Performance is a critical factor for Progressive Web Apps (PWAs) because they are expected to work smoothly on a variety of devices and network conditions. Like:

Efficient Asset Loading: Use techniques like code splitting, lazy loading, and caching to ensure that only necessary assets are loaded and they are loaded efficiently.

Server-side Rendering (SSR): SSR can improve the initial load time by sending a fully rendered page to the client.

PRPL Pattern: The PRPL (Push, Render, Pre-cache, Lazy-load) pattern can help structure and optimize your app for maximum performance.

Roman Sydorchuk I hope that help!

Mohammad Imam

A few steps

1. Minimize Network Requests

2. Optimize Images

3. Prioritize Above-the-Fold Content

4. Use Service Workers for Offline Support

5. Optimize JavaScript Execution

6. Implement Code Splitting and Lazy Loading

7. Monitor and Analyze Performance

8. Responsive Design and Layout

Good luck
