Creating PWA Applications

In one of our previous articles, we described the advantages of using PWA applications. Progressive web applications require fewer hardware resources, have faster download speeds, and can function offline. Creating PWA applications can be more accessible and functional compared to developing mobile applications.

From a technical standpoint, creating PWA applications is similar to web development, but it has some distinctive elements.

1. Key components of PWAs:

Web App Manifest: This allows for saving necessary data and discarding information that won’t be used in the future. It also contains program data.
Service Workers: These provide key advantages such as offline functionality and push notification capabilities.
Application Shell Architecture: Also known as the app shell, it’s a shell for the application that enables quick loading using Service Workers.

2. Distribution methods for progressive applications.

Unlike native applications, PWA applications have a broader range of distribution channels:

Distribution Channels	Native Applications	PWA Applications
App Stores	Google Play Store, Microsoft Store, Samsung Galaxy Store, etc.	Google Play Store, Microsoft Store, Samsung Galaxy Store, etc.
Marketplaces	None	PWA Builder App Gallery, PWA Directory, etc.
Hosting Platforms	None	Netlify, Vercel, Firebase Hosting, GitHub Pages, etc.
Content Delivery Networks	None	Cloudflare, Fastly, Akamai, etc.
Social Networks	Promotion through websites, social networks, online communities, etc.	Promotion through websites, social networks, online communities, etc.
QR Codes and Hyperlinks	None	Creation of QR codes, hyperlinks to the application
Email Campaigns and Subscriptions	Promotion through informational materials and email	Promotion through informational materials and email

Features of PWA Applications:

Caching and Offline Mode: Thanks to the use of Service Workers, PWA applications can cache resources and work in offline mode. This allows users to continue interacting with the application even when temporarily disconnected from the internet.
Push Notifications: With the help of Service Workers, PWA applications can send push notifications to users’ devices, even if the application itself is not running. This helps keep users engaged and informed. Developing mobile applications does not typically involve offline functionality..
Automatic Updates: PWA applications can be automatically updated without the need to install updates from an app store. This allows for quick bug fixes and the addition of new features without inconvenience to users. Developing mobile applications requires downloading and installing an update file.

Several use cases where creating a PWA application is the optimal alternative to developing a mobile application:

The internet is the primary channel for generating or communicating with clients.
Fast application loading is a key competitive factor.
Real-time communication with clients is necessary.
SEO optimization is important for attracting clients.
Push notifications are required.
