What Does  Magento PWA Development Mean?

Before we dive into the stages of Magento PWA development, let’s understand what PWA is and what it means to develop a PWA. 

So, What is PWA? – PWAs are a smart concoction of native apps and websites. With this combo, users can enjoy the premium features of both. Therefore, PWA development is all about getting the features of native apps and websites under one roof. All together these features result in a dynamic browsing experience on the app with a secure interface.

Like mobile apps, PWAs remain on the homepage of smartphones and function in low network conditions also. So, buyers don’t need to download and install the app. Due to their website-like nature, PWAs are more likely to be crawled by search engines which bring organic traffic to your web store. The approximate size of a PWA is around 1 MB which makes loading easy, by using minimum data.

Not only that, but PWAs also offer push notifications just like the native apps to keep in touch with buyers. Also, PWAs come with mobile optimized views with interactive UX and UI. All together these features result in a dynamic browsing speed on the PWA with ultra-security.

Now, have a look at the detailed steps of the Magento PWA development life cycle. 

How To Develop PWA on Magento? – A Step-by-step Guide

Magento PWA development stages

These 14 steps can help you to execute a thorough PWA development on Magento. So, let’s dig in. 

Step 1: Analyze The Requirements And Make a Blueprint 

Preparing the blueprint is essential to kickstart any development project. In the Magento PWA development life cycle, you have to start with a to-do list. For developing PWA on Magento, we will recommend a well-known and simple practice here. But to ensure that you are getting the most out of PWA, you first need to understand and analyze the requirements of PWA. 

For this, you will have to read about different PWA Storefront for Magento 2 thoroughly and list down the features you want for your store. Also, you must have specific and realistic expectations from PWAs.

Step 2: Get SSL Certification To Serve Over HTTPS

Once you complete your research work, you step onto the premise of web app development. Here, the first step is to get an SSL certificate because HTTPS is an essential element of PWAs. The best way of getting an SSL certificate is to purchase it from a domain registrar. You can later configure this while hosting. 

Step 3: Form HTML Website With Boilerplate 

Now, you are at the core part of the Magento PWA development life cycle – here, you have to fulfill another prerequisite of PWA – the HTML website. For this, you can take the help of any boilerplate that the google developers offer. If you are a beginner, we will recommend you not to create your own. In case you want to create your own boilerplate, you can do that using JS, HTML, and CSS. For Magento, PWA development tries to keep this skeleton HTML website as simple as possible. 

Step 4: Develop Application Shell And Add The Functions 

Next, it is time to gather data to add functions to the HTML website. While doing that put more emphasis on the application shell since this will be the first visible element to a user. 

Make sure that the app shell loads really fast so that the users don’t have to stare at a blank screen. So, before focussing on other functionalities, make the application shell progressive.

Step 5: Develop Service Worker File For Offline Cache

Offline functionality is the main USP of PWAs and developing service workers provide the required support for offline functionality. A service worker is typically the proxy between the web application and network and it runs throughout the backend. Due to the cache of service workers, the users are able to view the preloaded pages in offline mode.

Remember: Put the service worker file in the root folder. Also, check whether the browser you are planning to launch Magento PWA supports service workers or not. Service worker files are allowed on almost all the HTTPS web pages. As you are already getting the SSL certificate, you will not have to face problems regarding service worker files. 

Step 6: Add Web App Manifestation

Web App Manifestation - Magento PWA development

Once a service worker file is prepared, you need to move towards developing a manifestation file. It is basically a JSON file to provide the meta-information about your web app. Also, it allows your web app to function in full-screen mode. The information related to the icons (color, short name and full name of the icon, etc) along with screen orientation and themes of your web app is stored here. In a nutshell, this step is the pre-designing stage. 

For Magento PWA development, you can easily get the manifestation file with Web App Manifest Generator from the file base app. Alternatively, Web Starter Kit can help here. Presently, chromium-based browsers and Firefox actively support web app manifestation. Ms. Edge is planning for the same while Safari has no plans of implementing it yet.

Step 7: Add UX/UI Designs 

Here comes the stage to plug in responsive designs on your web app. While developing PWA Storefront for Magento 2, remember that PWAs are designed with a user-first approach. UX and UI of PWAs include the following touchpoints:

  • A design that loads in the shortest possible time
  • Dedicated pop-up screen
  • Easy navigation with simple fonts
  • Catchy banners or rotating carousel on the homepage
  • A compact homepage
  • Simple and understandable icons
  • Smart placements of CTA buttons
  • Complete full-screen accessibility

While designing the homepage, category page, or product page, you are free to experiment. However, simplicity is the key to success in Magento PWA development. You can use Adobe XD or sketch or photoshop to design your PWA. You can also try Cenia pro theme to design your PWA – Check the demo or get it from Google PlayStore

Step 8: Create an “Add To Homescreen” Banner 

To allow a PWA on the home screen, the prerequisites are

  1. A valid manifestation file with a short name
  2. HTTPS service
  3. A valid URL
  4. A PNG or JPEG icon
  5. Service worker file
  6. 2 user visits within 5 minutes

For this, you can take the help of any sample banners available on the internet.

Step 9: Configure Push Notifications

Towards the end of the Magento PWA development life cycle, you have to move on to defining the user engagement and re-engagement. Push notifications can be configured using Firebase Cloud Messages. Once you complete the coding and checking parts, you can trigger the Firebase Cloud Messages. Also, you can use terminal CURL for sending notifications to users.

Step 10:  Register On Service Worker

Now, you are almost done with the setups – so, use the browser navigator library to register on the service worker. This is just to make sure that you are serving this file from the root directory. As a result, the service worker can control all the requests that come from different pages from the same domain.

Once you have registered as a service worker, test whether it is successfully loading or not. You may have to turn off your internet connection for this. After successful loading, move on to the next step. 

Step 11: Deploy It To Firebase and Install The App

Firebase offers simple storage use, hosting, and push notification along with other benefits. So, don’t skip this step. Now, go to the app URL and load it twice. By doing this, you can get the ‘add to home screen feature. Just add this on mobile or desktop to access the PWA Storefront for Magento 2 right from the icon.

It is possible that the QA test is too costly, but to avoid further collapse of the web app, the QA test is essential.

Step 13: Audit Your PWA With Lighthouse

PWA Audit on Lighthouse

In the final stage of Magento PWA development, use Lighthouse extensions from Chrome DevTools. It will run PWA again in different situations and tally its results. Based on the performance of PWA, it will obtain a score out of 100. Not just that, it offers you tactics to improve your score using best practices.

However, in the last stage of the Magento PWA Development Life Cycle, you don’t need to launch the PWA on Google Play Store or App Store.
