Theme switchers enable users to customize application appearance with multiple color schemes, enhancing personalization and brand flexibility. As the creator of CoreUI, a widely used open-source UI library, I’ve built theme switchers for enterprise Vue applications throughout my 11 years of frontend development. The most versatile approach is managing theme state reactively and applying theme-specific CSS custom properties. This method supports unlimited themes, smooth transitions, and maintains persistent user preferences across sessions.

Dark mode improves user experience by reducing eye strain in low-light environments and has become an essential feature for modern web applications. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented dark mode in Vue applications throughout my 11 years of frontend development. The most effective approach is using Vue 3 Composition API with reactive state and CSS custom properties for theme switching. This method enables smooth theme transitions, persists user preferences, and maintains clean separation between logic and styling.

Responsive layouts adapt to different screen sizes and devices, providing optimal viewing experiences from mobile phones to desktop monitors. As the creator of CoreUI, a widely used open-source UI library, I’ve built responsive layouts in Vue applications throughout my 11 years of Vue development. The most effective approach is using CSS Grid and Flexbox with mobile-first media queries in Vue components. This method ensures layouts work across all devices while maintaining clean, maintainable code.

Sidebars provide persistent navigation for applications, offering quick access to main sections while maximizing content space in the main area. As the creator of CoreUI, a widely used open-source UI library, I’ve built sidebar navigation systems in Vue applications throughout my 11 years of Vue development. The most effective approach is creating a sidebar component with Composition API managing collapse state and responsive behavior. This method ensures consistent navigation with smooth transitions and mobile-friendly toggle functionality.

Navigation bars provide primary navigation structure for web applications, offering consistent access to main sections and improving user orientation across pages. As the creator of CoreUI, a widely used open-source UI library, I’ve built navigation systems in Vue applications throughout my 11 years of Vue development. The most effective approach is creating a navbar component with Vue Router integration and responsive mobile menu toggle. This method ensures seamless navigation with active route highlighting and mobile-friendly collapsible menus.

Dropdown components provide collapsible menus for navigation, actions, or selections, essential for space-efficient user interfaces and organized content. As the creator of CoreUI, a widely used open-source UI library, I’ve built dropdown systems in Vue applications throughout my 11 years of Vue development. The most maintainable approach is creating a reusable dropdown component with Composition API, managing open state and click-outside detection. This method ensures consistent dropdown behavior across applications with accessibility features and proper event handling.

Tooltips provide contextual information on hover without cluttering the interface, improving user experience with helpful hints and descriptions. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented tooltip systems in Vue applications throughout my 11 years of Vue development. The most maintainable approach is creating a reusable tooltip component with Composition API and conditional rendering on hover. This method ensures consistent tooltip behavior across the application with minimal code duplication.

Modal components provide overlay dialogs for user interactions without navigating away from the current page, essential for confirmations, forms, and focused content. As the creator of CoreUI, a widely used open-source UI library, I’ve built modal systems in Vue applications throughout my 11 years of Vue development. The most effective approach is using Vue 3’s Teleport component with Composition API to render modals at the document body level. This method prevents z-index conflicts and ensures modals display above all page content.

Managing cookies in Vue applications enables persistent data storage across browser tabs and sessions, essential for authentication tokens and user preferences. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented cookie-based state management in Vue applications throughout my 11 years of framework development. The most reliable approach is using the js-cookie library for simplified cookie operations with automatic encoding and expiration handling. This method provides cross-tab synchronization and server-side access to stored data.

Using sessionStorage in Vue applications maintains state during the browser session, perfect for temporary data like form drafts or wizard steps. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented sessionStorage integration in Vue applications throughout my 11 years of framework development. The most practical approach is combining Vue’s reactivity with sessionStorage using watchers for automatic synchronization. This method provides session-scoped persistence that clears when the browser tab closes.
