Getting started with React Router

Introduction

One of the simple definition of routing is navigation between pages. Routing is provided by many JavaScript frameworks especially React. React is a JavaScript library for building user interfaces.

Introducing Routing in React

React provides several libraries for routing. React community provides several routing solutions available here. Let’s take a look at the React routing libraries download statistics over time:

React Router is the popular routing library for React.

Introducing React Router

Built and maintained by React Training team, React Router is a powerful routing library. React Router 4 is the latest version and was divided into four packages:

  • react-router: the core of React Router;
  • react-router-dom: the dom version designed for browsers or web apps;
  • react-router-native: the native version designed for react-native mobile apps;
  • react-router-config: all static route configuration helpers.

What you’ll learn

You’re here to learn about routing in <a href="https://www.dunebook.com/react-examples-best-websites-built-using-react/" target="_blank">React</a> applications, and, in this post, we are going to cover the basics of Routing in React applications. The methods of routing we will explore are:

  • Basic Routing
  • Nested Routes
  • URL Parameters
  • 404 Pages
  • Redirects (Authentication)

Let’s create a simple app to illustrate React Router basics.

We will be using a lot of components which is part of a sample application to explain routing. Take a look at this app:

Where does that come from? 😄

npx create-react-app remote-tools-app
cd remote-tools-app
npm install --save bootstrap
npm install react-router-dom

We installed bootstrap package to make the app look pretty and react-router-dom package. I do not display the complete source code of the files but only the important parts for the understanding of this article. You can access the source code at the end of this article.

The first thing to do is to import BrowserRouter for browser-based projects. Just surround your app with that component. So your app is ready to use React Router.

import { BrowserRouter } from 'react-router-dom';

ReactDOM.render(
    <BrowserRouter>
        <App />
    <BrowserRouter>,
    document.getElementById('root'));

One of the elements that allow us to navigate between pages remains the links. React Router allows you to create components to navigate between pages. For example,

<Link to="/"> Remote tools </Link>

The <Link> component has an attribute called to which is similar to the href attribute.

Once a link is created in your application, it is important to match a link with a React component. Say hello to <Route> component:

<Header />
  <Switch>
    <Route exact path="/" component={Home} />
  <Switch/>
<Footer />

You can simply read the code above like this: switch the <Home> component between Header and Footer components when the path is /. What would become something like below:

<Header /> 
  <Home></Home>
<Footer />

Otherwise, we would have:

<Header /> 
<Footer />

Do you know when we have the case above? When a path does not exist for example (remember page not found errors).

You can handle those cases with React Router too.

<Header /> 
  <Switch> 
    <Route exact path="/" component={Home} /> 
    <Route component={NotFound} /> </Switch>
<Footer />

If the path “/” match display Home component. If not, display <NotFound> component.

When creating applications, you often need to add restrictions: authorization, authentication, etc. For example, you want to prevent <Collection> component from being displayed only for logged users. React Router allows you to create a <PrivateRoute> component:

<Header /> 
  <Switch> 
    <Route exact path="/" component={Home} /> 
    <Route path="/login" component={Login} />
    <PrivateRoute authed={false} path="/collections" component={Collection} /> </Switch>
    <Route component={NotFound} /> 
  </Switch>
<Footer />

React Router lets you create a <PrivateRoute> component. Let’s look at this below:

import React from 'react'
import {
  Route,
  Redirect
} from 'react-router-dom'
 
function PrivateRoute({component: Component, authed, ...rest}) {
  return (
    <Route
      {...rest}
      render={(props) => authed === true
        ? <Component {...props} />
        : <Redirect to="/login" />
      }
  )
}
export default PrivateRoute 

Simple. It is a component that returns a <Route> component based on parameters, including the authed attribute. We use <Redirect> component which allows a redirection if the condition is not fulfilled.

If you want to see if the route is protected, change the authed parameter from false to true and see the result.

At this point, our app is about almost done. We still need to add nested routes.

<Header /> 
  <Switch> 
    <Route exact path="/" component={Home} />
    <Route path="/login" component={Login} />
    <Route path="/products/:product" component={Product} />
    <PrivateRoute authed={false} path="/collections" component={Collection} /> </Switch>
    <Route component={NotFound} /> 
  </Switch>
<Footer />

It’s a <Route> component again with a path (/products/:product) and a component (Product). And you can access this parameter like below:

const Product = ({ match }) => {
  console.log(match.params.product) 
} 

Congrats! You can now play with routing in React apps. The full codebase is on Github.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How React Hooks can replace React Router

Looking to learn more about hookrouter and how it works? Follow along with this tutorial to learn more.

How to Get Started With React Router, In-Depth Explanation With Project

What will you consider most important for any application? don’t get intrigued okay. Just take a minute to think what’s the first thing you do when visiting a website. Mostly, looking around and clicking, by clicking on something it does some actions, right? Maybe take you to another page or show you some popups and so on.

My point here is, in any application there a is a bunch of pages to show different information that you can navigate to/from. e.g. you have a portfolio site to show off yourself, how’d you do that? probably the best way is to maintain several pages/components to show different information about you. such as about meskillsprojects etc.

Let’s say, you want it to build that with React js. You’d like the visitor to learn about you, it’s important to keep things organized, you don’t want them to be confused. Keeping your app sweet and simple is the key. One way to that is to break down your app into components. e.g. keep Home to give a brief introduction about yourself, then About usProjects, etc pages to show respective info.

But you got to use some kinda navigation system, right?

So, In react you can easily implement navigation using a package called React Router.

Getting started with React Router

We’re gonna built a simple routing project with react-router-dom.

application demo

To begin with, let’s create a react application using [create-react-app](https://github.com/facebook/create-react-app).

npx create-react-app app-name
cd app-name
npm start

After that, on another tab/ctrl+c on the current tab on your terminal, install react-router-dom using this command,

npm install react-router-dom

How to Setup React Router v5 using React Hooks

React Router library makes the navigation experience of the client in your web page application more joyful, but how?!

React Router, indeed, prevent the page from being refreshed. Thus the blank page resulted from a refreshed page is not displayed while the user is navigating and routing through your web. This tool enables you to manipulate your web application routes through provided routing components and dynamic routing while the app is rendering.

How to start:
You need a React web app, to get started. If you don’t have, install create-react-app and launch a new project using it. Then you need to install react-router-dom, applying either npm or yarn.

npm install --save react-router-dom
yarn add react-router-dom

Now all the required components are installed. We are enabled to add any component to the App.js inside the router to build our unique web page. All these elements are the router children to which we specify their path. For instance, I add the components of Homepage, About, and Products inside the router where one can navigate through them. Also, React Router allows us to redirect our clients by a simple click on a button. To this purpose, import the Link to your component, define an onclick function for the button and redirect it to your intended path.

These are not all. There are other features in React Router. If you want to know how to install and benefit from it, join me in this YouTube video to decode the solution. I create the above-mentioned app and its components and explain all the features that we can use to improve it:

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

  • React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
  • React.js and React Native have similar syntax and workflows, but their implementation is quite different.
  • React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
  • React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

  • United States- $120,000
  • Canada - $110,000
  • United Kingdom - $71,820
  • The Netherlands $49,095
  • Spain - $35,423.00
  • France - $44,284
  • Ukraine - $28,990
  • India - $9,843
  • Sweden - $55,173
  • Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

  • Conduct thorough candidate research, including portfolios and areas of expertise.
  • Before you sit down with your interviewing panel, do some homework.
  • Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
