A 404 page is what a user sees when they try to reach a non-existent page on your site (because they’ve clicked on a broken link, the page has been deleted, or they’ve mistyped a URL).

I am assuming you are using React Router. You have two options to show page not found component

  1. Redirect to yoursite.com/404
  2. Show Page not found content with requested URL.

In Order to redirect you need to import Redirect from “react-router-dom”. Place the redirect code at the very last path of your routes.

Introduction

Unlike Angular, React doesn’t come with its own fetching library. So the developer came with their own implementation to fetch the data from the server. But the problem is, it is very hard to code the caching based fetching system to effectively avoid network call duplication.

So they are choosing a very simple library to fetch the data like fetch, Axios, etc.

React Query

It comes with its own Developer tool called ReactQueryDevtools
