how to render to a page whenever user click to a dynamic url ReactJS?

Question

what i am trying to solve is, how to render to a specific page whenever user click to dynamic url? for more specific, there is my "product_list" api data. in "product_list" api data there is a key "url", whenever user click on this "url" then user will be redirect to another specific "product_detail" page. how to implement that specific dynamic url page to a specific page? so whenever user will click the url then user will see a specific UI page, not that dynamic url page.

i am probably new to reactjs. i am trying to solve this problem but i have no idea where i am doing thing wrong. it would be great if anybody could help me out what i am trying to solve is. thank you so much in advance.

// product_list api-data -->

[
    {
        "url": "http://localhost:8000/api/p/product01",
        "id": 19,
        "title": "product01",
        "slug": "product01",
        "description": "product01descc",
        "image": "http://localhost:8000/media/google.com/images/tet0.png",
        "price": 1,
        "status": true,
        "created_on": "2020-04-19T03:45:12Z"
    },
    {
        "url": "http://localhost:8000/api/p/product02",
        "id": 20,
        "title": "product02",
        "slug": "product02",
        "description": "product01descc",
        "image": "http://localhost:8000/media/google.com/images/tet0.png",
        "price": 2,
        "status": true,
        "created_on": "2020-04-19T03:45:12Z"
    }
]

product detail api-data of specific product list, for e.g "product-01".

{
    "id": 19,
    "title": "product01",
    "slug": "product01",
    "description": "product01descc",
    "image": "http://localhost:8000/media/google.com/images/tet0.png",
    "price": 1,
    "created_on": "2020-04-19T03:45:12Z",
    "status": true,
    "color": 1,
    "size": 1,
    "product_category": []
}

my efforts to trying to solve this problem.

./src/productList.js

import React, {Component} from "react";
import Contacts from './productListHook.js';


export default class App  extends Component{

    state = {
        contacts: [

        ]
    }

    contactList() {
        fetch('http://localhost:8000/api/p_list')
        .then(res => res.json())
        .then((data) => {
          this.setState({ contacts: data })
        })
        .catch(console.log)
      }

    render(){
    return(

        <Contacts contacts={this.state.contacts} />
    )
 }
}

in this page, whenever i am trying to rendering user, when user click to the "title" as you can see below. but that page rendering user to the api-detail page. obviously that would be cause i did not implement to that api-detail page to a specific page where user will see the UI detail page. how to do implement that in reactjs?

./src/productListHook.js

import React from 'react'

    const Contacts = ({ contacts }) => {
      return (
            {contacts.map((contact) => (
            <img src={contact.image} alt="" class="img-fluid" />
            <h3> <a href={contact.url}>{contact.title}</a> </h3>

            ))}
      )
    };

export default Contacts

Another way to approach this would be to add a <Link /> component in the map function of contacts and pass down the details as props. Also, you have to set up the Router component to render the page. Assuming <App /> as your root component, you have to wrap this component with BrowserRouter inside your index.js file. Here's a working sandbox.

//Contacts.js
import React from "react";
import { Link } from "react-router-dom";

const Contacts = ({ contacts }) => {
  return (
    <div>
      {contacts.map((contact) => (
        <div key={contact.id>>
          <img src={contact.image} alt="" className="img-fluid" />
          <h3>
            {" "}
            <Link
              to={{
                pathname: `/productdetails/${contact.id}`,
                contact: contact,
              }}
            >
              {contact.title}
            </Link>
          </h3>
        </div>
      ))}
    </div>
  );
};

export default Contacts;

//App.js
import React from "react";
import { Route, Switch } from "react-router-dom";
import Home from "./Home";
import ProductDetails from "./ProductDetails";

function App() {
  return (
    <div className="App">
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/productdetails/:slug" component={ProductDetails} />
      </Switch>
    </div>
  );
}

export default App;

The Home component in the App.js would be the App.js in your question.

//ProductDetails.js
import React from "react";
import {  useLocation } from "react-router-dom";

function ProductDetails({ location }) {
  const { contact } = location;
  console.log(contact);
  let queryParams= useLocation();
  console.log(queryParams)
  return (
    <div>
      <h1>Product Details Page</h1>;
    </div>
  );
}

export default ProductDetails;

In the ProductDetails component, you can access queryParams and the props passed down from Contacts component with which you can make additional API requests to render data.

For dynamic URLs, you may not want to go with absolute paths. Consider shifting to query parameters.

Change url to http://localhost:8000/api/p?id=product01. In routing, render ProductDetailContainer for url 'http://localhost:8000/api/p'.

function ProductDetailContainer() {
    const query = new URLSearchParams(useLocation().search); // useLocation in react-router

    return <ProductDetail id={query.get('id')} />;
}

function ProductDetail({id}) {
    return ({id}); // Render details based on the ID fetched.
}

Code above is not tested. Please adapt accordingly :)

Hope it helps.
