yesterday but now it is getting this error and I don't think the code is getting rendered because when I checked the inspect window to enable javascript

App.js

import { useEffect } from "react";
import "./App.css";
import Nav from './Nav.js';

function App() {
  useEffect(() => {
    document.title = "BuildFolks";
  });
}

<Nav />

export default App;

I am also using tailwind css

CodePudding user response：

Your App() function does not return anything, try to make it return <Nav />:

function App() {
  useEffect(() => {
    document.title = "BuildFolks";
  });
  return <Nav />;
}

CodePudding user response：

Your App component is missing the return statement.

import { useEffect } from "react";
import "./App.css";
import Nav from './Nav.js';

function App() {
  useEffect(() => {
   document.title = "BuildFolks";
  });

 return (
    <Nav />
  )

}

export default App;
