Created changes in my react app to update favicon. After deploying on Aws CodePipeline, i get a blank page. However this is not the case in incognito mode.
This is my index.html file found in the public folder
** I commented out link to favicon and manifest.json
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<!-- <link rel="icon" href="%PUBLIC_URL%/favicon.svg" /> -->
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta name="description" content="Web site created using create-react-app" />
<!-- <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" /> -->
<!--
manifest.json provides metadata used when your web app is installed on a
user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
-->
<!-- <link rel="manifest" href="%PUBLIC_URL%/manifest.json" /> -->
<!--
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`.

here's the link to my GH page
https://filipdimko11.github.io/crypto-tracker/
When running it locally, the project renders everything. After hosting it on GH pages, though, the website doesn't render anything (no errors in the console either).
I tried making an empty commit, saw it as another solution on StackOverflow, but that didn't fix it. Using ReactJS, thanks.
The problem is because in your index.html file you are referencing your assets like /static/js/main.2227a53b.js which makes sense when you are running locally.
But when you deploy to github pages, the directory structure is different. To make it work properly you'd need the routes to be prefixed with crypto-tracker/ For example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<meta name="theme-color" content="#000000" />
<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
<link
href="https://fonts.googleapis.com/css2?family=Roboto&display=swap"
rel="stylesheet"
/>
<meta name="description" content="Your best crypto tracker!" />
<link rel="manifest" href="/manifest.json" />
<title>Crypto Tracker</title>
<script defer="defer" src="crypto-tracker/static/js/main.2227a53b.js"></script>
<link href="crypto-tracker/static/css/main.f53fb378.css" rel="stylesheet" />
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
Depending on what build tool you are using, this is probably configurable.
I am converting an existing bootstrap theme to react js. Having copied the required folders (css, fonts, images, and js) into react public folder, and add the link to each files into public/index.html file as seen below;
<!-- public/index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
<meta name="description" content="Web site created using create-react-app" />
<link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
<link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<link rel="stylesheet" href="%PUBLIC_URL%/fonts/flaticon/flaticon.css">

</html>
It appears that the css files in the head session work correctly except for the js files in the body session. After inspecting the page for error via browser, i found this..
DevTools failed to load source map: Could not load content for http://localhost:3000/css/vendor/bootstrap.min.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
DevTools failed to load source map: Could not load content for http://localhost:3000/js/vendor/popper.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
DevTools failed to load source map: Could not load content for http://localhost:3000/js/vendor/bootstrap.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
How can i fix this as nothing seem to be working after several attempt including disable/enable javascript/css from browser inspect -> settings (gear) as well as using npm install bootstrap jquery popper.js
I am having a react app. At the time of build generation, in my build folder I am getting below code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" href="/favicon.ico" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta name="description" content="Web site created using create-react-app" />
<link rel="apple-touch-icon" href="/logo192.png" />
<link rel="manifest" href="/manifest.json" />
<title>React App</title>
<script defer="defer" src="/static/js/main.8d8de8a8.js"></script>
<link href="/static/css/main.073c9b0a.css" rel="stylesheet">
</head>
<body><noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
Now, Instead of the URLs starting with /static I want them to add a prefix automatically when build is generated such as /test/static in src as well as href tag. Please help. Thanks in advance.
To configure the react build, do the following:
run: npm run eject or yarn eject
The repository has to be at the latest commit, otherwise the command will not generate the configuration files. The command will generate configuration files for create-react-app.
Once you see that the files are generated, look for the following file:
config/webpack.config.js
With your text editor look for something like static/ you will see that it is the path configured for the static files. You can replace it with a route of your choice.
Warning: A configuration error in this file may cause your project not to compile or the development server not to start.
New to react js and firebase
I have a firebase project, I did the init and deploy, but the index.html was a generic file.
I copied the index.html from the public directory in the build directory (which is the folder specified in hosting firebase.json)
when I start the app the page is empty.

that "root" bit might be the problem.
this is the index.js file
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
serviceWorker.unregister();
when I access the link it's just an empty page
There is a line of <div style={height: 50px}> where height is 50px i want to make it 0 in code but where it is located?

There is a white spacing showing and height was the reason so I want to make it 0. I try to find in different files but i don't know where exactly it is
Any help will be appreciated
Thanks In Advance
I am assuming that you want to find react component responsible for that. You may want to use components tab in developer tools to find out which component is responsible for rendering a particular element. link - https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en With that you can hover on an element and corresponding component gets highlighted.
This looks something like following -
