How to develop a progressive web application with React?


Tech giants like Google and Microsoft have been leading the way in progressive web applications (or PWAs) for 4 to 5 years. Now, PWA has become a must-have technology for large businesses and small startups. Twitter, Starbucks, Google, and AliExpress use web app builders to improve their online image.

PWA is a web application that captures the benefits of native and web applications. It provides hardware functions and is included in the main body of cross-platform applications. Compared to native applications, its creation and maintenance are faster, simpler and less expensive.

PWA supports functions that are not accessible for normal sites. It integrates offline work, push notifications, access to geographic location, camera, microphone, etc. PWA can even run outside of the browser, using a local application shell that can be sent on startup.

  • React is the sixth frequently starred open-source repository on Github at the time of writing.
  • StackOverflow, the largest community of programmers, has over 327,847 questions in the tag #reactjs at the time of writing this information.

Configure web applications

The manifest.json is linked in the public / index.html file:

Note: The use of% PUBLIC_URL% in the above tags. It will exchange with the URL of the public folder during development. Also note that only files that are in the public folder can be extracted from HTML.

Having a manifest.json is required by Chrome to add your PWA to the home screen.

The serviceWorker.js registers our service worker file. To answer your question, where will the worker file be registered? The file will be generated with CRA when creating the application, i.e. when creating for production:

npm run build

Explaining the component of the file, let’s go:

  • The command generates the project and stores it in the build folder.
  • All js and css files are owned by the static folder.
  • The index.html is the main page that loads all of the React files stored in the static / js folder as well as the CSS that is stored in the static / css folder.
  • In the service-worker.js file, all of the service worker code is stored.
  • All files that the service worker caches in an array are maintained by the precache-man aifest. *. Js file.
  • In order for everything to go as planned, you need to load the build folder in the browser, but you will need a browser first. Install the http server
  • The next step is to add start in the scripts section of package.json.

File component

PWA test

After creating a React PWA. The next step is related to testing the application.

To run the application in production mode, enter the following commands shown in the figure below:
