First make sure to install cross-env
npm i cross-env --save-dev
Look at the directory structure:
1. Create a new test.js file in the build folder and copy the content of build.js. Modify a place. process.env.NODE_ENV ='test' and const webpackConfig = require('./webpack.test.conf')
'use strict'
require('./check-versions')()
process.env.NODE_ENV = 'test' //修改这里
const ora = require('ora')
const rm = require('rimraf')
const path = require('path')
const chalk = require('chalk')
const webpack = require('webpack')
const config = require('../config')
const webpackConfig = require('./webpack.test.conf') //还有这里
const spinner = ora('building for production...')
spinner.start()
rm(path.join(config.build.assetsRoot, config.build.assetsSubDirectory), err => {
if (err) throw err
webpack(webpackConfig, (err, stats) => {
spinner.stop()
if (err) throw err
process.stdout.write(stats.toString({
colors: true,
modules: false,
children: false, // If you are using ts-loader, setting this to true will make TypeScript errors show up during build.
chunks: false,
chunkModules: false
}) + '\n\n')
if (stats.hasErrors()) {
console.log(chalk.red(' Build failed with errors.\n'))
process.exit(1)
}
console.log(chalk.cyan(' Build complete.\n'))
console.log(chalk.yellow(
' Tip: built files are meant to be served over an HTTP server.\n' +
' Opening index.html over file:// won\'t work.\n'
))
})
})
2. Create a new webpack.test.conf.js in the build folder, and copy webpack.prod.conf.js as well. Modify a content const env = require ('…/config/test.env')
'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
const env = require('../config/test.env') //修改这里
const webpackConfig = merge(baseWebpackConfig, {
module: {
rules: utils.styleLoaders({
sourceMap: config.build.productionSourceMap,
extract: true,
usePostCSS: true
})
},
devtool: config.build.productionSourceMap ? config.build.devtool : false,
output: {
path: config.build.assetsRoot,
filename: utils.assetsPath('js/[name].[chunkhash].js'),
chunkFilename: utils.assetsPath('js/[id].[chunkhash].js'),
},
plugins: [
// http://vuejs.github.io/vue-loader/en/workflow/production.html
new webpack.DefinePlugin({
'process.env': env
}),
new UglifyJsPlugin({
uglifyOptions: {
compress: {
warnings: false
}
},
sourceMap: config.build.productionSourceMap,
parallel: true
}),
// extract css into its own file
new ExtractTextPlugin({
filename: utils.assetsPath('css/[name].[contenthash].css'),
allChunks: true,
})，
new OptimizeCSSPlugin({
cssProcessorOptions: config.build.productionSourceMap ? {
safe: true, map: {
inline: false } } : {
safe: true }
}),
new HtmlWebpackPlugin({
filename: config.build.index,
template: 'index.html',
inject: true,
minify: {
removeComments: true,
collapseWhitespace: true,
removeAttributeQuotes: true
},
chunksSortMode: 'dependency'
}),
new webpack.HashedModuleIdsPlugin(),
new webpack.optimize.ModuleConcatenationPlugin(),
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
minChunks(module) {
return (
module.resource &&
/\.js$/.test(module.resource) &&
module.resource.indexOf(
path.join(__dirname, '../node_modules')
) === 0
)
}
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'manifest',
minChunks: Infinity
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'app',
async: 'vendor-async',
children: true,
minChunks: 3
}),
// copy custom static assets
new CopyWebpackPlugin([{
from: path.resolve(__dirname, '../static'),
to: config.build.assetsSubDirectory,
ignore: ['.*']
}])
]
})
if (config.build.productionGzip) {
const CompressionWebpackPlugin = require('compression-webpack-plugin')
webpackConfig.plugins.push(
new CompressionWebpackPlugin({
asset: '[path].gz[query]',
algorithm: 'gzip',
test: new RegExp(
'\\.(' +
config.build.productionGzipExtensions.join('|') +
')$'
),
threshold: 10240,
minRatio: 0.8
})
)
}
if (config.build.bundleAnalyzerReport) {
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}
module.exports = webpackConfig
3. Modify the utils.js file in the build folder so that the configuration of the packaged test package is the same as the official package
exports.assetsPath = function(_path) {
const assetsSubDirectory = process.env.NODE_ENV === 'production' || process.env.NODE_ENV === 'test' ?
config.build.assetsSubDirectory :
config.dev.assetsSubDirectory
return path.posix.join(assetsSubDirectory, _path)
}
4. Modify webpack.base.conf.js in the build folder so that the configuration of the packaged test package is the same as the official package
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production' || process.env.NODE_ENV === "test" ?
config.build.assetsPublicPath : config.dev.assetsPublicPath
},
5. Modify the packaging configuration in index.js under config. According to process.env.NODE_ENV, the packaged test package and the official package are distinguished and packaged into different files.
build: {
// Template for index.html
index: process.env.NODE_ENV === 'test' ? path.resolve(__dirname, '../test/index.html') : path.resolve(__dirname, '../dist/index.html'), //测试包与正式包入口文件路径区分
// Paths
assetsRoot: process.env.NODE_ENV === 'test' ? path.resolve(__dirname, '../test') : path.resolve(__dirname, '../dist'), //测试包也正式包打包后文件区分
assetsSubDirectory: 'static',
assetsPublicPath: './', //history模式下要写成 /
productionSourceMap: false,
devtool: '#source-map',
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
bundleAnalyzerReport: process.env.npm_config_report
}
6. Prod.env.js configuration under the config folder:
'use strict'
const BUILD_ENV = process.env.BUILD_ENV
module.exports = {
NODE_ENV: '"production"',
BUILD_ENV: '"' + BUILD_ENV + '"',
baseUrl: '"正式服请求地址"'
}
7. Test.env.js configuration under the config folder:
'use strict'
const BUILD_ENV = process.env.BUILD_ENV
module.exports = {
NODE_ENV: '"test"',
BUILD_ENV: '"' + BUILD_ENV + '"',
// baseUrl: '"' + baseUrl + '"',
baseUrl: '"测试服请求地址"'
}
8. In package.json, add the build:test command, or add the publish command to package the official package and the test package at the same time
"scripts": {
"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
"start": "npm run dev",
"build:prod": " node build/build.js",
"build:test": " node build/test.js",
"publish": "npm run build:prod && npm run build:test"
},
9. In the packaged axios request file: modify the request address according to the environment
axios.defaults.baseURL = process.env.baseUrl
10. Run the corresponding command and it will be fine
