How to Build a React Progressive Web Application?

The introduction of React, with its focus on application efficiency and development simplicity, transformed the world of front-end development. A few years later, progressive web apps (PWAs) were developed and have once again revolutionized the world. PWAs are gaining ground on web and mobile applications in popularity and user experience.

In this Blog, we’ll review how to use these two technologies to Build a React Progressive Web Application. Reviewing React and PWA, and how to develop the latter using the former in quick succession.

What is a Progressive Web App?

Let’s review the fundamentals of Progressive Web Apps before moving on to the tutorial of React PWA

The concept of progressive web apps is fantastic despite its awful name. Using web technologies, you may create an app that works on all devices and form factors at once. It may be visited online and shown on your Android or iOS device’s home screen. This program has notification capabilities, an initial splash screen, and the ability to operate offline

PWAs may help your company save money. Building the same application utilizing three separate technologies (one for the web, one for Android, and one for iOS) is an alternative if you want to give your users an app experience.

When choosing this route, it is difficult to avoid a multiplication of expense and complexity. The team frequently becomes divided due to everyone working on a distinct stack. It’s typical to lose some level of concentration as a result. PWAs can be helpful in this situation since they are an attractive solution from both a developer and a resource standpoint.

The PWA technology provides the following six key advantages:

• A standard website loads slower than a progressive web app, which also installs and activates more quickly than a mobile app. With each subsequent visit, the page loads quicker because all static website assets are cached.
• Compared to other web or native solutions, progressive web apps are significantly easier to design and utilize. For instance, submitting them to the App Store or Google Play is unnecessary because apps may be installed directly from the browser.
• PWAs are cross-platform, meaning that if they are accessible through a standards-compliant browser, they work with all devices and operating systems.
• PWAs use cached data from prior sessions to provide flawless and uninterrupted performance if the network connection is unreliable or nonexistent. Your app will be accessible to users virtually everywhere.
• Due to their speed and simplicity, combined with all the essential features of native solutions, progressive web apps offer a fantastic user experience. A user can launch the PWA by tapping the icon on the home screen, just like with a native mobile app. Additionally, updates are downloaded in the background, unlike native programs.
• While PWAs don’t directly affect SEO rankings, a well-designed PWA has the potential to increase retention rates, lower bounce rates, and boost your web page’s overall SEO performance.

The React Progressive Web App Components

Now that we are getting closer to finding an answer, how do I use React to create a PWA? Let’s finish off with the final theoretical stage, PWA components, before starting our ReactJS PWA tutorial.

1. Service workers

Service workers are relatively independent and fairly influential elements of your PWA. They act as a delegate between the browser and the network. All in all, one can think of a service worker as a blueprint for an architectural project. You create a detailed foundation that will be necessary for deploying your project.

Simply put, service workers manage your PWA in the background, overlooking all the features that don’t require user interaction.

2. Web manifests

A JSON file called the web manifest specifies the specifications for how your PWA should look. It is required to configure the application name, primary colors, iconography, etc. Look for the “Generate the Manifest with Your App’s Details” part below, where we describe it with an example, to have a better understanding of what and how you can configure there.

Here are a few illustrations of the keys for the react manifests for progressive web apps

• name
• icons
• shortcuts
• background_color
• categories

3. Application shell

The application shell ensures the content loads quickly and consumes the least amount of data. Even without connectivity, it keeps the PWA fundamentals, including the interface, intact. The app shell is essentially the design of your interface.

Characteristics Of A Progressive Web App

Progressive web apps were created to provide the best user experience for mobile users of web apps and platforms. With the help of PWA technology, users may access a native-like app through a browser, instantly install it, utilize most native features, and use the app while offline. A progressive web app developer aims to make a website look like an app that is downloaded and installed on a smartphone, tablet, laptop, or PC.

Why Build Progressive Web Applications with React?

React is an open-source Javascript technology developed by Facebook in 2013 and creates scalable user interfaces. Well, doing so is a quicker and easier process. The advantages of utilizing React when creating Progressive Web Apps are listed below.

• Hot reloading: You can create web applications with React that are both enterprise-level and extensible. Do you know these apps stand out because they enable hot reloading? As a result, your program will continue to run while your developer makes changes.
• Code reuse: React adheres to the “learn once, write anywhere” tenet. It implies that you may develop code once and utilize it in various contexts.
• Well-Equipped: React has several libraries, boilerplates, and developer tools. All of this facilitates easier app testing, debugging, and design. You can pick the best choice based on the demands and requirements of your project.
• Easy to Learn: React is simple to read, unlike other JS frameworks or libraries. Your developer can use JavaScript to create HTML-like syntax because it supports JSX. A dynamic PWA can also be made utilizing JavaScript, CSS, HTML, and JSX.
• Scalable: Thanks to its scalability and performance, high-performing web apps can be created using React. Performance difficulties are a common problem for JavaScript applications. They have DOM manipulation in common. React, thankfully, makes use of virtual DOM. It implies that UI changes can be made without altering the entire page.
• SEO Friendly: Working with complex online apps may present SEO-related challenges. As a result, Google search will not display that particular section of your website. Good news: React takes advantage of virtual DOM. It will guarantee accurate indexing of the information on your website.
• Community support: A sizable community is available to you if you decide to build a Progressive Web Application using React. It comprises knowledgeable and responsible progressive web app development partners and designers who are always willing to assist their clients. This is why you must hire progressive web app developers.

How to Make a PWA with React?

Finally, this is the part where we’ll explain how to create a progressive web app. It’s simpler than you may think to create a progressive web app, and you can use almost any JavaScript framework. That being the case, why would you pick React? It’s fast, performant, easy to use, and VERY well-liked among developers, which is precisely why you would choose it to construct any other kind of progressive web app development services.

Step 1: Add a progressive web app manifest

Let’s begin by defining a web app manifest. It’s a JSON file informing the browser about your PWA and the actions it should do after downloading and installing it on the user’s desktop or mobile device. Google Chrome, Microsoft Edge, Firefox, Opera, and the Samsung browser all support manifests, however, Safari only provides a limited amount of support.

Add the manifest to your app once it has been made. To accomplish this, provide a link> tag on each page of your PWA.

Step 2: Add service workers

The service worker is a JavaScript file that handles network request interception, data caching, data retrieval from the cache, and push message delivery while running independently of the main browser thread. Service workers enable PWAs to manage network requests, cache them to improve performance, and guarantee offline access to the cached content.

Service workers rely on the Fetch and Cache APIs to guarantee the performance of offline apps. To serve resources from the cache when the network is down, the Fetch API intercepts network requests changes the answer, and serves resources from the cache. The cache in the browser has no bearing on the Cache API.

Additional technical details relating to service providers:

• Service workers exclusively operate over HTTPS to prevent “man-in-the-middle” attacks.
• A service worker must use postMessage() to communicate with the page because it cannot access DOM directly.
• Synchronous XHR and localStorage are not available to service workers.
• Google Developers has more information about enrolling, installing, and activating service workers.

Step 3: Test your PWA

Once everything is set up, it’s time to determine whether your application complies with PWA requirements. Google offers a formal tool for that purpose called Lighthouse. You need to install screening on your website using a Google Chrome extension. If the outcome is 100%, congrats! Your PWA-optimized app runs quickly. If it’s less than 100 percent, the service will let you know how to fix the issue.

Popular PWA Examples

Tinder

Tinder is one of the most well-known and effective instances of a progressive online application in 2022. To draw in more customers, the dating app decided to develop PWA. More swipes, profile changes, and time were spent per user session when a PWA was built as opposed to a native app. Tinder PWA also decreased load times from 11.9 to 4.69 seconds.

Starbucks

With its offline functionality, Starbucks PWA enables users to browse the menu and personalize their orders without constant Internet access. For clients who are constantly on the go and might not have access to the Internet, that is undoubtedly quite convenient. As a result, the new Starbucks PWA assisted the business in seeing a dramatic increase in the daily volume of orders placed by app users.

Instagram

The PWA for the social media platform Facebook owns is arguably one of the most close to the provider’s native app. Instagram is another fascinating example since developers have just updated its online interface. The New Stack claims it is no longer a PWA but a native app created with the as-yet-unknown Blocks technology.

Uber

PWA provided Uber with a solution to the problem of poor Internet access and potentially incompatible devices. Everyone can now access a light version of the service. Both the hungry customer and the diligent delivery rider benefit from it.
