Understanding the Core Concepts of PWAs

Before diving into the development process, it’s crucial to understand what makes Progressive Web Apps unique. PWAs are designed to work on any platform that uses a standards-compliant browser, including both desktop and mobile devices. Some of their key features include:
– Fast loading times: PWAs are optimized for speed, ensuring that users can access content quickly, even on slow internet connections.
– Offline capabilities: With service workers, PWAs can load cached content when there’s no internet connection, enhancing the user experience.
– Push notifications: PWAs can send notifications to users, similar to native apps, helping in re-engaging users.

Setting Up Your WordPress for PWA Development

Testing and Optimizing Your PWA

After implementing the desired features, testing becomes an indispensable step. This includes checking the PWA on various devices and browsers, ensuring offline functionality works as expected, and making optimizations based on performance feedback.

Performance Considerations
