Vue 3.x Form render

github: vue form render

在线演示

为什么要造这个轮子?

之前用过 React 的 Form Render 的小伙伴应该比较清楚 Form Render 可以基于 JSON Schema 快速构建出表单区块。不得不说 For Render 在以下场景中的使用会给开发带来巨大的便利:

  1. 规范化表单视图的快速生成:写好对应的参数配置,快速生成一个标准表单,省去了使用类 Ant Design 表单的麻烦地方
  2. 可视化配置界面生成:并可以从代码层面 自动生成 JSON Schema,来完成整体流程的打通
  3. 服务能力配置界面生成:常用于后台字段系统中,接口同学通过吐 JSON Schema 字段给前端界面,渲染出他所想要的界面以及获取用户的输入进行提交给后端,可以起到无需发布就可无缝扩展各种类型的作用
  4. 作为配置输入和搭建系统配合使用:FormRender 在正常展示的情况下,可以很简单的进行和原主题的适配使用

但是现在我们的场景是基于 vue 3.x 的框架基础上去使用 form render 但是 form render 目前也只支持 react。然后我再 Google 上搜了一大圈,也没找到一个还可以的 vue 3.xform render,不过 vue 2.x 的还是挺多的。出于这样的诉求,自己动手撸了一个。

功能

vue-form-render 是基于 Form Render 基本能力作为原型实现的 Vue 3.x 版本的表单渲染器,目前支持 90% 左右的 Form Render 功能,后续会不断的维护支持。

快速使用

依赖ant-design-vue

import { createApp } from 'vue'
import App from './App.vue'

import Antd from 'ant-design-vue';
import 'ant-design-vue/dist/antd.css';

const app = createApp(App);
app.use(Antd);
app.mount('#app');

引入vue-form-render

npm i kaer-form-render --save
<template>
  <div>
    <formRender
      :schema="schema"
      :formData="formData"
      @on-change="change"
      @on-validate="validate"
    />
  </div>
</template>

<script>
import {reactive, toRefs} from 'vue';

// render index
import FormRender from 'kaer-form-render';
// form render style
import 'kaer-form-render/lib/kaer-form-render.css';

export default {
  name: 'App',
  setup() {
    const state = reactive({
      schema: {
        type: 'object',
        properties: {
          string: {
            title: 'string',
            type: 'string',
            maxLength: 4,
            'ui:options': {
              placeholder: 'enter more than 4 characters',
            },
          }
        },
      },
      formData: {
        string: 'aaa'
      },
    });

    const change = (v) => {
      state.formData = v;
      console.log(v);
    }
    const validate = (v) => {
      console.log(v);
    }

    return {
      ...toRefs(state),
      change,
      validate,
    }
  },
  components: {
    FormRender,
  }
}
</script>
