We add a testing functionality to our created service worker file by using a default console.log(“ “) command, create a new production build of the app, and check the console. Lighthouse will give us an improved PWA score because of our added service worker functionality. You can get creative and write more complex service worker code, depending on what functionality you desire.

Let’s compare the most popular frameworks like React.js and Angular.js. The launch of the powerful and easy-to-use PWA enabled Starbucks to expand the business successfully. The company doubled the number of daily active users and boosted the orders from desktops to be nearly the same rate as orders from smartphones. StackOverflow, the largest community of programmers, has more than 248,000 questions within the tag #reactjs. Broaden your knowledge about proven React tools and practices by reading our detailed article.


For this example, we will be using a static name, meaning that our assets will not change or require updating. Once a user has added the web app to their home screen, they will be able to re-engage with your application immediately from their device, without having to directly open the browser. A progressive web app can be installed on the device’s home screen, making it readily available. By definition, a progressive web app must work on any device and enhance progressively, taking advantage of any features available on the user’s device and browser. This is the code repository for Progressive Web Apps with React, published by Packt.

Service workers are reasonably independent and influential elements of PWA. They operate as a representative between the browser and the network. A service worker is considered a blueprint for an architectural project. A detailed foundation will be essential for deploying Progressive Web Apps in 2026 the project. Whether you are just beginning or looking to develop web apps, here is a best web development course that would surely help candidates to procure jobs in the Market. You can also check the article on Vue vs React to check which JavaScript framework is best.

Also, you will need maskable icons that allow web developers to specify a full-bleed icon that the user-agent will crop to match other icons on the device. It enables Android developers to get rid of the default white background around their icons and use the entire provided space by generating adaptive icons. Simply put, service workers manage your PWA in the background, overlooking all the features that don’t require user interaction. The relatively new technology has 36% higher conversion rates than native apps.

A user story is a description of a specific feature of an application, framed from the perspective of one of our users. also now supports previewing and customising the Splashscreen for your manifest, a handy time saver. With some work, it’s possible to write PWAs with React that do perform well on real devices under limited network conditions as demonstrated by

This could also mean that a majority of users only stick to a few apps and uninstall the apps that they don’t need. Mobile App Report revealed that more than half of the U.S. smartphone users download zero apps per month. This may raise some eyebrows, given the fact that apps account for 57 percent of users’ time spent on digital media. A user running the application without an Internet connection will simply result in the application shell and the offline warning being displayed — an improvement over Chrome’s prowling t-rex. Once the user has established a network connection, we disable the warning and retrieve the latest data. This is used to determine whether any changes have been made to our cached assets.

Progressive Web App Examples Built With React

We’ll do this by defining a schema in the /sanity/schemas folder. Next, we’ll create a new Sanity project inside of this folder. Sanity is also a backend-as-a-service meaning that it hosts a service for your frontend to call so that you can request content directly from Sanity without having to write any backend code. A screenshot of Sanity StudioLastly, Sanity helps you distribute this structured content to any type of technology — including PWAs. …and then creates a UI for you and your editing team to rapidly create structured content items. So to me, if your site can do all these, then there’s no question about it — it’s definitely a progressive web app, and it’s what we’ll be making in this article.

But if you want to adapt your logo to as many devices as possible, you can use additional icons. React supports JSX, a syntax extension that allows writing HTML-like syntax in your JavaScript code. However, you are not bound to use JSX in React – it is just a simpler way for your convenience. So, you can use plain JavaScript and HTML & CSS to build a powerful PWA with React. React uses virtual DOM to make changes to the UI without redrawing the whole page and experiencing rendering issues.

However, other than that, any frontend framework will work just as well for a PWA. The first problem is that many users will be visiting your web page under poor network conditions. They may be a Silicon Valley technocrat on their iPhone in a coffee shop with bad WiFi, or they may be a Bangladeshi villager in a remote location. Either way, they will not stick around if your site isn’t optimized for them, for everyone.

Before you can begin coding, you need to set up your project. Let’s start by ensuring you can use React (if you’re already familiar with coding in React, you can probably skip this section!). You need to use Node.js with any development using web frameworks such as Angular, React, or Vue — especially if you wish to use libraries and packages to assist in developing your project. The default configuration includes a web app manifest located atpublic/manifest.json, that you can customize with details specific to your web application.

Installation And Easy Discover

I do realize there are desktop ports of React Native available, but most aren’t officially maintained by the React team and have various gaps that you will need to address yourself. There is always a nontrivial cost to learn a new technology and train others on it. Both PWAs and React Native have their steep learning curves when you want to create a great user experience (especially at the critical last-mile), so keep this detail in mind as a factor.

  • Also, you can discover one of our favorite PWA case studies.
  • Progressive Web Apps take advantage of new technologies to bring the best of mobile sites & native apps to users.
  • These companies know how to make a React progressive web application that is powerful and responsive.
  • Become familiar with the Workers CLI wrangler that we will use to bootstrap our Worker project.
  • It’s also worth noting there are other possible options like Vue.js and Svelte.js.
  • For an app to be a PWA, it must meet certain guidelines and principles as provided by Google.

Before we cruise to any other guide, let’s peek at the react PWA. React.js PWA tutorial that helps in the development of basics and advanced PWA react applications. Service workers are scripts that are executed by the browser.

You should see a stream of prompts in your command-line interface. It may take a few minutes, but if you can see this screen after the command, you have created the project. The service worker is only enabled in the production environment, e.g. the output of npm run build.

Step 1: Create A New React App

In terms of PWAs, this typically means creating a JavaScript-powered site . That’s right, they’re not part of some framework you have to download and install, they’re APIs that come with your browser, ready for use by default. What powers the most distinct features of PWAs are sets of individual web APIs that are already built into the browser.

When the user first visits the page, download those assets and then save them for later . Then, when the user reopens the application, instead of downloading the files again over the internet , we simply retrieve them from the user’s device . The advantage of React is that it is a beautiful and fun way to build frontend applications. If you pair knowledge of React with experience with PWAs, you’ll be about as future-ready as one can be in the fast-moving web development world.

Whenever you start building a React app, you can use templates offered by Facebook using the ‘create-react-app’ command with npm. Able to operate in the offline mode, PWAs are quite popular nowadays due to their capabilities to work smoothly in areas with low connectivity. Leveraging the front-end technologies such as HTML, CSS, JavaScript, etc. which are used to build PWA that delivers native app-like experiences over the web as well as mobile platforms. Progressive Web App has been the center of attention in the IT space.

Background_color – You can provide this property, which is used on the splash screen when the application is launched on slow networks. Downloading resources will take some time during the application’s initial load. These are still early days for progressive web apps, and cross-browser support is still limited, especially in Safari and Edge. However, Microsoft openly supports progressive web apps and should be implementing more features by the end of the year. One of the easiest wins with service workers is that we can improve performance with little to no effort. Comparing our website to itself before service workers were implemented, before we were retrieving over 200 KB upon page load; that is now reduced to 13 KB.

Getting Started

If you open it up, you can see that there are several folders already. We’ve not only installed React, but everything that React depends on–dependencies on dependencies. Just to reiterate, Node is a JavaScript runtime used to execute JavaScript outside of the browser, and npm is a method of managing modules of JavaScript code.

The next step is to get everything set up for our application, and create our basic folder structure with HTML and CSS. Once we start building our application, we’ll also see that solving these problems is still a challenge, but all very achievable with React. For now, don’t worry if this distinction doesn’t “click” yet. For now, the point is that push notifications will be an interesting challenge for our web application. In your command prompt, entering ‘npm start’ can spin up your application to a specific localhost url.

Our App Skeleton

The service worker sends HTTP requests to the server even if the web page is not working. This will allow us to complete our work without any extra steps. The service worker serves as a helper to React PWA in displaying content even offline.

If your website already has an application-like interface, applying the concepts of progressive web apps will only make it better. When assessing whether your next application should be a progressive web app, a website or a native mobile application, first identify your users and the most important user actions. Being “progressive,” a progressive web app works in all browsers, and the experience is enhanced whenever the user’s browser is updated with new and improved features and APIs. A study has shown that, on average, an app loses 20% of its users for every step between the user’s first contact with the app and the user starting to use the app.

PWAs create immersive user experiences that feel and function like mobile apps, yet are built upon web technologies and infrastructure. The default precaching strategy in Workbox in the create-react-app is cache-first. Now, you can open your app on your mobile phone and see a small install icon. Once installed, the app will be added to your device’s app drawer with the icon you’ve selected in the manifest.webmanifest file.

He is passionate about web technology and has been active in web development since 2010. With this, we have successfully implemented our application and now we need to launch it. To launch the application indevelopment version, use the command below. The final project sample is available in thisgithub repository, to track the progress in each step. You can also follow along with committed details provided at the end of each step. PWA stands for Progressive Web App, a type of application software that just looks and feels like an app.

Google has created a checklist on PWA, and you can assess your web app using Lighthouse. It is a tool located in the namely tab of Chrome DevTools. So, we discussed how to make a progressive web app using React. For more detailed information about adjusting your PWA, check the Web App Manifest guide from the World Wide Web Consortium.
