Step1: install plugins
npm install\
babel-plugin-syntax-jsx\
babel-plugin-transform-vue-jsx\
babel-helper-vue-jsx-merge-props\
babel-preset-env\
--save-dev
npm install vue-tree-halower --save
Step2： In your main.js
import 'vue-tree-halower/dist/halower-tree.min.css' // you can customize the style of the tree
import VTree from 'vue-tree-halower'
Vue.use(VTree)
Step3: In your .babelrc
{
"presets": ["env"],
"plugins": ["transform-vue-jsx"]
}
