Hey. When I try to click article names, it redirects to the /objects and others rather than /articles/object. Here is my app.js code

import React from "react";
import About from "../components/About";
import SignUp from "../components/SignUp";
import Articles from "../components/Articles";
import Article from "../components/Article";
import Categories from "../components/Categories";
import Category from "../components/Category";
import Author from "../components/Author";
import Profile from "../components/Profile";
import EditProfileForm from "../components/EditProfileForm";
import Root from "../components/Root";

import { Route, RouterProvider, createBrowserRouter, createRoutesFromElements } from 'react-router-dom';

import "./App.css";

const router = createBrowserRouter(createRoutesFromElements(
  /* Wrap this Root Route to create Router here */
  <Route path="/" element={<Root />}>
    <Route path="about" element={<About />} />
    <Route path="sign-up" element={<SignUp />} />
    <Route exact path="articles" element={<Articles />} />
    <Route path="articles/:title" element={<Article />} />
    <Route path="categories" element={<Categories />} />
    <Route path="profile" element={<Profile />} />
  </Route>
))


function App() {
  return (
    <>
      <RouterProvider router={router} />
    </>
  );
}

export default App;

I have tried adding “exact” word as suggested in this post but didn’t work.

I have the exact same issue. Please Help!!!

Are there any updates to this?

I recently started coding, so sorry if my response is a bit late, you don’t need the “exact” keyword for the path. I just found out that for the previous step when you import the {Link} from react-router-dom" you need to make you compile (Crtl + S) the “Article.js” component. That fixed it for me anyway :slight_smile:

Issue: React Router Not Rerouting Properly to Dynamic Article Pages

Problem

In a React application, clicking on links within Articles.js was not routing to the dynamic Article.js component properly. The links were created using <a> tags, which caused a full page reload instead of using React Router’s dynamic routing.

Solution

To enable React Router to handle the routing without reloading the page:

  1. Replace <a> Tags with React Router’s <Link> Component:

    • Import Link from react-router-dom in Articles.js.
    • Replace <a> tags with <Link to={...}> to leverage React Router’s routing capabilities.

  2. Update Articles.js Component:

    • Use <Link> to dynamically construct the route based on each article’s unique slug or identifier:
      import { Link } from "react-router-dom";
// ...
<Link to={`/articles/${article.slug}`}>
  {article.title}
</Link>

  3. Ensure Dynamic Route is Set Up in App.js:

    • Confirm the route for articles/:title is defined in your main router configuration:
      <Route path="articles/:title" element={<Article />} />

  4. Confirm Article.js Uses useParams() to Retrieve Dynamic Data:

    • In Article.js, retrieve the title parameter from the URL using useParams() to display the appropriate article content.

Result

With these changes, clicking on an article link in Articles.js will correctly route to Article.js using the articles/:title route, allowing React Router to render the content dynamically without reloading the page.
