Getting white screen on running npm start in my react js project
Question
So is <strictmode causing this problem ??? 2 I am getting a white screen while i am trying to run npm start . The npm start works but I am getting a white screen on http://localhost:3000/ . I tried to add {"homepage": ".",} to my index.html file ,still i am getting the same error ? Could you please tell me where i am doing things wrong ? Also i tried to debug it through google console but it shows nothing.
index.html file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href=" https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

manifest.json provides metadata used when your web app is installed on a

Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
