我正在尝试为我正在处理的反应应用程序实现服务器端路由.我正在使用react-router用于此目的.这是我的server.js代码的一部分

const renderToString   = require ('react-dom/server');
let match,RouterContext = require('react-router');
const routes = require ('/app/router');
const React = require('react');

app.get('*',(req,res) => {
    match(
        { routes,location: req.url },(err,redirectLocation,renderProps) => {

            // in case of error display the error message
            if (err) {
                return res.status(500).send(err.message);
            }

            // in case of redirect propagate the redirect to the browser
            if (redirectLocation) {
                return res.redirect(302,redirectLocation.pathname + redirectLocation.search);
            }

            // generate the React markup for the current route
            let markup;
            if (renderProps) {
                // if the current route matched we have renderProps
                markup = renderToString(<RouterContext {...renderProps}/>);
            } else {
                // otherwise we can render a 404 page
                markup = renderToString(<NotFoundPage/>);
                res.status(404);
            }

            // render the index template with the embedded React markup
            return res.render('index',{ markup });
        }
    );
});



//my webpack config file 

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

module.exports = {
  entry: [
    'script!jquery/dist/jquery.min.js','script!foundation-sites/dist/foundation.min.js','./app/app.jsx'
  ],externals: {
    jquery: 'jQuery'
  },plugins: [
    new webpack.ProvidePlugin({
      '$': 'jquery','jQuery': 'jquery'
    })
  ],output: {
    path: __dirname,filename: './public/bundle.js'
  },resolve: {
    root: __dirname,modulesDirectories: [
      'node_modules','./app/components'
    ],extensions: ['','.js','.jsx']
  },module: {
    loaders: [
      {
        loader: 'babel-loader',query: {
          presets: ['react','es2015','stage-0']
        },test: /\.jsx?$/,exclude: /(node_modules|bower_components)/
      }
    ]
  },sassLoader: {
    includePaths: [
      path.resolve(__dirname,'./node_modules/foundation-sites/scss')
    ]
  },devtool: 'cheap-module-eval-source-map'
};

我得到了一个意外的令牌< at< RouterContext {... renderProps} />.

我已经查看了教程,我正在工作,但我不太确定我做错了什么.任何建议都会非常感激

解决方法

您使用的是Babel预设 react,es2015和 stage-0.

这些预设中没有一个包含您使用object spread syntax所需的插件 – 这部分代码：

<RouterContext {...renderProps} />

您可以通过将transform-object-rest-spread插件添加到您的Babel配置来解决您的问题,如下所示：

module: {
    loaders: [
        {
            loader: 'babel-loader',query: {
                presets: ['react','stage-0'],plugins: ['transform-object-rest-spread']
            },exclude: /(node_modules|bower_components)/
        }
    ]
}

不要忘记使用安装插件

npm install --save-dev babel-plugin-transform-object-rest-spread
