Introduction

A modern, Vue 3 compatible tree component library, built with TypeScript, for building dynamic, interactive tree structures on your web applications. vue-sapling-tree is a complete rewrite of the original vue-jstree for Vue 2, updated to take advantage of Vue 3's Composition API and TypeScript for better type checking and developer experience.

Features

Fully compatible with Vue 3 and TypeScript.
Supports dynamic tree construction from JSON data.
Customizable nodes with checkboxes, icons, and drag-and-drop.
Supports asynchronous data loading for large datasets.
Highly customizable through slots and CSS.
Events for node clicks, toggles, drag-and-drop actions.
Easy integration into Vue 3 projects with a modern, reactive API.
