In this tutorial, we will explore how to make your Angular app offline-ready by leveraging the power of Progressive Web Apps (PWAs). We will cover the basics of PWAs, the benefits they offer, and how Angular can be used to build them. We will then delve into the concept of offline capabilities, focusing on service workers and their role in caching assets and handling offline requests. We will also discuss strategies for optimizing performance, including lazy loading and code splitting. Lastly, we will explore how to configure and handle push notifications in your PWA, as well as testing and debugging techniques for offline functionality.

Animated.View is the built-in React Native way to animate a view's opacity, transform, position, and other supported styles. It is still useful for simple microinteractions: fade-ins, scale feedback, loading motion, card entrance animations, and small transitions that do not need complex gesture logic.

For heavy gesture-driven UI, shared element transitions, and UI-thread worklets, React Native Reanimated is usually the better tool. For simple screen polish, the core Animated API is still enough.

Hermes is the JavaScript engine optimized for React Native. In modern React Native and Expo projects, Hermes is the default path for most apps, so the real question is no longer "How do I turn Hermes on?" It is "How do I confirm Hermes is working, benchmark the app properly, and avoid update/runtime mismatches?"

Video compression is one of the easiest ways to reduce upload time, storage cost, and feed latency in a React Native app. It matters for social networks, chat apps, marketplace listings, short video apps, fitness apps, and any product that lets users upload media from the camera roll.

Perceived performance is how fast an app feels to the user. A screen can take the same amount of time to load, but feel much faster when it shows immediate feedback, preserves user work, avoids blank states, and explains what is happening.
