We’re excited to announce the release of CoreUI Free React.js Admin Template v5.6.0 on March 30, 2026! This update focuses on critical bug fixes, performance improvements, and enhanced developer experience with memory leak fixes and Fast Refresh support.

We are excited to announce the release of CoreUI PRO React Admin Template v5.9.0 on March 30, 2026! This update brings JSX file extension refactoring, critical memory leak fixes, comprehensive dependency updates, and improved code organization to deliver a more maintainable and performant enterprise admin template.

We are pleased to announce the release of CoreUI PRO for React v5.24.1. This maintenance release includes bug fixes and improvements while maintaining all functionality from v5.24.0, including the powerful Calendar component with custom cell rendering and quarter selection, plus Chip and Chip Input components.

Memory leaks in React occur when components are unmounted but still hold references to timers, subscriptions, or callbacks. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve debugged memory leaks that caused applications to slow down and eventually crash after extended use. The primary fix is returning cleanup functions from useEffect to cancel ongoing operations before the component unmounts. This prevents the classic “Can’t perform a React state update on an unmounted component” warning.

A Kanban board organizes tasks into columns representing workflow stages, with drag-and-drop for moving cards between them. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built Kanban-style interfaces for project management tools, sprint planners, and support ticket systems. The most effective approach stores board state as a map of column IDs to card arrays, uses HTML5 drag-and-drop for movement, and rerenders on every drop. This provides a functional board without heavy dependencies.

Building a calendar component requires generating grids of days, handling month navigation, and marking events on specific dates. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built calendar interfaces for booking systems, scheduling tools, and project management dashboards. The most effective approach calculates the days grid from the current month state, renders weeks as rows, and highlights today and event dates. This produces a functional calendar with pure React and no external date libraries.

A notes application is an ideal project for mastering React state management, CRUD operations, and data persistence. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built note-taking interfaces for knowledge management tools, CMS editors, and productivity dashboards. The most effective approach uses useState for notes, useEffect for localStorage persistence, and controlled inputs for editing. This delivers a fully functional notes app with minimal complexity.

Building a todo application is a classic way to learn React fundamentals including state management, event handling, and component composition. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built todo-style interfaces for task management systems, project tracking tools, and checklist applications. The most effective approach uses useState for managing todos, useEffect for persistence, and controlled inputs for adding new items. This provides a fully functional todo app with all essential features.

Building a chat application requires managing message lists, user input, real-time updates, and smooth scrolling behavior. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built chat interfaces for applications ranging from simple customer support to complex team collaboration platforms. The most effective approach uses useState for messages, useRef for scroll management, and controlled inputs for message composition. This pattern provides a responsive, user-friendly chat experience.

Building a settings page is essential for applications that allow users to customize their experience and manage preferences. As the creator of CoreUI with over 10 years of React experience since 2014, I’ve built settings interfaces for applications ranging from simple user preferences to complex enterprise configuration panels. The most effective approach organizes settings into logical sections, uses controlled components for all inputs, and persists changes to localStorage or an API. This pattern provides a professional, user-friendly settings interface.
