React offline storage

To make our app work offline, we need to get the web assets to work offline. Create React App already has the required boilerplate for making an app offline using service workers. Open src/index. js and change the line that says serviceWorker.

So, you can use plain JavaScript and HTML & CSS to build a powerful PWA with React . React has many developer tools, boilerplates, and libraries to make debugging, testing, and design easier. It offers a variety of options so you can choose the one that will suit your particular task the most.

In order for your PWA to be offline-capable, service workers pay a part in serving the content, but you’d also need to cache your page’s resources as well . To cache your page’s resources, first you need to plan out the size of your Cache Storage since there’s a limit to it.

Our app is caching its resources on install and serving them with fetch from the cache, so it works even if the user is offline .
