1.拉取一份 react创建的工程 地址
2. 开发 思路
- 分两个文件夹
- dev 开启一个react开发项目
- src 为具体库的实现代码
- 然webpack配置一个正常的react项目，入口设置为dev下面的index
- 这样启动这个webpack，就可以在线开发src下面的库了
2.1 以实现一个react弹窗组件为例，先写一个弹窗组件
// src\index.tsx
import React, { Component } from 'react';
import { createPortal } from 'react-dom';
import './index.scss';
export interface IDialogProps{
hideDialog:Function
}
export default class Dialog extends Component<IDialogProps> {
node:HTMLElement;
constructor(props:IDialogProps) {
super(props);
this.node = document.createElement('div');
this.node.classList.add('dialog');
}
componentDidMount() {
document.body.appendChild(this.node);
}
componentWillUnmount() {
document.body.removeChild(this.node);
}
render() {
const { hideDialog, children } = this.props;
return createPortal(
<div className="dialog-model">
{children}
{typeof hideDialog === 'function' && (
<button onClick={() => hideDialog()} type="button">关闭窗口</button>
)}
</div>, this.node,
);
}
}2.2 在example开启react开发项目，并且使用src导出的Dialog
// example\index.tsx
import React, { useState } from 'react'
import ReactDOM from 'react-dom';
import Diallog from '../src/index'
function App(){
const [isShowDialog,setIsShowDialog] = useState(false)
return (
<div>
<h3>DialogPage</h3>
<button onClick={() => setIsShowDialog(true)}>
toggle
</button>
{isShowDialog && <Diallog children="hello" hideDialog={() => setIsShowDialog(false)} />}
</div>
)
}
ReactDOM.render(<App />,document.getElementById('root'));2.3 配置 example 的webpack
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
entry: './dev/index.tsx',
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'build'),
},
mode: 'development',
devtool: 'inline-source-map',
devServer: {
contentBase: './build',
// 启动gzip 压缩0
compress: true,
// 端口号
port: 8080,
open: true,
hot: true,
},
plugins: [
new HtmlWebpackPlugin({ template: './index.html' }),
],
module: {
rules: [
{
test: /\.html$/i,
// 处理html文件的img图片(负责引入img,从而能被url-loader进行处理)
loader: 'html-loader',
},
{
test: /\.(ts|js)x?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.(png|svg|jpg|jpeg|gif)$/i,
type: 'asset/resource',
generator: {
filename: 'static/images/[hash][ext][query]',
},
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/i,
type: 'asset/resource',
generator: {
filename: 'static/font/[hash][ext][query]',
},
},
{
test: /\.((c|sa|sc)ss)$/i,
use: [
"style-loader",
"css-loader",
'sass-loader'
]
}
]
},
optimization: {
splitChunks: {
chunks: 'all',
},
},
resolve: {
// 配置省略文件路径的后缀名
extensions: ['.tsx', '.ts', '.js'],
},
}2.4 最后 npm run start 就可以愉快的开发自己的库了
3.打包思路
- 开启一个
webpack,配置为library - 排除用到的
react - 去掉corejs
3.1 配置一个生产环境的webpack
const MiniCssExtractPlugin = require("mini-css-extract-plugin")
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const path = require('path');
module.exports = {
entry: './src/index.tsx',
mode: 'production',
devtool: 'source-map',
output: {
filename: 'index.js',
path: path.resolve(__dirname, 'dist'),
library:'react-dialog',
libraryTarget: 'umd'
},
plugins: [
new CleanWebpackPlugin(),
new MiniCssExtractPlugin({
filename: 'style.css',
chunkFilename: '[id].css',
}),
],
module: {
rules: [
{
test: /\.(ts|js)x?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.(png|svg|jpg|jpeg|gif)$/i,
type: 'asset/resource',
generator: {
filename: 'static/images/[hash][ext][query]',
},
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/i,
type: 'asset/resource',
generator: {
filename: 'static/font/[hash][ext][query]',
},
},
{
test: /\.((c|sa|sc)ss)$/i,
use: [
{
loader: MiniCssExtractPlugin.loader,
},
// 将css文件变成commonjs模块加载js中，里面内容是样式字符串
{
loader: 'css-loader',
options: {
importLoaders: 2,
}
},
'postcss-loader',
'sass-loader'
],
},
]
},
resolve: {
// 配置省略文件路径的后缀名
extensions: ['.tsx', '.ts', '.js'],
},
externals:{
react:'react',
'react-dom':'react-dom'
}
}library:'react-dialog'是库名称,libraryTarget: 'umd'编译库的目标,umd 代表ES2015,CommonJS可以使用externals,用户会导入的库，这里不用引入，减少打包体积
3.2 去掉corejs,这里不引入减少打包体积，放给用户去引入
// .babelrc
{
"presets": [
"@babel/env",
"@babel/preset-react",
"@babel/preset-typescript"
],
"plugins": [
"@babel/plugin-proposal-class-properties"
]
}3.3 运行npm run build，会打包我们的组件库
4. 推送到npm
4.1 修改package.json
"name": "@shen9401/react-dialog",
"main": "dist/index.js",
"module": "dist/index.js",
"style": "dist/style.css",
"files": [
"dist"
],mainnode和浏览器所需要的文件 ;module是node和浏览器ES模块需要的文件"sideEffects": false,会忽略css
4.2 登录到自己的npm账户
npm adduser --registry=https://registry.npmjs.org/- 会提示输入用户名，密码，邮箱，以及注册邮箱的验证码
4.3 使用 nrm use npm 切换到npm 源
4.4 npm publish --access public 发布公共包
5.新建一个react项目
5.1 执行 npm i @shen9401/react-dialog 按照包
5.2 引入并使用
import Diallog from '@shen9401/react-dialog'
import '@shen9401/react-dialog/dist/style.css'
function App() {
const [isShowDialog,setIsShowDialog] = useState(false)
return (
<div className="App">
<button onClick={() => setIsShowDialog(true)}>
toggle
</button>
{isShowDialog && <Diallog children="hello" hideDialog={() => setIsShowDialog(false)} />}
</div>
);
}6. 合并js和css, 修改webpack 配置，避免引入组件之后还要引入样式
{
test: /\.((c|sa|sc)ss)$/i,
use: [
"style-loader",
// 将css文件变成commonjs模块加载js中，里面内容是样式字符串
{
loader: 'css-loader',
options: {
importLoaders: 2,
}
},
'postcss-loader',
'sass-loader'
],
},- 去掉
MiniCssExtractPlugin,改用style-loader
