webpack-4

问题 Just upgraded to Webpack 4 and when building my server side code with mode:'production' .I get this MySQL Error: Received packet in the wrong sequence. How can you prevent such mangling from happening? 回答1: I have faced the same problem when bundling with web pack. at last i have solved the issue. i think it is an issue related to web-pack and babel-loader version mismatch. i suggest following combinations in package.json "babel-core": "^6.26.0", "babel-loader": "^7.1.2", "babel-plugin

问题 Per the tippy.js git hub page I installed it with npm: npm i tippy.js Now I have a .js source file that's used for a webpack 4 html page that gets output to my ./dist folder, but I don't know how to import it; my other option is just to include it from the CDN but that doesn't seem very webpackesque Also I'm using ES6 via babel-loader stage-0; so how exactly do I import that in so it's included with my bundle? Shouldn't the CSS for tippy need to be imported as well? 回答1: Okay I found it here

问题 I am using MiniCssExtractPlugin to lazyload css files in my react application. i have given publicPath option for MiniCssExtractPlugin but it is not taking this option value, it is taking output.publicPath option. config: { test: /\.(css)?$/, use: [{ loader : MiniCssExtractPlugin.loader, options : { publicPath : '../' } }, 'css-loader' ], } Any help??? 回答1: Seems as though your not the only one confused, 52 comments on how to get this right.

问题 I have my own json-loader which I want to use instead of the built-in loader. This used to work in webpack-3; in webpack-4 my loader gets called but the results get passed to the built-in loader, which then errors out because what it's being fed is JS source, not json. How can I prevent the buit-in json-loader being called? My webpack.cofig.ts looks like this: import * as webpack from 'webpack' import * as path from 'path' const config = { mode: 'production', node: { fs: 'empty' },

问题 Just setting up one of my projects with webpack, first time using it so just getting my head around it. Basically i've got the SCSS compiling into CSS, but previously when I was using grunt there was sourcemap setting where if you're inspecting the element it would show you what .scss file the element was being pulled from even though it was compiled into a CSS file. Here is my webpack config: var debug = process.env.NODE_ENV !== "production"; var webpack = require('webpack'); module.exports

问题 I am dynamically calling an import statement in my typescript code, based on that webpack will create chunks like below: you can see Webpack is automatically generating the file name as 1,2,3 respectively, the name is not a friendly name I have tried a way to provide the chunk name through comment, but it's generating modulename1.bundle.js , modulename2.bundle.js bootStrapApps(config) { config.apps.forEach(element => { registerApplication( // Name of our single-spa application element.name, /

问题 I tried to upgrade Webpack and babel to 4, 7 respectively but couldn’t make it work. Also the official doc isn’t helping much with the upgrade I am getting following issue compiler error: ERROR in Cannot find module '@babel/core' @ multi main dependencies I am using: "babel-core": "^6.26.3", "babel-eslint": "^9.0.0", "babel-loader": "^8.0.0", "babel-plugin-transform-class-properties": "^6.24.1", "babel-plugin-transform-object-rest-spread": "^6.26.0", "babel-polyfill": "^6.26.0", "babel-preset

问题 This article webpack 4: mode and optimization seems to suggest that when mode is set to development the devtool is set to eval . I was expecting this to trigger sourcemap generation but running the webpack-4-quickstart in either development or production mode results in no sourcemaps being generated. How can I generate sourcemaps with webpack 4? 回答1: I think what you are expecting is extracted file including source maps like 'bundle.js.map', but eval type doesn't generate separate file: eval

问题 In a webpack 3 configuration I would use the code below to create separate vendor.js chunk: entry: { client: ['./client.js'], vendor: ['babel-polyfill', 'react', 'react-dom', 'redux'], }, output: { filename: '[name].[chunkhash].bundle.js', path: '../dist', chunkFilename: '[name].[chunkhash].bundle.js', publicPath: '/', }, plugins: [ new webpack.HashedModuleIdsPlugin(), new webpack.optimize.CommonsChunkPlugin({ name: 'vendor', }), new webpack.optimize.CommonsChunkPlugin({ name: 'runtime', }),
