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;
