• Push Notifications and Engagement
  PWAs can send push notifications, allowing businesses to engage with their users more effectively. Push notifications enable real-time communication, notifying users about updates, new content, or personalized messages.
  This proactive engagement helps businesses stay connected with their audience, increase user engagement, and drive repeat visits.
  By offering push notifications, PWAs enhance the user experience by keeping users informed and engaged with the application even when they are not actively using it.

Key Features of PWAs

Here are some core features that mobile app developers must include in your progressive web app:

• Responsive Design and Adaptability
  One of the key features of PWAs is their responsive design and adaptability. PWAs are built to provide a consistent user experience across various devices and screen sizes, including desktops, tablets, and smartphones.
  The layout and content of the PWA adjust dynamically to fit the user's screen, ensuring optimal usability and engagement.
• Service Workers for Caching and Background Processing
  PWAs utilize service workers, a powerful technology that enables caching and background processing.
  Service workers allow PWAs to cache essential data and resources, making them available even when the user is offline or experiencing a poor internet connection.
  Additionally, service workers can perform background tasks like updating content or sending push notifications, enhancing the overall performance and functionality of the PWA.
• App Shell Architecture
  App Shell architecture is used in PWAs to deliver fast and reliable experiences. The app shell is a minimal HTML, CSS, and JavaScript framework that loads quickly and serves as the foundation of the PWA.
  By separating the core application structure (app shell) from the dynamic content, PWAs can load the essential components instantly, providing users with a snappy and responsive interface.
• Secure Connections with HTTPS
  PWAs prioritize security by requiring a secure connection through HTTPS. This ensures that data transmitted between the PWA and the user's device remains encrypted and protected from unauthorized access. By utilizing HTTPS, PWAs provide a secure environment for users to interact with the application, building trust and safeguarding sensitive information.
