## Introduction

### CRUD

el-data-tree is created to solve business problems, so CRUD logic is set inside.<br /> For example, to develop `user` api, suppose its relative path like this:

```sh
/api/v1/users
```

The restful CRUD api should be:

- Retrieve

```javascript
GET /api/v1/users?type=1
```

- Create

```javascript
POST / api / v1 / users
```

- Update

```javascript
PUT /api/v1/users/:id
```

- Delete

```javascript
DELETE /api/v1/users/:id
```

Then only need to use the following code to complete CRUD functions

```html
<template>
  <el-data-tree v-bind="treeConfig"></el-data-tree>
</template>
```

```javascript
<script>
export default {
  data() {
    return {
      treeConfig: {
        url: '/example/users',
        dataPath: 'data.payload',
        showFilter: true,
        form: [
          {
            $type: 'input',
            $id: 'name',
            label: '用户名',
            $el: {
              placeholder: '请输入'
            },
            rules: [
              {
                required: true,
                message: '请输入用户名',
                trigger: 'blur'
              }
            ]
          }
        ]
      }
    }
  }
}
</script>
```

The results are as follows：

- Retrieve

- Create

## Quick Start

### Global Register Component

This is for minification reason: in this way building your app, webpack or other bundler just bundle the dependencies into one vendor for all pages which using this component, instead of one vendor for one page

```javascript
import Vue from 'vue'
// register component and loading directive
import ElDataTree from '@femessage/el-data-tree'
import ElFormRenderer from '@femessage/el-form-renderer'
import {
  Button,
  Dialog,
  Dropdown,
  DropdownMenu,
  DropdownItem,
  Form,
  FormItem,
  Input,
  Loading,
  Tree,
  MessageBox,
  Message
} from 'element-ui'
Vue.use(Button)
Vue.use(Dialog)
Vue.use(Dropdown)
Vue.use(DropdownMenu)
Vue.use(DropdownItem)
Vue.use(Form)
Vue.use(FormItem)
Vue.use(Input)
Vue.use(Loading.directive)
Vue.use(Tree)
Vue.component('el-form-renderer', ElFormRenderer)
Vue.component('el-data-tree', ElDataTree)
// to show confirm before delete
Vue.prototype.$confirm = MessageBox.confirm
// if the tree component cannot access `this.$axios`, it cannot send request
import axios from 'axios'
Vue.prototype.$axios = axios
```
