typescript 2.9.x +webpack 4.16.x + react 16.4.x 从零开始,配置简单可自由更改,按需加载antd 3.8的组件,包括样式
前言:
由于网上找不到typescript结合react,并按需加载antd的教程,于是开始踩坑。
该过程中发现
1 “cannot resolve module ‘antd’” (tsconfig 中设置moduleResolution: “node”,告诉webpack去相应的node_modules目录下面寻找 antd,如果不这么做就得手动指定:
import Layout from ‘../../../node_modules/antd/lib/layout/index’;
一个个指定,但我就想要
import { Layout, Menu, Icon } from “antd”;
把组件和样式一起导入
) ;
2 无法解析 less (less 版本太高,降低版本即可,版本参考antd的package.json中使用的版本)
3 16.4.x版本的react缺少 prop-types 和 csstype( npm install -D prop-types @types/prop-types csstype )
(csstype 是css属性的集合,用typescript的角度来看,就是一堆接口的集合,可以用这些接口来做类型检查 )

此项目很简单,没有加入过多的功能,目前只提供 打包成一个文件、使用ts-import-plugin按需加载antd组件及其样式、热更新、解析less和css文件、url-loader图片,更多功能请自己添加。
1 安装依赖: npm install ; 推荐使用 cnpm install
