Complete the Project Checklist

Use this checklist as the final sign-off for the project.

Board

• Three columns render correctly.
• Column counts match the visible tasks.
• Tasks render from React state.

Task actions

• Add Task opens the modal.
• Cancel and close hide the modal.
• New tasks appear in the selected column.
• Tasks can be deleted.
• Tasks can be dragged between columns.
• The target column visibly highlights during drag and drop.

Persistence

• Tasks are saved to localStorage.
• Saved tasks load after refresh.
• Create, delete, and move changes survive refresh.
• Invalid stored JSON does not crash the app.

Project quality

• No important errors appear in the browser console.
• The production build completes successfully.
• The code is understandable enough to explain to another developer.

Final checkpoint

If every box is checked, you have completed the React Kanban project. More importantly, you have practiced a complete React data flow: components render props and state, events trigger callbacks, state updates drive the UI, and browser storage preserves the result.
