學習用TypeScript寫React組件

爲了折騰，簡單的學習了下TypeScript, 感受確實不錯。也爲了避免斷學習，避免落伍，因此就折騰不斷。css

前段時間用ES6，antd+dva寫了一些demo, 發現antd使用TypeScript實現的，並且angular2也採用了TypeScript。既然這麼多項目都提早使用了TypeScript, 而我又是React的粉，那麼仍是先研究下TypeScript實現React組件。html

鑑於剛開始，仍是站在別人的肩膀上開始吧。node

工具選擇

本人對webpack配置略知一二，但暫時還不想太深刻到工程方面的研究，因此，工具選擇開源的，有阿里使用的atool-build, roadhog. 嘗試屢次，鑑於以前的項目都是用的roadhog, 並且也看了roadhog git上面已經說支持TypeScript, 因此最終選擇了roadhog, 由於它配置確實簡單、省心。react

不過要使用roadhog的0.6.0-beta2版本(由於以前的版本不支持TypeScript)：webpack

npm install roadhog@0.6.0-beta2 --save-dev

配置文件:git

//.roadhogrc
{
  "entry": "src/index.js",
  "publicPath": "/dist/",
  "outputPath": "./dist",
  "env": {
    "development": {
      "extraBabelPlugins": [
        "dva-hmr",
        "transform-runtime"
      ]
    },
    "production": {
      "extraBabelPlugins": [
        "transform-runtime",
        ["import", { "libraryName": "antd", "style": "css" }] // 加入這一條，import antd的樣式的時候纔不會被md5
      ]
    }
  }
}

項目結構

+------- src
         +----- components
         +----- models
         +----- routes
+------- .roadhog
+------- node_modules
+------- package.json
+------- ...

項目結構基本和antd-admin的結構保持一致。github

入口文件

// index.js
import './index.html'
import 'babel-polyfill'
import dva, { connect } from 'dva'
import createLoading from 'dva-loading'
import { browserHistory, Router, Route } from 'dva/router'

/**
 * @desc 如下是解決域名下面子目錄部署問題
 * 域名項目下面通常會有多個子項目，那麼部署的時候，子目錄的做用就相當重要了。
 * 不借助basename不太容易實現。
 */
import { useRouterHistory } from 'dva/router'
import createBrowserHistory from 'history/lib/createBrowserHistory'

const history = useRouterHistory(createBrowserHistory)({basename: '/mda'})

// 1. Initialize
const app = dva({
  ...createLoading(),
//  history: browserHistory,
  history,
  onError (error) {
    console.error('app onError -- ', error)
  },
})

// 2. Model
app.model(require('./models/app'))


// 3. Router
app.router(require('./router'))

// 4. Start
app.start('#root')

應用模塊(src/routes/app.js)

import React from 'react'
import PropTypes from 'prop-types'
import { connect } from 'dva'


import {
  Icon,
  Row,
  Col,
  Button,
  Modal,
} from '../components'
import 'antd/dist/antd.css'
import styles from './app.less'

function App ({ children, location, dispatch, app, loading }) {
  const {
    isVisible,
  } = app

  const showModal = () => {
    dispatch({
      type: 'app/showModal',
    })
  }

  const handleOk = () => {
  }

  const handleCancel = () => {
    dispatch({
      type: 'app/hideModal',
    })
  }
  return (
    <div className={styles.normal}>
      <Row>This is a row</Row>
      <Row>
        <Col span={12}>這是一個Col</Col>
        <Col span={12}>這是一個Col</Col>
      </Row>
      <Button type="primary" onClick={showModal}><Icon type="link" />彈窗</Button>
      <Modal title="彈窗標題" visible={isVisible} onOk={handleOk} onCancel={handleCancel}>
        <div>Hello</div>
      </Modal>
    </div>
  )
}

App.propTypes = {
  children: PropTypes.element.isRequired,
  location: PropTypes.object,
  dispatch: PropTypes.func,
  app: PropTypes.object,
  loading: PropTypes.bool,
}

export default connect(({ app, loading }) => ({ app, loading: loading.models.app }))(App)

組件

組件位於src/components, 開始學習的時候，能夠直接從ant-design源代碼的components中拷貝代碼過來，對於簡單的組件Button, Grid, Icon, 能夠拷貝過來，而後直接跑起來，不過注意安裝必要的包。web

基本依賴包
