这是我的webpack.config.js
var webpack = require("webpack");
module.exports = {
entry: "./entry.js",
devtool: "source-map",
output: {
path: "./dist",
filename: "bundle.min.js"
},
plugins: [
new webpack.optimize.UglifyJsPlugin({minimize: true})
]
};
我用
$ webpack
在dist文件夹里,我只得到
bundle.min.js
bundle.min.js.map
我还想看看未压缩的bundle.js
也许我来晚了,但我也有同样的问题,所以我为此写了一个unminifiedwebpack插件。
安装
npm install --save-dev unminified-webpack-plugin
使用
var path = require('path');
var webpack = require('webpack');
var UnminifiedWebpackPlugin = require('unminified-webpack-plugin');
module.exports = {
entry: {
index: './src/index.js'
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'library.min.js'
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
}),
new UnminifiedWebpackPlugin()
]
};
通过上述操作,您将得到library.min.js和library.js两个文件。不需要执行webpack两次,它只是工作!^ ^
我也有同样的问题,必须满足以下所有要求:
缩小版+非缩小版(如问题所示)
ES6
跨平台(Windows + Linux)。
我最终解决如下:
webpack.config.js:
const path = require('path');
const MinifyPlugin = require("babel-minify-webpack-plugin");
module.exports = getConfiguration;
function getConfiguration(env) {
var outFile;
var plugins = [];
if (env === 'prod') {
outFile = 'mylib.dev';
plugins.push(new MinifyPlugin());
} else {
if (env !== 'dev') {
console.log('Unknown env ' + env + '. Defaults to dev');
}
outFile = 'mylib.dev.debug';
}
var entry = {};
entry[outFile] = './src/mylib-entry.js';
return {
entry: entry,
plugins: plugins,
output: {
filename: '[name].js',
path: __dirname
}
};
}
package.json:
{
"name": "mylib.js",
...
"scripts": {
"build": "npm-run-all webpack-prod webpack-dev",
"webpack-prod": "npx webpack --env=prod",
"webpack-dev": "npx webpack --env=dev"
},
"devDependencies": {
...
"babel-minify-webpack-plugin": "^0.2.0",
"npm-run-all": "^4.1.2",
"webpack": "^3.10.0"
}
}
然后我可以通过(不要忘记npm install之前):
npm run-script build
也许我来晚了,但我也有同样的问题,所以我为此写了一个unminifiedwebpack插件。
安装
npm install --save-dev unminified-webpack-plugin
使用
var path = require('path');
var webpack = require('webpack');
var UnminifiedWebpackPlugin = require('unminified-webpack-plugin');
module.exports = {
entry: {
index: './src/index.js'
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'library.min.js'
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
}),
new UnminifiedWebpackPlugin()
]
};

你可以在webpack配置中定义两个入口点,一个用于普通js,另一个用于迷你js。然后你应该输出你的bundle和它的名字,并配置UglifyJS插件来包含min.js文件。请参阅webpack配置示例了解更多细节:
module.exports = {
entry: {
'bundle': './src/index.js',
'bundle.min': './src/index.js',
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: "[name].js"
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
include: /\.min\.js$/,
minimize: true
})
]
};
运行webpack后,你会在dist文件夹中得到bundle.js和bundle.min.js,不需要额外的插件。
你可以这样格式化你的webpack.config.js:
var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');
module.exports = {
context: __dirname,
devtool: debug ? "inline-sourcemap" : null,
entry: "./entry.js",
output: {
path: __dirname + "/dist",
filename: "library.min.js"
},
plugins: debug ? [] : [
new webpack.optimize.DedupePlugin(),
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
],
};'
然后构建它的非最小化运行(在项目的主目录中):
$ webpack
要构建它的最小化运行:
$ NODE_ENV=production webpack
注:
确保对于非简化版本,您将输出文件名更改为library.js,对于简化版本,则将输出文件名更改为library.min.js,以便它们不会相互覆盖。
