javascript - 使用 webpack 和 Express.js 部署 React App

Question

我正在使用 React 开发一个应用程序，并使用 webpack 作为客户端部分的模块 bundler 。对于服务器，我使用 Express.js。

对于客户端，我使用 webpack.config.dev.js 进行配置，并使用 npm start 在 localhost:3000 启动 Web 服务器。

对于服务器，我有app.js文件，我使用node bin/www来启动express服务器，但我必须提供不同的端口来启动服务器，在此案例，本地主机:3100。

我只有一个用于客户端和服务器的 package.json。

有没有办法将客户端和服务器部署在同一个域中？如果是这样，我该怎么办？我希望从我的客户端代码中将端点引用为:/data/users，而不是执行 localhost:3100/data/users。

请参阅下面的 webpack 配置、express 配置和 package.json(如果有帮助):

webpack.config.dev.js:

import webpack from 'webpack';

服务器端的app.js:

var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
var users = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/users', users);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


module.exports = app;

也许these样板可以帮助你。和here第 37 行就是您要查找的内容。

What initially gets run is bin/server.js, which does little more than enable ES6 and ES7 awesomeness in the server-side node code. It then initiates server.js. In server.js we proxy any requests to /api/* to the API server, running at localhost:3030. All the data fetching calls from the client go to /api/*. Aside from serving the favicon and static content from /static, the only thing server.js does is initiate delegate rendering to react-router. At the bottom of server.js, we listen to port 3000 and initiate the API server.
