The code shown later in this article is made using these libraries. In this case, the browser will receive these files from the Service Worker, without the need to make a request to your site.įor the convenient work with cache in SW, Google has developed a group of workbox libraries. For example, knowing that all your CSS and JS files don’t change, you can cache them. SW also allows you to cache and spoof requests that come to your website from the browser. Service Worker has its own lifecycle events. The key point is that the SW runs in the worker context and does not have access to the Document Object Model (DOM). A Service Worker is a script executed in the background, unable to block the JavaScript execution thread, and executed in a separate thread. In simple terms, it’s a layer between the browser and your website. But so far it has little in common with a real mobile app. Just simply adding the Manifest.json file makes browsers see your website as a PWA, and lets it be installed as a mobile application. You can find out more about its parameters in this article. It contains the name of your app, its icon, and other necessary information. The purpose of this file is to tell the browser that your website can be executed as a progressive application. Let’s take a closer look at each of them. You need to know that a modern PWA application consists of the following key elements: PWAs can’t work without observing these requirements. Important to know: Your website has to have an SSL certificate and support the HTTPS protocol.

How to make a PWAįirst, let’s see how to make a PWA to work with. Time to look into how you can actually create one. So the logical follow-up is to ask if there’s a possibility to take a PWA and make it look like a native app, publish it in the App Store and everything? There is! In fact, we’ve already mentioned it too and discussed its benefits and requirements. The point is, while PWAs are fast, far more lightweight than native applications, and often more flexible, they have a certain set of limitations that we discussed in the previous article, mainly connected with their inability to appear in app stores. Today is the time to go a bit deeper into technical details and show you how to make a native app out of a PWA in just a few steps. Some time ago we made an article about the business value and the essentials of the Progressive Web App technology.
