React Project working but not displaying some components

i am trying to build a portfolio website using react and i am using react-router-dom for navigation.
everything was working for a while then i made a stupid mistake of keeping the project in onedrive and had some trouble.
link to code: https://github.com/Raghav-rv28/portfolio-website
Live: https://raghav-rv28.github.io/portfolio-website/, this is not really helpful as we cannot see anything but you can see the screenshots below,
when i run the project on my local machine it runs :
as you can see the elements are there but they just don't appear to me for some reason.
Some of the Code:
import React from 'react'
import {Route, Routes} from 'react-router-dom'
import Layout from './Components/Layout'
import Home from './Components/Home'
import About from './Components/About'
import Contact from './Components/Contact'
import Interests from './Components/Interests'
import Projects from './Components/Projects'
import './App.scss';
function App() {
return (
<>
<Routes>
<Route path="/" element = { <Layout />} >
<Route index element={< Home/>} />
<Route path='About' element={< About/>} />
<Route path='Contact' element={< Contact/>} />
<Route path='Interests' element={< Interests/>} />
<Route path='Projects' element={< Projects/>} />
</Route>
</Routes>
</>
);
}
export default App;
Layout.js:
import React from 'react';
import './index.scss';
import SideNavbar from '../SideNavbar/index';
import { Outlet } from 'react-router-dom';
export default function Layout(){
return(
<div className="App">
<SideNavbar />
<div className="page">
<Outlet />
</div>
</div>)
}
index.js :
import React from 'react';
import ReactDOM from 'react-dom';
import {BrowserRouter} from 'react-router-dom'
import './index.css';
import App from './App';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);

You nested your routes for (Home, About, Contact, etc.) inside the "Layout" route. This means that react router will render BOTH "Layout" and whichever component is provided by a matching nested route.
Try restructuring your routes like this:
<>
<Routes>
<Route path="/" element = { <Layout />} />
<Route index element={< Home/>} />
<Route path='About' element={< About/>} />
<Route path='Contact' element={< Contact/>} />
<Route path='Interests' element={< Interests/>} />
<Route path='Projects' element={< Projects/>} />
</Routes>
</>

Turns out my stupid As* forgot to import the animation library i'm using and the opacity for the pages was set to 0.

ReactJS Route function isn't working for me

I started learning ReactJS yesterday using Academind's crash course for beginners on it. There is a part where he teaches about react-router-dom. I tried using it on App.js and index.js as such:
App.js:
import { Route } from "react-router-dom";
import AllMeetupsPage from "./pages/AllMeetups";
import FavouritesPage from "./pages/Favourites";
import NewMeetupsPage from "./pages/NewMeetups";
function App() {
return (
<div>
<Route path='/'>
<AllMeetupsPage />
</Route>
<Route path='/favourites'>
<FavouritesPage />
</Route>
<Route path='/new-meetups'>
<NewMeetupsPage />
</Route>
</div>
);
}
export default App;
index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom'
import './index.css';
import App from './App';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById('root')
);
There shouldn't be any error since I have fixed the syntax and imported the right files given in the video. Yet, in localhost:3000 I get this as the result.
If I just use <AllMeetupsPage /> then it works. If I put it in the route function then it doesn't. How can I fix this?

When you are just using <AllMeetupsPage/> then it's directly rendering that page component in App.js.
It's actually not doing any routing.
To use multiple you also need to wrap it within .
<div>
<Routes>
<Route path="/" element={<AllMeetupsPage />} />
<Route path="/favourites" element={<FavouritesPage />} />
<Route path="/new-meetups" element={<NewMeetupsPage />} />
</Routes>
</div>
You can refer to the following link to get more context of the problem:
[1]: ReactJS: [Home] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

tyr this
import {Routes} from "react-router-dom"
<Routes>
<Route path='/'>
<AllMeetupsPage />
</Route>
<Route path='/favourites'>
<FavouritesPage />
</Route>
<Route path='/new-meetups'>
<NewMeetupsPage />
</Route>
</Routes>

Issues in making Routes in Reactjs

I am making a project and getting some problem in managing routes. My Frontend is divided in two parts. One For the Client side and onother is the admin-panel for handling the Client side. For example if I add some Blog from admin-panel then it shows on Client-side. Admin-Panel is for my team to handle the website. Suppose Users will visit on my website at "www.mywebsite.com' and I want that if I enter "www.mywebsite.com/admin" then Admin-panel and Admin-components should open instead of Nav-Components.
How Do I achieve this conditional routing?
Here is the App.js
import React, { Component, useEffect, useState } from "react";
import { Route, Switch } from "react-router-dom";
import Landing from "./components/Landing";
import Home from "./components/Home";
import About from "./components/About";
import Teams from "./components/Team";
import Events from "./components/Events";
import NotFound from "./components/NotFound";
import Blog from "./components/Blog";
import ContactUs from "./components/Contact";
import ComingSoon from "./components/ComingSoon";
import Navbar from "./components/Navbar";
import EventInfo from "./components/EventInfo";
import AdminNavbar from "./admin-panel/AdmiNavbar";
import Login from "./admin-panel/Login";
import Eventadd from "./admin-panel/Eventadd";
import Blogadd from "./admin-panel/Blogadd";
import Dashboard from "./admin-panel/Dashboard";
const NavComponents = () => {
return (
<>
<Switch>
<Route path="/home" exact component={Home} />
<Route path="/about" exact component={About} />
<Route path="/events" exact component={Events} />
<Route path="/team" exact component={Teams} />
<Route path="/blog" exact component={Blog} />
<Route path="/contact" exact component={ContactUs} />
<Route path="/comingsoon" exact component={ComingSoon} />
<Route path="/eventinfo/:eventName" exact component={EventInfo} />
<Route component={NotFound} />
</Switch>
</>
);
};
const AdminPanel = () =>{
return(
<>
<Switch>
<Route path="/admin/Eventadd" exact component={Eventadd}/>
<Route path="/admin/Blogadd" exact component={Blogadd}/>
<Route path="/admin/DashBoard" exact component={Dashboard}/>
<Route component={NotFound} />
</Switch>
</>
);
};
class App extends Component {
render() {
return (
<>
{window.location.pathname=="/"?"": <Navbar />}
<Switch>
<Route path="/" exact component={Landing} />
<NavComponents />
</Switch>
</>
);
}
}
export default App;

I assume if users enter your website through "www.mywebsite.com/admin" link, you want to re-route them to "/admin/DashBoard" route? The admin dashboard doesn't show because, it only returns the route with EXACT match. It's possible to
A) Add an additional path to handle the routing
<Route path=["/admin/DashBoard", "/admin"] exact component={Dashboard}/>
B) Add a Redirect for admin if you prefer to keep the route as /admin/dashboard
<Redirect exact from="/admin" to={`/admin/dashboard`} />
Edit: (Most importantly)
Also, noticed that you did not include the admin into the main router. You don't need to separate the admin from nav. Suggest to read on the document
https://reactrouter.com/web/api/Switch
Switch renders the first child <Route> or <Redirect> that matches the location.
Overall, it should be combined like this
<Switch>
...user paths
...admin paths
</Switch>

React Router v5 nested routes not found

I'm having problems trying to make a simple setup to run. I have used "react-router-dom" because it claims to be the most documented router around.
Unfortunately, the documentation samples are using functions instead of classes and I think a running sample will not explain how routes have changed from previous versions... you need a good sight!. Btw, there are a lot of breaking changes between versions.
I want the following component structure:
Home
Login
Register
Recipes
Ingredients
Have the following components:
index.js (works fine)
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route } from 'react-router-dom';
import App from './App';
ReactDOM.render((
<BrowserRouter>
<Route component={App}/>
</BrowserRouter>
), document.getElementById('root'));
App.js (fine)
import React from 'react';
import { Route, Switch } from 'react-router-dom';
import Home from './Home'
import Recipes from './recipes/Recipes'
import Ingredients from './ingredients/Ingredients'
class App extends React.Component {
render() {
return (
<div id="App">
<Switch>
<Route exact path='/home' component={Home} />
<Route path='/recipes' component={Recipes} />
<Route path='/ingredients' component={Ingredients} />
<Route render={() => <h1>Not found!</h1>} />
</Switch>
</div>
);
}
}
export default YanuqApp;
Ingredients and Recipes components working fine, so I'll skip from here
Home.js - The problem starts here. Home itself loads correctly, but once Login or Register links are clicked, it shows "Not found!" (fallback route in App.js)
import React from 'react';
import { Switch, Route, Link } from 'react-router-dom';
import Register from './account/register'
import Login from './account/login'
class Home extends React.Component {
render() {
return (
<div>
<div>
This is the home page...<br/>
<Link to='/home/login'>Login</Link><br />
<Link to='/home/register'>Register</Link><br />
</div>
<Switch>
<Route path='/home/login' component={Login} />
<Route path='/home/register' component={Register} />
</Switch>
</div>
);
}
}
export default Home;
Login and register are very similar:
import React from 'react';
class Login extends React.Component {
render() {
alert("login");
return (
<div>Login goes here...</div>
);
}
}
export default Login;
And cannot figure why Login and Register are not found. I have tried also defining routes as:
<Link to={`${match.path}/register`}>Register</Link>
...
<Route path={`${match.path}/register`} component={Register} />
(don't see the gain on using match, as it renders as the expected "/home/register"), but the problem persists in identical way

I think it's because of the exact flag on the Route for home. It does not match the /home exact so it goes to the default not found page.

try to add this in App.js
<Switch>
<Route exact path='/' component={Home} />
<Route path='/recipes' component={Recipes} />
<Route path='/ingredients' component={Ingredients} />
<Route path='/login' component={Login} />
<Route path='/register' component={Register} />
<Route render={() => <h1>Not found!</h1>} />
</Switch>
to this is work
<Link to={`${match.path}/register`}>Register</Link>
...
<Route path={`${match.path}/register`} component={Register} />
you should provide match as the props because cont access directly to the match to used it you should provide a match as this following
const namepage=({match})=>{
<Link to={`${match.path}/register`}>Register</Link>
...
<Route path={`${match.path}/register`} component={Register} />
})

React Router Switch not rendering specific component

I have a React app that is currently using react-router#4.2.0 and I'm struggling with rendering a specific component when the URL changes.
When I try to visit /locations/new it returns with a PropTypes error from the CityList component. I have tried adding in exact to the Route component within LocationsWrapper and then Main config too, however, this then influences other routes - such as /locations to become null.
// BrowserRouter
import React from "react";
import { render } from "react-dom";
import { BrowserRouter } from "react-router-dom";
import { Provider } from "react-redux";
import store from "./store";
import Navbar from "./components/Core/Navbar";
import Routes from "./config/routes";
render(
<Provider store={store}>
<BrowserRouter>
<div style={{ backgroundColor: "#FCFCFC" }}>
<Navbar />
<Routes />
</div>
</BrowserRouter>
</Provider>,
document.getElementById("root")
);
// Router config - ( Routes )
import React from "react";
import { Route, Switch } from "react-router-dom";
import Home from "../components/Home";
import Locations from "../components/Locations";
import CityList from "../components/CityList";
import CreateLocation from "../components/CreateLocation";
import Locale from "../components/Locale/index";
import Profile from "../components/Profile";
import NoMatch from "../components/Core/NoMatch";
import requireAuth from "../components/Core/HOC/Auth";
const LocationsWrapper = () => (
<div>
<Route exact path="/locations" component={Locations} />
<Route path="/locations/new" component={CreateLocation} />
<Route path="/locations/:id" component={CityList} />
</div>
);
const Main = () => (
<main>
<Switch>
<Route exact path="/" component={requireAuth(Home)} />
<Route path="/locations" component={LocationsWrapper} />
<Route path="/locale/:id" component={Locale} />
<Route path="/profile" component={requireAuth(Profile, true)} />
<Route component={NoMatch} />
</Switch>
</main>
);
export default Main;
Am I best avoiding <Switch> entirely and implementing a new method for routes that are undefined - such as 404s?

Yes, this will definitely return first
<Route path="/locations/:id" component={CityList} />
In react-router 4 there is no concept of index route, it will check each and every routes so in your defining routes are same
<Route path="/locations/new" component={CreateLocation} />
<Route path="/locations/:id" component={CityList} />
both path are same '/location/new' and '/location/:id' so /new and /:id are same params.
so at last 'CityList' will return
You can define like this
<Route path="/locations/create/new" component={CreateLocation} />
<Route path="/locations/list/:id" component={CityList} />

Pretty sure your route is not working cause you are also matching params with /locations/new with /locations/:id so then 'new' becomes Id param.
Try changing this
<Route path="/locations/new" component={CreateLocation} />
To something like this
<Route path="/locs/new" component={CreateLocation} />
Just a suggestion hope this may help
