React Router Tutorial: Redirect Like a Pro
Naive React routing increases risk and maintenance. This tutorial provides a full exploration of routing approaches, achieving an elegant solution that seamlessly fits into any React code base.
React Router is the de facto React page switching and routing solution. React Router was one of the first popular, open-source projects around React back in 2014 and has grown along with React to a prominent place within React’s ecosystem.
In this React Router tutorial, I start with a key concept and explain my choice of routing library. I then detail how to create a simple application with just enough programmatic logic to showcase various routing features. Lastly, I focus on implementing an elegant, secure, and reusable component to achieve a minimally intrusive and low-maintenance routing solution. The resulting routing code comports with React’s coding guidelines and style for a seamless fit within any recent React application.
Declarative routing is the coding style used within React and React Router. React’s declarative routes are components and use the same plumbing available in any React application. Since routes are components, they benefit from consistent approaches.
These routes associate web addresses with specific pages and other components, leveraging React’s powerful rendering engine and conditional logic to turn routes on and off programmatically. This conditional routing allows us to implement application logic to ensure our routes are correct and adequately secured.
Of course, any router is only as good as its library. Many developers don’t consider quality of life when choosing a library, but React Router v6 delivers a bevy of powerful features to simplify routing tasks and should be the React routing solution of choice.
What makes React Router the best compared to other routing libraries?
Developers who are using the previous version, React Router v5, should know about three key changes to React Router v6:
<Switch>
component has been renamed <Routes>
.useRoutes()
hook replaces react-router-config
for defining routes as plain objects.<Routes>
must be a <Route>
. This can break some previous methods for organizing and composing routes.The remainder of this article explores various v6-compatible patterns and ends with our ultimate and most elegant route composition. For more about upgrading from v5 to v6, check out the official migration guide.
Every great React tutorial needs a basic chassis to showcase its desired features. We expect that your development system has npm installed. Let’s create a simple React project with Vite—there’s no need to install Vite separately—that provides our base React app structure, a standalone web server, and all necessary dependencies:
npm create vite@latest redirect-app -- --template react-ts
This command creates our basic app using TypeScript.
React Router redirects users to pages within the client according to associated web addresses. An application’s routing logic includes general program logic, as well as requests for unknown pages (i.e., redirecting to a 404 page).
Since React generates a single-page application (SPA), these routes simulate old-school web applications with separate physical or file-based routing. React ensures that the end user maintains the illusion of a website and its collection of pages while retaining the benefits of SPAs such as instant page transitions. The React Router library also ensures that the browser history remains accessible and the back button remains functional.
React Routes provide access to specific components with an SPA and thus make information and functionality available to the end user. We want users to access only features authorized by our system’s requirements.
Whereas security is essential in our React client, any secure implementation should provide additional (and arguably primary) security features on the server to protect against unauthorized client malfeasance. Anything can happen, and savvy browser users can debug our application via browser development tools. Safety first.
A prime example includes client-side administrative functions. We want these functions protected with system authentication and authorization plumbing. We should allow only system administrators access to potentially destructive system behaviors.
There is a broad spectrum of expertise within the React developer community. Many novice React developers tend to follow less elegant coding styles regarding routes and associated secure access logic.
Typical naive implementation attributes include:
useEffect
React hooks to accomplish page redirection where unauthorized page access is detected.A naive routing component implementation might look like this:
import { useContext, useEffect } from 'react'
import { Link, useNavigate } from 'react-router-dom'
import { UserContext } from '../UserContext'
export default function NaiveApproach() {
const { loggedIn } = useContext(UserContext)
const navigate = useNavigate()
useEffect(() => {
// Check if the user is logged in (after the page loads)
// If they're not, redirect them to the homepage
if (!loggedIn) navigate('/access-denied')
})
return (
<div>Page content...</div>
)
}
An application would use this routing component like this:
export default function App() {
return (
<Router>
<Routes>
{/* Method 1: Using `useEffect()` as a redirect */}
<Route path="/naive-approach" element={<NaiveApproach />} />
</Routes>
</Router>
)
}
This approach is often implemented but should be avoided, as it wastes system performance and annoys our user base. Naive routing will do three things:
useEffect
hooks could potentially run before the redirect happens.We want to make our secure routing more elegant. Three things that will help us achieve a better implementation are minimizing code maintenance, centralizing secure routing logic to minimize code impact, and improving application performance. We implement a custom ProtectedRoute
component to achieve these goals:
import { ReactNode } from 'react'
import { Navigate } from 'react-router-dom'
/**
* Only allows navigation to a route if a condition is met.
* Otherwise, it redirects to a different specified route.
*/
export default function ConditionalRoute({
condition,
redirectTo,
children,
}: ConditionalRouteProps): JSX.Element {
return condition ? <>{children}</> : <Navigate to={redirectTo} replace />
}
export type ConditionalRouteProps = {
/**
* Route is created if its condition is true.
* For example, `condition={isLoggedIn}` or `condition={isAdmin}`
*/
condition: boolean
/** The route to redirect to if `condition` is false */
redirectTo: string
children?: ReactNode
}
Our application code requires adjustment to make use of the new ConditionalRoute
component:
export default function App() {
return (
<Router>
<Routes>
{/* Method 2: Using ConditionalRoute (better, but verbose) */}
<Route
path="/custom-component"
element={
<ConditionalRoute condition={isLoggedIn} redirectTo=”/”>
<CustomComponentPage />
</ConditionalRoute>
}
/>
</Routes>
</Router>
)
}
This implementation is markedly better than the easy, naive solution laid out earlier because it:
Although this implementation is better than others, it is far from perfect. The usage style seen in our application code sample tends to carry more code bloat than we like and is our motivation to write an even more elegant solution.
We want a truly epic and higher-order implementation that reaches the pinnacle of highly componentized route security, nimble parameter usage, and minimal impact on pages requiring routing. We introduce our elegantly written and lowest-impact component, the GrandFinaleRoute
:
/** A higher-order component with conditional routing logic */
export function withCondition(
Component: FunctionComponent,
condition: boolean,
redirectTo: string
) {
return function InnerComponent(props: any) {
return condition ? <Component {...props} /> : <Navigate to={redirectTo} replace />
}
}
/** A more specific variation */
export const withLoggedIn = (Component: React.FunctionComponent) =>
withCondition(Component, useContext(UserContext).loggedIn, '/home')
This secure routing component not only meets all of our requirements, but also allows for an elegant and concise usage without our page components:
const GrandFinaleRoute = withLoggedIn(HigherOrderComponentPage)
export default function App() {
return (
<Router>
<Routes>
{/* Method 3: Using a higher-order component */}
{/* (The best of both worlds!) */}
<Route path="/grand-finale" element={<GrandFinaleRoute />} />
</Routes>
</Router>
)
}
The GrandFinaleRoute
is concisely coded, resource-efficient, and performant, thus achieving all of our goals.
Application routing implementations can be coded naively or elegantly, like any other code. We have surveyed the basics of routing as a full exploration of the code for simple and complex React Router-based implementations.
I hope the final routing approach resonates with your desire to bring a beautiful, low-maintenance routing solution to your application. Regardless of the method, you can quickly grade your routing implementation’s effectiveness and security by comparing it to our various examples. Routing in React doesn’t have to be an uphill path.

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

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?
Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.
Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.
To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.
What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.
You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.
Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.
You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.
You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.
As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.
Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.
As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.
All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.
This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!
Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.
Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.
What advantages can you get from micro-mobility? Let’s take a deeper look into this question.
Micro-mobility can offer several advantages to the people on your campus, e.g.:

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.
Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.
In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.
A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.
And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.
Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.
It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.
We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.

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:
