📄️ Browser Console

Using the browser's console to print valuable program information is an integral part of the development process. The BrowserConsole utility class comes with a slew of features to enhance logging capabilities.

📄️ Lifecycle Listeners

The AppLifecycleListener interface enables external code to observe and respond to app lifecycle events. By implementing this interface, you can execute code at specific points during app startup and shutdown without modifying the App class itself.

📄️ Web Storage

Web storage is a fundamental concept in web development that allows websites to store data on the client side. This enables web applications to save state, preferences, and other information locally on the user's browser. Web storage provides a way to persist data across page reloads and browser sessions, reducing the need for repeated server requests and enabling offline capabilities.

📄️ Interval

The Interval class represents a timer that triggers an event with a fixed time delay between each triggering.

📄️ Browser History

The BrowserHistory class in webforJ provides a high-level API to interact with the browser's history. Browser history allows web applications to keep track of the user's navigation within the app. By leveraging browser history, developers can enable features like back and forward navigation, state preservation, and dynamic URL management without requiring full-page reloads.

📄️ Error Handling

Error handling is a crucial aspect of developing robust web apps. In webforJ, error handling is designed to be flexible and customizable, allowing developers to handle exceptions in a way that best suits their app's needs.

📄️ Namespaces

Namespaces in webforJ provide a mechanism for storing and retrieving shared data across different scopes in a web app. They enable inter-component and cross-session data communication without relying on traditional storage techniques like session attributes or static fields. This abstraction allows developers to encapsulate and access state in a controlled, thread-safe manner. Namespaces are ideal for building multi-user collaboration tools or simply maintaining consistent global settings, and let you coordinate data safely and efficiently.

📄️ Object and String Tables

The ObjectTable and StringTable provide static access to shared data in a webforJ environment. Both are accessible from anywhere in your app and serve different purposes:

📄️ Terminate and Error Actions

When developing applications with the webforJ, it's essential to define how your app behaves when it terminates or encounters an error. The framework provides mechanisms to customize these behaviors through terminate and error actions.

📄️ Asynchronous Updates

The Environment.runLater() API provides a mechanism for safely updating the UI from background threads in webforJ applications. This experimental feature enables asynchronous operations while maintaining thread safety for UI modifications.
