- Responsive design: They adapt to any screen size.
- Installable: Users can add PWAs to their home screens.
- Push notifications: Engage users with timely updates.
Benefits of Using PWAs
PWAs provide numerous benefits, including:
- Improved user engagement through push notifications.
- Reduced development costs compared to native apps.
- Faster updates and maintenance.
- Increased accessibility across different devices.
- Better performance and reliability.
How to Build a Progressive Web App
Building a PWA involves several steps:
- Choose the right framework: Popular options include React, Angular, and Vue.js.
