环境搭建
2.引入Typescript
- 安装依赖
npm i -S @types/react @types/react-dom
npm i -D typescript awesome-typescript-loader source-map-loader
- 新建tsconfig.json
{
"compilerOptions": {
"outDir": "./dist/","sourceMap": true,"noImplicitAny": true,"module": "commonjs","target": "es5","jsx": "react"
},"include": [
"./src/**/*"
]
}
- 修改webpack.config.js
// webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
module.exports = {
entry: {
index:'./src/index.js',},output: {
filename: 'bundle.js',path: path.resolve(__dirname,'dist')
},devtool: "source-map",// Add '.ts' and '.tsx' as resolvable extensions.
resolve: {
extensions: ['.ts','.tsx','.js','.jsx']
},module: {
rules: [
{
test: /\.css$/,use: ['style-loader','css-loader']
},{
test: /\.(png|svg|jpg|gif)$/,use: ['url-loader']
},{
test: /\.(woff|woff2|eot|ttf|otf)$/,{
test: /\.(js|jsx)$/,exclude: /node_modules/,use: {
loader: 'babel-loader'
}
},// All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
{
test: /\.tsx?$/,loader: "awesome-typescript-loader"
},]
},plugins: [
new HtmlWebpackPlugin({
title: 'production',template: './index.html'
}),new webpack.NamedModulesPlugin(),new webpack.HotModuleReplacementPlugin()
],devServer: {
contentBase: './dist',hot: true
},};
3.引入less并支持import less modules
- 安装依赖
npm i -D less less-loader
npm i -D typings-for-css-modules-loader
tips: typings-for-css-modules-loader
打包时将样式模块化，我们可以通过import或require引入样式，并且相互不冲突。
//demo.less -> demo.less.d.ts
//.demo{color:red;} -> export const demo: string;
import * as styles from 'demo.less'
<DemoComponent className={styles.demo} />
- 修改webpack.config.js
// webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
module.exports = {
entry: {
index:'./src/index.js',//add .less
resolve: {
extensions: ['.ts','.jsx','.less','.css']
},//import less modules，name：demo__demo___hash
{
test: /\.less/,use: [
'style-loader','typings-for-css-modules-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]&namedExport&camelCase&less!less-loader'
]
},{
test: /\.tsx?$/,};
4.引入react-routerv4
npm i -S react-router-dom
- 创建history
import { createHashHistory } from 'history';
export default createHashHistory();
- 使用
import React from 'react';
import ReactDom from 'react-dom';
import * as styles from "./index.less";
import history from './helpers/history';
import {Router,Route,Switch,Redirect,Link} from 'react-router-dom';
import Hello from "./router/Hello";
import TodoList from "./router/TodoList";
const PrivateRoute = ({ component: Component,...rest}) => {
return (
<Route {...rest} render={props => (
<Component {...props}/>
)}/>
);
}
ReactDom.render(
<Router history={history} >
<div className={styles.wrap}>
<ul>
<li><Link to="/">Homes</Link></li>
<li><Link to="/todo">TodoList</Link></li>
</ul>
<Switch>
<Route exact path="/" component={Hello}/>
{/*<Route path="/demo" component={Demo}/>*/}
<PrivateRoute path="/todo" component={TodoList} />
</Switch>
</div>
</Router>,document.getElementById('root')
);
-
...ES7语法报错
npm i -S babel-preset-stage-2
修改.babelrc
{
"presets": ["es2015","react","stage-2"],}
5.引入mobx状态管理
npm i -S mobx mobx-react
- 使用装饰器语法
修改tsconfig.json
"compilerOptions": {
"target":"es2017",//fix mobx.d.ts error
"experimentalDecorators": true,"allowJs": true
}
npm i -D babel-plugin-transform-decorators-legacy
修改.babelrc
{
"presets": ["es2015","plugins": ["transform-decorators-legacy"]
}
