使用typescript开发react应用
初始化
mkdir project-dir
cd project-dir
yarn init -y
安装依赖
yarn add react react-dom
yarn add -D typescript @types/react @types/react-dom
配置tsconfig.json
npx tsc --init
将 compilerOptions 下的 jsx 项配置成 react
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"jsx": "react",
"strict": true,
"esModuleInterop": true
}
}
配置webpack文件
yarn add -D webpack webpack-cli html-webpack-plugin webpack-merge webpack-dev-server
yarn add -D awesome-typescript-loader source-map-loader
webpack.common.js
// webpack/webpack.common.js
const path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');
const htmlTemplate = new HtmlWebpackPlugin({
template: path.resolve(__dirname, '../index.html'),
})
const config = {
entry: path.resolve(__dirname, '../src/index.tsx'),
output: {
path: path.resolve(__dirname, '../src', 'dist')
},
resolve: {
extensions: [".ts", ".tsx", ".js", ".json"]
},
module: {
rules: [
{ test: /\.tsx?$/, loader: "awesome-typescript-loader" },
{ enforce: "pre", test: /\.js$/, loader: "source-map-loader" }
]
},
plugins: [
htmlTemplate,
]
}
module.exports = config;

webpack.dev.js
// webpack/webpack.dev.js
const path = require('path');
const merge = require('webpack-merge');
const common = require('./webpack.common');
module.exports = merge(common, {
mode: 'development',
devtool: 'inline-source-map',
devServer: {
contentBase: path.join(__dirname, "../dist"),
compress: true,
port: 9000,
open: true,
}
})
开始玩吧
// src/index.tsx
import React from 'react';
import ReactDOM from 'react-dom';
import Hello from './hello';
ReactDOM.render(<Hello name={'Typescript'} />, document.getElementById('app'));
// src/hello.tsx
import React, { PureComponent } from 'react';
interface HelloProps {
name: string;
}
export default class Hello extends PureComponent {
constructor(public props: HelloProps) {
super(props);
}
render() {
const { name } = this.props;
return (
<h1>Hello {name}</h1>
);
}
}
