Vue CLi3Modify webpackconfiguration
Review the webpack configuration of the project
Because @vue/cli-serviceof the configuration webpack abstract, when you want to see webpack configuration can use inspectthe command:
vue inspect # 在终端打印 webpack配置信息
vue inspect > output.js # 把webpack配置信息生成到output.js文件
Note that the output.jsfile is not a valid webpack configuration file and is only for review.
Modify webpack configuration
Take modifying the path alias as an example:
-
Create a file in the project root directory
vue.config.js -
Refer to the following code to modify the path alias:
// vue.config.js
const path = require('path')
const resolve = dir => path.resolve(__dirname, dir)
module.exports = {
chainWebpack: config => {
config.resolve.alias
.set('styles', resolve('src/assets/styles'))
}
}
reference
-
Configuration example:
const path = require('path')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
const ProxyAgent = require('proxy-agent')
const resolve = dir => path.resolve(__dirname, dir)
module.exports = {
outputDir: process.env.outputDir || 'dist', // 'dist', 生产环境构建文件的目录
runtimeCompiler: true,
assetsDir: 'static',
productionSourceMap: false, // 生产环境的 source map
parallel: require('os').cpus().length > 1,

// 公共配置
