Quasar is a framework for building Vue.js-based web applications, so applications written in Quasar can be described as web or browser-based applications. Quasar provides a rich set of pre-built UI components and a responsive design system that allows developers to create applications that work well on desktop and mobile devices.

Quasar also provides a way to package web applications as hybrid mobile applications using tools like Cordova or Capacitor. When packaged as a hybrid application, the application's UI is rendered using a web view, which can sometimes result in performance issues and inconsistencies with the platform's native look and feel. However, like other hybrid frameworks, Quasar provides a set of plugins that allow developers to access native device features like camera, GPS, and sensors, which helps to ensure that the applications are able to offer a level of functionality similar to native applications.

Therefore, applications written in Quasar can be considered as hybrid applications when packaged as a mobile application, and web or browser-based applications when used in a desktop or mobile web browser.

Compilation

When building a Quasar app, the web technologies are used to build a web application, which is then compiled into a native app for the target platform.

Quasar uses the Vue.js framework as its core, and adds additional functionality to build cross-platform applications. Quasar supports multiple platforms, including iOS, Android, Desktop (Windows, macOS, and Linux), and PWA (Progressive Web Apps).

When building for each platform, Quasar uses a set of platform-specific tools to compile the web application into a native app. For example, when building for iOS, Quasar uses Xcode and the iOS SDK to create an iOS app, and when building for Android, it uses the Android SDK and Gradle to create an Android app.

Quasar also includes a set of UI components, called Quasar Framework, that provide a consistent set of user interface controls that work across all the supported platforms. The UI components are built using web technologies such as HTML, CSS, and JavaScript, and are styled to look and feel like native controls on each platform.

Overall, Quasar compiles web technologies such as HTML, CSS, and JavaScript into a native app for the target platform using platform-specific tools. The framework also includes a set of UI components, called Quasar Framework, that allow developers to build shared user interfaces across multiple platforms. Since Quasar uses native compilation to create the app, the performance and user experience are typically faster and smoother than that of a hybrid app that uses a WebView.

Offline Capabilities

• Local data storage: Quasar apps can use various local storage mechanisms such as IndexedDB and LocalStorage to store and retrieve data when there is no internet connection available.
• Caching: Quasar apps can cache data locally, allowing them to access previously downloaded content without an internet connection. This can improve app performance and reduce data usage.
• Background Sync: With the Quasar PWA plugin, apps can periodically synchronize data with the server in the background, even when the app is not actively being used.
• Service Workers: Quasar apps can use Service Workers to provide offline support for web applications. Service Workers allow apps to cache resources such as HTML, CSS, and JavaScript, enabling them to work offline.
• Offline UI: Quasar provides the ability to design and implement offline user interfaces that are displayed to users when the app is offline. This can be useful for providing users with relevant information and functionality, even when they are not connected to the internet.

Overall, Quasar provides various capabilities and tools to create offline-first web, desktop, and mobile applications that provide a seamless experience for users, even when they are not connected to the internet. However, it is important to note that some of these capabilities may require additional configuration and setup, especially when creating Progressive Web Applications (PWAs).
