对于我的一条路线,我当前的路线描述如下:

<Route path='auth' component = {AuthenticateContainer} onEnter = {checkAuth}/>

为了拆分路由路径的代码,我相信代码可能如下所示:

                <Route path="auth"  getComponent={(nextState, callback) => {
                    require.ensure([], function(require) {
                        callback(null, require('./AuthenticateContainer.js').default);
                    })
                }}/>

但是我缺少的是 OnEnter checkAuth 函数,我该如何包含它?

如果你有checkAuth./AuthenticationContainer.js那么将它移动到routes.js或创建一个新的 js 文件并在 routes.js 中需要它。基本上,onEnter在需要使用getComponent.

我的 routes.js 看起来像这样-

import React from 'react';
import { Route } from 'react-router';

export default (store) => {
  function requireAuth(nextState, replace) {
    if(!store.getState().auth.isAuthenticated) {
      replace({
        pathname: '/',
        state: { nextPathname: nextState.location.pathname }
      })
    }
  }

  return { childRoutes: [{
      path: '/',
      getComponents(location, callback) {
        require.ensure(['./containers/App/App.jsx'], function (require) {
            callback(null, require('./containers/App/App.jsx').default)
        })
      },
      childRoutes: [{
        path: 'about',
        onEnter: requireAuth,
        getComponents(location, callback) {
          require.ensure(['./containers/About/About.jsx'], function (require) {
              callback(null, require('./containers/About/About.jsx').default)
          })
        }
      }]
    }]
  }
};

我不确定您是否可以checkAuth在内部调用require.ensure并在未通过身份验证的情况下停止加载组件。按照设计,这是一种不好的方法,因为您正在加载组件然后检查它是否经过身份验证。这否定了代码拆分的好处。

编辑 - 添加 webpack.config.js

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

var BUILD_DIR = path.resolve(__dirname, 'build');
var APP_DIR = path.resolve(__dirname, 'src');

var config = {
  entry: APP_DIR + '/index.jsx',

  output: {
    path: BUILD_DIR,
    filename: 'bundle.js',
    chunkFilename: '[id].chunk.js',
  },

  devtool: 'inline-source-map',

  module : {
    loaders : [
      {
        test : /\.jsx?/,
        include : APP_DIR,
        loader : 'babel'
      },
      {
        test: /\.css?$/,
        loaders: [ 'style', 'raw' ],
        include: __dirname
      }
    ]
  },

  plugins: [
    new webpack.optimize.CommonsChunkPlugin('shared.js')
  ]
};

module.exports = config;

Webpack 构建输出 -
