篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了react组件化开发发布到npm相关的知识,希望对你有一定的参考价值。

1.项目目录

  • build:webpack打包用(开发环境、发布环境)
  • example:开发环境的模板页
  • lib:打包好的文件夹(用于发布到npm上)
  • src:想要封装的公共组件
  • .babelrc:处理es6语法
  • package.json:打包的依赖文件,管理项目模块包

开发环境配置(webpack.dev.config.js)

const path = require(‘path‘)
const htmlWebpackPlugin = require(‘html-webpack-plugin‘)

module.exports = {
  entry: path.join(__dirname, ‘../example/main.js‘),
  devtool: ‘cheap-module-eval-source-map‘,
  output: {
    path: path.join(__dirname, ‘../dist‘),
    filename: ‘bundle.js‘
  },
  plugins: [ // 插件
    new htmlWebpackPlugin({
      template: path.join(__dirname, ‘../example/index.html‘),
      filename: ‘index.html‘
    })
  ],
  module: {
    rules: [
      { test: /.css$/, use: [‘style-loader‘, ‘css-loader‘] }, // 如果想要启用 CSS 模块化,可以为 css-loader 添加 modules 参数即可
      { test: /.scss$/, use: [‘style-loader‘, ‘css-loader‘, ‘sass-loader‘] },
      { test: /.(jpg|png|gif|bmp|jpeg)$/, use: ‘url-loader?limit=5000‘ },
      { test: /.(ttf|eot|svg|woff|woff2)$/, use: ‘url-loader?limit=5000‘ },
      { test: /.jsx?$/, use: ‘babel-loader‘, exclude: /node_modules/ }
    ]
  }
}

打包环境配置(webpack.pub.config.js)

const path = require(‘path‘)
// 导入每次删除文件夹的插件
const cleanWebpackPlugin = require(‘clean-webpack-plugin‘)
const webpack = require(‘webpack‘)
// 导入抽取CSS的插件
const ExtractTextPlugin = require("extract-text-webpack-plugin")
// 导入压缩CSS的插件
const OptimizeCssAssetsPlugin = require(‘optimize-css-assets-webpack-plugin‘)

module.exports = {
  entry:  path.join(__dirname, ‘../src/index.js‘),
  devtool: ‘cheap-module-source-map‘,
  output: {
    path: path.join(__dirname, ‘../lib‘),
    filename: ‘index.js‘,
    libraryTarget: ‘umd‘,  //发布组件专用
    library: ‘ReactCmp‘,
  },
  plugins: [ // 插件
    new cleanWebpackPlugin([‘./lib‘]),
    new webpack.optimize.UglifyJsPlugin({
      compress: { // 配置压缩选项
        warnings: false // 移除警告
      }
    }),
    new ExtractTextPlugin("css/styles.css"), // 抽取CSS文件
    new OptimizeCssAssetsPlugin()// 压缩CSS的插件
  ],
  module: {
    rules: [
      {
        test: /.css$/, use: ExtractTextPlugin.extract({
          fallback: "style-loader",
          use: "css-loader",
          publicPath: ‘../‘ // 指定抽取的时候,自动为我们的路径加上 ../ 前缀
        })
      },
      {
        test: /.scss$/, use: ExtractTextPlugin.extract({
          fallback: ‘style-loader‘,
          use: [‘css-loader‘, ‘sass-loader‘],
          publicPath: ‘../‘ // 指定抽取的时候,自动为我们的路径加上 ../ 前缀
        })
      },
      { test: /.(jpg|png|gif|bmp|jpeg)$/, use: ‘url-loader?limit=5000&name=images/[hash:8]-[name].[ext]‘ },
      { test: /.(ttf|eot|svg|woff|woff2)$/, use: ‘url-loader?limit=5000&name=images/[hash:8]-[name].[ext]‘ },
      { test: /.js$/, use: ‘babel-loader‘, exclude: /node_modules/ }
    ]
  }
}

组件

// button.js 封装的button组件
import React, { Component } from ‘react‘;
import PropTypes from ‘prop-types‘;
export default class Button extends Component {
  constructor(props) {
    super(props)
  }
  static propTypes = {
    /**
     * @title 样式定义
     * @description 通过CSS定义按钮的样式
     */
    style: PropTypes.shape({
      color: PropTypes.string,
      fontSize: PropTypes.number,
      background: PropTypes.string,
      padding: PropTypes.string,
    }),
  };

  static defaultProps = {
    style: {
      color: ‘#fff‘,
      background: ‘green‘,
      padding: ‘4px‘,
    },
  };
  render() {
    const style = this.props.style;
    return (
      <button style={style}>{this.props.children}</button>
    );
  }
}

// index.js输出文件
import React from ‘react‘;
import RCmp from ‘./app‘;
import Button from ‘./button‘;
import Photo from ‘./photo‘;
import ‘./app.scss‘;
RCmp.Button = Button;
RCmp.Photo = Photo;
export default RCmp;
export {
  Button,
  Photo,
  RCmp,
}

实时调试

npm run dev

发布

npm run pub

将lib导入到node_modules

引入

iimport React from ‘react‘;
import PropTypes from ‘prop-types‘;
import {
  modal
} from ‘math_manage‘
import AutoSuggest from ‘react-tiny-autosuggest‘;
import MyApp,{Button,Photo,} from ‘react-cmp-master‘;

class App extends React.Component {
  static defaultProps = {}
  static propTypes = {}

  constructor(props) {
    super(props);
  }
  componentWillMount() {
    document.title = "1666";
    console.log(modal);
  }
  render() {
    const suggestions = [‘foo‘, ‘bar‘];  
    const handleSelect = selection => {console.log(selection)};

    let input;
    const handleSubmit = () => console.log(input.value);
    return (
      <div> 
        <AutoSuggest
          suggestions = {suggestions}
          onSelect = {handleSelect}
          placeholder = "whatever..." 
        />
        <MyApp text=‘Hello react组件‘/>
        <Button/>
        <Photo src={‘https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2198746125,2255961738&fm=27&gp=0.jpg‘}/>
      </div>
    )
  }
}

export default App;
