基于config-component转向面向数据的编程?
面向数据编程
面向数据编程是什么样的体验?
其实是数据驱动式编程更向前走一步,我们知道现在MVVM框架,像React、vue、Angular这些给前端带来了很大的进步,更优雅的工程化体系结构,更健壮的代码体系结构。同样给开发者带来了数据驱动式开发的体验,但是业务代码还是经常会出现业务逻辑与UI表达形式的穿插混合的情况,很难统一。

样式行为分离
面向数据的编程其实核心思想还是做样式行为分离,中间的解耦利器便是数据。
样式 mix 行为 = 样式 + 数据 + 行为
于是我们抽象出来的config-component组件,作为驱动样式行为分离的通用组件,驱动面向数据编程。
例如实现下面的表单:
基于antd组件库,比较下不同的代码结构:
左边的图是基于ANTD正常的写法,我们要写Form,要写检验规则,要写子组件等等,关键是这些逻辑是糅合在一起的。右边是基于config-component提供的ConfigForm组件做了封装,只需要提供JSON schema配置数据即可驱动你的页面,分离数据校验和UI逻辑,UI逻辑基于UIconfig,数据校验基于schema做校验。
creative feature创新特性
✅ change your code style to face data, use JSON schema config to driven you page.数据驱动式开发更进一步转向面向数据编程,结合React Hooks开发更高效,专注于数据和业务逻辑.基于JSON配置数据驱动你的页面或者表单。
✅ add schema mechanism to ensure you data correct and force you to care you data and handle the abnormal situation.开发中引入schema机制验证核心数据的正确性,无论是表单还是前台组件均可适用。
✅ support get data async, verify data when it changes.基于schema动态校验数据,支持异步数据更新,响应式做校验。
usage用法
安装:
npm install config-component --save
config-component默认提供了2中类型组件,
- ConfigComponent, 通用类型组件,配置页面逻辑,用于前台页面
- ConfigForm, 专用于配置化表单,可以用中后台页面
For common component:
import {ConfigComponent} from 'config-component' ... <ConfigComponent initialValues={...} schema={...} uiConfig={...} />
For form component:
import {ConfigForm} from 'config-component' ... <ConfigComponent initialValues={...} schema={...} uiConfig={...} onSubmit={()=>{...}} componentSet={...} />
params:
ℹ️schema: the core data you care, ConfigComponent will verify you core data with schema,you can specify alt props in item, when error occurs, will show alt as default value
ℹ️initialValues: init value in you comp
ℹ️uiConfig: define your ui interface with json config, support event hooks, see example in playground file.
ℹ️onSubmit: used only in form when submit data.
ℹ️componentSet: support Ant Design or Fusion or you selfdefine Components.
代码示例:
import React, { useContext } from 'react' import * as yup from 'yup' import * as AntdComponents from 'antd' import moment from 'moment' import { ConfigForm } from 'config-component' import 'antd/dist/antd.css' const schema = yup.object().shape({ firstName: yup.string().required(), lastName: yup.string().required(), startTime: yup.array().required(), useTime: yup.array().required().when('startTime', (startTime, schem) => { return schem.test( 'check-start', 'useTime required', value => { return !!value }, ).test( 'check-start', 'useTime start >= startTime start', value => { return value && startTime[0].milliseconds(0).valueOf() <= value[0].milliseconds(0).valueOf() }, ).test( 'check-end', 'useTime end >= startTime end', value => { return value && startTime[1].milliseconds(0).valueOf() <= value[1].milliseconds(0).valueOf() }, ).required() }), agree: yup.boolean().required().test( 'check-agree', 'agree must checked', value => { return !!value }, ).required(), }) const initialValues = { firstName: 'Tony', lastName: 'Stark', startTime: [moment('2019-09-01'), moment('2019-09-03')], } export default function App() { const formConfig = { initialValues, schema, onSubmit: values => console.log('Your values are:', values), componentSet: AntdComponents, } const formItemLayout = { labelCol: { xs: { span: 24 }, sm: { span: 8 }, }, wrapperCol: { xs: { span: 24 }, sm: { span: 16 }, }, } const tailFormItemLayout = { wrapperCol: { xs: { span: 24, offset: 0, }, sm: { span: 16, offset: 8, }, }, } const onChangeWrapper = schemaKey => (form, e) => { const { onChange, value } = form.getFieldProps(schemaKey) console.log('prevalue', value) onChange(e) } return ( <ConfigForm {...formConfig} uiConfig={{ layout: formItemLayout, items: [ { label: 'First Name: ', comp: 'Input', schemaKey: 'firstName', props: {}, }, { label: 'Last Name: ', comp: 'Input', schemaKey: 'lastName', props: { onChange: onChangeWrapper('lastName'), }, }, { label: 'Start Time: ', comp: 'DatePicker.RangePicker', schemaKey: 'startTime', props: {}, }, { label: 'Use Time: ', comp: 'DatePicker.RangePicker', schemaKey: 'useTime', props: {}, }, { layout: tailFormItemLayout, comp: [ { comp: 'Checkbox', schemaKey: 'agree', props: { color: '#999', }, }, { comp: 'span', children: '同意协议', props: { style: { marginLeft: '10px', color: '#999', }, }, }, ], props: {}, }, { type: 'submit', layout: tailFormItemLayout, comp: [ { type: 'submit', comp: 'Button', children: '提交', props: { type: 'primary', htmlType: 'submit', key: 'submit', }, }, { type: 'reset', comp: 'Button', children: '重置', props: { type: 'primary', key: 'reset', style: { marginLeft: '10px' }, }, }, ], props: {}, }, ], }} /> ) }
