adding a router with tailwind and react 6

Question

React 6 has done away with switch but I am not sure how to implement a router with tailwind or html tags. Currently I am getting an error that reads.

router.ts:5 Uncaught Error: useHref() may be used only in the context of a <Router> component.

but this is confusing and not very descriptive.

import React, {Component, Fragment} from 'react';
import {BrowserRouter, Routes, Route, Link} from "react-router-dom";
import About from "../about/about";
import Home from "../home/home";
import Blog from "../blog/blog";
import Contact from "../contact/contact";
import Tutorials from "../tutorials/tutorials";

export default class Header extends Component {

  render() {
      return (
              <nav className="flex items-center justify-between flex-wrap bg-blue-500 p-6">

Answer 1

The error is telling you exactly what the issue is. You are using something that needs to be within your <Router/>

I am assuming the issue is coming from the the <Header/> which right now doesn't look like it is being mounted within the router. Since you are using the Link component in your <Header/> then it needs to be within the <BrowserRouter> so it knows where to navigate to.

function r() {
    return(
        <BrowserRouter>
           
            <Header/>

            <Routes>
                <Route path="/" element={<Home/>}/>
                <Route path="/tutorials" element={<Tutorials/>}/>
                <Route path="/about" element={<About/>}/>
                <Route path="/blog" element={<Blog/>}/>
                <Route path="/contact" element={<Contact/>}/>
            </Routes>
        </BrowserRouter>
    )
}
