Why my components don't display on my React page? - javascript

So I'm learning React and building an app with multiple pages, I made a Routes file which looks like this:
import 'swiper/swiper.min.css';
import React from "react";
import { Route, Routes } from "react-router-dom";
import Home from "../pages/Home";
import Catalog from "../pages/Catalog";
import Detail from "../pages/Detail";
const Router = () => {
return (
<Routes>
<Route
path='/:category/search/:keyword'
component={Catalog}
/>
<Route
path='/:category/:id'
component={Detail}
/>
<Route
path='/:category'
component={Catalog}
/>
<Route
path='/'
exact
component={Home}
/>
</Routes>
);
}
And App.js looks like this:
import { BrowserRouter, Route, Routes } from 'react-router-dom';
import Header from './components/header/Header';
import Footer from './components/footer/Footer';
import Router from './config/Router';
function App() {
return (
<BrowserRouter>
<Routes>
<Route render={props =>{
<>
<Header {...props}/>
<Router/>
<Footer/>
</>
}}/>
</Routes>
</BrowserRouter>
);
}
export default App;
As you see, I have a browser router and Route which passes props to a component(as I understood) but for some reason the components don't display on the page(original components just have with their name inside of them, but they don't display in App.js).
And my console also says:
No routes matched location "/"
In routes.jsx file. I'm guessing it should lead to main page, but for some reason the route doesn't match and components in App.js don't display.

In Version 6.0.0 there is not any component prop in Route. It has been changed to element. So you need to change your Router to :
const Router = () => {
return (
<Routes>
<Route
path='/:category/search/:keyword'
element={Catalog}
/>
<Route
path='/:category/:id'
element={Detail}
/>
<Route
path='/:category'
element={Catalog}
/>
<Route
path='/'
exact
element={Home}
/>
</Routes>
);
}

As you've said you're using react-router-dom 6.0.2, and it seems that the tutorial you are following is for the older version (5?). There were some breaking changes in version 6.
You need to change your Router component to use element instead of component:
const Router = () => {
return (
<Routes>
<Route path="/:category/search/:keyword" element={<Catalog />} />
<Route path="/:category/:id" element={<Detail />} />
<Route path="/:category" element={<Catalog />} />
<Route path="/" exact element={<Home />} />
</Routes>
);
};
and also your App component seems to be getting in the way with the nested route.
I think it can be simplified to:
function App() {
return (
<BrowserRouter>
<>
<Header />
<Router />
<Footer />
</>
</BrowserRouter>
);
}
You can see a working demo on stackblitz

Why unable to use protectRoute inside Router in react?

I have a react application in which users can access the homepage only after login/signup.
I have used protectRoutes to implement this , however I m getting the following error inside Router component:
A <Route> is only ever to be used as the child of <Routes> element, never rendered directly. Please wrap your <Route> in a <Routes>.
The code for app.js file:
import {useState} from 'react'
import './App.css';
import {Routes,Route,Link} from 'react-router-dom'
import SignupPage from './Pages/SignupPage';
import LoginPage from './Pages/LoginPage';
import Homepage from './Pages/Homepage';
import PrivateRoute from "./Pages/PrivateRoute";
import {HashRouter as Router} from 'react-router-dom'
function App() {
const [username,setUsername]=useState("");
const [currentUser,setCurrentUser]=useState({});
return (
<Router>
<div className="App">
<Route path="/" exact element={<SignupPage></SignupPage>}/>
<Route path="/signup" exact element={<SignupPage currentuser={currentUser} setcurrentuser={setCurrentUser} setusername={setUsername}></SignupPage>}/>
<Route path="/login" exact element={<LoginPage></LoginPage>}/>
<PrivateRoute path="/homepage" exact currentuser={currentUser} element={<Homepage user={currentUser} username={username} setusername={setUsername}></Homepage>}/>
</div>
</Router>
);
}
export default App;
Whats the error here and how do I fix it?
Issue
You are rendering Route components directly and are not wrapping them in a Routes component.
Solution
Refactor the PrivateRoute component to render an Outlet component instead of a Route and wrap the routes you want to protect.
Example:
import { Navigate, Outlet } from 'react-router-dom';
const PrivateRoute = ({ currentuser }) => {
// auth business logic
return isAuthenticated
? <Outlet />
: <Navigate to="/login" replace />;
};
...
import { HashRouter as Router, Routes, Route, Link} from 'react-router-dom'
function App() {
const [username,setUsername]=useState("");
const [currentUser,setCurrentUser]=useState({});
return (
<Router>
<div className="App">
<Routes>
... unprotected routes ...
<Route path="/" element={<SignupPage />} />
<Route
path="/signup"
element={(
<SignupPage
currentuser={currentUser}
setcurrentuser={setCurrentUser}
setusername={setUsername}
/>
)}
/>
<Route path="/login" element={<LoginPage />} />
...
<Route element={<PrivateRoute currentuser={currentUser} />}>
... protected routes ...
<Route
path="/homepage"
element={(
<Homepage
user={currentUser}
username={username}
setusername={setUsername}
/>
)}
/>
...
</Route>
</Routes>
</div>
</Router>
);
}

why Passing Props in Private Route in ReactJs not working properly

Here is mycode of the file PrivateRoute.js
import React from "react";
import {Route,Redirect} from "react-router-dom"
import {isAuthenticated} from "./index"
const PrivateRoutes = (props)=>{
return(
isAuthenticated()?(<Route
render={ (props) =>
<component {...props}/>} />):
(<Redirect to={{ pathname:"/signin"}}/>)
// <h1>hey there</h1>
)
}
export default PrivateRoutes;
In this code it is saying that value of props is read but never used but iam using it in render function,destructuring is also not working here.
Here isAuthenticated() is my boolean function . If it evaluates to true i want to get on more route to user dashboard.
This is how my routes.js file looks like
import React from 'react'
import {BrowserRouter,Route,Switch} from "react-router-dom";
import AdminRoutes from './auth/helper/AdminRoutes';
import PrivateRoutes from './auth/helper/PrivateRoutes';
import Home from './core/Home';
import AdminDashboard from './user/AdminDashBoard';
import Signin from './user/Signin';
import Signup from './user/Signup';
import UserDashboard from './user/UserDashBoard';
function Routes() {
return (
<BrowserRouter>
<Switch>
<Route exact path='/' component={Home} />
<Route exact path="/signup" component={Signup} />
<Route exact path="/signin" component={Signin} />
<PrivateRoutes component="UserDashboard" exact path="/user/dashboard"/>
<AdminRoutes exact path="/admin/dashboard" component={AdminDashboard}/>
</Switch>
</BrowserRouter>
)
}
export default Routes
Help me to solve this problem.
This is because you have declared *two functions, each taking a props object argument, but only the inner/nested function's props is referenced.
Rename the nested props to something else like routeProps and spread both to the rendered component. Remember also that valid React component names are PascalCased.
Example:
const PrivateRoutes = ({ component: Component, ...props }) => {
return isAuthenticated()
? (
<Route
render={(routeProps) => (
<Component {...props} {...routeProps} />
)}
/>
) : <Redirect to={{ pathname:"/signin"}}/>;
}
Then also fix the PrivateRoutes component use to pass a value React component reference instead of a string.
<Switch>
<Route path="/signup" component={Signup} />
<Route path="/signin" component={Signin} />
<PrivateRoutes component={UserDashboard} path="/user/dashboard" />
<AdminRoutes path="/admin/dashboard" component={AdminDashboard} />
<Route path='/' component={Home} />
</Switch>

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>

Why is my React Router selecting two Routes in a nested Switch?

My App.js is as such:
const App = () => {
return (
<div className="App">
<Router>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/studio">
<Studio />
</Route>
<Route path="*" component={NotFound} />
</Switch>
</Router>
</div>
)
}
& my Studio.js is as follows:
const Studio = () => {
let { path } = useRouteMatch()
return (
<>
<Switch>
<Route exact path={path}>
<Editor />
</Route>
<Route path={`${path}/categories`}>Studio/Categories</Route>
<Route component={NotFound} />
{/* <Route exact path={`${path}/*`} component={NotFound} /> */}
</Switch>
</>
)
}
It seems routing is working perfectly fine for App.js but for Studio.js, the Switch doesn't stop at the first match and is rendering <NotFound/> when visiting /studio as well as /studio/categories.
What can I do to make it work such that only one Route is rendered within the Switch which is the default behaviour as per the docs if I'm not wrong?
Reproducible SandBox: https://codesandbox.io/s/react-router-nested-glled
You have import typo BrowserRouter as Switch, you just need to import regular Switch in Nested component
import {
BrowserRouter as Switch, // remove `BrowserRouter as` thing
Route,
useRouteMatch
} from "react-router-dom";

Programmatically navigate while using HashRouter

I'm using HashRouter for my routes in a react.js app. I then have a function which does the following:
this.props.history.push('/somePath');
The problem is, ever since I started using HashRouter, the page doesn't push to that path when that function gets called.
I logged this.props.history, and push was there.
How can I programmatically navigate while using HashRouter?
Note: I used withRouter
Here's the code:
import React, { Component } from 'react';
import { HashRouter, Route, Switch, Redirect, withRouter } from 'react-router-dom';
// Other imports
class App extends Component {
navigate = () => {
this.props.history.push('/route1');
console.log(this.props.history);
};
render() {
return (
<div className="App">
<Header />
<HashRouter>
<Switch>
<Route
path="/route1"
exact
render={() => (
<FirstRoute someSetting='setting1'/>
)}
/>
<Route
path="/route2"
exact
render={() => (
<SecondRoute anotherSetting='Really Cool'/>
)}
/>
<Route path="/404" component={NotFound} />
<Route exact path="/" render={() => <HomePage someSettings='Home Page' />} />
<Redirect to="/404" />
</Switch>
</HashRouter>
<BottomBar />
</div>
);
}
}
export default withRouter(App);
