javascript – React App：使用React服务器启动API服务器

我正在研究一个非常简单的react应用程序(我的第一个),但我无法弄清楚如何让API和反应服务器启动……

我正在使用react-router用于客户端路由,并且我在另一个项目上使用了express,所以我用它来启动我的React项目来设置API.

但我想知道是否有办法使用react-router处理API路由并返回一些数据……

我用Google搜索并环顾四周,但我似乎可以找到任何相关信息(也不确认或反驳).

有没有人对此有任何意见？
(我知道这不是一个正确的问题,但我似乎无法找到任何信息来关闭唠叨的奇迹)

解决方法:

有一种方法可以启动API服务器并做出反应.在我的案例server.js中的快速主文件中.您需要安装webpack-dev-middleware和webpack-hot-middleware.

// server.js
import path from 'path';
import express from 'express';
import webpack from 'webpack';
import webpackDevMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import config from './webpack.config';

const app = express(),
  DIST_DIR = path.join(__dirname, 'client'),
  HTML_FILE = path.join(DIST_DIR, 'index.html'),
  compiler = webpack(config),
  isDevelopment = process.env.NODE_ENV === 'development';

if (isDevelopment) {
  app.use(webpackDevMiddleware(compiler, {
    publicPath: config.output.publicPath,
  }));

  app.use(webpackHotMiddleware(compiler));
} else {
  app.use(express.static(DIST_DIR));
}

app.get('/', (req, res) => res.sendFile(HTML_FILE));
app.get('*', (req, res) => res.redirect(301, '/'));

app.listen(process.env.PORT || 4200);

然后在您的webpack.config.js中,您可以按照以下设置进行操作：

const path = require('path');
const webpack = require('webpack');

process.env.NODE_ENV = process.env.NODE_ENV || 'development';

module.exports = {
  entry: [
    'webpack-hot-middleware/client',
    './app/app.jsx',
  ],
  externals: {
    jquery: 'jQuery',
    'react/addons': 'react',
    'react/lib/ExecutionEnvironment': 'react',
    'react/lib/ReactContext': 'react',
  },
  output: {
    path: path.resolve(__dirname, 'client'),
    filename: 'bundle.js',
    publicPath: '/',
    sourceMapFilename: 'bundle.map',
  },
  devtool: process.env.NODE_ENV === 'production'
    ? undefined : 'cheap-module-eval-source-map',
  resolve: {
    modules: ['node_modules', './app/components'],
    extensions: ['.js', '.jsx'],
  },
  module: {
    rules: [
      {
        test: /(\.js$|\.jsx$)/,
        exclude: /(node_modules|bower_components)/,
        use: [
          {
            loader: 'babel-loader',
            options: {
              presets: ['react', 'es2015', 'stage-0', 'airbnb'],
            },
          },
        ],
      },
      {
        test: /\.scss$/,
        use: ['style-loader', 'css-loader', 'sass-loader'],
      },
      {
        test: /\.(eot|svg|ttf|woff|woff2)(\?v=\d+\.\d+\.\d+)?$/,
        use: {
          loader: 'file-loader',
          options: {
            name: '[name].[ext]'
          }
        }
      }
    ],
  },
  plugins: [
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery',
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      minimize: true,
      compressor: {
        warnings: false,
      },
    }),
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify(process.env.NODE_ENV)
      },
    }),
  ],
};

然后在你的package.json脚本中：

// package.json
"scripts": {
    "build": "webpack",
    "postinstall": "npm run build",
    "start": "babel-node server.js",
    "start:dev": "nodemon -e js --exec babel-node -- ./server.js",
    "test": "karma start"
  }

现在,当您启动Express服务器时,您的API和react将一起运行.
