Webpack4+React16+ReactRouter4+Redux整合开发 - Redux Logger日志相关配置

之前的几篇文章继承了redux，这里不得不说下与redux开发相关的一些配置redux-logger，其实有很多，也有另外一种方式，这里我觉得这个是比较好的，这里做下记录，跟大家分享下。

首先clone代码

git clone https://github.com/durban89/webpack4-react16-reactrouter-demo.git redux-devtools
cd redux-devtools
npm install 

npm start

然后安装redux-logger

npm install redux-logger

打开src/index.jsx
引入redux-logger

import { createLogger } from 'redux-logger';

更新修改代码结果如下

const middleware = [];
if (typeof __DEV__ !== 'undefined') {
  middleware.push(createLogger()); // 创建日志
}
// 为了添加多个中间件 我们重新改造middleware
middleware.push(routerMiddleware(history));

// 这行是DevTools的配置 后面做详细说明
const composeEnhancer = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(
  connectRouter(history)(rootReducer),
  initialState,
  composeEnhancer(applyMiddleware(...middleware)), // 中间件引入
);

日志一般是在开发环境中使用，我们需要加个变量来做下控制，这里通过修改webpack.config.js中的plugins加入

new webpack.DefinePlugin({
  'global.GENTLY': false,
  __DEV__: true,
})

配置完结果如下

const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');

let config = {
  entry: {
    app: [
      'webpack/hot/only-dev-server',
      'react-hot-loader/patch',
      './src/index.jsx',
    ],
  },
  plugins: [
    new CleanWebpackPlugin(['dist']),
    new HtmlWebpackPlugin({
      title: 'React + ReactRouter Demo',
      filename: './index.html', // 调用的文件
      template: './index.html', // 模板文件
    }),
  ],
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
    rules: [{
      test: /\.(js|jsx)$/,
      loader: 'babel-loader',
      exclude: [
        path.resolve(__dirname, 'node_modules'),
      ],
      options: {
        plugins: ['transform-async-to-generator', 'transform-strict-mode', 'transform-object-assign', 'transform-decorators-legacy', 'react-hot-loader/babel'],
        presets: ['es2015', 'react', 'stage-0'],
      },
    },
    {
      test: /\.css$/,
      use: [
        'style-loader',
        'css-loader',
      ],
    },
    {
      test: /\.(png|svg|jpg|gif)$/,
      use: [
        'file-loader',
      ],
    },
    {
      test: /\.(woff|woff2|eot|ttf|otf)$/,
      use: [
        'file-loader',
      ],
    },
    {
      test: /\.(csv|tsv)$/,
      use: [
        'csv-loader',
      ],
    },
    {
      test: /\.xml$/,
      use: [
        'xml-loader',
      ],
    },
    ],
  },
  resolve: {
    extensions: ['.js', '.jsx'], // 这里是必须要加的，不然默认的值加载['.js','.json']为后缀的文件
    alias: {
      Actions: path.resolve(__dirname, 'src/actions'),
    },
  },
};

if (process.env.NODE_ENV === 'production') {
  config = Object.assign({}, config, {
    mode: 'production',
  });
} else {
  const {
    plugins,
  } = config;
  plugins.push(new webpack.DefinePlugin({
    'global.GENTLY': false,
    __DEV__: true,
  }));
  config = Object.assign({}, config, {
    mode: 'development',
    devtool: 'eval',
    devServer: {
      hot: true,
      contentBase: path.join(__dirname, 'dist'),
      compress: true,
      port: 8083,
      historyApiFallback: {
        rewrites: [{
          from: /^\/$/,
          to: './index.html',
        },
        ],
      },
    },
    plugins,
  });
}

module.exports = config;

重新执行
