I'm using #tanstack/react-location in React Typescript project + 'react-redux'.
When I change redux auth state (login, logout) I also make my MainNavigation changing. Some Links are added or removed. And when it happens the router stops working.
Updated Links are working, url is changing, but Router isn't responding.
After refresh Router works again.
App.tsx
...
<Router
location={reactLocation}
routes={appRoutes}
defaultPendingElement={<Spinner />}
defaultPendingMs={10}
>
<MainNavigation />
<Outlet />
</Router>
MainNavigation.tsx
<header className="header">
<Link to="/" getActiveProps={getActiveProps}>
<div className="logo">RS Lang</div>
</Link>
<nav>
<ul>
<li>
<Link to="/" getActiveProps={getActiveProps}>
Home
</Link>
</li>
<li>
<Link to="/team" getActiveProps={getActiveProps}>
Team{' '}
</Link>
</li>
<li>
<Link to="/textbook" getActiveProps={getActiveProps}>
Textbook
</Link>
</li>
{isLoggedIn && (
<li>
<Link to="/dictionary" getActiveProps={getActiveProps}>
Dictionary
</Link>
</li>
)}
<li>
<Link to="/games" getActiveProps={getActiveProps}>
Games
</Link>
</li>
{!isLoggedIn && (
<li>
<Link to="/auth" getActiveProps={getActiveProps}>
Login|SignUp
</Link>
</li>
)}
{isLoggedIn && (
<li>
<Link to="/profile" getActiveProps={getActiveProps}>
Profile {authState.user.name}
</Link>
</li>
)}
{isLoggedIn && (
<li>
<button type="button" onClick={logoutHandler}>
Logout
</button>
</li>
)}
</ul>
</nav>
</header>
for me the issue was that the definition of the ReactLocation was not in the main.tsx. So I fixed it like so:
main.tsx
export const reactLocation = new ReactLocation();
ReactDOM.createRoot(document.getElementById('root')!).render(<App />);
App.tsx
import { reactLocation} from './main.tsx';
export const App = () => {
return <Router
location={reactLocation}
routes={appRoutes}
defaultPendingElement={<Spinner />}
defaultPendingMs={10}
>
<MainNavigation />
<Outlet />
</Router>
}
Hope that helps :)

I would like all the elements nested inside of the first Nav tag to be on the left side of the NavBar, and all in the second Nav tag to float right. How can I achieve this using react Bootstrap?
I tried doing Nav className="float-right" on the second Nav tag but it didn't work. I also tried className="ml-auto".
<Nav>
<Nav.Link>
{" "}
<Link
to="/booklets"
className="nav-link"
onClick={() => setExpanded(false)}
>
Booklets
</Link>
</Nav.Link>
<Nav.Link>
{" "}
<Link
to="/form"
className="nav-link"
onClick={() => setExpanded(false)}
>
Upload New Booklet
</Link>
</Nav.Link>
<Nav.Link>
{" "}
<Link
to="/about"
className="nav-link"
onClick={() => setExpanded(false)}
>
About
</Link>
</Nav.Link>
</Nav>
<Nav>
<Nav.Link>
{" "}
<Link
to="/login"
className="nav-link"
onClick={() => {
setExpanded(false);
currentUser && logout();
}}
>
{currentUser ? "Logout" : "Login"}
</Link>
</Nav.Link>
<Nav.Link>
{" "}
<Link
to="/register"
className="nav-link"
onClick={() => setExpanded(false)}
>
{!currentUser ? "Register" : ""}
</Link>
</Nav.Link>
</Nav>
</Navbar.Collapse>
</Navbar>
Assuming that the direct parent of the two <Nav> is <Navbar.Collapse>, perhaps try style the parent to have it place the items each on one side, with flex display.
Example with Bootstrap classes:
<Navbar.Collapse className="d-flex justify-content-between">
Example with inline styles:
<Navbar.Collapse style={{ display: 'flex', justifyContent: 'space-between' }}>
I am starting to use React/Next.js and I have got the error:
TypeError: Cannot read properties of undefined (reading 'Item')
When trying to execute the following code in a Next.js application.
The error is due to the header code that is in components->Menu.js file.
I added the menu code after creating the application with npx create-next-app and installing reactstrap
import MyApp from 'next';
import { Nav, Navbar, NavDropdown } from 'reactstrap'
const Menu = () => {
return (
<div>
<Navbar bg="" expand="lg">
<Navbar.Brand href="/">
<h1>Logo</h1>
</Navbar.Brand>
<Navbar.Toggle aria-controls="basic-navbar-nav" />
<Navbar.Collapse id="basic-navbar-nav">
<Nav className="mr-auto">
<Nav.Link title="Página Inicial" href="/">Home</Nav.Link>
<Nav.Link title="Quem Somos" href="/about">About Us</Nav.Link>
<Nav.Link title="Fale conosco" href="/contact">Contact</Nav.Link>
<NavDropdown title="Social" id="basic-nav-dropdown">
<NavDropdown.Item href="https://protonmail.com/" title="Proton" target="_blank">Proton</NavDropdown.Item>
<NavDropdown.Item href="https://www.deepl.com/translator" title="Deepl" target="_blank">Deepl</NavDropdown.Item>
<NavDropdown.Item href="http://duckduckgo.com/" title="DuckDuckGo" target="_blank">DuckDuckGo</NavDropdown.Item>
</NavDropdown>
</Nav>
</Navbar.Collapse>
</Navbar>
</div>
)
}
export default Menu
If I take the NavDropdown out, I get the following error:
Error: Element type is invalid: expected a string (for built-in
components) or a class/function (for composite components) but got:
undefined. You likely forgot to export your component from the file
it's defined in, or you might have mixed up default and named imports.
(The code without NavDropdown is bellow)
<Navbar bg="" expand="lg">
<Navbar.Brand href="/">
<h1>Logo</h1>
</Navbar.Brand>
<Navbar.Toggle aria-controls="basic-navbar-nav" />
<Navbar.Collapse id="basic-navbar-nav">
<Nav className="mr-auto">
<Nav.Link title="Página Inicial" href="/">Home</Nav.Link>
<Nav.Link title="Quem Somos" href="/about">About Us</Nav.Link>
<Nav.Link title="Fale conosco" href="/contact">Contact</Nav.Link>
</Nav>
</Navbar.Collapse>
</Navbar>
I am calling the Menu component in the code bellow:
import Head from 'next/head'
import Image from 'next/image'
import styles from '../styles/Home.module.css'
import 'bootstrap/dist/css/bootstrap.min.css';
import { Button } from 'reactstrap';
import { Nav, Navbar, NavDropdown } from 'reactstrap'
import Menu from '../components/Menu'
export default function Home() {
return (
<div className={styles.container}>
<Head>
<title>Create Next App</title>

<link rel="icon" href="/favicon.ico" />

I got the Menu code from this code: https://github.com/webdeveloperbrasil/next-aula-002
**If I remove the Menu from the code, it works fine.
Im building a react app and I want every route to have a different background color.
But the only way to change the background color of the whole page is by using the * {} tag. Is there some kind of theme library or anything I can do to pass a variable from my routes to the * {} tag to change its background color?
Other solutions would include putting a min-height on my root component but that just feels wrong and I will not do it.
I think you can use this as well
function App() {
const [color, changeColor] = useState("#282c34");
document.body.style.backgroundColor = color;
return (
<div>
<Router>
<div>
<nav>
<ul>
<li>
<Link to="/" onClick={() => changeColor("#282c34")}>
Home
</Link>
</li>
<li>
<Link to="/about/" onClick={() => changeColor("#9c27b0")}>
About
</Link>
</li>
<li>
<Link to="/users/" onClick={() => changeColor("#007bff")}>
Users
</Link>
</li>
</ul>
</nav>
<Route path="/" exact component={Index} />
<Route path="/about/" component={About} />
<Route path="/users/" component={Users} />
</div>
</Router>
</div>
);
}
You can use a state color and pass it to each Route.
This is an exemple to illustrate what i ve told you :
function App() {
const [color, changeColor] = useState("#282c34");
return (
<div style={{ background: color }} id="main">
<Router>
<div>
<nav>
<ul>
<li>
<Link to="/" onClick={() => changeColor("#282c34")}>
Home
</Link>
</li>
<li>
<Link to="/about/" onClick={() => changeColor("#9c27b0")}>
About
</Link>
</li>
<li>
<Link to="/users/" onClick={() => changeColor("#007bff")}>
Users
</Link>
</li>
</ul>
</nav>
<Route path="/" exact component={Index} />
<Route path="/about/" component={About} />
<Route path="/users/" component={Users} />
</div>
</Router>
</div>
);
}
When I import Bootstrap CSS it adds extra CSS to the navbar. As it is shown in the image below. I am using bootstrap cards in this code but not for Navbar. When I remove the Bootstrap CSS It works fine.
You can check the code here
Please help me resolve this.
if your problem is the under line you can omit that using
style={{ textDecoration: 'none' }}
here is your modified navbar.jsx file
// eslint-disable-next-line
import React from 'react';
import { NavLink } from 'react-router-dom';
function Navbar(){
return(
<>
<header className="l-header">
<div className="navi bd-grid">
<div>
<NavLink to="#" className="navi__logo">Portfolio</NavLink>
</div>
<div className="navi__menu" id="navi-menu">
<ul className="navi__list">
<li className="navi__item">
<NavLink to="#home" className="navi__link menu" style={{ textDecoration: 'none' }}>Home</NavLink>
</li>
<li className="navi__item">
<NavLink to="#about" className="navi__link" style={{ textDecoration: 'none' }}>About</NavLink>
</li>
<li className="navi__item">
<NavLink to="#skills" className="navi__link" style={{ textDecoration: 'none' }}>Skills</NavLink>
</li>
<li className="navi__item">
<NavLink to="#work" className="navi__link" style={{ textDecoration: 'none' }}>Work</NavLink>
</li>
<li className="navi__item">
<NavLink to="#contact" className="navi__link" style={{ textDecoration: 'none' }}>Contact</NavLink>
</li>
</ul>
</div>
<div className="navi__toggle" id="navi-toggle">
<i className='bx bx-menu'></i>
</div>
</div>
</header>
</>
);
};
export default Navbar;
output will be something like this
Try to import the bootstrap on your index.js file and it should solve the problem.
I have this following component -
import React from 'react';
import {Route, Link} from 'react-router-dom'
import Error from './Error'
class NavigationBar extends React.Component {
render() {
return (
<div className="nav">
<nav className="navbar navbar-inverse bg-inverse">
<ul className="nav navbar-nav">
<li className="nav-item">
<Link to={"/data"} className="nav-link"> Data </Link>
</li>
<li className="nav-item">
<Link to={"/analysis"} className="nav-link"> Analysis </Link>
</li>
<li className="nav-item">
<Link to={"/Monitor"} className="nav-link"> Monitor </Link>
</li>
</ul>
</nav>
<Route path={"/webiks/:user"} component={Error}/>
</div>
);
}
}
export default NavigationBar;
In addition i added a nav.css file to index.html in order to make some changes to the boostrap styling.
The problem is that when entering the "webkis/:user" url the style only boostrap styling without the changes of the nav.css file.
If one can explaing the reason , and also to mention some of the common methods
for styling components (which is NOT an inline styling).
Thanks.
Place nav.css in the same folder as NavigationBar.js, then add this line on your import list: import './nav.css'
