有一个问题,并且无法以任何方式找到解决方案,因为很长一段时间直接我没有处理webpack设置。
用户的错误来自我在React上编写的小部件连接的门户网站。 例如,我的一些用户收到此错误:
{
"message": "Loading chunk 0 failed.",
"stack": "Error: Loading chunk 0 failed.\n at HTMLScriptElement.n (http://<url>/widget/media/index.js:2:500)"
}
或
{
"message": "Loading chunk 1 failed.",
"stack": "Error: Loading chunk 0 failed.\n at HTMLScriptElement.n (http://<url>/widget/media/index.js:2:500)"
}
生产它在这样的链上更新:在服务器的开头,build:prod命令 在这里包装&#34; build:prod&#34;推出:&#34; npm run lint&amp; &安培; npm test&amp; &安培; webpack - config webpack.config.prod.js&#34; ,然后 webpack.config.prod.js , 在这里这样的代码
const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const pkg = require('./package.json');
module.exports = {
entry: {
index: path.join(__dirname, 'src', 'index.js')
},
output: {
path: path.join(__dirname, 'build'),
filename: '[name].js',
chunkFilename: '[name].js',
publicPath: '/widget/media/'
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.(png|jpg)$/,
use: 'file-loader?name=img/[name].[ext]'
},
{
test: /\.css$/,
loader: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [
{
loader: 'css-loader',
options: {
sourceMap: false,
modules: true,
minimize: true,
localIdentName: '[hash:base64:7]'
}
},
'postcss-loader'
]
})
}
]
},
plugins: [
new ExtractTextPlugin('styles.css'),
new webpack.NoEmitOnErrorsPlugin(),
new webpack.optimize.UglifyJsPlugin({
compress: { warnings: false },
comments: false
}),
new webpack.BannerPlugin(`${pkg.name}-${new Date()}. RELEASE.`),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify('production')
},
PROJECT_ENV: JSON.stringify('production')
})
]
};
在index.js文件中,在src文件夹中指定为我的入口索引这样的代码
import 'babel-polyfill';
import datasetPolyfill from 'element-dataset';
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import store from './store';
import Orders, { initAction } from './features/orders';
import Returns, { initAction as returnInit } from './features/returns';
datasetPolyfill();
const features = {
orders: {
root: Orders,
init: initAction
},
returns: {
root: Returns,
init: returnInit
}
};
const containers = Array.from(document.querySelectorAll('[data-feature]'));
containers.forEach(container => {
const Feature = features[container.dataset.feature];
if (Feature) {
store.dispatch(Feature.init(JSON.parse(container.dataset.state)));
render(
<Provider store={store}>
<Feature.root />
</Provider>,
container
);
}
});
在这段代码中,我找到了专家的所有功能。此外,在导入订单文件中,{initAction}来自&#39; ./ features / orders&#39; 在这里给我这样的代码
import errorAction from 'rossko-orders/lib/actions/error';
import AsyncComponent from '../../components/async-wrap';
function importFunc() {
return import(/* webpackChunkName: "orders" */ 'rossko-orders');
}
export initAction from 'rossko-orders/lib/actions/init';
export default AsyncComponent(importFunc, errorAction);
同样的代码(返回而不是订单) import返回,{initAction as returnInit}来自&#39; ./ features / returns&#39 ;;
判断错误发生了什么,不是所有用户,而只是某些部分。此外,围绕此类错误的测试通常不会。
UPD:起初我认为是因为某些用户拥有旧浏览器(例如IE)。但正如展示更深入的分析,错误也出现在现代浏览器上。例如:

我不知道如何解决这个问题。任何帮助都将非常有价值。 THX。
