在同一个项目中进行本机反应

Question

你好，

我有一个项目的web使用反应和本地使用反应本地和共享一些代码。

react native正在工作，但是如果我删除web版本正在工作的react native代码和库，则web版本在同一代码库中不工作。

我认为问题是在webpack配置，我已经尝试了很多版本，但在鼻涕工作。

要让web启动我使用的服务器，请执行以下操作：

"webpack-dev-server --content-base dist/ --config webpack/web.dev.config.js --port 3000 --inline --hot --colors --historyApiFallback",

我的webpack配置文件：

const path = require('path')
const webpack = require('webpack')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const autoprefixer = require('autoprefixer')

const extractLess = new ExtractTextPlugin('css/style_webpack.css')

module.exports = {
  devtool: 'eval',
  entry: [path.resolve(__dirname, '../src/web/index')],
  cache: true,
  output: {
    path: path.join(__dirname, '../dist'),
    filename: 'bundle.js',
  },
  module: {
    loaders: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        query: {
          plugins: [
            'transform-object-rest-spread',
            'transform-class-properties',
          ],
          presets: ['es2015', 'react', 'stage-0'],
        },
        include: path.resolve(__dirname, '../src')
      },
      {
        test: /\.less$/i,
        loader: extractLess.extract([
          {
            loader: 'raw-loader',
            options: {
              minimize: false,
              sourceMap: false,
            },
          },
          {
            loader: 'postcss-loader',
            options: {
              plugins: function() {
                return [autoprefixer('>1%', 'ie 10')]
              },
            },
          },
          {
            loader: 'less-loader',
            options: {
              strictMath: false,
              noIeCompat: true,
            },
          },
        ]),
      },
    ],
  },
  plugins: [
    extractLess,
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify('development'),
        PLATFORM_ENV: JSON.stringify('web'),
      },
    }),
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
  ],
}

还有一些错误：

Answer 1

如果您在两个项目之间共享相同的代码，那么连接点就是您在这两个项目中都使用了ReactJS。这意味着您可以获取代码并创建公共模块化服务/Util类，您可以将这些类导入到这两个模块中。

考虑以下几点：

我有一个用户api调用在ReactJS和React本地应用程序。我创建了一个用户服务模块，它只用我需要的核心导入来处理这个问题（用JavaScript编写）。然后，我将此服务导入到我的反应和反应本地应用程序中。

你为什么要拆开你的申请？你有了共享的代码，就把普通代码分离出来，并将其模块化。如果没有看到你的代码，很难判断。

Answer 2

你不能简单地混合反应和反应本机（在这里阅读为什么）。要么按照Cherniv的建议使用React Native Web，要么将代码完全拆分。

如果您想执行前者，请参阅本回购协议，以获取95%代码重用的示例。
