PWAs gain their popularity during the last years, so a lot of users try to find the easiest and effective method of creating this type of apps. 

👉If you still thinking of its profitability, we prepared for you some articles according to the topic of PWA and its benefits and more you can read on our blog.👈


So if you are a newbie in PWA development, the easiest way is to start with Your First Progressive Web App Google’s guide.

But if that is not your first PWA, and if you are searching for some tools that can help you and save a lot of time, this article is for you!


Well, let’s start with frameworks!

Step 1: Use React (a framework from Facebook)👨‍💻

React is known as a JavaScript library for building user interfaces. It is supported and maintained by Facebook and Instagram and a community of individual developers and companies.

There are some kinds of React, but in Omertex we use ReactJs cause: 1) we can trust its creators and millions of people around the world, who use this kind and create their apps without any circumstances;

2) we can easily convert PWAs in native apps or desktop apps, using ReactNative.

Each component, the user interface is created of, can be displayed both on the app or browser (using ReactNative or Node.js, respectively). 

Components are made of JavaScript and it’s easy to use them again. ReactJS supports both regular and JSX JavaScript (JSX is an XML-like syntax for writing JavaScript code).

Step 2: Use Polymer templates from Google📃

Polymer Project was created to make “the web better”. According to high modern standards, libraries and tools, they make it possible to save your time, during PWA creation. Google’s open-source project often is updated to synchronize new apps and existing ones.

What concerns apps’ design, Polymer template automatically uses Google’s Material Design.

Step 3: Create dependency graphs using Webpack 👀

Polymer is a great start. The further process and code are up to your skills, or skills of your team. 

For the next actions, you can use a Webpack – a special package of modules for Apps running on JavaScript.

Thanks to Webpack, the creation of dependency graphs became much easier. You don’t need to link to all the JS files at the bottom of an HTML page; the number of calls to the server decreasing and the speed of your final product increasing.

Step 4: Manage Model-View-ViewModel(MVVM) bindings between HTML and JSd HTML with Knockout🙌

Knockout is a platform that runs just on JavaScript, which can work with numerous platforms and browsers.

It’s an open-source free tool, that would be helpful for MVVM bindings. Thanks to Knockout, you can simplify the process of JavaScript coding. The benefit of the Knockout library is that it can also integrate with existing websites without any remarkable changes.

If you are a newbie in PWA development, it will be easier for you to work with it due to a package of attributes, that you would have to write Knockout is easy enough for a novice developer to learn quickly. And it comes with many attributes that would otherwise need to be written in competing frameworks.

Step 5: Use AMP from Google to compress Images / JS🌆

AMP (Accelerated mobile pages) is an open-source HTML framework. It allows you to load web pages quickly in circumstances of low network speed. 

Moreover, Google supports AMP Cache Lastly, Google supports AMP Cache for AMP items that can be used for free. In addition, Google raises AMP-based sites in search results.

Step 6: Test code with Lighthouse from Google⌨

The last part but a significant one is testing of your app. 

In this way, Google’s Lighthouse is an open-source, automated tool for improving the performance and quality of your web apps. You can install it as a Chrome plugin (moreover, you can find a guide there).

After Lighthouse is installed, you can get the report, which contains a lot of details. 

It should give you information about:

  1. Page speed (ideally high speed)
  2. The site is a progressive application.
  3. Full security of the network connection
  4. Possibility to download an app
  5. The user-installed app will update automatically
  6. The same design for all devices
  7. Mobile-friendly design

Each of these points give you additional information about specific technologies you can add or change to improve your PWA performance.
