React Routing for Beginners

Routing helps you to navigate one page to another page . But Before React we had to use the “href” attribute to navigate. In that case we had to load that other page from the server which was time consuming, but with React Router that is so easy and faster because we don’t have to load that page from the server. We just render a page(component) depending on that route path. Don’t worry we will explain this(route) later . In this tutorial we will learn how to use Router in React Web App. If you do not know about React, then see this first

If you want to get started with React Routing you need a React Web App. Let’s start have a React App using yarn or npm command like this

To work with react router in web app you need to install react-router-dom module using npm or yarn command

Let’s create some demo components under “src/components” folder like this

Let’s now make route for those components in “App.js” and import some properties from “react-router-dom”

Where Router is defined for all the Route we need and Route is needed for all pages(components) we need to render . It will be clear if you see full App.js

Route has path property which determines the where we want to go if this Route is hit and component determines which page(component) will be shown if we hit that Route.

And switch renders the first path match it finds.

But there is a problem if we hit “localhost/about”

It will be like this

It should be About only for that we have to use a keyword “exact” like this

Before use of exact to React “/” and “/about” was same cause both have “/” in path string

Now “/” means to React is only and only “/”

Now hitt “/About” and it will show like this

What we expected before. It is all about basic Routing in React .In future tutorials we will discuss how we handle dynamic route and access parameters from route path.

So that’s it . Happy Coding…….
