Developer Builds Drag-and-Drop Kanban Board Using Only Vanilla JavaScript

A developer shared a tutorial on DEV Community detailing how to build a fully functional Kanban board using plain HTML, CSS, and JavaScript, without any libraries or frameworks. The project features three columns — To Do, In Progress, and Done — with draggable cards that can be moved between them using the browser's native HTML5 Drag and Drop API. Key implementation details include storing a card's ID in the dataTransfer object on drag start and using appendChild() to relocate the card node upon drop. A common pitfall highlighted is the need to call preventDefault() inside the dragover event handler, as browsers block dropping by default without it. The developer noted that persistence via localStorage, card editing, and mobile touch support are potential next steps, and has published the source code on GitHub.
